Where is the 667 Area code?

It covers major areas such as Baltimore, Columbia, Towson, Dundalk, Parkville, and Essex, as well as surrounding locations across Baltimore County, Anne Arundel County, Harford County, and Howard County.
The 667 area code was added as an overlay to the existing 410 and 443 area codes to provide additional numbering capacity for the region’s growing population and businesses. Today, all three area codes serve the same geographic area, making 667 an important part of the wider Baltimore area’s communication network.

History of 667 area code
The 667 phone area code is a significant part of Maryland’s telecommunications landscape, covering Baltimore and the surrounding cities. Established in 2012, the 667 number overlays the same geographic location served by 410 and 443.
The decision to implement 667 as an overlay was driven by the rapid increase in cell phones in the 1990s and 2000s, which resulted in the shortage of available numbers in the 410 region. In July 1997, area code 443 was introduced as an overlay to 410 to address the demand.
However, this area code also started to fall short due to the rapid population growth. Hence, to relieve the pressure on the 443 area code, on March 24, 2012, area code 667 was put into service for the first time.
