Generate EAN-13 barcodes

What is EAN-13?

EAN-13 (European Article Number) is an international standard for product barcodes. It consists of 13 digits that uniquely identify products in retail and logistics.

How does EAN-13 work?

An EAN-13 code consists of:

• 3-4 digits for country code or special purpose
• 4-6 digits for manufacturer code (assigned by GS1)
• Product code (assigned by the manufacturer)
• 1 check digit calculated with a special algorithm

How is the check digit calculated?

The check digit for EAN-13 is calculated as follows:

1. Sum all digits in even positions (position 0, 2, 4, …)
2. Sum all digits in odd positions (position 1, 3, 5, …) and multiply by 3
3. Add the two sums together
4. Check digit = (10 - (sum % 10)) % 10

• 0-99: Internal company codes and special purposes
