Change your phone number in Account Settings

Go to amazon.com and sign in. In the top right corner, hover over "Account & Lists" and click "Account". On the left side, click "Login & security". You'll see your current phone number listed under "Phone number". Click "Edit" next to it.

Amazon will ask you to confirm your identity before letting you change the number. You may be asked to enter a code sent to your current phone number, or to answer security questions you set up when you created your account. Once verified, enter your new phone number in the field provided and click "Save changes".

The change takes effect immediately. Amazon will not send a confirmation email or text — the number updates in your account right away. If you're changing the number because you no longer have access to your old phone, the verification step becomes harder, which is covered below.

Key Takeaways

  • You change your phone number through Account Settings under "Login & security", not through a separate phone or payment section.
  • Amazon requires you to verify your identity before changing the number, usually by entering a code sent to your current phone.
  • If you can't access your old phone number, you'll need to answer security questions or contact Amazon's support team for help.
  • Your new number is used for two-factor authentication codes and order delivery notifications, so updating it prevents login problems later.

What happens if you can't access your old phone number

If you've already switched phones and no longer have the old number, the verification step will block you. Amazon will offer you the option to answer security questions instead — these are questions you set up when you created your account, like "What is your mother's maiden name?" or "What was the name of your first pet?"

If you don't remember the answers to your security questions, or if you never set them up, you'll need to contact Amazon directly. Go to amazon.com/contact-us, select "Account & Login Issues", then "I can't sign in to my account" or "I need help with my account security". Amazon's support team can verify your identity through other means — usually by checking your purchase history, email address, or payment method on file — and then change the number for you.

This process typically takes a few hours to a day. During that time, you won't be able to use two-factor authentication to sign in, so keep your password secure and avoid signing in on shared devices.

Why Amazon asks for your phone number

Your phone number serves two main purposes on Amazon. First, it's used for two-factor authentication — when you sign in from a new device or location, Amazon sends a code to your phone to confirm it's really you. Second, delivery drivers use it to contact you if they can't find your address or need to drop off your package in a specific spot.

If your phone number is outdated, you might not receive delivery notifications or two-factor codes, which can lock you out of your account. Updating it ensures you stay connected to your orders and can sign in without trouble.

Changing the phone number linked to your payment method

Your Amazon account phone number and your payment method phone number are separate. If you want to update the phone number on a credit card or debit card, that's handled differently. Go to "Account & Lists" and click "Your Account", then select "Manage payment methods" or "Your payments".

Find the card you want to update and click "Edit". You can change the billing address and contact information associated with that card. This is important if your card issuer uses your phone number to contact you about fraud alerts or payment issues — updating it there won't change your Amazon account phone number, and vice versa.

Updating your phone number on a business or Prime account

If you have an Amazon Business account, the process is the same: go to Account Settings and click "Login & security". Business accounts use the same phone number for both account access and business order notifications.

For Amazon Prime members, changing your phone number doesn't affect your Prime membership or benefits — it only updates how Amazon contacts you about deliveries and account security. Your Prime status stays active regardless of what phone number is on file.

What to do if you see an unfamiliar phone number on your account

If you log into your account and see a phone number you don't recognize, someone may have gained access to your account. Change your password immediately by going to "Account & Lists" > "Account" > "Login & security" > "Password". Then update your phone number to one you control.

Check your recent orders and payment methods to see if anything looks wrong. If you see unauthorized purchases or unfamiliar payment methods, contact Amazon support right away. You can also enable two-factor authentication to make it harder for someone else to sign in, even if they have your password.

Frequently Asked Questions

How long does it take for Amazon to update my phone number?

The change happens instantly once you save it. You can use your new number for two-factor authentication codes and delivery notifications right away. If you contacted Amazon support to change it, the update may take a few hours.

Will changing my phone number affect my Amazon Prime membership?

No. Your Prime membership is tied to your email address and account, not your phone number. Updating your phone number won't cancel your membership or change any of your benefits.

Can I use a landline or Google Voice number instead of a cell phone?

Amazon accepts most phone numbers, including landlines and Google Voice numbers. However, if you use a landline, you won't receive two-factor authentication codes via text, so you'll need to use a backup method like your email address to sign in from new devices.

What if I change my number but forget to update Amazon?

You'll have trouble signing in on new devices because Amazon won't be able to send you the two-factor code. When you try to sign in, you can choose to verify your identity using security questions or your email address instead, but it's easier to update the number ahead of time.

Do I need to update my phone number on the Amazon app and the website?

No. Your phone number is stored in your Amazon account, not on individual devices or apps. Changing it once updates it everywhere — the website, the mobile app, and any other way you access your account.
