Will *67 work if I'm blocked?

Can *67 Bypass a Block?

Short answer: sometimes, but not reliably.

You’ve probably heard that dialing *67 before a number hides your caller ID, making your call show up as “Private,” “Unknown,” or “No Caller ID.” That part is true—and it’s a handy trick if you’re trying to reach someone who might not want to see your number. But does it work if they’ve already blocked you?

The reality is more complicated. While *67 can help you avoid being recognized by caller ID, it won’t always bypass a true block. If someone has actively blocked your number, their carrier or phone settings may reject the call entirely—regardless of whether your ID is hidden. In some cases, the call might go through, especially if the block only stops calls with visible numbers, but don’t count on it.

Here’s how it works: in the U.S. and Canada, simply dial *67, then the number (like *67 555-123-4567), and your call will temporarily mask your identity. It’s a quick, legal method—and it still works on most carriers. But keep in mind, it’s not a loophole. Many modern smartphones and services use advanced filtering that can flag or send hidden-number calls straight to voicemail.

And ethically? If someone blocked you, there’s usually a reason. Trying to circumvent that can come across as intrusive. It’s worth asking yourself whether the call is truly necessary.

So yes, *67 can help hide your number—and in rare cases, it might let a call through. But it’s far from a guaranteed fix, and it’s not meant to override someone’s boundaries.
