You redeemed an Amazon gift card on the wrong account. Or your child has a balance they cannot use. Or you want to combine two Amazon accounts before making one larger purchase. Then you look for the transfer button and find… nothing. That is when the question gets frustrating: can you transfer Amazon gift card balance to another account, or is the money stuck?
The short answer: no, you generally cannot transfer Amazon gift card balance to another Amazon account after the claim code has been redeemed. Amazon gift card balance stays tied to the account where it was applied. You also usually cannot move it to another country’s Amazon marketplace, cash it out, send it to PayPal, or use it to buy another gift card. The safer options are to use the balance on the original account, buy eligible items for the other person, share Prime benefits through Amazon Household where relevant, or contact Amazon support if you redeemed a card to the wrong account by mistake.

So, can you transfer Amazon gift card balance to another account?
No. Once an Amazon gift card is redeemed, the balance usually cannot be transferred to another Amazon account. Amazon’s gift card terms say that no portion of an Amazon.com balance may be transferred to another Amazon.com account. Amazon’s gift card restriction pages also explain that a gift card cannot be transferred to another account after the claim code has been redeemed.
That means the account that redeemed the code owns that balance for Amazon shopping. If you redeem a $100 Amazon gift card on Account A, you cannot simply move that $100 to Account B.
So the direct answer to can you transfer Amazon gift card balance to another account is no. There is no official transfer button, no balance-send feature, no “gift this balance” setting, and no normal self-service method.
This is different from sending someone a new, unredeemed Amazon gift card. A new card can be given to anyone before redemption. A redeemed balance is different. It has already become part of one account.
Why Amazon does not allow gift card balance transfers
Amazon gift card balances work like stored value inside one Amazon account. Once redeemed, Amazon ties the value to that account for security, fraud prevention, refund tracking, and marketplace controls.
If Amazon allowed easy balance transfers, scammers would have a much easier time moving stolen gift card money between accounts. Gift card fraud is already common. Scammers pressure people into buying Amazon gift cards and sharing claim codes. Once the scammer redeems the code, the money is very hard to recover. Transferable balances would make that problem worse.
Transfer limits also reduce account-trading, money laundering, resale abuse, refund abuse, and unauthorized access. They make gift cards less flexible, yes. But they also make stolen balance harder to move around.
That is annoying when you make an honest mistake. But it is part of why Amazon treats redeemed balances as locked to the account.
Redeemed vs unredeemed Amazon gift cards
The whole issue depends on whether the card has been redeemed.
An unredeemed Amazon gift card is still flexible. You can give the claim code or physical card to the intended person. They can redeem it on their own Amazon account. That is the normal way to “transfer” gift card value before it becomes account balance.
A redeemed Amazon gift card is different. Once the code enters an Amazon account successfully, the value becomes Amazon balance. That balance generally cannot move to another account.
Comparison table 1: unredeemed gift card vs redeemed balance
| Situation | Can someone else use it? | What to do |
|---|---|---|
| Physical Amazon gift card not redeemed | Yes | Give the card to the intended person |
| Digital Amazon gift card not redeemed | Yes | Forward only to the trusted recipient |
| Claim code visible but unused | Yes, but risky | Share only with the intended recipient |
| Gift card redeemed to your account | Usually no transfer | Use it from your account |
| Gift card redeemed to wrong account | Usually no self-service transfer | Contact Amazon support quickly |
| Amazon balance from refunded gift card purchase | Usually locked to account | Use it on eligible Amazon purchases |
| Amazon promotional credit | Usually more restricted | Use before expiration and only on eligible items |
If you have not redeemed the card yet, stop and check which account you are logged into. That one-second check prevents the whole problem.
What to do if you redeemed an Amazon gift card to the wrong account
If you redeemed the card to the wrong account, act quickly. Do not spend the balance. Do not close the account. Do not try weird workarounds. Contact Amazon customer service from the account where the gift card was redeemed and explain the mistake.
Be realistic, though. Amazon’s standard policy says redeemed gift card balance cannot be transferred. Support may not be able to move it. In rare mistake cases, especially when the balance is unused and both accounts belong to you, support may review the situation. But you should not count on it.
When you contact support, keep it simple:
I accidentally redeemed an Amazon gift card to the wrong Amazon account. The balance has not been spent. I intended to redeem it on my other account. Can you review whether anything can be done?
