KIX Code - Dynamsoft Barcode Reader SDK

The KIX (Klant Index) barcode is a specialized barcode symbology used primarily by PostNL, the national postal service of the Netherlands. It is a variant of the Royal Mail 4-State Customer Code (RM4SCC) and is designed for encoding postal information, such as delivery addresses, in a compact format.

Specifications

  • Character Set: Uppercase letters (A-Z) and digits (0-9)
  • Length: Variable (typically 12-14 characters for Dutch postal codes and house numbers)
  • Structure: Uses a four-state encoding system
  • Format: A typical KIX barcode represents a Dutch postal code (four digits + two letters), a house number and an optional house number addition

The KIX barcode uses a 4-state encoding system, meaning each character is represented by a combination of four types of bars: ascender, descender, full bar, and tracker, and the barcode is read from left to right.

Check Digit Calculation

The check digit is calculated using a weighted sum algorithm. Each character in the barcode is assigned a weight, and the sum of the weighted values is used to determine the check digit. This ensures that the barcode can be validated for accuracy during scanning.

Where is KIX Barcode used?

The primary application of the KIX barcode is by PostNL, particularly for automated mail sorting and delivery address encoding.
