Feature Answer

What is Area Code 410?

Area code 410 is a North American telephone area code assigned to Baltimore, covering Baltimore, Towson, Annapolis. It was created in 1991 when area code 301 was split to handle growing demand. The code is local rather than toll-free, and it operates on Eastern Time.

Before 1991, Baltimore was part of the larger 301 footprint. As the region grew, the FCC carved out 410 to serve its own community, leaving 301 to anchor a more focused area. Today 410 is the recognized code for Baltimore, used across local businesses, institutions, and households.
