Caller ID is a common telephone service that allows you to see the caller’s phone number before answering the call. Conversely, when you make a call to someone, your caller ID will also appear on other’s phone.

For whatever reason you want to hide your caller ID from appearing on the callee’s phone, you can use one of the following methods to disable the caller ID feature.

Temporarily Block Caller ID

Generally, mobile operators offer special code for you to block your call ID on call-by-call basis. In case you just want to hide your caller ID for an individual outbound call, you can dial the special code prior to the number you’re calling to enable the blocking. Say, you’re in U.S. and want to dial 212-323-3322. In North America, you can use the special code *67 to disable caller ID. So instead dialing the number directly, dial *67-212-323-3322. This will prevent your caller ID from appearing and your callee will just see a “Blocked” call.

However, the special code varies by countries. According to Wikipedia, you can use the following special code to disable caller ID:

  • Argentina: *31*
  • Australia: 1831
  • Denmark and Switzerland: *31*
  • Germany: *31# (for some mobile providers may use #31#)
  • Hong Kong: 133
  • Israel: *43
  • Italy: #31# (most cell phone companies)
  • New Zealand: 0197 (Telecom) and *67 (Vodafone)
  • North America: *67
  • United Kingdom and Ireland: 141
  • Sweden #31#

Permanently Block Caller ID on iPhone

If you plan to block your caller ID for all calls, you can to go to “Settings” -> “Phone” -> “Show My Caller ID”. Simply disable the caller ID feature by turning the switch to OFF.

For now, when you make any call, your callee cannot view your caller ID and usually the number will be appeared as “Blocked” in other’s phone.
