What Does *77 Do on Your Phone?

If you've ever wondered what happens when you dial *77 on your landline, it’s actually a handy feature designed to keep unwanted anonymous calls at bay. This simple code activates a service known as Anonymous Call Rejection.

When you dial *77 and enable the feature, your phone will automatically block incoming calls from people who hide their number using caller ID blocking. Instead of your phone ringing and potentially disturbing your day, the caller on the other end hears a message: “The party you are calling does not accept blocked calls.” Essentially, their call never reaches you.

This service is especially useful if you're tired of getting calls from unknown or telemarketing numbers that show up as "Private," "Blocked," or "Unknown." It adds a layer of privacy and control, letting you decide who can reach you—and who can't.

Activating it is simple: just lift the receiver and dial *77. To turn it off later, you can usually dial *76. Keep in mind that availability of this feature may vary depending on your phone service provider and region, and it’s typically designed for traditional landlines rather than mobile phones.

While *77 is a straightforward solution, it’s not foolproof—some scammers may still get through using spoofed numbers. Still, it remains a reliable tool for minimizing nuisance calls. If peace and privacy matter to you, it’s worth trying. Just remember to check with your provider to confirm it’s supported on your line.
