Here's Something Worth Knowing
Just because you see 301 on your caller ID doesn't guarantee the person is actually sitting in Maryland right now. Since 2003, people can take their phone numbers with them when they move.

That said, a 301 number usually means the person originally got their phone number somewhere in Maryland. Or they specifically chose a 301 number for business reasons - maybe to seem local to customers in the Rockville area.
How to Dial a 301 Number
If you're calling from somewhere else in the country, just dial 1 + 301 + the 7-digit number. Calling from overseas? Use your country's exit code (usually 00 or +), then 1 for the US, then 301 and the rest.
