To call with a private number, you can use several methods depending on whether you want to hide your number temporarily for a single call or permanently for all outgoing calls.

Temporary Private Call (Single Call)

• Dial *67 before entering the phone number you want to call. This will block your caller ID for that call only, showing up as "Private," "Blocked," or "Anonymous" on the recipient's phone

Example: If you want to call (123) 456-7890, dial *67 123 456 7890.

• Note: This method does not work for toll-free numbers or emergency services like 911

Permanent Private Call (All Calls)

• On Android phones, you can hide your number for all outgoing calls by changing the caller ID settings:
  1. Open the Phone app.
  2. Tap the menu (three dots) and go to Settings.
  3. Select Calls or Call settings.
  4. Find Caller ID or Additional settings.
  5. Choose "Hide number" or "Never" to block your number on all calls

• Alternatively, contact your mobile carrier and ask them to enable permanent caller ID blocking on your account

Using Prefix Codes by Country

• Different countries use different prefix codes to block caller ID temporarily. For example:
  • North America: *67 or #31#
  • India: #31# or *31#
  • UK/Ireland: 141
  • Germany: *31# or #31#

Dial the prefix code before the phone number to hide your caller ID for that call.

Additional Options

• Use third-party apps like Burner, Hushed, or Dingtone to create temporary numbers and manage caller ID privacy

• Use Google Voice to make calls from a different number, masking your real number
