How to Register as an IAA Buyer Online

Registering as either an Individual (Public) or Licensed Business Buyer is easy. Our improved online registration system lets you conveniently sign up from your desktop, tablet or mobile device. Simply follow this step-by-step guide and you’ll be bidding and buying in no time. 

1. Create your Account

Enter your first name, last name, e-mail and a password to start the registration process. Once complete, you’ll be prompted to finish your profile with important information such as your primary activity, preferred language, country and mobile phone number.

2. Selecting a Business Type

Individual (Public) Buyers
Individual Buyers can bid at auctions that are open to the public (varies by state) and on vehicles that can be sold to the public.

If you are in a state that does not permit public buying, you will be prompted to either continue registration confirming you are aware that you cannot bid in your state and must find a broker who can help you purchase inventory, or upgrade to a business account.

Note: Individual Buyers should confirm that a vehicle they wish to bid on is located at a branch open to the public and is available for public purchase. Buyers can check the ‘Who Can Bid’ list found on the drop-down menu in Bid Information on the Vehicle Detail Page at

Licensed Business Buyers

As a Business Buyer you can bid at auctions on inventory where your business license meets state requirements.


3. Upgrade to a Buyer Account or Continue as a Guest

You can either select ‘Continue’ to complete your registration as a free guest account, or you can select ‘Upgrade’ to start your registration as a paid buyer.

4. Gather Your Documents

To register online you will need to provide the following valid, up to date documents:
A government issued ID (choose one):

  • Driver’s license
  • State ID
  • Passport

If your ID does not include your address, IAA will need proof of address (choose one):

  • Tax payment
  • Utility bill
  • Another official document that includes your name and address

To register as a Licensed Buyer, you will also need:

A Business License

License Requirements within the United States: 

You can register as a Licensed Business Buyer with an automotive-related business license. If you do not have an automotive-related business, you can still register by selecting the “other” license type option.  

A non-automotive related licensed business is limited to bid on the same inventory as Individual (public) Buyers in most cases. This business type is not tax-exempt, but benefits from a License Business Buyer fee structure. 

License Requirements from Outside the United States: 

If you are located outside the United States, you can only register as a Licensed Business Buyer if you have a business license for an automotive-related business such as: 

  • Dealer
  • Dismantler
  • Importer
  • Exporter
  • Rebuilder
  • Repair Facility
  • Scrapper
  • Body Shop

Resale Certificates (for sales tax exemption)

While some states issue an annual resale certificate, others require us to collect the state-issued tax license, and the resale form approved by the state, for us to allow tax exemption. Those states that do not issue a tax license, but charge sales tax at the point of sale, still require us to collect the state-approved resale form in order to allow tax exemption. 

  • Resale Certificates for sale tax exemption can be completed at a later date. Please note, buyer is responsible for providing payment by due date and submitting needed resale certificate to be sales tax exempt.
To view all resale certificates, please visit the IAA Help Center.
