Every Symbology
Fifteen symbologies, one fluent builder each. Two-dimensional matrices carry more data in less space; linear barcodes scan on older hardware and print narrower.
Every figure below is the symbol its page documents, generated from the code that page shows.

Choosing one
| You have | Use |
|---|---|
| a URL, or any text over ~20 characters | QR Code |
| a retail product number | EAN-13, or UPC-A in North America |

| anything else, alphanumeric | Code 128 |
-
Codabar Codabar, also known as NW-7, is a simple numeric-heavy barcode used by libraries, blood banks, labs, and older logistics workflows.
-
Code 128 Dense linear barcode over the full 7-bit ASCII range. Automatically picks code sets to keep numeric runs compact, and always appends its own checksum.
-
Code 39 Uppercase-only linear barcode, one of the oldest and simplest symbologies still in common use (inventory labels, ID badges).
-
Code 93 Higher-density successor to Code 39. It supports the same visible character set used here and always encodes the mandatory C/K check characters.
-
Data Matrix Compact square 2D symbol, ECC200 single-region only (10x10 to 26x26 modules).
-
EAN-13 The retail barcode printed on nearly every packaged product worldwide.
-
EAN-8 Compact retail barcode for small products. Give it 7 digits and the check digit is computed; give it 8 and the check digit is validated.
-
GS1 DataMatrix GS1 DataMatrix uses the same GS1 input contract as Gs1128, then renders an ECC200-style Data Matrix with the initial FNC1 codeword.
-
GS1-128 Code 128 profile for GS1 element strings.
-
ISBN Book identifiers, rendered as their EAN-13 "bookland" barcode.
-
ITF-14 Logistics barcode for GTIN-14 shipping containers. It is built on Interleaved 2 of 5 and renders bearer bars by default.
-
Interleaved 2 of 5 Dense numeric-only barcode for warehouse, industrial, and distribution workflows. It encodes digits in pairs, so the input length must be even.
-
QR Code The most recognizable 2D symbol.
-
UPC-A Retail barcode used heavily in North America. Give it 11 digits and the check digit is computed; give it 12 and the check digit is validated.
-
UPC-E Zero-compressed UPC for small packaging. It accepts the 6-digit payload, 7 digits with number system, or the full 8 digits with check digit.
