How Sugar Land came to have 5 area codes

The original Sugar Land area code is 713, in service since 1947. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 281 (1996), 832 (1999), 346 (2014) and 621 (2025). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Sugar Land now uses all 5 codes and every local call is dialed with ten digits.
