source checks
Source group made visible
Area code records use the `nanpa-area-code-resources` source group. NANPA remains the primary reference for public area-code lookup and NPA planning reports.
source and asset policy
Representative points only
Area code records are a manually reviewed launch seed checked against NANPA/NANP area-code resources and representative metro coordinates.
USGuess does not use telecom boundary polygons, carrier databases, customer address data, phone-number ownership data, or copied official maps as quiz material.
