About this app

Block annoying scammers who hide behind fake phone numbers.

Do you get unwanted calls from phone numbers similar to your own? This is known as caller ID neighbor spoofing, and it's a common trick to try to get you to pick up the phone. Blocking these calls can be difficult because the number isn't always the same.

With Number Shield, you can block an entire group of numbers at once. Just enter a wildcard for each digit you want to block.

For example, if your phone number is 714-555-1234, scammers might call you using a number like 714-555-6789. You can block all similar numbers by entering 714-555-####. Wildcards and numbers can be combined in any order you choose.

Please note:

• Blocked calls are sent directly to voice mail.
• Number Shield does not block text messages.

More information about caller ID spoofing in the United States is available from the FCC:

I've been using this on my android since January 2020. Does exactly what is advertised. Stopped my robo call experiences. Does not consume phone's battery life (and if it does it's negligible), and if a number you are blocking calls you, the phone will start ringing/vibrating for about 1/4 of a second while the app activates and rejects the call/sends it to voicemail. Also removes the "missed call" notification. Best dollar I ever spent.

This simple app works great for neighbor spoof calls. I used it for about 3 years on my iPhone and recently switched to android. The neighbor spoof calls to my number immediately came back in at a rate of about ten per day until I found Number Shield on Google Play. Now everything is quiet again. I don't trust negative ratings with no review - anyone who can't take a minute to explain their issue probably didn't take the time to set the app up properly.

Super simple! Honestly I just added my area code and that has cut the robo callers by at least 90%. A few other area codes get in, but just add them to the block list. I went from 5 robo calls a day to maybe 1 every other week, as I add more area codes, the calls get less and less frequent. Enable it to see your contacts and they will not be blocked by the area codes. Forgot to add, I've been using this app now for half a year. And I'm super happy with it!
