What the local source records show
Topeka city is the named-place intersection for 66603, while Shawnee County is its county context. The FCC provider report uses Topeka's place GEOID, not a generic Shawnee label. Kansas separates its approved BEAD proposal from archived program materials, so retain the document's stage and date when researching a Topeka project.

The geography vintage is 2020. The public source records support this geographic interpretation; they do not confirm service at a household.
