History of the 240 Area Code

Before the 240 area code existed, the 301 area code handled all phone numbers in this part of Maryland. As more people started using cell phones, fax machines, and internet services, the number of available phone numbers became limited.

To solve this issue, the 240 area code was introduced in 1997. Instead of replacing the existing 301 area code, it was added as an overlay. This means both area codes serve the same geographic region.

Today, new phone numbers in the region may receive either a 240 or a 301 area code.
