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  • The details registered about me/my company are incorrect or out of date.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.

Come to SIDN Inspire at the ECP Annual Festival

Two organisations, one event

Kom naar SIDN Inspire tijdens ECP Jaarfestival
  • Tuesday 1 July 2025

What began as SIDN Contact Day, became SIDN Connect and then SIDN Inspire will continue in November at the ECP Annual Festival. SIDN and ECP have always collaborated successfully in a variety of fields, with each of us organising an annual event of our own. SIDN is also a longstanding partner of the ECP’s Annual Festival. Now, with the aim of increasing the reach of the 2 separate events, we’ve decided to start a new chapter in our partnership in November. As of this year, the ECP Annual Festival will be a joint ECP-SIDN promotion. Our 2 organisations will have a single successful, unified event for inspiring our contacts and cementing relationships in the interests of a stronger digital community.

Save the date

This year’s ECP Annual Festival is on 20 November, at the Fokker Terminal in The Hague.

It’s theme is: Consciously digital! Self-aware. Purpose-aware. Future-aware.

How aware are we of the digital world that we’re constantly shaping?

In an era when technology has a profound influence on everyday life, awareness of the digital choices we make is more important than ever. How do we build a resilient society, in which technology is not only smart and innovative, but also ethical, fair, secure and inclusive?

Formal event invitations will go out in September.

Registrars-only pre-programme

The programme for the ECP Annual Festival is still taking shape, but it’ll follow the traditional format of a plenary gathering followed by numerous parallel sessions for attendees to choose from. SIDN will deliver 3 of those sessions. You’ll be able to say which ones you want to attend when you register. Between the sessions there’ll be ample networking opportunities.

And, before the main proceedings, we’re hosting a special registrars-only pre-programme for .nl registrars. The pre-programme reception is from 9:30 to 10:00 am. Then, from 10:00 to 11:00, we’ll be sharing all the latest news about developments at SIDN and in the domain name market. Details of the topics to be covered will be given closer to the day.

Will we see you there?

Block out 20 November in your diary for the opportunity to experience an unforgettable day of inspiration and new insights. An event you don't want to miss!
