Royal Mail (RM4SCC) specification

RM4SCC (Royal Mail 4-State Customer Code) is used by the British postal service for automatic sorting. Each bar can have 4 states: full, ascender, descender or tracker.

  • Characters: uppercase letters A–Z and digits 0–9.
  • Typical content: British postcode + delivery point suffix, without spaces, e.g. LE28HS9Z.
  • The check character is calculated and added automatically. Bar height is fixed by the standard.

How to use

  1. Type the content. To create several barcodes, put one per line.
  2. Adjust size, height, margin and colors. The preview follows every change.
  3. Download each barcode in the format you need, or all of them as a ZIP.

This symbology has dimensions fixed by its standard: PDF, SVG and AI are produced at real size. PNG and JPG use the chosen pixel resolution. If your printer warns about ink spread, increase the bar width reduction.
