There are specific eligibility requirements for businesses to work with Washington Public Agencies. As part of the registration process, MRSC verifies that businesses meet the minimum requirements before they are listed. More information about the roster statutes can be found in the Contracting Resources page.

After completing your initial application or renewing your account, MRSC Rosters verifies that you meet these minimum requirements. We do these verifications on Tuesdays and Fridays. If something is missing, we will email you to clarify.

Your account is not registered with MRSC Rosters until you have received an email confirming your verification is complete. Public agencies cannot find you until your account is registered.

If you do not respond, we will inactivate your account until we hear from you. If you have not received an email letting you know that your account has been verified and is active for the year, please reach out to us! We know emails can go to spam or junk sometimes, and we don’t want your business to not be registered because an email was missed.
