Postal barcodes are essential tools in the global mailing system. They streamline sorting, tracking, and delivery by encoding key addresses or routing information directly onto mailpieces. However, with numerous regional formats—such as IMb, RM4SCC, and KIX—finding a reliable postal barcode generator that handles them all can be challenging.
Introducing our new user-friendly barcode maker - completely free. Effortlessly create professional postal barcodes for direct mail promotions, supply chain operations, and online order fulfillment.
What Is a Postal Barcode?
A postal barcode is a machine-readable symbol printed on mail items to assist postal services with sorting and delivery. These barcodes encode information such as postal codes, delivery points, and tracking numbers. By automating mail handling, postal barcodes reduce human error and speed up delivery.
Most countries have their own standards for postal barcodes, which makes international mail handling more complex without the right tools.
Popular Postal Barcode Types
1. IMb (Intelligent Mail Barcode)
The IMb is the current standard used by the USPS. It combines data from older barcodes like POSTNET and PLANET into a single, high-density 65-bar symbol. USPS IMb supports advanced mail tracking, delivery point validation, and automation of large-volume mail processing.
2. RM4SCC
Royal Mail uses the RM4SCC (Royal Mail 4-State Customer Code) to encode address information for automated sorting. The barcode uses four vertical states for each character and is often printed on letters and large-volume mailings.
3. KIX
KIX (Klantindex) is the Dutch postal barcode format used by PostNL. It simplifies address encoding by directly representing the postal code and house number in a compact barcode.
4. Australia Post Barcode
This 4-state barcode format supports multiple encoding modes, including Standard Customer and Customer Barcode. It's widely used across Australia for high-volume business mail—particularly in billing, government communications, and e-commerce logistics.
5. Japan Post 4-State Customer Code
This barcode format is used to automate mail sorting and delivery in Japan. It encodes address and routing data with four bar positions per character, enabling fast, accurate processing—ideal for businesses handling direct mail or e-commerce shipping within Japan's postal system.
Why a Versatile Postal Barcode Generator Matters
Most free barcode tools only support basic linear or 2D formats, and very few allow users to generate postal barcodes like IMb or RM4SCC without complex setup or software installation. If you're dealing with cross-border mail, e-commerce shipping, or multi-country operations, flexibility is key.
Our postal barcode generator (https://www.onlinetoolcenter.com/) online stands out by supporting a wide range of international postal codes in one place. No downloads. No fees. No technical barriers.
