5 is the Modulo-10 check character. The data to be printed becomes:

183145899385.

This same formula is used for EAN-13 (using the 1-12 digits) and EAN-8 (using the 1-7 digits).

UPC-E Checksum Calculation

Use the sample data of 123456 to demonstrate the UPC-E checksum calculation:

 The 6 digit UPC-E code is converted to a 10-digit code, using an expansion scheme based on the

sixth digit:

If the code

ends in:

UPC-E Data Insertion Digits Insertion

Position

10 digit code

0 abcde0 00000 3 ab00000cde

1 abcde1 10000 3 ab10000cde

2 abcde2 20000 3 ab20000cde

3 abcde3 00000 4 abc00000de

4 abcde4 00000 5 abcd00000e

5 abcde5 0000 6 abcde00005

6 abcde6 0000 6 abcde00006

7 abcde7 0000 6 abcde00007

8 abcde8 0000 6 abcde00008

9 abcde9 0000 6 abcde00009

Because the sample UPC-E code ends in a 6, the insertion digits 0000 are inserted at the sixth digit (insertion

position 6):

1234500006

 Add the Number System Character of 0 to the sample data:

01234500006

 Use the UPC-A check digit calculation described in the previous section to produce a check digit

as if it were a UPC-A code. The check digit for the sample data is:

 The complete 8 digit code consists of the Number System Character, the original 6 digit code and

the check digit:

01234565

1 2 ... 92 93 94 95 96 97 98 99 100 101 102 103
