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  • The details registered about me/my company are incorrect or out of date.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 Q1 2024

Chrome and Safari user experience now improved

  • Thursday 11 April 2024

Over the last 6 months, we've invested heavily in improving the algorithm underpinning SIDN BrandGuard's logo detection module. The improvements mean that logo abuses are detected sooner, and fewer false positives are shown on the interface. Many of the enhancements came in last year, but we've continued to roll out upgrades in the first quarter of this year. The changes were realised in close consultation with a small number of active users.

Bug fixes

One thing we've done is fix a number of problems with the user interface. The issues included graphical bugs affecting Chrome and Safari users, which made the interface less user-friendly. The latest version of SIDN BrandGuard, incorporating the changes, will be launched in the near future.

New data platform

We're currently busy working on a new data platform for international domains. Once it's up and running, we expect to be able to flag up domain names with extensions other than .nl much more quickly.
