It’s important to keep your domain names’ registrant, administrator, technical, and billing contact information (also known as your Whois information) updated at all times. We use this information to notify the pertinent contact of changes or requests for your domain names.

NOTE: If your domain name has privacy, see Updating Contact Information for Domain Names with Privacy for more information.

1. Log in to your Account Manager.
2. Next to Domains, click Manage.

Which procedure you’ll use depends on the number of domains in your account:

6 Domains or Fewer

Select the domain name you want to use, click Text Icon (Settings) and select Domain Settings.
Under Contact Information, click Edit.
To edit All Contacts, simply enter the Contact, Address, Phone, and Email information you want to update, and then click OK.
To edit each individual contact, deselect the Use for all contact types box and enter the information you want to update.
Click OK.

More than 6 Domains (i.e. 7 or More)

1. Select the domain names you want to update.
2. From the Contacts menu, select Contact Information.
3. Select the contact type you want to change or select Edit all contacts.
4. Enter the Contact, Address, Phone, and Email information you want to update, and then click OK.

If you change the Registrant’s Contact information, read and select any of the following legal agreements that display:

• I certify that the organization listed above is the registrant and I am authorized to act on their behalf.
• I certify that I am either the individual named above or authorized to act on their behalf.
• I have read and agree to the terms and conditions below and understand that the domain name cannot be transferred within the next 60 days:

WARNING: You voluntarily agree to a 60-day lock that prevents you from transferring your domain name when you update the Organization field for the registrant contact, or when you update the First name and Last name fields for the registrant contact if an organization is not the legal registrant for your domain name.

NOTE: The 60-day lock does not apply to .au domain names. We send .au transfer-related information to the registrant contact’s email address as it displays in the Whois database.

Updating Contact Information for Domain Names with Privacy

When you add Private Registration to your domain names, Domains By Proxy® (DBP) hides your personal contact information from the public. In other words, DBP’s contact information replaces your personal contact information in the Whois database.

In your DBP account, you can update the your personal contact information and the underlying contact information for your domain names. You can have the same contact information for every domain name, or you can update the contact information for each domain name individually. When you update contact information in your DBP account, it remains hidden from the public.

You can also update your email forwarding preferences to determine how DBP sends information to you.
