Code 39 Extended without printed start/stop asterisks

Some label layouts and downstream systems expect the human-readable text to show only the encoded value, without Code 39's own leading/trailing "*" start/stop markers -- this generator hides those markers in the printed text by default.

Same generator, one preset applied

This experience uses the same Code 39 Extended capability as the primary generator, with the start/stop asterisks hidden from the human-readable text ("hidestars": true) instead of shown.

Example data

The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.

Workflow

Enter your data, confirm the preview, then export SVG or PNG for the label artwork.

Job-specific settings

No job-specific options beyond hiding the start/stop asterisks are applied here.

Scanning notes

Hiding the printed asterisks only changes the human-readable text -- the scanned bar pattern itself is unaffected and still requires a standard Code 39 reader.

Common mistakes

A byte outside plain ASCII (128 and above) is the most common rejection; this is unaffected by the hidestars preset itself.

Standard

Code 39 Extended (Full ASCII Code 39) is an AIM-documented extension of the base Code 39 symbology.
