Vendor Registration Process


e-Sourcing does not support Computers/Tablets running the Linux, Apple OS or Android operating systems.



In 2010, the District of Columbia’s Office of Contracting and Procurement (OCP) transitioned to an electronic solicitations system. This change has allowed OCP to develop a streamlined system, eliminating the need to produce multiple printed copies of bids.


To receive electronic notifications, your company must be registered with OCP’s electronic solicitations system, eSourcing. All information required to complete the registration is notated by an asterisk.

Each company’s tax ID number represents one eSourcing account.  Each account may have multiple users. At the time of registration, you will be able to create one user account. The User ID must be an email address in order to receive your password link.

Additional users can be added at any time by the OCP Helpdesk staff. If you have provided goods or services for the District in the past, a placeholder exists in the system based on your Tax Identification Number and will prevent registration of the company a second time. You will need to provide the following information to [email protected] to have your company's account updated:

  • Company Name
  • Tax ID Number
  • Main Company Telephone Number
  • City
  • State
  • Point of Contact Name
  • Point of Contact Email
  • Point of Contact Telephone Number

All registrations must be completed 24 to 48 business hours BEFORE the closing date and time on the solicitation. If you have an issue during this window, we cannot guarantee the resolution of your problem in time for your company to successfully submit your bid.

Please allow 24 to 48 business hours for registration confirmation.


Purchase Orders (PO's) are transmitted via the ARIBA Supplier Network (ASN).  The ASN works in conjunction with PASS to generate a copy of the order directly to the Supplier’s account. At this time, registration is required to receive purchase orders. You will be issued an ARIBA Network ID number, which must be provided to the contracting staff during your PO registration. Please be sure to read all of the information concerning fees on the ARIBA Supplier Registration site.

Please note: non-profits and individuals using their Social Security Number are not required to register if no purchase order will be issued and the vendor will receive payment by Direct Voucher. Individuals using an IRS issued TIN are considered a Sole Ownership business entity and are required to register for an ANID number. If a vendor's ASN account is suspended, it will not preclude the vendor from bidding and being awarded a contract with the District.

ARIBA Supplier Network - Please read all information concerning any applicable fees when registering.
