Find any 667- phone number in Maryland
The 667 area code is designated for use in Maryland, USA, as part of the North American Numbering Plan (NANP). The NANP is a system of numbering designed to make it easier for phone companies and users to route calls between different countries, states, provinces, and regions.
The 667 area code divides the state of Maryland into different regions. It is focused in Baltimore City and its surrounding cities, such as Dundalk, Towson, and Middle River. There are also smaller areas in Centreville, Bel Air, Randallstown, and Reisterstown that use the 667 area code. All of these areas have been assigned the 667 area code since 1999. The state of Maryland started using the North American Numbering Plan in 1947, primarily for the purpose of making out-of-state calls easier to connect. Currently, the 667 area code is one of the largest area codes in the state, covering many cities and counties in the east and central parts of the state.
