Change your phone number in Account Settings
The fastest way to update your phone number is through your Amazon account settings on a computer or phone. Sign in to your Amazon account, go to Account & Lists in the top right, then select Your Account. From there, click Login & security on the left side. You will see a section called Phone number with your current number listed.
Click the Edit button next to your phone number. Amazon will ask you to confirm your identity — usually by sending a code to your current phone number or email address. Enter that code when prompted. Then type in your new phone number, choose whether it is a mobile or landline, and click Save changes. The update takes effect immediately.
If you no longer have access to your old phone number, you can use your email address to verify instead. Select the email option when Amazon asks how you want to confirm your identity, and the verification code will arrive in your inbox.
Key Takeaways

- The new phone number becomes active immediately after you save the change.
- If you cannot access your old phone number, use your email address for verification instead.
- Your phone number is used for account recovery, two-factor authentication, and order notifications — updating it keeps your account secure.
Why Amazon needs your phone number
Amazon stores your phone number for account security and communication. The number is used to send you verification codes if you sign in from a new device, to contact you about orders, and to help you recover your account if you forget your password. Some Amazon services, like Prime Video or Alexa, may also use it for account recovery or notifications.
Keeping your phone number current matters because an outdated number means you might not receive important security alerts or order updates. If someone else gains access to your account, you may not get the warning code in time to stop them.
Changing your number on the Amazon app
The process on the mobile app is nearly identical to the website. Open the Amazon app, tap the menu icon (three horizontal lines) at the bottom right, then tap Your Account. Scroll down and select Login & security. Find Phone number and tap Edit.
Amazon will send a verification code to your current phone or email. Enter it, type your new number, and tap Save. The change syncs across all your devices within minutes.
What to do if you cannot verify your old number
If your old phone number no longer works or you no longer have access to it, you have two paths forward. First, try using your email address for verification instead — this is the simplest option and works in most cases. Amazon will send the verification code to your registered email rather than your phone.
If you cannot access your email either, or if Amazon will not let you proceed, you will need to contact Amazon Customer Service. Go to Help & Customer Service on the Amazon website, select Contact Us, and choose the option for account and login issues. Explain that you cannot verify your identity through your phone or email, and a representative can help you update your number after confirming your identity through other means, such as your name, address, and recent order history.
Two-factor authentication and your phone number
If you have turned on two-factor authentication for your Amazon account, your phone number becomes even more important. This security feature sends a code to your phone every time you sign in from a new device. If your phone number is outdated, you will be locked out of your account when you try to sign in elsewhere.
After you update your phone number, two-factor authentication automatically uses the new number for future sign-ins. You do not need to turn it off and back on. If you are having trouble signing in after changing your number, wait a few minutes for the change to sync, then try again.
Removing your phone number entirely
You can remove your phone number from your Amazon account, though Amazon recommends against it for security reasons. To do this, go to Account & Lists > Your Account > Login & security > Phone number, click Edit, and delete the number from the field. Click Save changes.
Without a phone number on file, you will not receive text message notifications about orders or account activity. You also will not be able to use your phone for two-factor authentication or account recovery. If you forget your password, recovering your account becomes more difficult. Most people keep a phone number on their account for these reasons.
Frequently Asked Questions
How long does it take for my new phone number to work?
The change is instant. As soon as you click Save, your new number is active on your account. If you are trying to sign in with two-factor authentication, you may need to wait a minute or two for the system to sync across Amazon's servers, but this is rare.
Will changing my phone number affect my Prime membership or orders?
No. Your Prime membership, order history, and payment methods remain unchanged. Only the phone number associated with your account is updated. You may start receiving order notifications at your new number instead of your old one.
What if I enter the wrong phone number by mistake?
You can change it again immediately using the same process. Go back to Login & security, click Edit next to your phone number, and enter the correct one. Amazon will ask you to verify your identity again before saving the change.
Can I use an international phone number?
Yes. When you enter your phone number, you can select your country from the dropdown menu. Amazon accepts phone numbers from most countries, though some features like text message notifications may not work with all international numbers. Enter the number with the country code included.
Do I need to update my phone number on other Amazon services like Alexa?
No. Alexa and other Amazon services use the phone number from your main Amazon account automatically. Once you update it in Account Settings, all connected services see the new number. You do not need to change it separately anywhere else.
