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  • The details registered about me/my company are incorrect or out of date.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

Frontend is getting an important update, and 2FA is coming soon

  • Thursday 10 October 2024

Our Secure Domains team is constantly working on improvements for SIDN BrandGuard users. The latest product of their efforts is a major update to the system's frontend, which will be rolled out very shortly. The main benefits will be important but largely invisible technical improvements, such as big fixes and solutions to problems with certain browsers. Testing of the update is currently nearing completion.

Whitelist-based access control is ending

A number of BrandGuard subscribers have told us that they'd like an alternative to the existing system of access control based on IP whitelisting. So we're going over to a 2-factor authentication (2FA) system, which will mean that subscribers don't need to have their IP addresses added to a whitelist in order to access the service.

2FA is coming soon

When 2FA comes in, subscribers will be able to secure their accounts using apps such as Google Authenticator of Microsoft Authenticator. Secure access to SIDN BrandGuard will then be possible from any location, improving both convenience and security.

Are you an SIDN BrandGuard user with a question about the changes described here? You can reach us on working days between 8:30am and 5pm (Dutch time) by calling +31 26 352 5555 or mailing support@sidn.nl.
