California Permanent Trailer Identification (PTI): Fees and Rules

Last verified: September 4, 2026

California registers nearly every trailer under the Permanent Trailer Identification (PTI) program: a permanent plate, no annual sticker, a $20 original fee, then $10 every five years to keep the record active, and $7 for a transfer or a replacement plate. Each of those is a DMV transaction, which Sticker Quicker, a licensed California DMV business partner (license OL 90656), files for customers statewide online.

Most fleet managers meet the PTI program the same way: a trailer gets pulled over, or a buyer asks for the title at the point of sale, and it turns out the paperwork everyone assumed existed never did. Trailers are the quiet part of a fleet. They do not renew every year, they do not get a fresh sticker, and so nobody thinks about them until the day they have to.

Here is the useful way to think about PTI: it is not annual registration at all. It is a permanent record with a five-year heartbeat. Miss the heartbeat and you do not lose a sticker. You lose the record.

This guide covers who has to be in the program, the exact 2026 fee schedule from DMV’s own page, the title decision that catches people at resale, and the deadline that quietly deletes a trailer from DMV’s file.

What the Permanent Trailer Identification program is

The Permanent Trailer Identification program is California’s registration system for trailers. DMV issues a permanent PTI plate and a PTI identification card that stay with the trailer for its life. There is no annual renewal and no yearly sticker. Instead, the owner pays a service fee every five years to keep the trailer’s record on file with DMV.

Two categories sit outside the program. Park trailers and trailer coaches are excluded from PTI and are registered annually instead. Fifth-wheel trailers and camp trailers are sorted between the two based on length, width, and size, so a fifth wheel may be registered as a trailer coach (not PTI) or as a camp trailer (PTI). DMV states this directly on its Commercial Vehicle Registration page, last modified August 7, 2026.

Tow and auxiliary dollies are the interesting edge case. California does not require them to be registered at all. You may register one as PTI voluntarily, and DMV’s own advice is that you probably should if you tow out of state, because other states’ requirements vary. If you decide not to register a dolly, DMV wants any existing license plate removed and surrendered.

The 2026 PTI fee schedule

These are the current figures published on DMV’s Registration Fees page, which was last updated June 30, 2026. Statutory authority is in the Vehicle Code sections shown.

California PTI fees, verified September 2, 2026

PTI transaction Fee Authority
Original registration or conversion into PTI $20 VC 5014
Service fee, every five years $10 VC 5014.1
Transfer of ownership $7 VC 5014
Replacement PTI plate $7 VC 5014.1
Replacement PTI identification card $7 VC 5014
Paper Certificate of Title (optional) $28 VC 9254
Electronic lien and title (ELT) record $28 VC 9254
Replacement title, if a paper title was issued $28 VC 9265

Cheap fees are not the same as an easy errand. Sticker Quicker is a licensed California DMV business partner, license OL 90656, and processes registration and title work on a real-time connection to the California DMV, then returns completed documents, plates and stickers by next-day FedEx. Customers are served statewide online and walk-in at the Fremont office, and fleet accounts get a dedicated DMV account executive.

Notice how far below standard vehicle rates these sit. A replacement license plate on a car costs $28. A PTI replacement plate costs $7. An ordinary vehicle transfer fee is $15. A PTI transfer is $7. Trailers are, on the fee schedule, the cheapest thing in a California fleet to keep legal. What they are not is the easiest thing to keep track of.

The five-year clock, and what actually happens if you miss it

This is the part that costs fleets real money, and almost nothing published about PTI explains it correctly.

DMV’s Vehicle Industry Registration Procedures Manual is explicit: owners of trailers registered under PTI are required to either pay a maintenance service fee or file a Planned Non-Operation certification every five years, starting with registrations expiring on or after December 31, 2006, in order to retain the PTI record on file with the department. Read that last clause again. The consequence of missing the five-year mark is not a late sticker. It is the loss of the record itself, which is the thing that proves the trailer is yours.

DMV does send a warning. About 60 days before the expiration date you receive a PTI service fee notice. Pay it and you get an acknowledgment notice back. You do not get a new sticker, because there is nothing to stick. For a fleet that sorts mail by “does this have a sticker in it,” a PTI notice is exactly the envelope that gets set aside.

The PNO option, and a number worth checking

The alternative to the service fee is filing a Planned Non-Operation certification (REG 102) for a trailer you are not using. That satisfies the five-year requirement and keeps the record alive. But look at the two published amounts side by side: DMV’s fee page lists the PTI service fee at $10 and the general planned nonoperation fee at $28 (VC 4604). On those published figures, taking a trailer out of service to save money would cost you more than simply keeping it registered. Confirm the treatment for your own account with DMV Motor Carrier Services before you build a policy on it, but the instinct that PNO is always the frugal option does not survive contact with the fee schedule.

The title decision most fleets get wrong

Here is the trap. Under PTI, a paper Certificate of Title is optional, and the default is that you do not get one.

DMV issues a Permanent Trailer Identification card and maintains an electronic record of ownership whether a Certificate of Title is requested or not. If a Certificate of Title is not requested, a Bill of Sale can be used to transfer ownership. However, if a physical Certificate of Title has been issued, it must be used upon transfer of ownership.

