Area code 667 is a 2012 overlay serving the Baltimore metropolitan area and surrounding counties, supplementing the existing 410 and 443 codes. As Baltimore and its suburbs continued growing and adding mobile devices and IoT connections, a third overlay became necessary. All calls within the coverage area require 10-digit dialing.
Across Maryland, the 667 area code serves roughly 2 million residents in 4 communities — including Baltimore, Annapolis, Columbia, among others. Numbers in the 667 zone keep Easterntime, so a local line rings during your customers' business hours and shows a familiar MD caller ID on every outbound call.
667 was first introduced in 2012 as an overlay of the 410 area code, adding fresh numbering capacity to the same region without forcing anyone to change an existing number. Because an overlay shares geography with another code, ten-digit dialing is standard throughout the area. It remains an active overlay code today.
