You'll need to report an issue to GMIS. In the field requesting your User ID enter "UNKNOWN." To save time, we suggest that you include the last four digits of the TIN, your email address, and explain the situation in the ticket. GMIS will verify the TIN, compare the email addresses, and provide you with your User ID. You can find the Need Assistance tile on the Bidder Registration Resource Center on our website at https://www.in.gov/idoa/2464.htm.
