Like UPCA, UPCE is linear barcode symbology of the EAN/UPC symbology family. UPCE is the zerosuppression version of UPCA barcode. Length of UPCE (6 digits) barcode is approximately half of UPCA (12 digits). It is widely implemented in small packing labels since it allows for compaction of unnecessary zeros and save the spaces. Message length will be 7 or 8 characters long depending on the checksum digit mode. The first digit of the UPCA barcode should be zero or one depends on the length of message.
Structure of the UPC E
UPCE barcode has physical and logical Structure. The Physical structure of barcode UPCE reading from left to right contains:
 A left Quiet Zone
 A normal lefthand Guard Bar Pattern, or start sentinel.
 Six data characters from number sets A and B encoded from the parity table.
 A special right hand Guard Bar Pattern
 A right Quiet Zone
Logical Structure of a UPCE, do not include the Quiet Zone
Guard bar pattern Six symbol characters Special guard bar pattern
3 modules 6*7 = 42 modules 6 modules
The total modules will be 3 modules +42 modules+6 modules=51 modules
Usually UPC E barcodes encodes 6 numerical digits. And A twodigit AddOn Symbol or fivedigit AddOn Symbol may be used in an UPCE barcode. They are used to encode information supplementary of the barcode. Thus UPCE supplement 2 (2digit Addon) or UPCE supplement 5 (5digit Addon) is obtained. The addon digit symbol should be appended following the right Quiet Zone of UPCE barcode. When length of the UPC E digits is 6, leading digit is "0" and check digit is not included. When length of the UPC E digits is 7 or 8, leading digit could be "0" or "1" and check digit is not included.
Encoded Data of UPCE
UPCA encodes digits of numeric numbers from 0 to 9.
Checksum Digit of UPCE
The checksum digit is necessary verifying the barcode. Like UPCE, the checksum digit is calculated based on the Mod10 standards. The Mod10 method is utilized for verification of barcode as: UPCA, UPCE, EAN13 and EAN8.
 Choose the right most digits as the odd position digit, and put it into the right most column.
 Assigned the following digits from right to left in sequence from odd to even position.
 Multiple all value in odd position with 3. And calculation all the summaries of the result.
 Put an number to add with the result and let it be even divided by 10. The number added is the checksum digit.
 Details please refer to the calculation steps of UPCA.
CONVERTING A UPCA CODE TO UPCE
If the ending code of manufacturer code (the last three digits) ends of the numbers of 000, 100, or 200, the product code should be 1000 numbers from 00000 to 00999.
If the ending code of manufacturer code (the last three digits) ends of the numbers of 300, 400, 500, 600, 700, 800, or 900, the product code should be 100 numbers from 00000 to 00099 .
If the ending code of manufacturer code (the last two digits) ends of the numbers of 10, 20, 30, 40, 50, 60, 70, 80, or 90, the product code should be 10 numbers from 00000 to 00009.
If the ending code of manufacturer code (the last two digits) ends of the numbers of 10, 20, 30, 40, 50, 60, 70, 80, or 90, the product code should be 10 numbers from 00000 to 00009.
If the ending code of manufacturer code (the last one digit) ends of the numbers 0, the product code should be 5 numbers from 00000 to 00009.
If the ending code of manufacturer code (the last three digits) ends of the numbers of 300, 400, 500, 600, 700, 800, or 900, the product code should be 100 numbers from 00000 to 00099 .
If the ending code of manufacturer code (the last two digits) ends of the numbers of 10, 20, 30, 40, 50, 60, 70, 80, or 90, the product code should be 10 numbers from 00000 to 00009.
If the ending code of manufacturer code (the last two digits) ends of the numbers of 10, 20, 30, 40, 50, 60, 70, 80, or 90, the product code should be 10 numbers from 00000 to 00009.
If the ending code of manufacturer code (the last one digit) ends of the numbers 0, the product code should be 5 numbers from 00000 to 00009.
