Frequently asked questions

  • I am looking for a domain name registrant. Where can I look it up?

    The Whois is an easy-to-use tool for checking the availability of a .nl domain name. If the domain name is already taken, you can see who has registered it.

    On the page looking up a domain name you will find more information about what a domain name is, how the Whois works and how the privacy of personal data is protected. Alternatively, you can go straight to look for a domain name via the Whois.

  • I would like to transfer my domain name to another registrar. What is the procedure?

    To get your domain name transferred, you need the token (unique ID number) for your domain name. Your existing registrar has the token and is obliged to give it to you within five days, if you ask for it. The procedure for changing your registrar is described on the page transferring your domain name.

  • The details registered about me/my company are incorrect or out of date. How can I get them updated?

    To update the contact details associated with your domain name, you need to contact your registrar. Read more about updating contact details.

  • Why is my domain name in quarantine?

    When a domain name is cancelled, we aren't told the reason, so we can't tell you. You'll need to ask your registrar. The advantage of quarantine is that, if a name's cancelled by mistake, you can always get it back.

    One common reason is that the contract between you and your registrar says you've got to renew the registration every year. If you haven't set up automatic renewal and you don't renew manually, the registration will expire.

  • Ik heb een klacht over mijn provider/registrar. Kan ik daarvoor bij SIDN terecht?

    Wanneer je een klacht hebt over of een geschil met je registrar dan zijn er verschillende mogelijkheden om tot een oplossing te komen. Hierover lees je meer op pagina klacht over registrar. SIDN heeft geen formele klachtenprocedure voor het behandelen van een klacht over jouw registrar.

  • What conditions do I have to meet as a registrar?

    Would you like to be able to register domain names for customers or for your own organisation by dealing directly with SIDN? If so, you can become a .nl registrar. Read more about the conditions and how to apply for registrar status on the page becoming a registrar.

SIDN BrandGuard update Q3 2023

Don't forget to enable 2FA!

  • Wednesday 27 September 2023

We're constantly working to make SIDN BrandGuard even better. Many enhancements are made in response to user input. Over the summer, the focus has been on refining the user interface, logo detection and interface security. The main improvements we've made are described below.

API documentation in the web portal

Users have often been getting in touch with questions about using the API. We've therefore made documentation available from the portal, explaining how to connect to the SIDN BrandGuard API.

Bug fixes

In recent weeks, 2 bugs have been fixed. Sorting results by administrative contact is now working properly again, enabling efficient identification on the basis of contact details. Moving results in bulk (i.e. >1,000 results) is now issue-free as well.

Lots happening in the background

Much of our continuous enhancement work isn't immediately visible to users. For example, we've made a number of technical improvements that will simplify signing on in the future and make the application easier to maintain.

Enable 2FA

We'd like to remind you about 2-factor authentication. Use of a second identification factor for signing on considerably reduces the risk of unauthorised access to the application. For the moment, 2FA remains optional, but it's mandatory from 1 October 2023. We therefore recommend enabling it now.
