Maryland Area Codes Pieces Of Information

The state of Maryland is home to a variety of different area codes. These area codes are assigned to specific geographical areas within the state and are used to route telephone calls accordingly. The most populous city in Maryland, Baltimore, is served by three different area codes: 410, 443, and 667. The suburbs surrounding Baltimore also have their unique area codes. Montgomery and Prince George’s counties each have their code, while the rest of the state is served by a single code.

When making a call within Maryland, the caller must always use the correct area code for the location they are trying to reach. Failure to do so may result in the call not being able to go through or being routed to an incorrect location. For example, a call placed to 410-123-4567 from a location outside of the Baltimore area will not go through.

When making a long-distance call to Maryland from another state, the caller will need to use the correct area code for the location they are trying to reach. In addition, they will also need to dial 1 + the 10-digit phone number. For example, a call placed from New York to Baltimore would be dialed as 1-410-123-4567.

Lastly, it is important to note that some telephone numbers in Maryland may require the use of an additional digit after the area code when placing a call. This is known as an “access code” and is typically used for numbers that are toll-free or have special calling features. The most common access codes in Maryland are 888, 900, and 976.
