Copart vs IAA: which salvage auction fits you?

By Marcus Hale, Editor. Last updated September 10, 2026.

Copart and IAA are the two largest salvage vehicle auctions in the country, both selling insurance total-loss and lender units online. Neither is simply better: the real differences are state-by-state access rules for non-licensed buyers, membership tiers, fee schedules and inspection photos, and the right pick usually comes down to which one lists the lot you want.

Who can actually bid

Copart accepts public registration, but for salvage title and other non-clean-title lots your access still depends on your state and the lot's title type. Some states require a licensed dealer or broker to bid on salvage titles at all, and neither company publishes a plain state-by-state chart, so the fastest way to find out where you stand is to start the registration flow on the specific lot you want. IAA works the same way in principle. Individual buyers and licensed business buyers can both register, and IAA also serves buyers outside the country through a network of brokers and its own Market Alliance members, active in more than 170 countries by its own account.

Membership works differently underneath. Copart names Basic and Premier member tiers on its site, but the current prices sit behind a login page we could not reach this month, so treat any figure you see elsewhere as unconfirmed until you check copart.com directly at the time you register. IAA frames its own entry point as "Register to Buy" with no membership cost stated on the page, though its buyer-fee schedule still varies by whether you register as a standard-volume, high-volume or non-licensed buyer. Read that as a warning that the sticker price you see quoted somewhere else may not match the account tier you actually get.

Fees side by side

This is where the two platforms diverge most, and it is also where the numbers change most often. Both companies publish tiered buyer fee schedules that scale with the hammer price rather than a single flat percentage, and both add per-unit charges on top. Copart's fee schedule was reachable this month; IAA's numeric tiers were not, so we are naming only the flat charges IAA states plainly and describing the tiered portion in general terms.

Add these up before you bid, not after. A $6,000 hammer price on either platform can carry another $500 to $900 once the buyer fee, gate or service charge, title work and any late or virtual-bid fee land on the invoice, and that is before you have paid to move the vehicle. Our companion guide on auction fees explained breaks each of those charges out further.

Inspection and photos

Neither company sends a mechanic to every lot. Copart marks eligible vehicles with a run and drive indicator, and IAA sells an optional Premium Imagery Set with extra photos on some lots, but neither publishes a guaranteed number of preview days before bidding closes, so plan around the sale date rather than the inspection window. What you get by default is a photo set, a title-status label and whatever condition notes the seller or the platform attaches to the listing.

Given that, a private buyer's real inspection is the paperwork, not the pictures. Before you commit money on any salvage-title lot, run the VIN through the National Motor Vehicle Title Information System to see the title-brand history, and read our guide on how to read a condition report so you know which abbreviations actually matter. If a lot is close enough to reach in person, use the in-person preview; if it is not, budget for a paid third-party inspection before you set a maximum bid.

Payment, pickup and storage

Both platforms expect payment within a few business days of winning, not weeks, and both charge a late fee if you miss the deadline. Copart's own schedule ties a roughly $50 late charge to about 3 business days after the sale; IAA does not publish an equivalent number where we could check, so assume a similarly short window and confirm it in the buyer agreement before you bid. On both platforms, an unpaid or uncollected lot keeps costing you: Copart can apply a storage-style relist charge near 10% of the sale price if a purchase falls through, and both companies require a paid receipt plus identification before the yard or branch will release a vehicle to you or your hauler.

Pickup itself is a logistics problem either way. Neither platform runs its own fleet of tow trucks for every buyer, so most private purchasers arrange transport separately once the vehicle is paid for and the release paperwork is in hand. If the lot cannot be driven away, plan on flatbed transport and build that cost into your maximum bid before the auction, not after you have already won.
