What to do if a 645 number called you
- Do not call back and do not press any key to "opt out".
- Never give codes, card numbers or remote access to an inbound caller.
- Block the number and report the call at reportfraud.ftc.gov.
- 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 645 number a scam?
No. Area code 645 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 645 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 645 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.
