443 Area Code in Maryland, United States

Description

Area code 443 is an overlay of 410 in eastern Maryland, including Baltimore, Columbia, Towson, and parts of the Eastern Shore. It was introduced in 1997 to accommodate the demand for new numbers in the fast-growing Baltimore metro area. In 2012, 667 was also added as a second overlay. Ten-digit dialing is mandatory throughout the region. While 410 remains the legacy code, 443 is now commonly assigned to mobile phones and newer residents. It plays a vital role in maintaining connectivity in one of the state's most populous and economically significant regions. 443 is a staple of Maryland’s evolving telecommunications landscape.
