History of Area Code 227
Area code 227 entered service on March 24, 2022, as an overlay for area codes 240 and 301. It was not created through a geographic split, so existing 240 and 301 customers kept their phone numbers while new numbers could receive the 227 code.
Area code 301 was one of the original North American area codes created in 1947 and initially covered all of Maryland. Area code 410 split from 301 in 1991 to serve eastern Maryland, and area code 240 overlaid 301 in 1997. Area code 227 added more numbering capacity to the existing 240 and 301 region.
