If you want to make calls without showing your number, your iPhone has a built-in feature that lets you hide your caller ID. Once enabled, your number will appear as “No Caller ID” or “Private Number” on the recipient’s phone.
This guide walks you through how to block your caller ID step by step.
Why Block Caller ID?
Hiding your number can be useful when you:
- Want to protect your privacy
- Are calling someone for the first time
- Prefer not to share your personal number
- Need temporary anonymity
How to Block Caller ID on iPhone
Follow these simple steps:
Step 1: Open Settings
Tap the Settings app on your iPhone home screen.
Step 2: Go to Phone Settings
Scroll down and tap Phone.
This section controls your call-related features.
Step 3: Tap “Show My Caller ID”
Find and tap Show My Caller ID.
Step 4: Turn Off Caller ID
Toggle the switch off.
- On (green): Your number is visible
- Off (gray): Your number is hidden
Step 5: Test It
Make a call to a friend or another phone to confirm your number appears as No Caller ID.
What Happens After You Turn It Off?
Once disabled:
- Your number is hidden on outgoing calls
- Recipients will see “No Caller ID” or similar
- Your incoming calls are not affected
How to Hide Caller ID for One Call Only
If you don’t want to disable caller ID permanently, you can hide it for a single call by dialing:
*67 + phone number
Example: *67 08012345678
This works on many carriers but may vary by region.
