FMCSA Announces Three-Month Extension of Unified Registration System Effective Date. FMCSA is delaying the implementation of the final stage of the Unified Registration System (URS) until Jan. 14, 2017, with a new full compliance date of April 14, 2017. The agency is currently updating its information technology systems and undertaking a complex migration of millions of records to remote storage servers. This work will provide the agency and its state partners a foundation to successfully launch the final stage of URS. The agency estimates that the initial phase of URS, launched in December 2015, has saved the industry approximately $1.6 million in processing time during the first six months. To date, FMCSA has issued 62,000 USDOT numbers, removed 340,000 dormant USDOT numbers from agency databases, and screened 100% of operating authority applications for reincarnated carriers.
