What to do if a 661 number called you

  1. Do not call back and do not press any key to "opt out".
  2. Never give codes, card numbers or remote access to an inbound caller.
  3. Block the number and report the call at reportfraud.ftc.gov.
  4. Report it to GACS so other people searching this number find your warning — report a scam call.

Questions people ask

Is every call from a 661 number a scam?

No. Area code 661 is a normal US area code used by ordinary businesses and people. The numbers listed here are the ones consumers named in Do Not Call complaints — the area code itself tells you nothing about whether a specific call is legitimate.

Why do I keep getting calls from 661 numbers?

Scam dialers often spoof a local-looking prefix so the call appears familiar, and they rotate through numbers within the same area code. That is why blocking one number rarely stops the calls.

Should I call a 661 number back?

No. Returning a call to an unknown number can confirm your line is live or connect you to a premium-rate service. A genuine caller will leave a voicemail.

Where do these counts come from?

The US Federal Trade Commission publishes the phone numbers named in Do Not Call complaints as daily open-data files. GACS aggregates those files. These totals cover only the days we have processed, not all time.

Source: FTC Do Not Call complaint data. Complaints are unverified consumer allegations and caller ID is easily spoofed, so a listed number may belong to someone unconnected to the calls.
