Dial `*67` before the number you are calling
If `*67` does not work, contact your mobile carrier in Jamaica for the correct caller ID blocking code
Go to your phone settings and turn on caller ID blocking for outgoing calls
Use a caller ID blocking option from your phone app, if available
Ask your carrier to activate permanent caller ID suppression on your line
Use a third-party calling app that supports hidden caller ID, if permitted by your carrier
Check whether the person you are calling allows blocked or private numbers to go through
