A dealer license number is the identifier your state agency assigns to your licensed dealership. A dealer plate is a separate physical plate you buy after you are licensed. People search the two phrases as if they were one thing. They are not, and mixing them up costs time at the DMV and at the auction desk.
Below: what each is, what the official sources we read say about them, and how a license shows up when you register at a dealer auction.

What is a dealer license number?
It is the license identifier the state issues when your application is approved. The name for it depends on the state, and that is why one blog's "dealer number" is another state's "GDN."
- California calls it an occupational license number. The DMV's Occupational License Lookup lets you search by business name, city and ZIP, or by the occupational license number, and Vehicle Dealer is one of the listed categories (California DMV, checked 2026-10).
- Texas issues a GDN, a general distinguishing number, in separate Independent Motor Vehicle and Wholesale categories (TxDMV). TxDMV's dealer menu also links to a Dealer License Lookup.
- Oregon issues a Vehicle Dealer Certificate, listed in the state's license directory.
In practice you will find the number on the license document your agency issues and in the agency's online account. If you want the exact term for your state, see the dealer license guide for your state and the dealer license classes explained post.
What does a dealer license plate mean?
A dealer plate is a plate issued to a licensed dealer. The sources we read treat it as its own line item, separate from the license fee:
| State | Dealer plate cost | License fee in the same source |
|---|---|---|
| California | $92 per dealer plate at renewal, plus county fees if applicable | $125 renewal application fee |
| New Hampshire | $800 for the first retail dealer plate (from Jan 1, 2026) | $125 due with the application |
| New Jersey | $257.50 for a set of five dealer license plates and registrations | $100 dealer license fee |
Sources: California DMV, New Hampshire DMV, New Jersey MVC. The California license fee comes from the same DMV page, the other two from the cited state documents in our dealer dataset.
The takeaway is price, not definition: the plate can cost as much as, or several times more than, the license fee. California's page also says that if you are not renewing all of your plates you must file form OL 247 for the plates you are not renewing, so plate counts are tracked.
What the plates may legally be used for, and how many you can get, is set state by state. We did not verify use rules for any state, so read your agency's plate rules before you put a dealer plate on a car.
Where is the dealer license number used at an auction?
It depends on the auction, and it is not always a field you type.
Manheim. Manheim's registration FAQ says "Auction Access is a dealer authentication service that confirms you are an authorized dealer." After you submit verification materials, Auction Access issues an ID number. To sign up on Manheim you enter that Auction Access ID plus the last four digits of your Social Security number or government identification (Manheim FAQ, checked 2026-10). So the license number goes to Auction Access, and Manheim sees the Auction Access ID.
Copart and IAAI. We could not load the registration requirement pages for either, so we do not state what they ask you for. Their registration flows tell you which documents your state needs once you start an account.
Auction rules for your state also decide what the license lets you buy. For the licensing side of Copart and IAAI lots, see how to get a car auction and dealer license.
What should you check before you use the number?
- Match the name. The business name on the license has to match the name on your auction account and tax paperwork.
- Check the status and dates. Look yourself up in your agency's lookup, if it has one, the way a buyer would.
- Know the renewal date. An expired license is the same as no license for most dealer-only access. See dealer license renewal.
- Keep the plate paperwork separate. Plates have their own fees and, in California, their own form.
Where this fits in a flip
The number gets you in the door. It does not make a car profitable. Once you are registered, price the buy with the max bid calculator so the license, bond and plate costs are covered by margin on the units you actually sell.
How do you get a dealer license number?
You apply to your state agency, pay the license fee and meet the state's conditions, and the agency issues the license and its number. Fees in our dealer dataset show how much the first step varies: Alabama lists $125 for the Master Dealer License (Alabama Department of Revenue), Texas lists $700 per GDN category, and California lists $175 for a new dealer license application and $125 to renew (California DMV). Bonds and other conditions come on top. The dealer license list by state shows the bond range and sales threshold for each state, and the getting a dealer license guide covers the steps.
