Address List Field Augmentation Data

The United States Census Bureau is conducting market research to identify small‑business sources capable of providing address list field augmentation data for hard‑to‑reach locations. The effort is a Sources Sought Notice (SSN) and does not constitute a solicitation or guarantee of contract award. Respondents must demonstrate capability to acquire, verify, and deliver geospatial address data in FGDC‑standard formats, including metadata and quality‑assurance reports, on a regular monthly schedule. The agency is specifically seeking small, disadvantaged, 8(a), SDVOSB, HUBZone, and women‑owned firms. Responses are limited to seven pages and must be submitted by noon Eastern Time on November 6, 2026. • Collect and generate address points, coordinates (≥5‑decimal‑place precision), and metadata for remote or non‑civic addressing zones. • Provide data‑quality reports covering completeness, logical consistency, positional accuracy, temporal quality (≤5 years old), and thematic accuracy. • Describe pricing structures for individual address records and aggregated datasets, and explain risk mitigation, tribal collaboration, and discrepancy handling.
