Human-Readable Interpretation (HRI)
The human-readable interpretation is the plain-text version of a barcode's data printed alongside the symbol, so people can read and key in the value when scanning is impossible.
What You Need to Know
GS1 rules specify exactly where HRI appears for each retail symbology — below the bars, in a sanctioned font size, with the leading digit of an EAN-13 conventionally printed in the left margin. HRI is not decoration: cashiers key it when a symbol is damaged, and receiving clerks reconcile it against packing lists. GS1 also mandates interpretive text placement for GS1-128 Application Identifier strings, formatting AI parentheses like (01) and (10) in the printed line.
Two rules keep HRI safe. First, never let it intrude into the quiet zone — it belongs below the symbol, in dedicated space. Second, the HRI is a fallback, not a validation: it must be generated from the same data as the bars, never typed independently, or the label will faithfully print a mismatch between what humans and scanners read.