Have these details ready:
| Detail | Why it helps |
|---|---|
| Gift card claim code | Helps Amazon locate the redemption |
| Redemption date | Narrows the activity |
| Amount | Confirms value |
| Order/email receipt if digital | Shows ownership |
| Physical card receipt if store-bought | Helps prove purchase |
| Account where it was redeemed | Amazon needs to verify account activity |
| Intended account email | Helps explain the mistake |
| Confirmation balance is unused | Gives support fewer complications |
Do not expect a guaranteed transfer. But if there is any chance of help, quick support contact is better than waiting weeks.
Can Amazon support transfer gift card balance?
Usually, no. Amazon’s policy says redeemed balances cannot be transferred between accounts. Customer support generally follows that policy.
However, support can sometimes help investigate issues such as wrong redemption, stolen claim codes, suspicious account activity, or gift card redemption problems. That does not mean they will move balance between accounts, but they may review the case.
The difference matters:
- “I changed my mind and want the balance on another account” — usually no.
- “I accidentally redeemed this unused card to my old account five minutes ago” — support may review, but no guarantee.
- “A scammer stole my code and redeemed it” — report immediately, but recovery is uncertain.
- “I want to combine balances from two accounts” — usually no.
- “I want to move U.S. Amazon balance to Amazon UK” — no.
So, can you transfer Amazon gift card balance to another account by contacting support? As a normal request, no. As an error investigation, you can ask, but you should expect Amazon’s no-transfer rule to apply.
Can you combine gift card balances from two Amazon accounts?
No, not directly. Amazon does not let you merge gift card balances from two accounts into one balance.
This comes up often when people have old accounts, family accounts, business accounts, student accounts, or country-specific accounts. One account has $12.46. Another has $80. You want one $92.46 balance. Amazon does not provide that.
The workaround is to use each balance separately from its own account. For example, Account A can buy one item, and Account B can buy another. Or one account can buy an eligible item and ship it to the other person.
If you need one expensive item and no single account has enough balance, you may need to pay the difference with another payment method from the account that holds the larger balance. You cannot pool two account balances into one checkout.
Comparison table 2: what you can and cannot combine
| Goal | Can you do it? | Better option |
|---|---|---|
| Combine balances from two accounts | No | Use each account separately |
| Move balance from old account to new account | Usually no | Use balance on old account |
| Add new gift card to account with existing balance | Yes | Redeem new card on correct account |
| Use gift card balance plus credit card | Usually yes | Pay remaining order total with card |
| Use two Amazon accounts for one order | No | Buy items separately |
| Transfer U.S. balance to UK account | No | Use correct marketplace gift card |
| Share Prime benefits | Sometimes | Use Amazon Household where available |
| Buy a gift for someone else with your balance | Usually yes | Ship eligible item to recipient |
Can you use your Amazon balance to buy something for someone else?
Yes, this is the most practical workaround. You may not be able to transfer Amazon gift card balance, but you can often use the balance to buy eligible products and ship them to someone else.
For example, if you have $50 in Amazon balance and want to give it to your sister, you cannot send her the balance. But you can ask what she wants, buy it from your account, and ship it to her address. You can also send a gift receipt where available.
This works well for:
- birthday gifts,
- household items,
- school supplies,
- baby registry items,
- shared family purchases,
- items for a friend,
- charity wish list items,
- dorm supplies,
- office items.
There are limits. Some items may not ship to another address. Some digital products stay tied to your account. Some purchases may show your account name or gift message. Some items may not allow gift options. And if the recipient needs to return the item, the refund may go back to your Amazon account balance, not to them.
Workaround table: using balance for someone else
| Option | Works? | Best for | Limitation |
|---|---|---|---|
| Buy item and ship to recipient | Usually yes | Physical products | Refund returns to buyer account |
| Buy from recipient’s Wish List | Usually yes | Gifts | Must use your account to purchase |
| Send new Amazon gift card with card payment | Yes | Giving flexible value | Cannot usually pay with gift card balance |
| Share account login | Bad idea | Not recommended | Privacy, payment, security risk |
| Use Amazon Household | Sometimes helpful | Sharing Prime benefits | Does not transfer balance |
| Buy digital item for someone | Sometimes | Giftable digital products | Many digital items tie to buyer account |
| Buy item and have recipient reimburse you | Yes | Shared purchases | Needs trust |
This is the closest practical answer to “transfer” without breaking Amazon’s rules.
Can you buy another Amazon gift card with Amazon gift card balance?
Usually, no. Amazon generally blocks using Amazon gift card balance to buy another Amazon gift card or many third-party gift cards. This rule prevents people from turning restricted balance into transferable cards.
So if your idea is: “I’ll use my $100 Amazon balance to buy a new $100 Amazon gift card and send it to another account,” that usually will not work.
