Postal barcodes are machine-readable codes used by national and private postal systems to automate mail sorting and delivery. barKoder’s barcode SDK supports all major postal symbologies, enabling fast, accurate decoding for global mailing, logistics, and e-commerce applications.
Postal barcodes encode delivery routing information such as ZIP codes, destination points, and tracking numbers. They are designed for high-speed machine reading by automated mail sorting systems and are used across global postal networks.
Each country has its own format—some numeric, some alphanumeric—with unique encoding schemes and data capacities. These barcodes are optimized for high-density printing and fast decoding in logistics pipelines.
barKoder provides comprehensive support for widely used postal symbologies:
POSTNET - (United States USPS) Encodes ZIP, ZIP+4, and delivery point
PLANET - (United States USPS) Used for tracking outgoing/incoming mail
Intelligent Mail (IMb) - (United States USPS) Combines POSTNET and PLANET into a high-capacity hybrid format
RM4SCC - (United Kingdom Royal Mail) Encodes UK postal codes for fast mail sorting
Japan Post - (Japan) Encodes 7-digit postal codes and delivery info
KIX - (Netherlands) Used for automated sorting by Dutch Post
Australian Post - (Australia) Encodes delivery point, customer ID, and routing data
