On an iPhone, “private number” usually means your caller ID is hidden for outgoing calls. To remove it, you mainly need to turn caller ID back on in Settings and, in some cases, adjust a carrier code or reset network settings.

Quick Scoop

1. Check your iPhone Caller ID setting

This is the most common fix and works on most carriers.

  1. Open Settings on your iPhone.
  1. Scroll down and tap Phone.
  1. Tap Show My Caller ID.
  1. Turn the switch ON (it should be green). If it was off, this was forcing “Private Number” on all outgoing calls.
  1. Make a test call to someone and confirm your number now shows instead of “Private” or “Unknown.”

If this setting is missing or greyed out, your carrier may control caller ID at their end, so see the next steps.

2. Remove private number via carrier code (if used)

Some people accidentally enable private number using a code rather than the iPhone menu.

  • If you hid your number with a code like *31#, many carriers let you undo it with #31# (dial it like a normal call, then hang up).
  • After dialing the code, place a test call and see if your number now appears.

Not all carriers support this, so if nothing changes, move on to the next step.

3. Reset network settings (when the issue persists)

If the Caller ID toggle looks correct but calls still show as private, your network or carrier settings might be misconfigured. To reset network settings:

  1. Go to Settings → General.
  1. Tap Transfer or Reset iPhone.
  1. Tap Reset → Reset Network Settings.
  1. Enter your passcode and confirm.

This will reset Wi‑Fi, cellular, and VPN settings, which can fix caller ID restrictions that got stuck.

After the restart, check Show My Caller ID again and place a test call.

4. When nothing works: contact your carrier

If:

  • Show My Caller ID is missing or permanently greyed out, or
  • Your calls still show “Private Number” even after checking settings and resetting networks,

then your mobile carrier may be forcing caller ID blocking on your line.

Ask support to:

  • Confirm that outgoing caller ID is enabled on your account.
  • Remove any “permanent caller ID block” or “private number” feature attached to your number.

Once they lift the block, your number should start showing again.
