About the 301 area code
The Baltimore region of Maryland uses area code 301, together with Germantown, Silver Spring, Rockville, and Bethesda. Eastern time governs the whole territory.
One of the original codes assigned in 1947, 301 later saw 410 split away while 240 was placed on top of it. It now anchors an overlay complex with 240 and 227, where ten-digit local dialing is the rule.
Dialing note: 301 is part of an overlay complex with 240, 227, so local calls in this area are dialed with all ten digits.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
