Area code 227

Area code 227 serves Maryland, including Washington Zone 10, Washington Zone 02 and Myersville (Eastern time). It has been in service since June 14, 2023 and shares its area with 240 and 301.

Numbers starting with 227 drew 349 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 133 complaints to the FCC since November 2023. The number on your screen can be faked, so a 227 number proves nothing about where a call came from.

Phone companies holding 227 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 100% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
