Regional data
include=regions adds the transit areas, special districts and other published boundaries an address falls in. They
describe evidence only: they don't change rate or parts, establish an exemption, or add a tax.
Matches
regions.matches lists confirmed memberships, with the same shape in every state.
| Field | Description |
|---|---|
kind | transit, tax_area, special_district, civil, boundary_change, police_jurisdiction or incentive_zone. |
type, name | The publisher's type, and its name for the area (nullable). |
ids, attributes | The publisher's ids and original attributes, names and units unchanged. |
featureId | The feature's id within its snapshot. |
source | id, url, snapshotId, edition, observedAt, startsOn/endsOn, dateBasis, and a note. |
Coverage
regions.coverage gives each source's status: evaluated, unavailable, date_uncovered, location_uncertain, incomplete or error. Only evaluated with no match means the
address is outside that source's areas. A local source (Montgomery's police jurisdictions) says nothing about the rest of its state,
and if placement is uncertain across a boundary, that membership is left out and the source marked uncertain.
Dates
Dated editions are chosen for the requested date. Undated sources give their latest snapshot for today's lookups, with dateBasis: "latest_snapshot"; its observedAt is not a legal effective date. Regional lookups may need extra
geocoding.
