It is universally supported by barcode scanners, POS systems and inventory software worldwide — making it one of the most versatile barcode formats available.

Our tool supports Code 128, which is one of the most versatile barcode formats. Here is a clear comparison to help you understand why Code 128 is often the best choice:
| Feature | ▤ Code 128 | UPC / EAN | Code 39 |
|---|---|---|---|
| Supports text & numbers | ✅ Yes | ❌ Numbers only | ✅ Yes |
| High data density | ✅ Yes | ❌ Limited | ❌ Lower |
| Universal scanner support | ✅ Yes | ✅ Yes | ✅ Yes |
| Best for logistics | ✅ Yes | ❌ No | ❌ No |
| Best for retail | ✅ Yes | ✅ Yes | ❌ Less common |
Use Code 128 when you need to encode both text and numbers with high accuracy. Use UPC/EAN for retail product IDs. Use Code 39 for simple alphanumeric encoding where density is less critical.
Always type the exact text or number you want to encode. Typos will appear exactly as entered.
Set barcode height and width according to your printing needs. Larger sizes scan more reliably.
Use dark bars on a light background. Low contrast barcodes are harder to scan.
Always scan your barcode with a reader or phone app before bulk printing to ensure accuracy.