Amazon also restricts using gift card balance for certain purchases, including some third-party gift cards, prepaid cards, or cash-equivalent products. Availability and restrictions can vary by marketplace and item type, but you should not rely on gift card balance to buy gift cards.
Comparison table 3: can Amazon balance buy these?
| Purchase type | Usually possible with Amazon gift card balance? | Notes |
|---|---|---|
| Physical products sold on Amazon | Yes | Most normal items qualify |
| Household goods | Yes | Common use |
| Books | Yes | Physical books usually qualify |
| Electronics | Yes | Check seller and restrictions |
| Amazon gift cards | Usually no | Balance cannot usually buy more gift cards |
| Third-party gift cards | Usually no or restricted | Often blocked |
| Prepaid Visa/Mastercard | Usually no | Cash-equivalent restrictions |
| Some digital content | Sometimes | Depends on content and marketplace |
| Prime membership | Sometimes, depending on marketplace and billing rules | May require backup card |
| Subscribe & Save | Sometimes | Backup payment may be needed |
If you need to give someone flexible Amazon credit, buy a new gift card with a normal payment method and send it before redemption.
Can you transfer Amazon gift card balance to a bank, PayPal, or Cash App?
No. Amazon gift card balance cannot be withdrawn to a bank account, PayPal, Cash App, Venmo, Zelle, Wise, Revolut, crypto wallet, or prepaid card.
Amazon balance is for eligible purchases on Amazon. It is not a cash wallet.
Any website, forum post, Telegram account, WhatsApp number, or “support agent” claiming they can convert Amazon balance to cash should set off every alarm bell. At best, these services are gray-market resellers who will pay less than face value. At worst, they are scams that take your account, balance, or personal information.
If you need cash, the safer option is to buy items you already planned to buy on Amazon, then use the cash you would have spent elsewhere. That is not a transfer, but it can free up money in your budget.
Can you transfer Amazon gift card balance between countries?
No. Amazon gift card balances are generally tied to a specific Amazon marketplace. Amazon.com balance is for Amazon.com. Amazon.co.uk balance is for Amazon UK. Amazon.ca balance is for Amazon Canada. Amazon.co.jp balance is for Amazon Japan.
You usually cannot move Amazon.com balance to Amazon.co.uk, even if both accounts use the same email address. You also usually cannot redeem a gift card from one country’s Amazon site into another country’s Amazon marketplace.
This is a common problem for international gifts. Someone buys a U.S. Amazon.com gift card for a friend in the UK. The friend shops on Amazon.co.uk. The card may not work there. The issue is not the friend’s account. It is the marketplace.
Country transfer table
| Balance type | Can move to another country’s Amazon? | Example |
|---|---|---|
| Amazon.com balance | No | Cannot transfer to Amazon.co.uk |
| Amazon.co.uk balance | No | Cannot transfer to Amazon.com |
| Amazon.ca balance | No | Cannot transfer to Amazon.com |
| Amazon.co.jp balance | No | Cannot transfer to Amazon.com |
| Same email on two marketplaces | Still no | Same login does not merge balances |
| New unredeemed country-specific gift card | Only on matching marketplace | Buy the recipient’s local Amazon gift card |
| International purchase from original marketplace | Sometimes | Shipping/import fees may apply |
For international gifting, always buy the gift card for the marketplace the recipient actually uses.
Can you transfer Amazon gift card balance if you close an account?
Usually, no. Closing an Amazon account can make unused balance hard or impossible to use. Do not close an account with gift card balance until you understand what will happen.
If you want to close an old account because you have a new one, spend the balance first if possible. Use it for eligible purchases, ship items to your current address, or buy gifts for someone else. After the balance is gone and orders are complete, then consider account closure.
If you already closed an account with balance, contact Amazon support. Recovery is not guaranteed. Account closure affects order history, digital content, returns, refunds, subscriptions, and gift card balance.
Can Amazon merge two accounts?
Amazon generally does not merge two retail customer accounts into one simple combined account with shared order history, gift card balance, and payment methods. There may be limited support processes for specific account issues, but you should not expect Amazon to merge balances from two personal accounts.
People often want this after creating accounts with two emails, using a student account, moving countries, or separating family accounts. Amazon may help with login recovery or account access, but gift card balance transfer remains restricted.
Use the balance on the account where it sits.
Amazon Household does not transfer gift card balance
Amazon Household lets eligible users share certain Prime benefits and digital content with another adult, teens, or children depending on country and setup. It does not merge accounts into one wallet. It does not transfer gift card balance.
This matters because many people think Household might solve the balance problem. It can help with Prime delivery benefits or family sharing, but it does not let one adult spend another adult’s Amazon gift card balance as if it were shared cash.
