GS1 ISO/IEC 18004 / GS1 Spec

GS1 QR Code Barcode Generator & Specification (ISO/IEC 18004)

Generate compliant GS1 QR Code barcodes online with vector SVG and EPS output. Powered by high-speed Rust engine with strict GS1 QR Code validation.

Live Generator
22/500

Completes check digits when their position is clear. Use parenthesized AIs for GS1. Existing check digits are validated. Other formats keep their usual behavior.

Technical Specifications

Structure GS1 QR Code Data Codewords + Error Detection / Checksum + Quiet Zones
Capacity Standard GS1 QR Code data capacity and density
Character Set Compliant with GS1 QR Code specifications
Quiet Zone Requirement ≥ 10x module width (Standard quiet zone)

Common Applications

This standard is widely used in the following industries:

2D Matrix, Commercial Logistics, Identification & Tracking
Input Constraints & Parity: Engineered with Reed-Solomon Forward Error Correction (ECC) to tolerate physical damage, smudging, or partial occlusion. Configurable ECC levels ensure maximum scan reliability in high-speed sorting.
