What is the Residents' Registration Office and why do I have to register there?

When you move to a new address in the Netherlands, you must register your new address with your local municipality (gemeente) within five days of moving. Failing to do so may result in a fine. An incorrect address registration can also affect important matters such as your taxes and government benefits.
So, how do you register your new address in the Netherlands? Read on to learn the process, or visit your municipality's website for more information (available in Dutch).
