How to Calculate Check Digit Online?
Check digit calculator :
Check Digit :
The last digit of a bar code number is a computer Check Digit which makes sure the bar code is correctly composed.

GS1 Company Prefix (GCP) :
GCP is a part of the GS1 Identification number consisting of a GS1 Prefix and a Company Number, both of which are allocated by GS1 Organisations. GS1 India assigns GCP to its subscribers who administer the allocation of GS1 Identification numbers.

Item ID :
The GS1 subscribers allocate unique item ID for each item/product variant/ SKUs.

Check Digit calculation :
Check digit is calculated by using the digits present in GCP and Item ID parts of a GS1 identification number. This calculation, called the Modulo 10 algorithm, is same for all GS1 primary identification numbers.

Every time a computer decodes a GS1 barcode number it repeats the calculation and checks its answer against the check digit to verify the data integrity of the number.
