Area code 667 is an all-services overlay of 410 and 443, so it covers the same eastern Maryland area, from the Baltimore metropolitan area to all of the Eastern Shore, as the numbering administrator puts it.
The Washington suburbs and western Maryland use 301 and 240.

From the public records of the body that runs US phone numbering, read October 21, 2026.
The Maryland Public Service Commission approved the 667 overlay on January 3, 2001, so no one had to change a number. It entered service on March 24, 2012, over the same area that already had 410 and 443.
Ten-digit dialing was already required when 667 arrived, so every local call needs the area code, whether the number starts with 667, 410 or 443.
