Reading and generation stay in your browser. Check the result before you share, print, or open a link.
MSI Plessey stores the digits you type. This tool does not add a mod-10 check digit, so the bars match the number on the label exactly.
If your scanner requires a check digit, calculate it in your inventory system and include it in the digits before you generate.
How to use this tool
- Enter digits only.
- Generate the symbol.
- Test it on the scanner profile you actually use.
Practical guidance
If your scanner requires a check digit, calculate it in your inventory system and include it in the digits before you generate.
Checks before you use the output
Scan a sample. A reader set to require MSI mod 10 will reject a code that has no check digit.
Questions and answers
Can it encode letters?
No. Digits only.
Why is there no automatic check digit?
So the printed number is exactly the number you entered.
Where is MSI used?
Mostly older inventory and shelf labels, not retail point of sale.
