Everything you never 
wanted to know about barcodes

Welcome

Compiled by Nick Johnson.

Welcome to my barcode specifications site. Here I have gathered specifications for various barcode types that I have extrapolated from web documents, gathering together lots of barcodes for analysis, and being generally clever. If you know of any mistakes in the data presented here, please email me.

Please visit our sponsors by clicking on the banner above; this will help to offset the costs of presenting this site.

Each of the barcode specifications is accompanied by a web interface that allows you to interactively create your own barcodes to your liking.

5/4/2000:Updated spec to code 3 of 9 to mention both modes
3/3/2000:Added spec for the barcode found on the Dutch Guilder notes
1/26/2000:Corrected checksum problem in Postnet CGI, added verbage to the spec page about Bulk Rate Postnet barcodes.
11/28/1999:Corrected one bad pattern in the Code 16k spec.
Barcodes for UPC, Code 3 of 9, Interleaved 2 of 5, and Codabar have been verified to scan properly. Thanks goes to aard for verification

UPC UPC - ubiquitous to products in stores everywhere
Postnet Postnet - go Postal; now includes envelope generator!
Code39 Code 3 of 9 - inventory tracking, etc.
Interleaved 2 of 5 Interleaved 2 of 5 - distribution industry, game tickets
