Advanced (GS1, checks, profiles, retail add-ons, supply-chain carrier)
This symbology has no tunable options — the engine picks the densest valid symbol.
Style (readable text, bar height, export size)
Bar height stretches bars vertically, which scanners ignore (only horizontal timing matters). The SVG download keeps the engine's exact geometry.

Usage
PZN labels industrial parts, documents and work orders: print it on badges, boards and bins where rugged 1D scanners operate.
- PZN on asset tags for workshop tracking
- PZN on work-order paperwork for line-side scanning
- PZN proofs exported as PNG for quick sharing
Shape
Pros
- PZN tolerates industrial printers, labels and badge stock.
- Case folding, padding and check rules are explained before encoding.
- PNG and SVG exports cover both quick sharing and print.
- The self-verify readout shows exactly what a scanner will observe.
Cons
- PZN is wider per character than 2D codes for long payloads.
- Dense narrow bars demand close, steady photography when verifying.
- Damaged or smudged labels lose characters with no error correction.
- Colored or low-contrast prints scan poorly.
Form requirements
- Enter 1234567.
- Digits only, 6–8 (check digit computed or verified).
- The symbol is decoded again locally before preview and downloads unlock.

How it works
Three steps, all on your device.
The same engine that reads barcodes writes them — every symbol is decoded again before you see it.
Type the payload
Every symbol is validated and decoded again on your device before it is shown.
Download and print
Take a resolution-independent SVG for print or a PNG for sharing. Nothing is uploaded.

What can I type for PZN?
Digits only, 6–8 (check digit computed or verified). Example: 1234567.
How does PZN handle check digits and printing?
Mod-11 style PZN check digit computed or verified. Code 39 family quiet zones apply. Export SVG for print and PNG for sharing; both render on your device.
Is my data uploaded anywhere?
No. Encoding and verification run entirely in your browser — the page makes no network requests with your data, stores nothing, and wipes the field after ten idle minutes.
