D-Trust: Issuance of an EV certificate containing a mixup of the Subject's postalCode and localityName

RESOLVED FIXED D-TRUST
AI Summary

D-Trust issued an EV certificate with a mix-up between the Subject's postalCode and localityName, which was reported by a third party. The affected certificate was revoked within the required 5-day period. The issue arose during the application process and was not detected by validation specialists due to the use of free text fields in the application form. D-Trust has since implemented a postcode check and conducted training for validation specialists to prevent similar issues in the future.
