How These Figures Were Built
These figures are estimates based on public phone-number assignment records. They are meant to show the likely mix of assigned phone numbers associated with Napa, California, not live customer counts.
Some providers may have assigned phone numbers tied to this locality even if they do not actively market or sell service locally. These figures reflect public number-assignment records, not confirmed local service availability.
They also do not reflect number portability at the individual phone-number level, so some numbers may now be used on a different network or by a different provider than the original assignment records suggest.
