Chapter 11 Data Formats of Barcode Types

UPCA

11 numbers are transferred for the UPCA code. The 12. digit represents the check number. The even figures of the information have a factor of "3", the uneven figures a factor of "1". Counting begins from the left. The resulting cross sum is divided by 10. The remaining figure is subtracted from the modul (10). If the remainder is "0", the check number is also "0".

Example

Information	4	0		1		2		3	4	5	6	7	8	9	3
Factor	3	1		3		1		3	1	3	1	3	1	3
Product	12 +	0	+	3	+	2	+	9	+ 4	+ 15 +	6	+ 21 +	8	+ 27
Cross sum	107

10 (modul) - 7 (remainder) = 3 (check number)

For remainder “0” the check number is also “0”.

UPCE

For the UPCE barcode type, seven numbers are transmitted. The 8. digit is the check number. The uneven figures of the information have a factor of "3", the even figures a factor of "1". Counting begins from the left and the resulting cross sum is divided by 10. The remaining integer value is subtracted from the modul (10). The result is transmitted as the check number (c).

Example

Information	0		1	2	3	4	5	6	5
Factor	3		1	3	1	3	1	3
Product	0	+	1	+ 6	+ 3	+ 12 +	5	+ 18
Cross sum	45

10 (modul) - 5 (remainder) = 5 (check number)

For remainder “0” the check number is also “0”.
