Depends on the barcode standard you're going to use.  Some of the
standards have checksums and internal algorithms to validate the
number, and probably wouldn't work for what you want to do.

Barcode3 of 9 is a simple representation of the numerals in black bar
format, and might suit what you need, but doesnt require the checksums
etc.   For Barcode3of9 all you need is to get the truetype font (or
Adobe format if you prefer) and print out your number in the barcode
font in the spreadsheet.     For most of the other barcode formats
(for example the ones used on goods in supermarkets or on CDs)  you
have to make sure the checksum is correctly calculated or no reader
will recognise it.

Best to read up on barcode standards first, to check the terminology
used, so you understand which of the formats will suit what you need.
Then go find a font to suit.   You will need to make sure your users
have that font installed on their PCs or they'll only see the arabic
numerals.

You get nothing for nothing however.   Barcode3of9 is really easy to
output, because all your ColdFusion is going to have to do is output
123465 and display in the correct font.  But because it doesnt have
the checksums to validate the code, the read accuracy is lower and the
read error count is higher. (which is why the checksums were
inrtroduced in the first place of course)

Some barcode scanners have a setting so you can tell ilt what code
standard it's going to read, and some detect the kind of code
automatically.

HTH.
