Barcodes Explained: Which Type Do You Need?
Why So Many Barcode Types?
Different industries have different needs. A retail product needs a universal code that works everywhere, while an internal warehouse might use custom codes for efficiency.
Common Barcode Types
- UPC-A (12 digits): Standard for North American retail products.
- EAN-13 (13 digits): International retail standard, compatible with UPC.
- Code 128: Alphanumeric, used in shipping and logistics.
- Code 39: Letters and numbers, common in automotive and defense.
- QR Code: 2D code storing URLs, text, or data up to 4,296 characters.
1D vs 2D Barcodes
1D (Linear): Traditional "lines" barcodes. Store limited data (typically 20-25 characters).
2D (Matrix): QR codes, Data Matrix. Store much more data and can be read even when partially damaged.
Choosing the Right Type
- Retail products: UPC-A (US) or EAN-13 (international)
- Shipping labels: Code 128
- Marketing/URLs: QR Code
- Internal tracking: Code 39 or Code 128
