In rare instances, it is possible for the Self-Check service to match your check-in records to that of a COVID-19 case although you did not visit the location. It may happen when the address data provided by businesses is not accurate, which could lead to incorrect matches. If this occurs, please contact us here to let us know, or call the MOH hotline at 1800-333-9999 to let us know, so that we can verify this with the businesses involved.
