01What the data says — and does not say
This page separates the checked GeoNames row for Heroica Matamoros—510,739, America/Matamoros, and source coordinates—from live travel claims. Those fields identify and compare the record; they do not prove current transport, accessibility, census totals, or a City Atlas Club visit.
Wikidata's localized description: municipal seat of Matamoros, State of Tamaulipas, Mexico.
02This city's dataset fingerprint
The source row behind Heroica Matamoros is GeoNames ID 3523466. Its recorded administrative path is Matamoros → Tamaulipas → Mexico, and GeoNames classifies the place as a populated place.

The city row itself was updated 2025-10-23; that date belongs to the source record, not to every transport or visitor detail in the real destination.

That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
