The U.S. Census Bureau (USCB) is seeking information from vendors to enhance its Address Listing Field through a Request for Information (RFI) focused on acquiring address data in hard-to-reach areas. The objective is to strengthen the Master Address File (MAF) and the Topologically Integrated Geographic Encoding and Referencing (TIGER) System by obtaining address and location data for Living Quarters, including Housing Units, Group Quarters, and Transitory Locations, particularly in remote regions such as Alaska, Maine, the American Southwest, and Puerto Rico. Interested vendors are required to provide address points with x,y coordinates, location descriptions, file-level metadata, and a data quality report, with submissions due by 12:00 PM EST on February 5, 2026. For further inquiries, vendors may contact Paul W. Boesch at paul.w.boesch@census.gov or Jim Brooks at james.n.brooks.jr@census.gov.

RFI - Address Augmentation.pdf

The United States Census Bureau (USCB) has issued a Request for Information (RFI) to identify data solutions for augmenting its Address Listing Field, specifically targeting hard-to-reach areas not covered by standard addressing systems. The USCB seeks address and location data for Living Quarters (LQs), including Housing Units, Group Quarters, and Transitory Locations, in remote regions of Alaska, Maine, the American Southwest, and Puerto Rico. Contractors must provide address points with x,y coordinates, location descriptions, file-level metadata, and a data quality report. The data needs to be ingestible in a machine-readable format monthly. Responses are due by February 5, 2026, and should address methodologies for data development, accuracy, update frequency, security, licensing, and pricing. The RFI is for planning purposes only and does not guarantee a future RFP.

***This RFI is issued solely for planning purposes only and does not constitute a Request for Proposal (RFP) or a promise to issue a Request for Proposal (RFP) in the future. Further, the USCB is not seeking proposals and will not accept unsolicited proposals at this time.*** Interested vendors are advised that the U.S. Government will not pay for any information or administrative costs incurred in response to this RFI; all costs associated with responding to this RFI will be solely at the interested party’s expense. Not responding to this RFI does not preclude participation in any future RFP, if any is issued in the future. Lastly, this RFI does not commit the Government to contract for any supply or service whatsoever. The Government is not obligated to respond to any submissions received under this RFI.

In support of USCB’s strategic goals and objectives, the USCB seeks to obtain address data in hard-to-reach areas to further strengthen the address frame in the Master Address File (MAF)/Topologically Integrated Geographic Encoding and Referencing (TIGER) System. All data created, produced, and stored in MAF/TIGER will be the property of the USCB.

**Interested vendors shall submit their response no later than 12:00 PM EST on Thursday, February 5, 2026.**
