How to change Apple ID trusted phone number
If you need to update the phone number Apple uses for account verification, the process is straightforward once you know where to look.
This guide explains how to change Apple ID trusted phone number on iPhone, iPad, Mac, and the web, plus what to do if you no longer have access to the old number.
What a trusted phone number does
A trusted phone number is the number Apple uses to send verification codes for two-factor authentication.
It helps you sign in to your Apple ID, reset your password, and confirm account activity on devices such as iPhone, iPad, Mac, Apple Watch, and the web.
Apple recommends keeping at least one trusted number that you can access at all times.
You can also add more than one number, which is useful if you switch carriers, travel often, or rely on a backup SIM or family phone.
Before you change the trusted number
Before updating your Apple ID phone number, check these basics to avoid interruptions:
- Make sure you can sign in with your Apple ID on a trusted device.
- Confirm the new number can receive SMS texts or phone calls.
- Have your current device passcode ready, since Apple may require it.
- Verify that two-factor authentication is already enabled on your account.
If you are replacing your old number completely, keep access to it until the new one is confirmed.
That reduces the risk of getting locked out during the update.
How to change Apple ID trusted phone number on iPhone or iPad?
The fastest way is through the Settings app on a trusted iPhone or iPad.
- Open Settings.
- Tap your name at the top to open Apple Account settings.
- Tap Sign-In & Security.
- Tap Two-Factor Authentication or Trusted Phone Numbers, depending on your iOS version.
- Tap Edit or Add a Trusted Phone Number.
- Enter the new phone number and choose whether it should be verified by text message or phone call.
- Enter the verification code sent to that number.
- Remove the old number if you no longer use it.
On newer versions of iOS, the Apple Account interface may appear slightly different, but the path still leads through your account security settings.
If the old number is still listed, deleting it after the new one is verified helps keep your account up to date.
How to change Apple ID trusted phone number on Mac?
You can also update trusted numbers from a Mac signed in to the same Apple ID.
- Open System Settings.
- Select your Apple Account name at the top of the sidebar.
- Click Sign-In & Security.
- Find Trusted Phone Numbers or the two-factor authentication section.
- Click Add or Edit.
- Enter the new number and verify it with the code Apple sends.
- Remove the old number if needed.
On older macOS versions, the same controls may appear under System Preferences and Apple ID.
The steps are similar, but the menu names can vary by release.
How to change it on the web?
If you do not want to use a device, you can manage Apple ID security at Apple’s account website.
- Go to account.apple.com.
- Sign in with your Apple ID.
- Open the Sign-In and Security section.
- Locate trusted phone numbers or two-factor authentication settings.
- Add the new number and verify it.
- Delete any outdated number you no longer control.
This method is helpful if you are setting up a new phone number after a carrier change, but you may still need a trusted device or verification code to complete the sign-in.
How do you replace an old trusted number?
If your goal is to fully switch from one number to another, add the new number first, confirm it works, and then remove the old one.
That order matters because Apple generally wants at least one active trusted number tied to your account.
When the new number is verified, test it by signing in on a device or requesting an account code.
If the code arrives correctly, you can safely delete the old number from your trusted list.
What if you no longer have the old number?
Losing access to the old trusted number does not always block the change, but it can make account recovery harder.
If you still have access to a trusted Apple device, you can usually update the number from Settings or System Settings.
If you cannot sign in and the old number is unavailable, use Apple’s account recovery process.
Apple may ask for additional verification, such as a device passcode, recovery contact help, or waiting for recovery to finish.
Avoid creating a new Apple ID unless you have exhausted recovery options, since that can separate your purchases, iCloud data, and subscriptions.
Common issues when changing a trusted phone number
Several common problems can slow the update:
- Verification code not arriving: Check cellular service, spam filters, and whether the number can receive SMS.
- Old number still receiving codes: Remove it after adding and confirming the new one.
- Account sign-in prompts repeat: Make sure you are using a trusted device signed in with the same Apple ID.
- Carrier issues: VoIP and some business numbers may not work reliably for verification.
- Region or SIM changes: If you switched countries or phone plans, confirm the new number is active and able to receive messages.
If a code still does not arrive, try requesting a phone call instead of text.
Apple sometimes offers both options, and one may work better depending on your carrier settings.
How to keep your Apple ID secure after the change
After updating your trusted phone number, review your account security settings to keep everything consistent.
- Check that your trusted devices are current.
- Review recovery contacts if you have set them up.
- Make sure your email address and phone number are both active.
- Use a strong, unique password for your Apple ID.
- Keep at least one backup trusted number if possible.
These steps matter because Apple ID access affects iCloud Photos, iCloud Drive, Find My, App Store purchases, Apple Music, and device activation.
A current trusted number helps protect all of them.
When to update your trusted phone number
It is a good idea to change your Apple ID trusted phone number whenever you:
- Switch carriers or get a new mobile plan
- Replace an old SIM or phone number
- Lose access to your previous number
- Move to a different country or region
- Share a number that will soon be disconnected
Updating it early prevents verification failures later, especially when you are resetting a password, signing in on a new device, or approving an unfamiliar login.
