GTIN instructions

Generate a list of 1,000 Global Trade Item Numbers (GTIN) from the 9-digit master number. Free, no registration required.

1. Enter the 9-digit master number (GS1 company prefix) and click Go!
2. GTINapp generates 1,000 GTINs by adding 3-digit item references (000 to 999) to the master number. A check digit is calculated for each GTIN (Luhn algorithm, modulo 10). The resulting 1,000 complete, 13-digit GTINs are written to a text file.
3. Download the text file, done!

Barcode instructions

After entering the first 10 digits, you can create 100 barcodes. 2-digit article references (00 to 99) are added to the first 10 digits. A check digit is calculated for each GTIN (Luhn algorithm, modulo 10). Barcodes are then generated from the complete 13-digit GTINs.

1. Enter the 10-digit number and click Go!
2. GTINapp generates 100 barcodes as GIF images and packs them into a ZIP file.
3. Download the ZIP file, done!

To generate 1,000 barcodes, you must repeat the process 10 times, e.g.: 12345678901, 12345678902, 12345678903. As a result, you will get 100 barcodes each time.
