Area code 443 is the overlay for the 410 code, covering the Baltimore metropolitan area and Maryland's Eastern Shore. The overlay was introduced in 1997 as demand for numbers in the rapidly growing Baltimore-Washington corridor outpaced 410's capacity. Both codes now require 10-digit dialing throughout the coverage area.
Across मैरीलैंड, the 443 area code serves roughly 2 million residents in 4 communities — including Baltimore, Annapolis, Columbia, among others. Numbers in the 443 zone keep Easterntime, so a local line rings during your customers' business hours and shows a familiar एमडी caller ID on every outbound call.
443 was first introduced in 1997 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.
