Amazon handles gift cards differently from every other retailer covered here, and the difference matters. The balance lives on your account rather than on the card, and Amazon will not show you the value of a code you have not yet redeemed. There is no page anywhere that lets you peek at a card's value first, whether physical or eGift card.
Gift cards and codes
The balance is on your account, not the card.
On the web, Account & Lists then Gift cards shows your total and a Gift Card Activity log listing every code claimed and every order that drew on the balance. In the Amazon app, the account icon then Gift Card Balance does the same.
What you cannot do is check an unredeemed claim code. Amazon does not offer that, by design. Your options are to redeem it to an account and read the balance there, or ring customer service on 1-888-280-4331 and have them look it up. If you bought the card yourself, the code also sits in your order history. Anything else claiming to check an Amazon balance is not doing what it says.
Why that design matters for safety
Because there is no legitimate standalone checker, every site offering one is either useless or a phishing operation collecting claim codes. A claim code is bearer value — whoever redeems it first owns it, and there is no reversal.
That also makes Amazon the most common brand named in gift card payment scams. Anyone asking to be paid in Amazon codes, for any reason, is running one.
What we don't do
HelpMeLogin runs no Amazon service and has no login form. We cannot check a balance, redeem a code, or recover one that has been used. Amazon.com, Inc. operates from Seattle, Washington and its customer service is the only route to a balance figure without redeeming.
