REG 4017 Form – If you own or are buying a trailer in California, you’ve likely come across the REG 4017 form—officially known as the Permanent Trailer Identification (PTI) Certification. This essential DMV document handles title requests, ownership transfers, and legal owner updates for trailers in the state’s Permanent Trailer Identification program.
Whether you’re registering a new trailer, transferring ownership, or requesting a paper Certificate of Title, the REG 4017 PDF is the go-to form. In this comprehensive guide, we’ll cover everything you need to know: what the form does, who needs it, how to fill it out step by step, current fees, submission tips, and answers to frequently asked questions—all based on the latest official California DMV sources.
What Is the Permanent Trailer Identification (PTI) Program?
California’s PTI program simplifies trailer registration. Instead of annual stickers and renewals, eligible trailers receive:
- A permanent PTI license plate
- A Permanent Trailer Identification Card
- An electronic record of ownership maintained by the DMV
The program applies to most non-commercial and certain commercial trailers. Key benefits include no yearly registration fees—only a low maintenance service fee every five years (currently $10).
Important exclusions: Trailer coaches, park trailers, and certain other types do not qualify for PTI. Always verify eligibility with the DMV before proceeding.
Why Do You Need the REG 4017 Form?
The REG 4017 (revision R1-2022, still current as of 2026) is a two-sided form specifically for PTI trailers. Use it for:
- Requesting a paper Certificate of Title (Side A)
- Transferring ownership when no paper title was issued (Side B)
- Adding or releasing a legal owner/lienhoder
- Original PTI registration or certain conversions
Note: The DMV automatically issues a PTI card and electronic record. A paper title is not automatic unless there’s a lienholder. If you want the physical title, you must request it on this form.
This form cannot replace a lost, stolen, or damaged title—use REG 227 instead.
