Call Blocker helps you block spam calls and look up suspicious phone numbers. Check community reports about unwanted telemarketing calls and potential phone scams, and choose which calls to block.
PROTECT YOURSELF FROM SPAM CALLS
Block calls from numbers identified as spam by UnknownPhone.com and its community. Update the spam number list in the app to include newly identified numbers and block their calls automatically.
CHECK SUSPICIOUS PHONE NUMBERS
Look up a number and read available information and community reports before calling back. Results depend on the information contributed by the community; not every number will have a result.

• Block numbers that start with a specific prefix or sequence of digits.
• Block calls from numbers that are not in your contacts.
• Block international calls from numbers that are not in your contacts.
• Block calls with a hidden number or no caller ID.
• Block individual numbers you add to your personal block list.
Enable the options that suit you and manage your blocked numbers in the app.
