Is area code 667 a scam?
No. Area code 667 is a legitimate area code serving Baltimore since 2012. Scammers spoof caller ID to display 667 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 667 number, and the number they display may belong to a real business in Baltimore that has nothing to do with the call.

Area codes that overlay 667
Area code 667 shares its geographic footprint with 2 other codes: 410, 443. Overlays are laid over an existing area rather than splitting it, so all local calls require the full ten-digit number.
Area code 667 has served Baltimore, Maryland, and the surrounding region since 2012, overlaying the older 410 and 443 codes. Baltimore's economy is anchored by medicine and logistics. Johns Hopkins University and its hospital system form the city's largest private employer, the University of Maryland Medical System follows close behind, and the Port of Baltimore moves more autos and roll-on cargo than any other US port. Under Armour is headquartered here, and federal agencies and defense contractors cluster nearby thanks to Washington's proximity.
Who lives in the 667 region
The city counted about 573,200 residents in 2024, with a median household income of $62,177, per DataUSA. Baltimore is a majority-Black city with strong neighborhood identities, and its metro workforce stretches deep into the suburbs, so a number in this territory reaches both rowhouse blocks and county office parks.
What a 667 number signals to a caller
Baltimore is on its third area code, which means residents have dialed ten digits for decades and treat new codes with little fuss. Still, 410 remains the code with the longest local memory, and callers describe a 667 number as reading newer, though it rings to the same streets. An outside caller should know that business culture here is more direct than Southern and less rushed than New York, and that area code 667 is fully local to Baltimore, Maryland, hospitals, port terminals, and all.
