Vendor Registration

ATTENTION: All OMES vendor forms have been updated. Please visit Central Accounting and Reporting Forms to download the most recent forms.


Vendors pending contract award to a bid released by Central Purchasing or other Oklahoma state agency must register with the state.


Online vendor registration is required of all payees of Oklahoma state agencies. However, the registration type and its requirements differ based on the purpose of payment and whether a procurement activity is applicable.

When creating a new registration account, registrants must select from two different registration account types:

  • Bid Notification Registration (Procurement)

This registration type serves to register the entity for bid notification and procurement qualification purposes.

Registration entitles a supplier to receive all bid notices for the commodity classes specified within the registration process for a period of one year. Additionally, contracts or purchase orders greater than $5,000 which are subject to 74 O.S The Central Purchasing Act and Rules, require the vendor to be registered prior to agency award. There are limited circumstances where an exemption to this registration requirement may be granted, such as Fair and Reasonable acquisitions less than $5,000, Fixed Rate acquisitions, Professional Service acquisitions, and Interagency or other Governmental entity acquisitions. This registration process includes direct deposit enrollment, procurement qualification, as well as bid notification registration for UNSPSC category codes matching the goods or services offered by the vendor. BID NOTIFICATION registration is subject to a $25 registration fee per FAMILY code registered and requires annual renewal.

  • Financial Registration (Direct Deposit Enrollment)

This registration type should be selected by individuals and businesses receiving payments from Oklahoma state agencies where an exchange of goods or services is not applicable or where a procurement registration exemption is applicable. Entities providing goods or services, should first verify the registration type required by the state agency prior to registering. 


Pursuant to 74 O.S. § 85.33.B:

  • A vendor may register with Central Purchasing to be placed on the supplier list for bid notification.

  • Registration entitles a supplier to receive all bid notices for the commodity classes specified by the vendor in the registration process for a period of one year. 

  • The vendor registration fee is $25 for each family code for which the vendor desires registration.

  • Vendor registration must be renewed annually.

  • Registered vendors will be automatically notified of opportunities to do business with the state for the specific commodities for which they chose to register for notification.

  • The following items describe information requested by the vendor registration application. To expedite the application process, vendors are encouraged to have the information readily available prior to beginning the registration application. If your company is not currently transacting business in the State of Oklahoma, you may not have some of the items listed. However, any vendor selected for award of a contract with the state of Oklahoma must meet the requirements prior to the issuance of a purchase order.

    • Email address - if possible, we encourage all vendors to create a central email address, to which all state bidding e-mail correspondence can be sent. A central email for your organization will assure personnel changes or employee absences do not inhibit your ability to receive timely notifications of state bidding opportunities.

    • An Oklahoma Sales Tax Permit Number and its expiration date, or an explanation of the claimed exemption status. (FAQs) For additional information regarding the Oklahoma Sales Tax Permit requirements, visit the OKTAP website or contact the Oklahoma Tax Commission Permit offices directly at 405-521-3160.

    • An Oklahoma Secretary of State filing number, or explanation of the claimed exemption status. For additional information concerning the Oklahoma Secretary of State filing requirements, visit the Oklahoma Secretary of State website or contact the Oklahoma Secretary of State Business Filings offices at (405) 522-2520.

For additional information concerning Oklahoma Workers' Compensation insurance coverage requirements, visit the Worker’s Compensation Commission website or contact the Oklahoma Workers' Compensation Commission at (405) 522-3222 or Toll Free (855) 291-3612.

      Effective May 1, 2020, a new certificate holder address will be applicable for Worker’s Compensation Liability Insurance Certificates provided by vendors to Oklahoma state agencies for state procurement contracts and purchase orders.

      Agencies should contact their vendors and request all future documentation submitted reflect the below information in the Certificate Holder field on the bottom left corner of the Worker’s Compensation Liability Insurance Certificate. Vendors should contact their insurance providers to notify them of the changes and to request an updated certificate be issued. Insurance providers may submit all annual renewal certificates via email to Documents not provided by the insurance agency directly, should be uploaded by the vendor within Step II of the vendor’s online registration account.
