Depending on your environment you can either use GNU barcode: http://www.gnu.org/directory/barcode.html or write your own routines. If you just need numbers there is an easy code named 2 of 5 interleaved. You can find a description of the various coding systems at: http://www.barcode-1.net/pub/russadam/info.html#Specs But I definitely recommend using code 128, because it can hold any type of character and has a check digit calculation included avoiding reading errors (in contrary to the above mentioned code). But implementation is more difficult. Hope this helps.
