Find any 410- phone number in Maryland

The 410 area code is an area code within the North American Numbering Plan (NANP). This system designates specific three-digit area codes for use in a specific geographical area or geographic region. This area code covers the entire state of Maryland, an area that includes both suburbs and rural areas, as well as large cities such as Baltimore and Annapolis.

The 410 area code was first introduced in 1947, when an area code expansion split the old 301 area code into two distinct sections, one becoming the 410 area code. This meant that telephone customers in Maryland no longer had to dial a full ten-digit number, and could instead simply dial the three-digit area code and the seven-digit phone number. This was a revolutionary move at the time, and made it easier for people to remember and dial phone numbers. Today the 410 area code and the North American Numbering Plan are still the standard for telephone services in the United States and Canada.
