About

TIGERweb is a geographic web service operated by the US Census Bureau that provides direct access to the Topologically Integrated Geographic Encoding and Referencing (TIGER) database. Through standard ArcGIS REST map and feature services, applications can query boundary polygons, spatial identifiers, and linear features including states, counties, census tracts, census blocks, incorporated places, and ZIP Code Tabulation Areas.

Through Fibric, an operator queries boundary polygons and spatial intersections, proposing territory assignments for dispatch crews or demographic benchmark tags for commercial facilities.

This is a reference listing. It documents what Fibric would read from TIGERweb and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • Administrative and statistical boundary polygons via TIGERweb MapServer layer queries
  • Census tract and census block identifiers and geometries from the Census 2020 or Current layer sets
  • County, state, and metropolitan statistical area boundaries and FIPS codes
  • ZIP Code Tabulation Area boundaries and spatial outlines via ZCTA5 layers
  • Linear feature geometries for national road networks, rail corridors, and hydrography
  • Spatial relationship queries filtering boundary intersections by point coordinates or bounding envelopes

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Assign field dispatch territories by census tract

    Query TIGERweb boundary layers with customer coordinates, proposing precise territory and service team assignments based on municipal boundaries.

    With Field Dispatch, Territory Balance

  • Validate delivery zone boundaries against municipal limits

    Compare physical delivery address coordinates against incorporated city limits to propose accurate local tax jurisdiction and delivery surcharge tags.

    With Address Repair, Customs Declaration

  • Tag commercial properties with census geographies

    Intersect facility coordinates with TIGERweb tract and county layers, proposing standardized FIPS tags for cross-facility reporting and analysis.

    With Site Benchmark

Requirements

  • ArcGIS REST query parameters such as geometry, spatialRel, where clauses, and outFields
  • Coordinate system definition matching spatial inputs (typically EPSG:4326 or EPSG:3857)
  • Target layer selection distinguishing between Current vintage and decennial Census benchmarks
Authentication
None. TIGERweb map and feature services are public ArcGIS REST endpoints requiring no authentication or API keys.

Limits

  • ArcGIS Server limits query responses to a maximum of 1,000 to 2,000 feature geometries per request
  • Complex multi-ring boundary polygons require generalization parameters to prevent query timeouts
  • Boundaries reflect legal and statistical boundaries rather than postal delivery routes

Questions and answers

What interface does TIGERweb expose for spatial queries?
TIGERweb exposes ArcGIS REST MapServer and FeatureServer endpoints under tigerweb.geo.census.gov, supporting spatial intersections, attribute queries, and GeoJSON or Esri JSON exports.
What is the difference between ZCTAs and USPS ZIP Codes?
ZIP Code Tabulation Areas are generalized areal representations of USPS mail delivery routes built by the Census Bureau. They approximate ZIP Code service areas but do not cover unpopulated mail routes.
Are there usage fees or access tokens required for TIGERweb?
No. TIGERweb is a public service of the United States Government and is accessible free of charge without registration or API tokens.
