Marking consumer packages
Items which are handled at a store’s checkout are barcoded so that the item number can be quickly and easily read. Using the item number, prices and the item name are fetched from the store’s article database and printed on the receipt. The item number is also a requirement for collecting reliable sales statistics for, for example, purchasing decisions, profitability follow-up and shelf space planning.
Item numbers and barcodes for consumer packages
Consumer packages are numbered with a Global Trade Item Number (GTIN) or a variable measure number and barcoded using EAN‑13 or EAN‑8.
- GTIN‑13 is the most common number for consumer packages and is encoded using an EAN‑13 barcode. To create the number you need a GS1 Company Prefix.
- Consumer packages with variable weight, such as meat, fish or cheese, are numbered with a national variable measure number which is encoded using an EAN‑13 barcode. To create a variable measure number you need a GS1 Variable Measure Prefix.
- Small items with limited space for a barcode can, in exceptional cases, be numbered with a GTIN‑8 and this number is encoded using an EAN‑8 barcode. To create a GTIN‑8 number you need a special GS1‑8 Prefix.
