How do I change the phone number on a Samsung account?
Answer
Sign in at the official Samsung account website or on a signed-in Galaxy phone, open Security or Personal info settings, and update the phone number after verifying the current methods.
Follow these steps
Sign in on an official Samsung page or device
Open the official Samsung account website or Settings > Accounts on a Galaxy phone that is still signed in.
You should see: You reach the Samsung account profile or security screens.
Update the phone number
Open Personal info or Security settings, select the phone number field, enter the new number, and confirm the SMS code.
You should see: The Samsung account shows the updated phone number.
Use account recovery if you cannot sign in
If access is fully blocked, start Samsung's official Find email or Reset password recovery using the account email and any remaining verification methods.
You should see: Access is restored enough to change the phone number, or Samsung lists what proof is still required.
Review remaining security methods
After the number changes, confirm backup email and two-step verification settings still look correct.
You should see: The account has a working phone number and at least one backup recovery method.

Extra tips
What to look for: Whether any Samsung device or browser session is still signed in, and whether recovery is available through email
Before you change anything: Confirm the Samsung account email address. Have the new phone nearby to receive SMS verification. Use only the official Samsung account site or phone settings. Never share Samsung verification codes with unexpected callers.
