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  • The details registered about me/my company are incorrect or out of date.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

Join SIDN at the Dutch Open Hackathon

  • Friday 23 March 2018

For the fourth time Dutch Open Hackathon takes place at the inspiring Dutch Innovation Factory in Zoetermeer on 26 and 27 May! We challenge our registrars to enter and join a team of SIDN experts. Spend a weekend with other developers and creatives getting to grips with challenges that set your mind racing -- helped by a range of unique datasets, APIs and hardware made available by five of the Netherlands' key organisations: Kadaster, KPN, the National Police, PostNL and SIDN.

Great prizes for coming up with creative applications

Take on the challenge of coming up with applications and creative solutions for practical, everyday issues, and you could win a great prize, such as incubation for your project and a tasty cash award. Give open innovation a boost and devote your brainpower to developing digital services that will have a positive impact on everyday life for consumers and organisations. How can people and organisations safely benefit from the Internet of Things? How can you make homes smarter without making them vulnerable? How can businesses interact without risking sensitive information leaks? How can we use technology to make everyday life more convenient and more secure? Experts from the five host organisations will be at the Hackathon to help you think through your ideas.

Enter the hackathon in a joint team of registrars and SIDN

Accept the challenge and enter the hackathon in a joint team of registrars and SIDN. Register now by sending an email to communicatie@sidn.nl. You can develop a completely new project or idea, or refine something that's already out there. Each team can have up to six members. We aim for two mixed teams of registrars and SIDN experts.

Party on!

As at the three previous Hackathons, participants will want for nothing. Great food, comfortable workstations, cosy sleeping cabins and plenty of scope for simply hanging out. Not to mention a celebratory drink on Sunday evening. And of course all kinds of cool gadgets. Tot 26 en 27 mei!
