Selling to the State of Oklahoma

How a company registers as a supplier with the State of Oklahoma, the state's certification programs and drone programs, and where to get help in Oklahoma, with the official sources. Federal registrations such as SAM.gov are in the federal guides.

Oklahoma Supplier Portal (Office of Management and Enterprise Services, Central Purchasing)

How to register

1. 1Get a current, signed and dated IRS Form W-9 ready before you start. The Office of Management and Enterprise Services (OMES) registration guide says the W-9 is a required upload. International entities may upload a W-8BEN-E or W-8BEN instead.
2. 2Go to supplierportal.ok.gov and select Oklahoma Supplier Portal Login.
3. 3Select Register a New Entity or User. Under Supplier or Payee Registration, select Register now. OMES also offers a shorter Bidder Registration for viewing solicitations and bids, but it says a supplier ID is required for a contract award.
4. 4Welcome step: select your entity type, then select Next.
5. 5Identifying Information step: enter your IRS-issued taxpayer identification number with no dashes. OMES accepts a Social Security number (SSN), a federal employer identification number (FEIN) or an individual taxpayer identification number (ITIN). Answer every question marked with an asterisk and upload the W-9. OMES says entities without a U.S. federal tax ID cannot register in e-Supplier at this time.
6. 6Addresses step: enter your primary address. Do not enter the county. The U.S. Postal Service checks the address; select Accept address.
7. 7Contacts step: select Add Contact, fill in the required fields and create the user ID that will manage your supplier record after approval.
8. 8Categorization step: OMES says suppliers who plan to bid must pick at least one UNSPSC (United Nations Standard Products and Services Code) category code. The codes you pick decide which bid notices you receive. Suppliers who do not need bid notices can skip this step.
9. 9Submit step: confirm your email address, check the box to agree to the Terms of Agreement and select Submit. You can save a draft and come back later with your registration ID.
10. 10Watch for two approval emails. The second one has your user ID and a temporary password. Sign in at supplierportal.ok.gov, change the password, and give your supplier ID to your agency contact.
11. 11Keep the record current. OMES says there is no fee to self-register, category codes no longer expire, and keeping the registration current is the supplier's job. Help: Supplier Assistance Line 405-521-2930 (9 a.m. to 4 p.m. Central, Monday to Thursday) or OKSuppliers@omes.ok.gov.
