A validated US ZIP code field with optional automatic State and Region lookup.
What respondents see#
A text field that validates the entry as a US ZIP code. Nothing else changes visually when State & Region Lookup is on — the lookup runs silently behind the scenes.
When to use it#
- Location-based screening or quota segmentation (e.g., quota by Census region).
- Store/dealer locator or shipping-eligibility questions.
- Any study that needs geography without asking respondents to type their state.
Configuring it in the builder#
Open Settings → State & Region Lookup and turn it on.
Settings reference#
| Setting | What it controls | Default |
|---|---|---|
| State & Region Lookup | Automatically derives State and Region from the entered ZIP and stores them as global variables | Off |
| Region Mapping | US Census 4 Regions or US Census 9 Divisions | US Census 4 Regions |
| Code Length (digits) | Required digit length for a valid entry, in the Validation tab (range 3–10) | 5 |
Turning the toggle on creates three global variables the first time it's enabled — ZipCode, State, and Region — which you can then use anywhere global variables are used: display logic, quotas, piping, or exports. See Variables & Panel Redirects.
Logic support#
ZIP Code is a validated text type — standard text operators apply (Equals, Contains, Answered, Not answered). For region- or state-based logic, condition on the State/Region global variables the lookup creates rather than parsing the raw ZIP. See Display logic — The condition builder.