Comparison table 4: Amazon Household vs gift card transfer
| Feature | Amazon Household | Gift card balance transfer |
|---|---|---|
| Shares some Prime benefits | Yes, where available | No |
| Keeps separate accounts | Yes | Not relevant |
| Moves gift card balance | No | Not allowed |
| Combines order histories | No | No |
| Lets another adult use your balance directly | No | No |
| Useful for family shopping | Sometimes | Not as balance transfer |
| Solves wrong gift card redemption | No | No |
Household is useful. It just does not solve this problem.
Can you share your Amazon account so someone else can use the balance?
Technically, someone with your login could use the balance. Practically, this is a bad idea.
Sharing your Amazon login exposes:
- saved payment cards,
- home addresses,
- order history,
- gift card balance,
- Prime membership,
- subscriptions,
- Kindle library,
- Audible account,
- Prime Video activity,
- returns,
- personal recommendations,
- security settings.
It can also create fraud flags, accidental purchases, privacy issues, and relationship drama. If the person buys something you did not approve, you may struggle to reverse it. If they change settings or address details, future orders may go wrong.
A safer option is to ask what they want and buy it for them from your account. You keep control of the account and balance.
What about family members, kids, or teens?
If the balance sits on a child’s, teen’s, spouse’s, parent’s, or old family account, the no-transfer rule still matters.
For children or teens, use parental controls and supervised shopping features where available. For spouses or partners, decide which account should redeem future gift cards before redeeming. For elderly parents, help them spend the balance on needed items rather than trying to move it.
If a minor redeemed a card to the wrong account, contact Amazon support quickly. But again, the standard policy is that redeemed balances cannot move between accounts.
What if someone sent the gift card to the wrong email?
This depends on whether the card has been redeemed.
If the digital gift card was sent to the wrong email but not redeemed, the buyer may be able to resend it or ask Amazon support for help, depending on the order and marketplace. If the wrong recipient redeemed it, recovery becomes much harder.
If you bought the gift card, check the gift card order details. Look for resend, cancel, or customer service options. Do not share new codes with anyone until you confirm the first one is safe.
If the intended recipient never received the card, check spam folders, email spelling, delivery status, and the gift card order page.
What if a scammer redeemed your Amazon gift card?
Act fast. Contact Amazon support immediately with the claim code, receipt, amount, purchase location, and redemption details if you have them. If you bought the card in a physical store, keep the activation receipt. If you received it digitally, keep the email.
Scammers often pressure victims to buy Amazon gift cards and share the code. No legitimate business, government agency, bank, tech support agent, police department, delivery company, or employer should demand payment through Amazon gift cards.
If you shared a code with a scammer and they redeemed it, the balance may be gone. Amazon may investigate, but recovery is not guaranteed. Report the scam to Amazon and the relevant consumer protection or law enforcement agency in your country.
Scam warning table
| Scam line | What it really means |
|---|---|
| “Pay your tax bill with Amazon gift cards” | Scam |
| “Your Amazon account is locked; send gift card codes” | Scam |
| “Buy gift cards to fix a bank issue” | Scam |
| “Your boss needs gift cards urgently” | Often scam |
| “Send codes to receive a prize” | Scam |
| “We can transfer your Amazon balance for a fee” | Likely scam |
| “We exchange Amazon balance for cash instantly” | High-risk or scam |
| “Share your login so we can move the balance” | Scam/security risk |
Amazon balance transfer services are not a real official solution.
Best legitimate workarounds
Since the direct transfer is not allowed, use one of these safer alternatives.
Workaround 1: buy the item for the other person
Ask them what they want, buy it from your Amazon account, and ship it to their address. This is the simplest replacement for a balance transfer.
Workaround 2: use their Wish List
If they have an Amazon Wish List, buy items from it using your balance. This works well for birthdays, baby gifts, dorm supplies, teacher lists, or household needs.
Workaround 3: spend the balance on shared needs
If you live together, use the balance for groceries, toiletries, pet supplies, cleaning products, school supplies, or household basics. Then settle money outside Amazon if needed.
Workaround 4: keep the old account for balance purchases only
If the balance sits on an old account, use that account only until the balance is gone. Then stop using it.
Workaround 5: contact support for honest mistakes
If you redeemed to the wrong account and did not spend the balance, contact Amazon support immediately. Do not expect a transfer, but ask for a review.
Workaround 6: buy a new gift card correctly next time
For future gifts, send an unredeemed card to the right person and remind them to redeem it on the correct marketplace and account.
