Is area code 623 a scam?
No. Area code 623 is a legitimate area code serving Glendale since 1999. Scammers spoof caller ID to display 623 numbers, which is why complaints exist against a code that is itself genuine.
Neighbour spoofing is the reason a local-looking number is not a guarantee. A caller anywhere in the world can display a 623 number, and the number they display may belong to a real business in Glendale that has nothing to do with the call.
