Winning customers in Charm City

Baltimore rewards businesses that feel rooted in its neighbourhoods.

From Fells Point and Canton to Federal Hill, Hampden and Mount Vernon, the city is a patchwork of places with strong local loyalty. Healthcare and research, port logistics, government contracting and a lively restaurant scene all keep the phones busy. A Baltimore number helps you get picked up by people who screen out unfamiliar callers.

Three codes, one Baltimore

410, 443 and 667 are layered on top of each other, not divided by district.

410 is the long established code and the one many Marylanders still think of first. 443 and 667 were added as overlays to supply more numbers, so a new line is often issued on one of them. All three are equally local in Baltimore, Annapolis and on the Eastern Shore, so pick the one you like from whatever is available.

Every call, captured and routed

Allo adds a team and an assistant behind your Maryland number.

Calls go to the right teammate, and when nobody is free the AI receptionist answers, gathers the details and books a time. Recordings, transcripts and AI summaries are saved automatically and sync to HubSpot, Salesforce or Pipedrive. Customers can text the same number, your team can work from any device, and switching over is as easy as porting your current line.

Baltimore phone numbers, answered

Baltimore uses 410, 443 and 667. They overlay the same area, which stretches to Annapolis and Salisbury. 410 started in 1991, 443 in 1997 and 667 in 2012, all on Eastern time.

You choose from the Baltimore numbers available at signup, which can span 410, 443 and 667. For a particular number, ask the Allo team to look for it.

No. Nothing about a Baltimore number requires you to be in Maryland. Your team can answer it from anywhere on the Allo apps.

Yes. 667 is an overlay on the same area as 410 and 443, so it is just as local to Baltimore callers. It is simply the newest of the three, added in 2012.
