Part 1: Why You Need to Keep Your Contact Information Up-to-Date

Have you received an email reminder from your registrar sometime in the past year, reminding you to review and update your contact information? You should have. This reminder email may be long and contain a lot of information, but it's important that you don't ignore it. It requires action on your part to review the contact information associated with your domain name and make corrections if necessary. It's important to keep your contact information up-to-date for a couple of reasons.

When your domain name registration is about to expire, the registrar is required to notify you. This is typically done via email. If your registrar is unable to reach you because your contact information is not up to date and your domain name registration expires, it may take considerable time and expenses to recover, or it may not be recoverable at all.

Another important reason to keep your contact information up to date is to ensure that you receive notifications from your registrar when changes are made to your domain name registration. These notifications are for your protection, so that you can verify and confirm the validity of the changes made, or take appropriate measures in the case of unauthorized changes. Bad actors can use malicious means to gain access to your account and make changes to the information associated with your domain name registration to lock you out of your account and hijack your domain name. It is important to keep your domain name registration contact information up to date to protect yourself or your business.

What Can Happen if Your Domain Name Contact Information is Not Kept Up-to-Date

If you give wrong information on purpose, or don't update your information promptly if there is a change, your registrar can suspend or even cancel your domain name registration. This could also happen if you don't respond to inquiries by your registrar if they contact you about the accuracy of your contact information.

How to Ensure Your Domain Name Contact Information Is Up-to-Date

If any of your contact information (email, postal address, phone number, etc.) changes, contact your registrar to update your information. The annual reminder email that you receive from your registrar is a requirement under the ICANN WHOIS Data Reminder Policy (WDRP), but do not wait for this reminder. If there's a change, it's important that you update your contact information as soon as possible to prevent disruption or loss of your domain name registration. ICANN cannot update your contact information for you; you must contact your registrar to do so. 

Due to the prevalence of security concerns such as phishing attacks, if you have any doubt or questions about the legitimacy of emails about your WHOIS data, you can always contact your registrar directly. If you believe you haven't been receiving reminder emails from your registrar, you can contact ICANN at

    Thank you for reading and for your questions. Regarding the question posted on 1 September 2017, no, this is not illegal. Some registrars offer privacy/proxy services for registrants, and these services may hide the data in certain WHOIS fields. Regarding the comment posted on 18 September 2017, this blog explains why it's important to keep your domain name contact information up-to-date. You should contact your registrar to update your contact information whenever there are changes.

    This is a useless notice and useless website. I'm supposed to verify the contact information for all of the domains I own, but there is no explanation or easy way to do that. Could you possibly make this more confusing?

    None of these reasons require you to make my personal information available to the entire internet. I'm an individual trying to register a domain name and you're asking me to make my name, address, email and phone number publicly available. By default only the registrar should need to know this info, I shouldn't have to pay for a yearly service to prevent my personal details from being revealed to the world. Many other service providers need to keep accurate information about their customers, but they don't go around making it public. In the early days of the internet this practice may not have been breaking any privacy laws (since there weren't any), but surely it should be reviewed now?

    Usted ha alcanzado un dominio que estaba pendiente por verificación acorde con las normas de ICANN, pero el dominio ya ha sido verificado. El sitio web pudiera tardar de 24 a 48 horas en estar disponible nuevamente en línea. nunca tuve acceso nuevamente a pesar que me dice que en 24 o 48 horas se establecera

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as"""" is not an IDN."
