# Contractors Resolve SAM.gov Address Validation

USFCR says SAM.gov address validation generally favors a real business location with exclusive, documented use, and identifies PO boxes, mailbox rentals, virtual offices, shared workspaces, and registered-agent addresses as common rejection triggers. For a legitimate address that is flagged, the article recommends submitting a lease and supporting records to the Federal Service Desk (FSD), requesting a CAGE validation review, and citing KB0058176. It suggests congressional constituent-services escalation if a case remains unresolved for more than two weeks. Because this is commercially published guidance rather than an official government policy notice, contractors should confirm procedures with FSD.

- Companies registering or updating in SAM.gov should ensure their address documentation supports exclusive use of a real business location; the article warns that certain alternative address types may be rejected.
- For a flagged legitimate address, the recommended steps are to provide lease and supporting records to FSD, request CAGE validation review, and reference KB0058176.
- If an issue remains unresolved for more than two weeks, the article suggests contacting a congressional representative’s constituent-services office. Contractors should verify this escalation path and current requirements with FSD.