That language is printed on the PTI Certification and Application (REG 4017), revised January 2022. Three consequences follow, and every one of them shows up at the worst possible moment:

  1. If no title was ever issued, you are not missing paperwork. A bill of sale is the correct transfer instrument, and a buyer who insists on a title is asking for something that does not exist.

  2. If a title was issued, even years ago by a previous owner, it must be used. You cannot fall back on a bill of sale. That means locating it, or paying $28 for a replacement under VC 9265 first.

  3. A trailer financed through a bank or finance company is titled automatically, because a legal owner is on record. The PTI title fee applies. So any trailer that ever carried a lien almost certainly has a title somewhere.

The practical rule for a fleet: before you list a trailer for sale, find out which of the two situations you are in. Doing that on a Tuesday costs nothing. Doing it with a buyer standing in your yard costs a deal.

REG 4017 also carries a 10-day deadline

Section 4 of the REG 4017, the new-owner block, instructs the buyer to complete the transfer within 10 days of taking possession of the trailer. That is the same 10-day window California applies across vehicle transfers, and it is the one most often blown on trailers precisely because a trailer feels like equipment rather than a registered vehicle.

How to register a trailer under PTI

The document set depends on what you already have. DMV lists it this way:

  1. Start with a titling document: an out-of-state title, an Application for Registration of New Vehicle (REG 397), or a manufacturer’s statement of origin.

  2. If you do not have a REG 397, add an Application for Title or Registration (REG 343) and a Verification of Vehicle (REG 31).

  3. Add a Statement of Facts (REG 256) declaring the trailer’s unladen weight. DMV accepts the declaration in place of a weight certificate for this purpose.

  4. Add a PTI Certification and Application (REG 4017) only if there is no legal owner and you want a paper Certificate of Title. Complete Side A and include the PTI title fee.

  5. Pay the applicable fees, starting with the $20 original PTI fee.

At original registration you also make a plate choice: keep the trailer’s existing California trailer plate and take a PTI sticker, or take a PTI plate with no sticker. Personalized and special interest plates can be retained or requested for a PTI trailer, and if you go that route the special plate fees ride along at renewal.

Doing this yourself versus handing it off

The PTI transaction itself is cheap. The cost of getting it wrong is not, and neither is the cost of the staff time it takes to track a five-year deadline across a yard full of trailers that never send a reminder anyone recognizes.

Sticker Quicker is a licensed California DMV business partner, license OL 90656. For fleets, the piece that matters most here is not speed on any single transaction. It is that PTI deadlines are five years apart, which is longer than most staffing plans.

How PTI fits with the rest of a California fleet filing

PTI covers the trailer. It does not cover the tractor pulling it, and it does not satisfy the weight or carrier obligations that ride alongside. Two connections are worth knowing:

  • Weight. Commercial motor vehicles at 10,001 lbs GVW or CGW and above are assessed Commercial Vehicle Registration Act fees rather than weight fees.

  • Fleet-wide programs. If trailers are one line in a larger fleet, Permanent Fleet Registration and Partial Year Registration both change how the rest of the yard renews.

The short version

PTI is the least expensive registration California offers and the easiest to lose track of, and those two facts are related. Twenty dollars to enter, ten dollars every five years to stay, seven dollars to transfer. The trailer’s record outlives the plate, the sticker, and usually the person who filed the original paperwork. Set the reminder, know whether a title exists before you need it, and the program does exactly what its name promises.

Frequently asked questions

Do California trailers need to be registered every year?

No. Trailers registered under the Permanent Trailer Identification program are not renewed annually and receive no yearly sticker. The PTI plate stays with the trailer permanently. The owner pays a $10 service fee, or files a Planned Non-Operation certification, once every five years to keep the trailer’s record on file with DMV.

How much does PTI cost in California in 2026?

DMV’s Registration Fees page, updated June 30, 2026, lists $20 for original registration or conversion into PTI, $10 for the service fee due every five years, $7 for a transfer, $7 for a replacement plate, and $7 for a replacement identification card. An optional paper Certificate of Title costs $28.

Does a California PTI trailer have a title?

Only if someone asked for one. DMV issues a PTI card and keeps an electronic ownership record whether or not a Certificate of Title is requested. If no title was ever issued, a bill of sale transfers ownership. If a paper title was issued, it must be used at transfer. Trailers financed with a lienholder are titled automatically.

What happens if I miss the five-year PTI service fee?

The five-year payment is what retains the PTI record on file with DMV, so missing it puts the trailer’s record itself at risk rather than just adding a late sticker. DMV mails a PTI service fee notice roughly 60 days before the date. Paying returns an acknowledgment notice, not a sticker.

Which trailers are excluded from PTI?

Park trailers and trailer coaches are excluded and are registered annually instead. Fifth-wheel trailers and camp trailers are assigned to trailer coach (not PTI) or camp trailer (PTI) based on length, width, and size. Tow and auxiliary dollies do not have to be registered in California but may be entered into PTI voluntarily.

What form do I use to add a title to a PTI trailer?

The Permanent Trailer Identification (PTI) Certification and Application (REG 4017), revised January 2022. Complete Side A if there is no legal owner and you want a paper Certificate of Title, and include the PTI title fee. The same form’s Side B handles transfers and adding a legal owner without a title.
