How do Dutch number plates work?

How do you read a Netherlands number plate?

These plates are issued in sequence 1 and 3 with 1 instead of 2 characters. The character indicates the province the license plate was issued: A=Friesland, E=Groningen/Drente, H=Overijssel, K=Noord-Holland, L=Zuid-Holland, N=Zeeland, P=Utrecht, S=Gelderland, T=Noord-Brabant and V=Limburg.

What does a green number plate mean in the Netherlands?

Most number plates are yellow but some use other colours to indicate their use. Taxis are blue, and a bright green number plate indicates the car is being driven by a dealer. Not every vehicle on the Dutch roads has to have a licence plate – at the moment at least.

Why do some countries have yellow license plates?

Yellow registration plates are used both front and rear in Luxembourg and the Netherlands. Denmark and Hungary use yellow plates for vehicles registered as commercial vehicles. Denmark implemented the EU format on a voluntary basis in 2009. Danish plates have a small holographic strip to the right of the blue EU strip.
