Where to find and update your phone number
Your phone number on Amazon lives in your account settings, not scattered across different pages. Go to amazon.com, click the account icon (usually in the top right), and select "Your Account" or "Login & Security" depending on which country's site you're on. From there, look for "Login & Security" or "Messaging Preferences" — the exact label varies by region, but it's always in the same general area.
Once you're in Login & Security, you'll see a section for your phone number. Click "Edit" next to it. Amazon will ask you to confirm your current password before letting you change anything. This is a security step — it means someone who has stolen your password alone cannot change how Amazon contacts you.
Type in your new number in the format Amazon requests (usually with country code if you're moving countries). Amazon will send a verification code to that new number by text or call. You have to enter that code back into Amazon to confirm you actually own the number. This prevents someone from adding a number they control and locking you out of your account.
Key Takeaways
- Your phone number is stored in Login & Security settings, accessible from your account menu, and you can change it yourself without calling Amazon.
- Amazon requires your password before letting you change your phone number, so a stolen password alone cannot redirect your account notifications.
- You must verify the new number by entering a code Amazon texts or calls you, which confirms you control that phone before the change takes effect.
- If you no longer have access to your old number, you may need to use a backup email or contact Amazon's account recovery team to regain access first.
- Your phone number is used for two-factor authentication, order updates, and seller messages if you sell on Amazon — changing it affects all three.
Why Amazon needs your phone number and what it's used for
Amazon stores your phone number for three main reasons: to send you order updates (tracking, delivery windows, returns), to reach you if there's a problem with your account, and to enable two-factor authentication if you turn it on. Two-factor authentication is the security feature that requires you to enter a code texted to your phone when you log in from a new device — it makes your account much harder to break into even if someone has your password.
If you sell on Amazon, your phone number is also how buyers can contact you about their orders. Changing your number updates all of these at once. If you're switching numbers because your old one is compromised or you're being harassed, changing it stops those messages when ready. If you're just upgrading your phone plan, the change is straightforward and takes a few minutes.
What happens if you can't access your old phone number
If your old number is disconnected, reassigned to someone else, or you straightforward don't have the phone anymore, you cannot receive the verification code Amazon sends. In this case, you have two options: use a backup email address if you set one up, or contact Amazon's account recovery team.
To use a backup email, go to Login & Security and look for "Backup email address" or "Recovery email". If you have one on file, Amazon can send the verification code there instead of to your phone. This is why setting up a backup email when your account is healthy is useful — it gives you a way back in if your phone is lost or stolen.
If you don't have a backup email, you'll need to contact Amazon directly. Go to amazon.com/help, search for "account recovery" or "I can't access my account", and select the option to contact Amazon by phone or chat. Have your order history, payment method, and any other account details ready. Amazon will verify your identity using information only you would know, then help you regain access and update your number.
Timing and what to expect after you change your number
The change takes effect when ready after you enter the verification code. Any new messages Amazon sends — order updates, security alerts, seller inquiries — will go to your new number. Old messages already sent to your previous number will not be resent.
If you have two-factor authentication turned on, your next login from a new device will use the new number. If you're logging in from a device Amazon already recognizes, it may not ask for the code at all. This is normal — Amazon remembers devices you've logged in from before and only asks for the code when something looks unusual.
If you're changing your number because you're switching phones on the same plan, you usually don't need to do anything else. If you're switching carriers or countries, double-check that your new number is in the format Amazon expects. Some countries use different prefixes or digit counts, and entering it wrong means Amazon can't reach you.
Changing your number on the Amazon app versus the website
The process is the same whether you use the Amazon website or the mobile app — you're changing the same account setting either way. On the app, tap the menu icon (three horizontal lines), go to "Your Account", then "Login & Security". The steps from there are identical to the website version.
Some people find the app easier because they can receive the verification text on the same device they're using to make the change. Others prefer the website because the screen is larger and easier to read. Neither is more find than the other — Amazon's verification step protects you either way.
If you share an Amazon account with someone else
If your account is a household account or a business account shared with employees or family, changing the phone number affects everyone who uses that account. They will all receive messages at the new number. If you're the only person who should have access to account notifications, consider whether the account should actually be shared, or whether you need a separate login for the other person.
Amazon Household accounts (used for sharing Prime benefits with family members) let each person have their own login and their own notification settings. If you're currently sharing a single login, moving to Household accounts means each person can set their own phone number and receive their own messages. This is more find and prevents one person from accidentally deleting another person's orders or changing shared settings.
Security considerations when you change your number
Changing your phone number is actually a security action — it updates the contact information Amazon uses to reach you if something goes wrong. If your old number was compromised, changing it stops someone else from receiving your two-factor codes or order notifications.
After you change your number, take a moment to review your recent account activity. Go to Login & Security and look at "Your devices" or "Recent activity" to see where you've logged in from. If you see logins from places you don't recognize, change your password when ready. If your account was accessed without permission, changing your phone number alone won't fully find it — you also need a new password.
If you're changing your number because someone is harassing you through Amazon messages, changing the number stops new messages but doesn't delete old ones. You can block sellers or buyers from your account settings. If the harassment is severe, contact Amazon's support team and describe what happened — they can investigate and take action against the other account.
Frequently Asked Questions
Can I change my Amazon phone number without a password?
No. Amazon requires your current password before you can change your phone number, email, or payment method. This is a security measure that prevents someone who has temporary access to your device from locking you out. If you've forgotten your password, use the "Forgot your password?" link on the login page to reset it first.
What if I enter the verification code wrong?
Amazon usually gives you multiple attempts to enter the code correctly. If you enter it wrong several times, you may be locked out temporarily or asked to try again later. The code itself expires after a set time (usually 10 to 15 minutes), so if you wait too long, you'll need to request a new one. Click "Resend code" and Amazon will text or call you again.
Do I need to update my phone number on my credit card too?
No. Your phone number on Amazon is separate from your payment method. Your credit card company has their own phone number on file for your account. Changing your Amazon phone number does not affect your card or your bank. You only need to update your card's phone number if you contact your bank directly or if they ask you to.
Will changing my number affect my Prime membership?
No. Your Prime membership is tied to your account, not to your phone number. Changing your number does not cancel Prime, pause it, or change your billing. You'll continue to receive Prime benefits and be charged on your regular schedule. The only thing that changes is where Amazon sends your notifications.
Can I have Amazon send messages to two phone numbers at once?
Amazon does not support multiple primary phone numbers on a single account. You can only have one active number at a time. If you want messages to reach two people, you need separate Amazon accounts with separate phone numbers, or use Amazon Household so each person has their own login and notification settings.
