How do I add a phone to my Apple ID?

The process to associate a phone with your Apple ID depends on what you're trying to accomplish. Are you trying to add a trusted phone number for verification, associate a new iPhone with your Apple ID, or add a phone you manage through Apple Business Manager/Apple School Manager?

Here's a breakdown of common scenarios and how to address them:

1. Adding a Trusted Phone Number for Two-Factor Authentication

If you want to add a phone number to your Apple ID to receive verification codes for two-factor authentication, follow these steps:

1. On your iPhone, iPad, or iPod touch:

   • Go to Settings > [Your Name] > Password & Security.
   • Next to Trusted Phone Number, tap Edit.
   • Tap Add a Trusted Phone Number.
   • Enter the phone number and select whether you want to verify it with a text message or phone call.
   • Follow the on-screen instructions to verify the phone number.

2. On your Mac:

   • Choose Apple menu  > System Settings, then click [Your Name].
   • Click Password & Security.
   • Next to Trusted Phone Number, click Edit. You might be asked to enter the password for your Apple ID.
   • Click the Add button (+).
   • Enter the phone number and select whether you want to verify it with a text message or phone call.
   • Follow the on-screen instructions to verify the phone number.

A trusted phone number is used to verify your identity when you sign in on a new device or browser.

2. Signing in to a New iPhone with your Apple ID

When setting up a new iPhone, you'll be prompted to sign in with your Apple ID. This automatically associates the iPhone with your Apple ID.

1. During the setup process, when you reach the Apps & Data screen, select how you want to transfer your data (e.g., from iCloud Backup, another iPhone).
2. Continue following the on-screen instructions until you reach the Apple ID screen.
3. Enter your Apple ID (email address or phone number) and password.
4. You may be prompted to enter a verification code sent to your other devices or trusted phone number.
5. Once signed in, the iPhone is associated with your Apple ID.

3. Adding Devices in Apple Business Manager/Apple School Manager (for Managed Devices)

This method is used for businesses and schools to manage devices. It is not the same as simply associating a personal device with your personal Apple ID. These devices are typically supervised, meaning the organization has some level of control.

1. In the Profile Manager sidebar, select Users. (This assumes you're using Profile Manager).
2. Select a user, then click the Devices tab.
3. Click the Add button, then select Add Devices. A window appears showing all enrolled devices.
4. Select or search for the devices you want to associate with the user, then click Done.

This process is typically handled by an IT administrator or similar role within the organization.

If none of these scenarios match your intention, please provide more context about what you're trying to achieve when you say "add a phone to my Apple ID."
