## UPC and EAN

UPC is common in North America, EAN in most other markets. Both are GTINs.

## When you need official GS1 codes

Large retailers and marketplaces check codes against the GS1 registry. Internal codes are fine for your own POS.

## Printing labels

Match label size to your printer and test-scan a few before printing hundreds.
