What the local source records show
The postal label for 92101 is San Diego, California. The 2020 crosswalk records San Diego County (06073) and San Diego city (0666000), and the FCC selection is the city report. California also publishes an annually collected provider-data map with separate CASF program uses. Read the map purpose and date before comparing it with the dated city-level FCC research.

Local ordering questions
Why does 92101 use San Diego city rather than San Diego County for provider research?
The source postal city matches the intersecting Census place, San Diego city (0666000). San Diego County (06073) is retained as boundary context. The FCC city summary is broader than 92101 and does not establish a technology, speed or eligible plan for a household.

What should I check when California mapping shows a provider or CASF project near 92101?
California’s map guide describes annual provider data collection and uses that include service research and CASF applicant eligibility. Those are different purposes. For your address and unit, ask which retail product is eligible, what equipment it needs and when installation can be confirmed.
