Vendor Registration Info

In order to do business with the County of Los Angeles, suppliers must first register in the County’s vendor registration system.

This process alerts the County as to the products and services that each supplier has to offer. The registration process only takes a few minutes and may be done electronically. All that is needed is access to the Internet. If your company does not have Internet access, you may gain access through any public library. Once you enter the website, you will be led through the registration process using easy-to-follow instructions.

As a registered supplier, you will become part of the County’s vendor data base giving your company visibility to all Procurement Offices in the County. This data base may be used by all County departments to solicit bids. If you supply an e-mail address during the registration process, you will receive e-mail notifications of solicitations for commodities and services for which you are registered.
