NL — Netherlands

The Netherlands is a Western European country known for its flat landscape, canals, windmills, tulips, and cycling culture. Amsterdam is the constitutional capital, while The Hague is the seat of government — a dual-capital distinction important for databases. The Netherlands is one of Europe's most digitally advanced nations and a founding EU member. The Euro is the currency. For developers, the NL country code maps to the nl-NL locale for Dutch. The .nl domain is one of the most registered ccTLDs in Europe, and +31 is the dialing code. Dutch number formatting uses comma for decimals and period for thousands. The Netherlands' dual-capital system (Amsterdam vs The Hague) and the distinction between 'The Netherlands' (NL) and 'Holland' (which technically refers to only two provinces) are common data quality issues. The BSN (Burgerservicenummer) citizen service number has specific validation. The Netherlands hosts the AMS-IX, one of the world's largest internet exchange points, and many European data centers.
