I downloaded a free version of Code 3 of 9 and the scanner won't read it

Issue

Free barcode fonts often lack the proper symbology encoding required for scanners to read them correctly. While they may appear visually similar to valid barcodes, they don't encode the data in the format scanners expect.

Solution

Use a commercial-grade barcode font or barcode generation software that properly implements the Code 3 of 9 (Code 39) symbology standard. These tools ensure:

  • Correct start and stop characters
  • Proper encoding of data
  • Appropriate spacing and formatting
  • Checksum digits when required

Recommended Approach

For reliable barcode scanning:

  1. Purchase a commercial barcode font designed for Code 3 of 9 from a reputable vendor.
  2. Use barcode generation software that creates properly formatted Code 39 barcodes.
  3. Test all barcodes with your scanner before printing in production.
