How to Change Your Phone Number on Amazon
Keeping your contact information current on Amazon isn't just a housekeeping task — your phone number is tied to account security, two-step verification, delivery notifications, and carrier-based authentication. If your number has changed, or you want to swap out an old one, Amazon does give you a straightforward path to update it. But where you go and what you update depends on what that phone number is actually doing on your account.
Why Your Phone Number Matters on Amazon
Amazon uses phone numbers in a few distinct ways, and it's worth understanding the difference before you start clicking through settings:
- Account contact number — used for order-related SMS alerts, delivery updates, and general account communication
- Two-Step Verification (2SV) — a security layer that sends a one-time code to your phone when you sign in from an unrecognized device
- Amazon Pay or billing verification — some payment flows use a registered phone for identity confirmation
These aren't always the same number, and updating one doesn't automatically update the others. That's a common source of confusion when people think they've changed their number but keep receiving texts on the old one.
How to Change Your Primary Phone Number on Amazon 📱
On a Desktop Browser
- Go to Amazon.com and sign in
- Hover over "Account & Lists" in the top right corner
- Click "Account"
- Under the "Login & security" section, click "Edit" next to your mobile number
- Enter your new number, then verify it with a one-time code Amazon sends via SMS
- Save your changes
Amazon requires verification before the update goes through — so you'll need access to the new number at the time you make the change.
On the Amazon Mobile App
- Tap the profile icon (bottom navigation bar)
- Go to "Your Account"
- Tap "Login & security"
- Find the phone number field and tap "Edit"
- Follow the same verification steps as above
The process is nearly identical across iOS and Android versions of the app, though the exact layout may vary slightly depending on your app version.
Updating Your Two-Step Verification Phone Number
If you use a phone number as your two-step verification method, that's managed separately from your general account number.
- Go to "Account & Lists" → "Account"
- Click "Login & security"
- Find "Two-Step Verification (2SV) Settings" and click "Edit"
- You can add a new phone number as an authenticator, set it as primary, and remove the old one
Important: Don't remove the old number until the new one is confirmed and working. If you lock yourself out during this process, account recovery becomes significantly more complicated.
It's also worth noting that Amazon supports authenticator apps (like Google Authenticator or Authy) as an alternative to SMS codes. If you're changing your number because you're concerned about SIM-swap attacks or SMS reliability, switching to an authenticator app at this stage is a meaningful security upgrade.
What Happens to Delivery Notifications?
Amazon delivery notifications — the "your package is out for delivery" texts — are typically sent to the phone number associated with your account. Once you update your primary number, future notifications should route to the new one. However:
- Orders already in transit may still send updates to the number on file at the time of purchase
- Third-party sellers on Amazon may have cached your old number in their own systems
- Amazon Flex or delivery partner notifications sometimes operate on slightly different data sync timelines
Don't be alarmed if a delivery text still goes to your old number for an active shipment — that's a timing issue, not a settings error.
Variables That Affect the Process
Not every user hits the same experience when updating their phone number. A few factors that can change what you encounter:
| Variable | How It Affects the Update |
|---|---|
| Account age / history | Older accounts with more purchase history may trigger additional identity verification |
| Active 2SV setup | If 2SV is enabled via phone, you may need to verify both the old and new numbers |
| Region / country | Phone number formats and verification SMS delivery vary by region |
| Business vs. personal account | Amazon Business accounts have additional admin settings that may affect contact info |
| Recent account changes | If you've recently updated your password or email, Amazon may add extra friction as a fraud prevention measure |
If You've Already Lost Access to the Old Number
This is where things get more complicated. If your old number is no longer active and it's currently set as your two-step verification method, you may not be able to sign in at all — because Amazon will try to send a code to a number that no longer works.
In this case:
- Use a backup verification method if you set one up (a backup phone number, authenticator app, or backup codes)
- If no backup exists, you'll need to go through Amazon's account recovery process, which involves identity verification and may take several days
- Contact Amazon Customer Service directly — they have an account recovery pathway, but expect to provide proof of identity
This is a strong argument for setting up a secondary verification method before you ever need to change your primary number. ⚠️
The Detail That Changes Everything
Knowing the steps is straightforward — but what makes this update simple or complicated depends entirely on your current account configuration. Whether you have 2SV enabled, what method you're using for it, whether you still have access to the old number, and whether you're on a personal or business account all determine how many steps are actually in front of you.
The mechanics are the same for most users. The friction, if any, lives in the specifics of how your account is currently set up.
