The GTIN digits are shown as a barcode – e.g. as EAN-13 (GTIN-13) or UPC-A (GTIN-12). For outer cases, ITF-14 (GTIN-14) is common.
Where do I get a GTIN?
Official GTINs for retail come from GS1 (e.g. your national GS1 office). For internal use, samples or tests you can turn your own numbers into a barcode with the GTIN generator.

FAQ
Is GTIN the same as EAN?
EAN-13 is a 13-digit GTIN. GTIN is the umbrella term; EAN/UPC/ITF-14 are concrete formats.
Are self-generated GTINs valid in retail?
No. For public sale you need an official GS1 number. Self-generated codes are only suitable for internal use.
