Crosswalk

ZIP by NDS Area Code Market™

Connect ZIP Codes with overlay-aware NDS Area Code Market Families™ without confusing observed geography with modeled allocation.

ZIP by NDS Area Code Market™ is the governed crosswalk layer that connects ZIP Codes with the NDS Area Code Market Families™ associated with their Area Code network relationships.

Lookup

Start with a ZIP.

Identify the NDS Area Code Market relationship or relationships associated with that ZIP.

Federation

Bring ZIP-native evidence into the market.

Housing, industry, workforce, wealth and other ZIP evidence can be summarized or compared through the governed market-family layer.

Modeling

Move from market evidence back toward ZIPs carefully.

Where the source does not contain ZIP, NDS can use the crosswalk to create modeled allocation estimates—but must label them as modeled rather than observed.

Methodology rule: a crosswalk creates a governed relationship; it does not invent an observed ZIP value that the source never supplied.

Public lookup / licensed dataset

Look up one geography. License the national crosswalk.

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.
