NL-Alert is a Public Warning System in the Netherlands that warns and informs you about disasters. An NL-Alert message tells you what is going on, what you should do and where you can find more information.

You receive NL-Alert on your mobile phone. You can also see NL-Alert on a growing number of digital advertising displays and digital signs at train, bus, tram and metro stops.

When is NL-Alert used?

NL-Alert is used in harmful and life-threatening situations in the Netherlands, like a major fire, an epidemic or heavy weather. Do you see an NL-Alert? Read the message immediately, take action and help others.

Two times per year, the Dutch government sends an NL-Alert test message. The test message is sent on the first Monday of June and December at around 12.00 noon. This way, you know how NL-Alert looks and sounds when you receive an NL-Alert on your mobile phone. Due to a national holiday on Monday 6 June, the upcoming NL-Alert test message will be sent by the Dutch government on Monday 13 June 2022.

NL-Alert on your mobile phone

NL-Alert is based on cell broadcast technology. This technology is able to operate even in the event of phone network congestion or overload. NL-Alert is free and anonymous: you do not need to sign up and your phone number remains unknown.

NL-Alert on digital signage and advertising displays

You can see NL-Alert on a growing number of digital signs at train, bus, tram and metro stops. You will also see NL-Alert on more and more digital advertising displays. An NL-Alert is simultaneously displayed on signage and received on private mobile phones.
