FAQ · Maryland virtual numbers
Common questions about Maryland virtual phone numbers.
Quick answers on Maryland's 5 area codes, DC suburb vs Baltimore codes, ET routing, and porting your existing MD number.
Maryland has five active area codes: 240 (DC suburbs overlay — Montgomery and Frederick counties), 301 (DC suburbs — Bethesda, Silver Spring, Rockville), 410 (Baltimore metro — Baltimore, Annapolis, Columbia), 443 (Baltimore metro overlay), and 667 (Baltimore overlay). All five are on Ringflow.
301 is the code for the DC suburbs — primarily Montgomery County (Bethesda, Rockville, Silver Spring, Germantown) and Prince George's County. 410 is Baltimore's primary code, covering the city, Annapolis, Columbia, Towson, and the surrounding Baltimore metro. They represent Maryland's two distinct major economic corridors.
301 and 240 are the codes for Montgomery County — home to NIH, FDA, NIST, and the concentration of federal agencies and biotech firms along the I-270 corridor. For businesses targeting the federal contracting and life-sciences market in Bethesda, Rockville, or Gaithersburg, 301 or 240 are the natural choices.