Deep dive: what to do if you have balance split across two accounts
Split balance is annoying, but it is manageable if you stop trying to force a transfer and treat each account as a separate wallet.
Start by checking both balances. Write down the exact amounts and marketplaces. For example:
- Account A: $38.17 on Amazon.com.
- Account B: $64.00 on Amazon.com.
- Account C: £20 on Amazon.co.uk.
Do not mix countries in your plan. Amazon.com balance and Amazon.co.uk balance solve different shopping needs.
Next, decide what each account should buy. Use the smaller balance for everyday items: toiletries, batteries, books, pet supplies, phone cables, school supplies, kitchen basics, or a partial payment on a larger order. Use the larger balance for higher-value purchases.
If you need one expensive item, buy it from the account with the largest balance and pay the difference with a card. Then use the smaller balance for separate purchases. This is usually better than wasting hours trying to merge balances.
If both accounts are yours and one is old, spend the old balance first. Remove saved cards afterward if you do not want future purchases there. Once the balance is gone and all returns/refunds are complete, then decide whether to keep or close the account.
If the balance belongs to a family member, buy items they need from that account or ask them to use the balance for shared purchases.
This is the realistic answer to can you transfer Amazon gift card balance to another account when your goal is combining money. You cannot combine the balances directly, but you can plan purchases around each account.
How to avoid redeeming Amazon gift cards to the wrong account
Most gift card balance problems start with one small mistake: redeeming while logged into the wrong account.
Before redeeming, check:
- account email,
- country marketplace,
- household member profile,
- work vs personal account,
- mobile app account,
- browser account,
- old saved login,
- VPN/location confusion,
- gift card currency.
If you share a device, log out and back in. If you have multiple Amazon accounts, use different profile photos, browser profiles, or password manager labels. If you use Amazon in multiple countries, double-check the domain before redeeming.
Prevention checklist
| Before redeeming | Why |
|---|---|
| Check email address in account settings | Confirms correct account |
| Check Amazon domain | Prevents country mismatch |
| Confirm gift card country | Amazon.com card belongs on Amazon.com |
| Avoid shared devices | Reduces wrong-login mistakes |
| Do not redeem from email preview too fast | Check account first |
| Save receipt | Helps if redemption issue happens |
| Do not scratch physical code until ready | Reduces theft risk |
| Do not share claim code in chat | Codes can be stolen instantly |
| Redeem only when ready to use | Keeps gift flexible before redemption |
A gift card is flexible until redeemed. After redemption, flexibility drops sharply.
What not to do
Do not pay anyone who claims they can transfer Amazon balance.
Do not share your Amazon password with a stranger or “support agent.”
Do not buy another gift card expecting Amazon balance to pay for it.
Do not try to sell your balance on sketchy marketplaces.
Do not redeem gift cards while logged into a shared or old account.
Do not assume the same email across Amazon marketplaces means one shared balance.
Do not close an account with unused gift card balance.
Do not send gift card claim codes to anyone who pressures you.
Do not use gift cards to pay fines, taxes, fees, tech support, refunds, shipping releases, or account unlocks.
Practical scenarios
A shopper redeems a $50 gift card to their old Amazon account. They cannot transfer it to the new account. The best move is to buy items from the old account until the balance is gone, or contact support immediately if it was a genuine mistake and unused.
A parent wants to move a child’s $25 Amazon balance to their own account. Amazon will not provide a transfer button. The child’s account can buy an eligible item, or the parent can help use the balance safely.
A person in the U.S. buys an Amazon.com gift card for a friend in the UK. The friend cannot use it on Amazon.co.uk. The buyer should have purchased an Amazon UK gift card instead.
A couple has $40 balance on one account and $80 on another. They cannot combine balances for one $120 order. They can buy separate items or use the $80 account for the main order and pay the difference with a card.
A scammer claims they can “cash out” Amazon balance for 90% value. The user should avoid it. Official Amazon balance cannot be withdrawn to cash, PayPal, or bank transfer.

Conclusion
So, can you transfer Amazon gift card balance to another account? No. Once the claim code has been redeemed, Amazon generally locks that balance to the account where it was applied. You cannot move it to another Amazon account, combine it with another account’s balance, cash it out, or transfer it to another country’s Amazon site.
The best workaround is practical, not technical. Use the balance on the original account. Buy items for the person you wanted to help. Ship gifts to their address. Spend old-account balance before closing the account. If you redeemed a card to the wrong account by mistake, contact Amazon support quickly, but keep expectations realistic.
For next time, pause before redeeming. Check the account, check the marketplace, then apply the claim code. That small step prevents a very annoying balance problem.
