Switch to Alternative Domain Validation Methods Today

Stay compliant and secure—make the switch to approved validation methods to avoid disruptions.
WHOIS-based domain validation is being phased out. If you’ve been using WHOIS-listed email addresses for SSL/TLS certificate validation, it’s time to transition to a new method to ensure seamless certificate issuance.
Here’s the timeline:
| Phase | Sectigo | DigiCert |
| Phase 1 | Jan. 15, 2025 — Sectigo’s first phase of the rollout involved prohibiting the use of WHOIS-based email validation for .nl top-level domains. | Jan. 8, 2025 — DigiCert stopped supporting manual and HTTPS web-based WHOIS lookups for domain validations and prior use authorizations based on these methods. |
| Phase 2 | June 15, 2025 — Sectigo will no longer support WHOIS-based email DCV and will invalidate any pre-existing DCV records. This means no certificates can be issued or re-issued using these unsupported WHOIS-based DCV methods. | May 8, 2025 — DigiCert will no longer accept automated WHOIS-based domain validations/IANA referrals for new domain validations. It will, however, still accept WHOIS protocol-based DCVs. |
| Phase 3 | July 2025 — DigiCert will no longer allow the reuse of existing WHOIS-based domain validations of any kind, regardless of the time left in a reuse period. |
Recommended Solutions:
- Constructed Email Addresses: Use admin@, webmaster@, or other pre-approved addresses for your domain.
- DNS-Based Validation: Add DNS TXT or CNAME records to your domain.
- HTTP File Authentication: Upload a unique validation file to your website’s root directory.
