PostNL manages the highly efficient alphanumeric Postcode system in the Netherlands, a network known for its extreme precision. The system was implemented in 1977 to allow for automated sorting down to specific street segments and even individual sides of a street. This level of granularity is essential for the Dutch logistics sector, which supports one of Europe's busiest international trade hubs.
The Dutch Postcode consists of four digits followed by a space and two capital letters. The digits indicate the town or district, while the two letters identify the specific street or a range of house numbers.
