source checks

Source group made visible

ZIP code records use the `us-census-zcta-gazetteer` source group. Census ZCTA/Gazetteer references support map-friendly learning points; USPS lookup stays a postal guardrail, not a copied boundary source.

Census ZCTA Guidance

Defines ZCTAs as Census geographic products used for mapping and analysis of ZIP code patterns.

Census Gazetteer Files

Public Census reference hub for national and state Gazetteer files, including ZIP/ZCTA-style geography files.

USPS ZIP Code Lookup

Postal lookup reference for address, city/state, and covered-city checks; not used as a boundary map source.

source and asset policy

Representative points only

ZIP code records are a manually reviewed launch seed checked against Census ZIP Code Tabulation Area and Gazetteer references with representative city coordinates.

USGuess does not use USPS proprietary ZIP databases, carrier route data, delivery-route maps, customer address data, or copied postal/third-party ZIP boundary maps as quiz material.
