Current status of Sumsub: Operational — live Sumsub status

Timeline

   identified
   We are experiencing an issue with International TIN Validation checks. Since October 28, 2026, 15:00 UTC, requests to our upstream data service have been failing intermittently and most TIN validation checks currently return errors. As a result, verifications that rely on International TIN Validation should be temporarily paused. All other Sumsub services are operating normally. We are working with them to restore the service and will post an update as soon as we have more information.

   monitoring
   The International TIN Validation service has been restored, and checks have been processing normally since 09:40 UTC on October 29. Clients who temporarily paused verifications relying on this check can resume them. We are monitoring the service to make sure it remains stable.

   resolved
   International TIN Validation is fully operational again. From 15:00 UTC on October 28 to 09:40 UTC on October 29, an issue with our upstream data service caused most checks to fail. Checks have been stable since recovery, with no further errors observed.
