Why won't my barcode scanner read a VIN barcode with spaces or lowercase letters?

Automotive VIN standards (ISO 3779 and AIAG B-4) strictly require 17 uppercase alphanumeric characters and forbid the letters I, O, and Q. ZPL Bench automatically validates all 17 positions and verifies the 9th-position Modulo 11 check digit before encoding.

Are the numbers from the Random VIN Generator real registered vehicles?

No. Random test VINs combine authentic automaker WMI prefixes (such as 1FT for Ford or 1HG for Honda) with randomized serials and a mathematically valid 9th-position Mod-11 check digit. They are designed strictly for DMS software testing, scanner QA, and dealership workflow demos.

VIN Standard

ISO 3779 / 49 CFR Part 565 (17 characters; excludes I, O, and Q)

Check Digit Math

Position 9 weighted Modulo 11 checksum (weights 8..2, 10, 0, 9..2; remainder 10 = X)

Supported Symbologies

Code 39 (AIAG B-4 style without start/stop display) & 2D Data Matrix ECC 200

Vehicle Spec Lookup

Explicit on-demand NHTSA vPIC API decode (Year, Make, Model, Trim, Body Class)

Printer settings use 8 / 12 / 24 dots per millimeter. Nominal 203 / 300 / 600 DPI names correspond to effective 203.2 / 304.8 / 609.6 DPI device grids. Screen dimensions use the CSS reference of 96 px/in.

Operating procedure

Enter a real 17-character VIN or choose the Random VIN test-data workflow.

Select Code 39 or Data Matrix, set the physical stock and whole-dot module width.

Review the local Mod-11 result, optionally request NHTSA decoding, and export the scan-ready label files.

Preflight validates supported identifiers and geometry; it does not certify scanner grades. Fix every red error before exporting.
