Permanent Trailer Identification 

Permanent Trailer Identification (PTI)


What is a trailer PTI?

Under the PTI program, most trailers are issued a PTI plate. Most trailers are issued a PTI plate and a permanent identification card rather than a regular trailer plate and registration card.


The department will issue the permanent trailer identification card and maintain an electronic record of ownership, whether a certificate of title requested or not.



  1. Certificate of Title

  2. Transfer without Certificate of the title

  3. Addition of legal owner


* A REG 4017 is a two-sided form used for trailers in the PTI Program

  • Side A: Completed and signed by sole owners requesting a paper certificate of title, requesting a paper certificate of title.

  • Side B: Transfer of ownership for a PTI Trailer with an electronic title record. The transfer may be a registered owner transfer or a release of the security interest only.

NOTE:  The application for duplicate or paperless title (REG 227) cannot be used if a PTI paper title was not issued.
