If you purchased your domain from a registrar other than Yahoo!, or you purchased a domain through Yahoo! before January 22, 2001 (or, for Merchant Solutions customers, March 23, 2001), you will need to contact your registrar to make any changes to your contact information (you'll be able to manage certain other domain features in your Domain Control Panel). Learn how to identify your registrar.
Owners of all domains registered through Yahoo! after the dates noted above can edit their contact information in the Domain Control Panel.
To edit your domain contact information:
Please remember that changes to domain name registration information can take up to 24 hours to be reflected in the public WHOIS database.
Even if you choose to conceal your contact information from the public by using Yahoo! Private Domain Registration, you can edit this information anytime. We recommend keeping your contact information up-to-date in the event that your domain name registrar or another third party needs to contact you regarding any technical or legal issue with your domain name. Including current contact information will also ensure that you receive notification when it's time to renew your domain.
