How to Protect Your Phone Number on iOS: A Comprehensive Guide

Protecting your phone number on your iOS device is essential for maintaining privacy and reducing unwanted solicitations. Apple offers several built-in features to help you manage your caller ID and block spam calls. Additionally, third-party applications like Robokiller provide enhanced protection against unwanted calls.

How Can I Hide My Caller ID on iOS?

Apple allows you to hide your caller ID for all outgoing calls through your iPhone's settings:

1. Open the Settings app.
2. Scroll down and tap on Phone.
3. Select Show My Caller ID.
4. Toggle off Show My Caller ID.

When this setting is disabled, your number will appear as "No Caller ID" or "Private" to the recipient. Note that some carriers may not support this feature, and the option might be unavailable or grayed out. (support.apple.com)

How Can I Temporarily Hide My Caller ID for a Single Call?

For one-time anonymous calls, you can use a carrier-specific code:

1. Open the Phone app.
2. Dial *67 followed by the phone number you wish to call.
3. Press Call.

For example, to call 555-123-4567 anonymously, dial *675551234567. This method works on most U.S. carriers and hides your number for that specific call only. (simplymac.com)
