Help! How do I get started with ISBN-13 barcodes?
The first step in making an ISBN-13 barcode is to obtain your ISBN number or numbers. You'll need one ISBN number for each one of your book or book products. The ISBN standards body, Bowker, is your very first stop.
Once you've got ISBN numbers you're ready to turn them into ISBN-13 barcodes, which you can print onto labels or incorporate into your book jacket or product packaging design. Retailers will ask you for each product's ISBN-13 information, so be sure to maintain an ISBN database or spreadsheet for yourself, and back it up frequently.return to top
How do I calculate an ISBN-13 check digit?
Like the UPC check digit, an ISBN-13 check digit is calculated like an EAN-13 symbol using a mod 10 calculation. The last digit in an ISBN13 barcode is a check digit based on the previous 12 numbers. Our example barcode data is "978123456789".
Add the digits in the even-numbered positions (first, third, fifth, etc.) together.9+8+2+4+6+8=37
Multiply that number by three.37x3 = 111
Add the digits in the even-numbered positions (second, fourth, sixth, etc.) to the result.7+1+3+5+7+9=32
Find the resulting modulo 10 (the number that when added will make the next multiple of 10).111+32=143 (the next multiple of 10 is 150)
143+7 = 150
7 is the check digit. return to top

What is an ISBN-13 barcode?
International Standard Book Numbers are distributed by the ISBN standards body.
An ISBN-13 barcode consists of guard bars, the 12-digit book number, a check digit, and human-readable digits printed below the bars. There is often an additional barcode to the right of the ISBN-13 called a 'supplemental'. The supplemental is a five digit barcode that contains the book (or book product) price. ISBN-13 bar codes are numbers-only, have a fixed length, and should be printed in black against a white background for ease in scanning.
Once you receive your ISBN/s from the standards body, you're ready to use Azalea's UPCTools to turn your ISBN numbers into ISBN barcodes. return to top
the best way to share my ISBN-13s?
If you use UPCTools to make an ISBN-13 barcode, simply paste the barcode into any document, labeling or design application, save as high-quality PDF document, then email. File formats like JPG and GIF are bitmapped formats and don't have the resolution necessary to make scannable symbols. Give 'em a PDF file. Create, copy, paste, save, send. Done! return to top
