20250117 - DCV email - WHOIS query definitively abandoned

We told you about it a few weeks ago, the deprecation of WHOIS query has finally been voted by the CA/B Forum.

The consequences

This vote has 2 objectives:

  • prohibit the use of email addresses registered in WHOIS during DCV validation
  • prohibit the reuse of domain validation if the latter was based on a DCV email that used a WHOIS email address

The authorities' calendar

Each authority has set up its own calendar to comply with the new recommendations of the CA/B Forum.

Please note: There are several ways to consult WHOIS information to collect data:

  • automatically via the WHOIS protocol
  • manually via a WHOIS web search when the first method does not yield anything

Here is the calendar indicating the deadlines for each authority and each type of consultation:

Sectigo DigiCert GlobalSign***
End of manual searches -* 2025-01-08 2025-01-15
Expiration of DCV validations carried out on the basis of manual searches -* 2025-01-08 -
End of searches via the WHOIS protocol for the tld .nl 2025-01-15 2025-05-08 -
End of searches via the WHOIS protocol 2025-06-14 2025-05-08 2025-07-15
Expiration of DCV validations based on the WHOIS protocol -** 2025-07-08 -

* Sectigo has stopped using manual search since 2021.
** DCV pre-validation does not exist at Sectigo. The DCV challenge must be re-validated for each new request (new order, renewal or reissuance).
*** We do not have a calendar for GlobalSign, so we indicate here the dates planned by the CA/B Forum.
