Barcodes are essential in modern business, from tracking inventory in stores to managing shipments.
However, choosing the right barcode type and understanding its encoding rules can be tricky.
This guide will explain the basics of barcode encoding and help you select the most suitable barcode for your needs.
What Are Barcode Encoding Rules?
Barcode encoding rules are the standards that convert data (numbers, letters, or symbols) into a machine-readable barcode.
Each barcode type follows its own encoding system based on the type and length of data being encoded. These rules ensure the data can be accurately scanned and processed.
Common Barcode Types and Their Uses
1. Numeric Barcodes: EAN-13 & UPC-A
These barcodes are ideal for products that only contain numeric data.
EAN-13 is a 13-digit barcode used worldwide, especially for retail products.
UPC-A is a 12-digit barcode commonly used in the U.S. retail industry.
When to use:
Retail product identification
International shipping and tracking
2. Alphanumeric Barcodes: Code 39 & Code 128
These barcodes support both numbers and letters, making them more versatile than numeric barcodes.
Code 39 is widely used for simple data encoding and supports uppercase letters, numbers, and some symbols.
Code 128 supports all ASCII characters and is known for its high density, allowing more data to fit in the same space.
When to use:
Inventory management
Asset tracking
Warehouse labeling
3. 2D Barcodes: QR Code & Data Matrix
When you need to encode large amounts of data, 2D barcodes are the best choice.
QR Code can store a variety of data types, including text, URLs, and images.
Data Matrix is often used for small labels and can store more data in a smaller space, making it ideal for electronics and medical devices.
When to use:
Encoding large amounts of data
Mobile marketing and product verification
Electronics and medical equipment labeling
How to Choose the Right Barcode Type?
When selecting a barcode, consider the following factors:
1. Data Type:
For numbers only, choose EAN-13 or UPC-A.
For letters and numbers, go with Code 39 or Code 128.
For complex or large data, opt for QR Code or Data Matrix.
2. Data Length:
For short data, use Code 39 or ITF.
For longer data, Code 128 or QR Code are better options.
3. Application & Compatibility:
Ensure the barcode type is compatible with your scanning equipment.
If you need small labels, consider Data Matrix.
