Coupon Coding

1. Coupon Types

There are two different types of coupon codes; one for coupons denominated in Euro and a second for coupons issued in Sterling (GBP).

The Euro Coupon GTIN
A common GTIN structure has been developed for use on coupons throughout the Eurozone.  If you wish to bar code a money off voucher you will need a special Company Prefix Number starting with the digits 981 or 982, to be allocated to you. As with variable weight retail units, these GTINs encode the value of the discount within them.

The Sterling (GBP) Coupon GTIN
A separate prefix and coding structure is used for GTINs to identify coupons denominated in Sterling. If you wish to apply bar codes to coupons for use in the UK market, you will need to apply for a prefix commencing with the digits 99.

2. Coupon Code Structure

981 or 982: Euro coupon prefix which denotes position of decimal place in value field i.e. 982 indicates two decimal places.

XXXX: Coupon Issuer Number - these four digits plus the 981/982 prefix make up the seven digits which identify your company as the unique holder of this issuer number.

NN is the coupon promotion reference number. The reference numbers run from 00 to 99 enabling you to allocate up to 100 promotion references from any one prefix.

VVV is the three digit value field. For example if the coupon redemption value is 50 c VVV=050. Redemption values from 1c to € 9.99 should be represented with the prefix 982 and by three value digits from 001 to 999. For values greater than €10 use the prefix 981 and the value in 10 cent blocks from 10.0 to 99.9. Coupons for free goods should have a zero value (VVV=000).

C is the check digit calculated in line with the standard modulo 10 algorithm.
