Amazon Account Email Verification: OTP and Sign-In Codes

Updated October 13, 2026 · 5 min read

Amazon uses email in two different moments: once to confirm a brand-new account, and again whenever someone signs in from a device it does not recognize. The two messages look alike, six digits each, but they mean different things and need different handling. This guide explains both, what changes when you turn on 2-Step Verification, and what Amazon asks for that no email can answer.

The two codes Amazon emails

Both carry a 6-digit one-time code, both are single-use and short-lived, and when a new code is sent, only the newest one is valid. If you are looking at a code and are not sure which one it is, the subject line tells you.

Verifying a new account

On amazon.com, or your country's Amazon site, Create account asks for a name, an email and a password, then a click on "Verify email". Amazon sometimes shows an image puzzle at this point, and nothing is sent until it is solved. Once it is, the verification email goes out and you type the code into the page.

If the code does not appear:

• Check for the puzzle. A session left at the puzzle never sends anything.
• Check the address. A typo sends the code to someone else's inbox or nowhere.
• Resend once, then wait. Each resend makes the previous code useless, so resending repeatedly works against you.

Sign-in attempt codes on new devices

After the account exists, every sign-in from a phone, browser or TV that Amazon has not seen can trigger "Amazon: Sign-in attempt". This keeps going for the life of the account, so the address that receives it has to stay reachable.

Two practical rules follow:

• Sign in on your devices early. Doing it in the first session means the codes arrive while you are watching for them.
• Turn on 2-Step Verification. Amazon's Two-Step Verification sends its codes to a phone number or an authenticator app, which moves day-to-day sign-in security off the email inbox. Set it up with your own phone or app.

What Amazon asks for beyond email

The code confirms the address and nothing more. Several later steps depend on you alone:

• A phone number. Amazon now and then asks a new account for one after the email code. Use your own.
• Payment details. Amazon checks payments strictly. A card name or billing address that does not match the account, or frequent card changes, can put a new account on hold. Use a card in your own name with real details.
• A delivery address in your name before your first order.
• Seller Central is a separate process from a shopping account, with identity documents, a bank account and sometimes a video interview under Amazon's own rules.

Amazon's Conditions of Use apply throughout, including one buyer account per person and accurate information.

One login across Amazon storefronts and services

Most Amazon storefronts, such as .com, .co.uk, .de and .co.jp, share one login, so one verified account often works on several of them; check the site you plan to use, because policies can vary by marketplace. The same account also signs in to Prime, Kindle and Audible, and to Prime Video, covered in Prime Video sign-up with a separate email. Developers testing Login with Amazon, Alexa Skills or Amazon Pay often prefer a dedicated account for that work, apart from personal shopping.

A separate address for the first OTP

A rented inbox can take the first email step if you would rather not use your main address. Select Amazon on OTPGmail, take a real @gmail.com or @icloud.com inbox and paste it at Create account; the OTP appears on your order page, with no mailbox login involved. The 30-day figure for Amazon is 95% of orders with a code, and the typical wait is about 2 minutes. No code within the waiting time (25 minutes at most)? The order cancels itself with a 100% refund. Extra codes cost nothing within the order period when the service sends more than one; the limit and time window are shown before you rent. The Amazon rental page has the step-by-step.

Because sign-in attempt codes keep coming long after sign-up, move a long-term account to an address you own under Login & security once it is set up.

Frequently asked questions

Does "Amazon: Sign-in attempt" mean someone else is in my account?

Not by itself. Amazon sends it whenever a sign-in comes from a device it does not recognize, including your own new phone. If you did not just try to sign in, change your password.

Can I use an @icloud.com address for an Amazon account?

Yes. Amazon accepts @icloud.com the same way as @gmail.com. iCloud inboxes are usually cheaper than Gmail to rent, depending on the service.

Is there a refund if Amazon asks for a phone number after the code?

No. The email code was delivered, so the rental is complete; the phone step belongs to Amazon's process.
