Postal Barcode Scanning for Mail & Logistics

What Are Postal Barcodes?

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.
