If an unfamiliar phone number appears on your Amazon account, it can signal a profile error, outdated contact data, or unauthorized access.
This guide explains how to remove unknown phone numbers from Amazon and tighten your account security at the same time.
Why an Unknown Phone Number on Amazon Matters
Amazon uses phone numbers for account verification, password resets, delivery updates, two-step verification, and fraud alerts.
If a number you do not recognize is attached to your account, it may interfere with sign-in recovery and can expose you to account takeover risks.
An unknown number does not always mean your account has been hacked.
It can also come from an old profile entry, a household account setup, a seller account update, or a stale number saved in your browser or mobile app.
First, Check Where the Number Appears
Before changing anything, identify whether the unknown number is stored in your Amazon login profile, address book, or security settings.
The removal process depends on where Amazon is using that number.
- Account settings: Phone number on your Amazon account profile.
- Login and security: Number used for verification or two-step authentication.
- Delivery address: Phone number saved with shipping information.
- Alexa, Kindle, or marketplace settings: A device or service profile connected to Amazon.
How to Remove Unknown Phone Number from Amazon Account Settings
The most common fix is editing your account information directly from Amazon’s website or app.
On the Amazon website
- Sign in to your Amazon account.
- Go to Account & Lists and select Your Account.
- Open Login & security or Your Addresses, depending on where the number appears.
- Select Edit next to the phone number field.
- Delete the unknown number and enter your correct phone number.
- Save the changes.
In the Amazon mobile app
- Open the app and sign in.
- Tap the menu icon and go to Your Account.
- Choose Account settings or Login & security.
- Edit the phone number, remove the unknown entry, and save.
If Amazon prompts you to verify the change, complete the code challenge sent to your email or current trusted number.
How to Remove an Unknown Number from Amazon Two-Step Verification
If the unknown number is connected to two-step verification, remove it immediately and replace it with a phone number you control.
This is especially important because two-step verification protects sign-ins and password changes.
To update it, open your Login & security settings, find Two-Step Verification, and review the registered phone number.
If Amazon lists a number you do not recognize, select the option to edit or disable it, then set up verification again with your own number or an authenticator app if available.
Using an authenticator app is often more secure than SMS because it reduces the risk of SIM swap attacks and text-message interception.
How to Remove a Phone Number from Shipping Addresses
Sometimes the unknown number is attached to a saved delivery address rather than the main account profile.
That number may appear during checkout, address editing, or order tracking.
- Go to Your Addresses.
- Select the address linked to the unknown number.
- Choose Edit.
- Delete the phone number field or replace it with your own.
- Save the updated address.
If the address is shared with another household member, check whether they added the number intentionally.
Shared Amazon households and gift recipients sometimes create confusion when multiple contacts are stored.
What to Do If You Cannot Change the Number
Sometimes Amazon will not allow you to remove the phone number because it is tied to account recovery or active verification settings.
In that case, use these steps:
- Update your password first: A strong new password can reduce the chance of unauthorized changes.
- Review recent sign-in activity: Look for unfamiliar devices, browser sessions, or location warnings.
- Check your email for Amazon alerts: Security notifications often explain why a change was blocked.
- Try a different browser or device: App cache or browser issues can prevent settings from saving.
- Contact Amazon support: Ask them to review the account phone number and remove any number you did not add.
When speaking with support, be ready to confirm your identity with your email address, order history, billing information, or backup verification method.
How to Tell Whether Your Amazon Account Was Compromised
An unknown phone number can be a sign of account compromise, especially if you notice other suspicious changes.
Watch for these indicators:
- Orders you did not place.
- Changed email address, password, or shipping address.
- Unrecognized sign-in alerts from Amazon.
- New devices added to your account.
- Gift card purchases or saved payment methods you did not approve.
If any of these appear, secure the account right away by changing the password, signing out of other sessions if possible, and reviewing payment methods and digital purchases.
Security Steps to Take After Removing the Number
Once you remove the unknown phone number from Amazon, lock down the account so the issue does not return.
Change your password
Create a unique password that you do not use elsewhere.
Avoid reused passwords because credential stuffing attacks often target shopping accounts with leaked login data.
Review account recovery options
Make sure your email address, phone number, and backup methods are current.
Remove any recovery details that belong to someone else or that you no longer control.
Enable stronger verification
If Amazon offers an authenticator-based verification option in your region or account type, consider switching from SMS to an app-based method.
Check payment methods and addresses
Confirm that all cards, bank accounts, and saved addresses belong to you.
Remove unfamiliar entries and monitor statements for unauthorized charges.
Common Reasons an Unknown Number Shows Up
Understanding the source can help you avoid the problem in the future.
Common causes include:
- A previous owner of the phone number is still tied to your account profile.
- You used a temporary number during signup or recovery and forgot to replace it.
- A family member added their contact details to your shared device or address.
- A mobile carrier reassigned an old number that was once linked to another person.
- Someone else accessed your account and changed the phone number.
When to Contact Amazon Support
Contact Amazon support if the unknown number keeps returning, if you cannot edit the field, or if you suspect unauthorized access.
Support can verify the account, investigate security changes, and help you regain control of your profile.
Use Amazon’s official help channels inside your account or on the Amazon Help page rather than responding to emails or texts that ask for verification codes.
Never share one-time passwords, even if the message claims to be from Amazon.
