Postal codes in Belgium consist of four digits, with the first digit representing one of ten postal regions. The remaining three digits specify the exact post office or delivery area. Postal codes were introduced in Belgium in 1969 and have since become an essential component of efficient mail delivery. For example, the postal code for Brussels, the capital city, is 1000, with the first digit (1) representing the postal region and the remaining three digits identifying the specific delivery area. Postal codes are widely used in Belgium and are required when addressing letters and packages for delivery.
