H-4
Because the sample UPC-E code ends in a 6, the insertion digits 0000 are inserted
at the sixth digit (insertion position 6):
1234500006
2. Add the Number System Character of 0 to the sample data:
01234500006
3. 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:
5
4. The complete 8 digit code consists of the Number System Character, the

UPC-E Checksum Calculation
Use the sample data of 123456 to demonstrate the UPC-E checksum calculation:
1. The 6 digit UPC-E code is converted to a 10-digit code, using an expansion
scheme based on the sixth digit:
