Move resumes the crackdown aborted in 2025
The U.S. Postal Service has drawn a hard line on driver eligibility for its massive linehaul network. In a letter dated April 16, 2026, Chief Logistics Officer and EVP Peter Routsolias notified all suppliers that effective May 1, non-domiciled holders of Commercial Driver’s Licenses (CDLs) may not transport mail under Postal Service contracts or ordering agreements unless they have been screened and badged by the U.S. Postal Inspection Service (USPIS).
“Suppliers must ensure that any driver assigned to Postal Service work has satisfied all applicable screening and clearance requirements before performing service,” the letter states. “It is the supplier’s responsibility to provide the required forms and information for clearance processing.” Suppliers with questions are directed to contact their designated Administrative Official.
