Crosswalk

City by NDS Area Code Market™

Cities make the market recognizable; the governed family identity keeps the data consistent.

City by NDS Area Code Market™ connects city and state relationships with the governed NDS Area Code Market Family™ layer.

Find a market from a city.

AreaCodeMarket.com can resolve city relationships into one or more governed market families where the evidence supports them.

Context

Give market families recognizable place names.

Primary-city and city-list signals help people understand a market while the governed identity remains the Area Code family code set.

Precision

Use city + state when it improves a crosswalk.

For datasets such as FTC consumer complaints, city and state can narrow the plausible ZIP candidate set rather than relying on Area Code alone.

Public lookup / licensed dataset

AreaCodeMarket.com supports public one-at-a-time Area Code, ZIP and city discovery. The complete national ZIP-to-market and city-to-market relationship datasets are not distributed as public browser downloads. Bulk data, API, white-label and integration access are licensed NDS products.
