The Maryland Public Service Commission (PSC) announced Wednesday the assignment of 227 as a new area code which will eventually serve the same geographic area in Maryland that is currently served by the 240 and 301 area codes. If you have a 240/301 area code number, that will not change. Counties that currently use the 240/301 area code include Allegany, Charles, Garrett, Montgomery, Prince George’s, St. Mary’s, and Washington counties.

The addition of the ‘227’ code is due to the dwindling supply of existing 240/301 phone numbers. According to the PSC, “the remaining supply of available telephone numbers in the 240/301 area is estimated to be exhausted in the second quarter of 2023 – requiring the establishment of a new area code to support future demands in the region. Customers with a 240 or 301 area code will maintain their existing area codes and their phone numbers will not change. Under the implementation plan approved by the PSC, no new 227 numbers will be assigned in the area until the remaining 240/301 numbers are completely exhausted.”
According to a press release, the PSC voted on August 3, 2022, to approve a petition filed by the North American Numbering Plan Administrator (NANPA), which is the neutral third-party entity that allocates telephone numbering resources.
