There’s no definitive way to know if someone has blocked your phone number—you won’t be notified—but there are some clues to look for that may suggest it’s happened.

First, if your calls always go straight to voicemail or only ring once before going to voicemail, it could be a sign of being blocked. A typical call will ring more than once. However, the recipient may have simply turned off their phone or put it in Do Not Disturb mode.

You can also try to leave a message and see if they get back to you. If your number has been blocked, they won’t receive the voicemail. Again, this is not a surefire way to know if you’ve been blocked. They may just be slow to respond.

For better or worse, you’ll have to figure it out on your own or ask friends and family to do reconnaissance for you. If you suspect you’ve been blocked, it’s best to respect their wishes.
