How Brighton came to have 3 area codes
The original Brighton area code is 303, in service since 1947. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 720 (1998) and 983 (2022). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Brighton now uses all 3 codes and every local call is dialed with ten digits.
