Using #31# before dialing a number on an iPhone does not block your number. For a permanent solution, go to 'Settings' > 'Phone' > 'Show My Caller ID', and toggle it off. For a one-time block, dialing *67 before the number can temporarily hide your caller ID in the U.S. Check your carrier's specific method if located in another country.
