How Annapolis came to have 3 area codes
The original Annapolis area code is 410, in service since 1991. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 443 (1997) and 667 (2012). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Annapolis now uses all 3 codes and every local call is dialed with ten digits.
