Creating UPC-A Barcode with Add-On Symbol in Microsoft Office Word Application

This guide provides structured instructions for generating UPC-A with supplementary add on symbols, encoding valid data characters, and managing check digits in the Microsoft Office Word Application using a professional barcode generator add in.
Create UPC-A with Two-Digit Add-On in Microsoft Office Word Application
A standard UPC-A barcode can be extended with a two digit or five digit add on symbol (supplementary barcode) for additional product information. In the Word Barcode Generator Add in, you combine main UPC-A data and add on data using a plus sign (+) as the separator.
- Example format: 12345678901+12, where 12345678901 is the main UPC-A data and 12 is the two digit add on.
- In a Word content control or linked document field (e.g., a text field linked to barcode data), enter the value 12345678901+12.
- In the Barcode Settings pane of the Microsoft Office Word Application, set the data source to reference the linked field.
- From the Barcode Type dropdown list, select UPC A +2.
- Click the Generate button to create the barcode.
The UPC-A barcode with a two digit add on is inserted into the active Word document. When the linked field value is modified, the barcode updates automatically.
Note: Using any separator other than the plus sign (+) will cause encoding failure in the Word barcode add in.
Customize UPC-A Add-On Barcode in Word
The Word Barcode Generator Add in supports full customization of UPC-A add on barcodes.
- Navigate to the 1D Barcode tab in the Word barcode settings panel.
- Locate the EAN / UPC configuration group.
- Adjust available properties to customize add on appearance and behavior.
The UPC-A add on barcode refreshes with the new settings in the Word document.
UPC-A Barcode Data Characters Encoding in Microsoft Office Word Application

UPC-A Data Character Set
UPC-A supports numeric data encoding only. Valid input characters are digits from 0 to 9.
A standard UPC-A barcode is structured into four logical parts:
- Number system digit
- Manufacturer code
- Product code
- Check digit
Note: Entering letters or symbols in the data field will generate an invalid, unscannable barcode in the Word document.
UPC-A Digit Length
Each standard UPC-A barcode consists of 12 numeric digits. The first 11 digits represent the core GS1 (Global Standard 1) business message. The 12th digit is a mandatory check digit. UPC-A may also include a supplementary add on of 2 or 5 digits.
In the Microsoft Office Word Application barcode add in, you may enter either:
- 11 main digits plus add on data, e.g., 12345678912+12 or 12345678912+12345
- 12 main digits plus add on data, e.g., 123456789128+12 or 123456789128+12345
UPC-A Check Digit in Microsoft Office Word Application
The UPC-A check digit is computed using a modulo 10 algorithm based on the weighted sum of the first 11 digits.
In the Word Barcode Generator Add in:
- You are not required to manually enter the check digit.
- The software automatically calculates the valid check digit from the first 11 digits.
- If you provide a full 12 digit string, the add in ignores the 12th digit and recalculates it.
- The generated UPC-A barcode includes the correct check digit in its symbol structure.
Note: Manually entering an incorrect check digit will not affect the final barcode, as the add in always overrides it with a valid computed value.
