To change your phone number on a Samsung account, you need to update it inside your account’s two-step verification settings, not as a standalone phone number field. Samsung uses your phone number for two-step verification and account recovery, so keeping it current protects your account security.
Why change your phone number on a Samsung account
Samsung requires a phone number for two-step verification and account recovery. If you get a new number or switch carriers, updating it ensures you can still receive verification codes and recover your account if you forget your password. Keeping your number current also prevents unauthorized access and keeps your account secure.
How to change your phone number on a Samsung phone
On a Samsung phone, open Settings and tap Accounts and backup. Then tap Manage accounts and select Samsung Account. Tap My profile, then Security and privacy, and then Two-step verification. Enter your Samsung Account password when prompted. Under Verification methods, tap Text message, then tap Add. Enter your new phone number, tap Send code, enter the code you receive, and tap Verify.
Samsung Australia documents a slightly different on-device path: open Settings, tap your Samsung Account profile name, select Profile info, then tap Phone number and verify your Samsung Account password. Tap Add, type the new number, select Send code, enter the code, and tap Verify.
How to change your phone number on a computer
On a computer, go to the Samsung account sign-in page and sign in with your credentials. Open Security or Password and security depending on the region. Select Two-step verification, then Text message. Select Edit personal information or Add phone number, enter the new number, select Send code, enter the verification code, and select Verify.
Verifying the new phone number
Samsung sends a verification code by SMS to the new number. Enter that code in the space provided and tap Verify to confirm the number. This step is documented consistently across Samsung’s US, UK, and Australian support pages.
Removing the old phone number
Samsung Australia documents removing the old number from the Phone number section after adding and verifying the new one. Go back to the phone number settings, find the old number, and select the option to remove or delete it. Confirm the removal so the old number is no longer associated with your account.
What to do if you can’t receive the verification code
If you cannot receive the verification code because you are locked out or the number is unreachable, Samsung documents a separate recovery flow. Follow the account recovery process on the Samsung account sign-in page. If that does not work, contact Samsung support for help regaining access to your account.
Frequently Asked Questions
Will changing my phone number affect my existing data on my Samsung account?
No. Changing your phone number does not affect any of your existing data, saved settings, or preferences. Only the phone number associated with your account is updated.
Why do the menu labels differ by region?
Samsung’s support pages show slightly different menu names depending on the region and device software version. For example, the UK path uses “Accounts and backup” while Australia uses “Profile info.” The core steps, adding, verifying, and removing a number, remain the same.
Do I need the old phone number to change it?
In most cases you need access to the old number only if you are logged in and can verify your identity with your password. If you are locked out and cannot receive codes on the old number, use Samsung’s account recovery process or contact support.
Can I revert back to my old phone number after changing it?
Yes, you can add the old number again as a new number if you still have access to it and can receive the verification code. However, you will need to go through the same add-and-verify process.
Does changing your phone number affect how I check if my phone is linked to another device?
No. Changing your phone number does not affect device linking or the ability to check if my phone is linked to another device. Device linking is managed separately in your Samsung Account settings under connected devices.
What about updating phone number on apps and other accounts?
Changing your Samsung Account phone number only updates it for Samsung services. You will need to separately update the number for any other apps or accounts that use it, such as Google or carrier services. This is part of the broader process of updating phone number on apps and accounts.
How do I remove old phone numbers from accounts after adding a new one?
After adding and verifying the new number, go back to the phone number section in your Samsung Account settings, locate the old number, and select remove or delete. This is the standard process for removing phone numbers from accounts and devices.
