You can change your domain's contact details anytime from your panel. Just log in to your Hostinger account, go to the Domains section, and click on Manage next to the domain you wish to change contact details:
Open the Domain Ownership tab, and choose the type of contact details you want to change:
Registrant – domain owner.
Administrative – main manager of the domain.
Billing – person in charge of domain-related payments.
Technical – webmaster or IT department.
Then, click on Change contacts:
Once there, select Create New Profile:
Fill in all the details and click on Create profile:
Once created, you will be asked to use this profile. We recommend ticking the checkbox to use the profile for all domain contacts. Then, click on Use contact:
Next, you will receive a verification message to your domain's registered email address requesting approval of the change. If you are updating the email address as well, the message will be sent to both the current and the new addresses.
Changes will only be applied after you have verified them via email – make sure to check your spam folder as well 💡
NOTE
If domain privacy is disabled, it might take up to 24 hours for the updated details to be visible on WHOIS.
