The allocation of the GTIN-8 format is restricted to items that cannot accommodate an EAN-13 or
UPC-A barcode, for example a lipstick or a box of matches. They consist of 8 digits and so the barcode is smaller in size. GTIN-8 are issued individually by GS1 Member Organisations and is authorised when the following conditions apply:

• The total printable area of the product packaging is less than 80 cm²
• The area of the largest label for the item is less than 40 cm²
• The product is cylindrical with a diameter less than 30 mm.

Before deciding to use a GTIN-8 format, the user should first consider all possible options for using a GTIN-13 format. These may include

• Whether the symbol can be reduced in size, i.e. printed at a lower magnification, taking into
  account the minimum barcode print quality requirements.
• Whether the package artwork or the label design can reasonably be changed, to enable the printer's recommended size of standard EAN/UPC symbol to be included.
• Whether a truncated symbol can be used. A truncated symbol (a symbol of normal length, but
  of reduced height) may only be used if there is absolutely no possibility of printing a symbol in
  full size

A GTIN-8 is issued individually by GS1 and matched to a single product intended to be sold as a retail unit

A GTIN-8 begins with the three numbers of the country prefix and ends with the last number which is the check digit. The structure doesn’t acquire any type of management since the GTIN-8 is used as attributed by GS1.

A GTIN-8 is global and independent from the country of origin and trafficking of the product. Its validity is ensured by the service Verified by GS1, where product information is available.

GTIN-8 is depicted by an EAN-8 symbol.
