How to Change Your Phone Number on Amazon

Updating your phone number on Amazon is one of those account maintenance tasks that sounds simple but has a few layers worth understanding — especially if you use your number for two-step verification, order notifications, or Amazon Pay. Here's exactly how it works, what to watch out for, and why your specific setup affects how straightforward the process actually is.

Why Your Phone Number Matters on Amazon

Amazon ties your phone number to several different account functions, and that's where many people get tripped up. It's not just a contact detail sitting in your profile — it can also be your two-step verification (2SV) method, your delivery notification channel, and in some cases the backup authentication path for your account.

If you only update it in one place, you may find it's still active — or worse, missing — in another. Understanding what's connected to your number before you change it saves a lot of frustration.

How to Change Your Phone Number on Amazon 📱

On a Desktop Browser

1. Go to amazon.com and sign in
2. Hover over "Account & Lists" in the top right, then click "Account"
3. Under "Login & security", click "Edit" next to your mobile number
4. Enter your new number and follow the verification prompts
5. Amazon will send a one-time password (OTP) to confirm the new number

This is the primary location for your account phone number and the one most directly tied to login security.

On the Amazon Mobile App

1. Tap the person icon (bottom navigation bar) to open your account
2. Tap "Account", then scroll to "Login & security"
3. Select your phone number and tap "Edit"
4. Enter and verify your new number via OTP

The app process mirrors the desktop flow — both update the same underlying account record.

Two-Step Verification: The Part People Miss ⚠️

If you've enabled two-step verification (2SV) on your Amazon account, your phone number may be registered there separately as an authentication method. Changing your number in Login & Security doesn't automatically update your 2SV settings.

To check and update this:

1. Go to Login & security
2. Scroll to Two-Step Verification (2SV) Settings and click Edit
3. Review whether your old number is listed as an authenticator method
4. Add your new number and remove the old one

Skipping this step can lock you out of your account if you ever need to verify a login and the OTP gets sent to a number you no longer own.

Other Places Your Number May Appear

Amazon's ecosystem has multiple touchpoints where phone numbers can live independently:

Not every Amazon user has all of these active, but it's worth scanning the list against your own usage.

What Affects How Smooth This Process Is

Several variables determine whether updating your number is a five-minute task or a more involved process:

Whether your old number is still accessible. If you still receive texts on your old number, the transition is clean — Amazon will verify the change using an OTP. If you've already lost access to the old number, the process gets more complicated. You may need to verify your identity through email or contact Amazon customer support directly, which can take longer and require additional proof of ownership.

Whether 2SV is enabled and which method you're using. Users with two-step verification active via SMS are more exposed to a phone number change than those using an authenticator app (like Google Authenticator or Authy). If your 2SV runs through an authenticator app, the phone number change in Login & Security is lower risk — your login verification path isn't phone-dependent.

Whether you use Amazon Pay or Amazon Business. These platforms sometimes maintain their own contact records that aren't automatically synced with your main Amazon account. Users with Amazon Pay enabled should specifically check those settings, as payment verification flows can still reference an outdated number.

Your device ecosystem. If you have Alexa-enabled devices and use Amazon's calling and messaging features, your phone number is registered separately in the Alexa app under communication settings. Users who rely on Alexa for household calls should update this independently.

If You've Already Lost Access to Your Old Number

This is the scenario that creates real friction. Without access to the old number, you can't receive the OTP needed to confirm changes through the standard flow. Your options generally include:

• Using an alternative verification method — if your account has email-based 2SV or a backup code, you may be able to authenticate that way
• Contacting Amazon customer support — be prepared to verify your identity with order history, billing information, or account credentials
• Account recovery flow — Amazon's account recovery process exists for situations like this, though it requires patience and accurate account information

The earlier you catch a number change need — ideally before you lose access to the old number — the easier the process is.

The Variables That Define Your Situation

The core steps for changing a phone number on Amazon are consistent, but the actual experience varies significantly based on whether you have 2SV active and which method you're using, whether you still have access to the old number, how many Amazon services you're tied into (Pay, Business, Alexa), and whether your number is registered across multiple regional Amazon accounts.

Someone with a straightforward consumer account and no 2SV can complete this in under three minutes. Someone with 2SV enabled via SMS, an Amazon Pay account, and Alexa calling set up may need to update their number in three or four separate locations — and the order in which they do it matters.

Your own account configuration is the piece that determines which parts of this process apply to you.
