About the 443 area code
Since 1997, Baltimore, Maryland has had 443 among its area codes. The code stretches to Columbia, Ellicott City, Glen Burnie, and Annapolis, and its numbers follow the Eastern clock.

Dialing note: 443 is part of an overlay complex with 410, 667, so local calls in this area are dialed with all ten digits.
