When Does Star 67 Not Work?

When you dial emergency numbers 

Emergency numbers are essential to acquire valid caller information to respond promptly for help in emergency conditions.

Sometimes, other than dialing toll-free or emergency numbers, circumstances like blocked numbers prevent Star 67 from working. To elaborate, if someone blocks your number on their device, Star 67 will not prevent them from seeing your caller ID. 

Such a situation happens because the recipient’s block settings prioritize over any endeavors to hide your caller data.

In some cases, Star 67 does not work because of your phone service provider. You may find variations in phone service providers that handle caller ID blocking differently

The effectiveness of Star 67 in blocking caller ID depends on the phone service provider’s factors, such as phone settings, blocking services, and recipient contact lists.
