We are currently experiencing an outage for our Tin Match product due to a major outage in the IRS Tin Verification Service. We are monitoring the IRS outage to ensure all affected orders are remediated as quickly as possible after the IRS outage is resolved. In the meantime any Tin Match requests that can fulfilled via Middesk's TIN database will still proceed.

The IRS TIN Matching service has been restored and TIN Match is operating normally. Between approximately 12:10 PM and 7:10 PM PDT, TIN Match requests that could not be fulfilled via Middesk's TIN database were impacted by the IRS disruption. All affected orders have been automatically remediated and now reflect updated TIN results. No action is needed from customers.
