# resolveTaxJurisdictionByPostal

query · in the family [Reading your records](/reference/reading-your-records/)

## What it does

Find the tax jurisdiction that applies at a postal code — type a ZIP, get the place.

Resolve a postal code to the tax jurisdiction(s) that apply there: ONE bounded read; the primary designation leads, straddling alternates follow. An unknown code — or a country without postal content — answers the honest empty resolution (primary null, alternates). Malformed input refuses VALIDATION/INVALID before any read. SHARED canonical data — no tenant scoping. Requires authentication.

## What happens

Reads shared platform tax data. Most codes answer one jurisdiction; a code straddling city or district lines also lists the alternatives, with the usual designation first. An unknown code answers empty.

## Who may call it
