Frequently Asked Questions

What is Code 128?

Code 128 is a high-density linear barcode symbology that can encode all 128 ASCII characters. It's widely used in shipping, packaging, and inventory management. Code 128 offers excellent density and reliability, making it suitable for encoding alphanumeric data like product IDs, serial numbers, and tracking codes.

How do I ensure my barcode will scan correctly?

For reliable scanning, ensure adequate quiet zones (white space) on both sides of the barcode, use sufficient height, and print at high resolution. Test with your intended scanner before mass production. Avoid stretching the barcode too wide or printing too small. The human-readable text below helps verify the encoded data.

What can I encode in a Code 128 barcode?

Code 128 can encode all standard ASCII characters including uppercase letters, lowercase letters, numbers, and special characters. This makes it versatile for various applications like product SKUs, asset tags, shipping labels, and inventory tracking. However, the more characters you encode, the wider the barcode becomes.
