RM4SCC for mail-sort label stock
Mail-merge and franking systems printing onto standard mail-sort label stock use this generator with a fixed, more visible bar height applied.
Same generator, one preset applied
This experience uses the same RM4SCC capability as the primary generator, with a fixed 20mm bar height ("height": 20) preset instead of bwip-js's own notably shorter ~4.4mm default.
Example data
The generator is seeded with a bwip-js-verified valid value, distinct from the primary's example.
Workflow
Enter your RM4SCC data, confirm the preview, then export SVG for the mail-piece artwork.
Job-specific settings
No job-specific options beyond the fixed bar height are applied here.
Scanning notes
RM4SCC requires a 4-state postal barcode reader, not a standard 1D linear scanner.
Common mistakes
Using a character outside RM4SCC's own 36-symbol alphabet is the most common rejection.
Standard
RM4SCC is Royal Mail's own UK mail-sortation barcode standard.
