What is the GS1 Digital Link Simulator?

The GS1 Digital Link Simulator is a free interactive tool that lets you experiment with GS1 Digital Link URI construction. Enter any GTIN (8, 12, 13, or 14 digits), add Application Identifiers like batch numbers, serial numbers, and expiration dates, and watch a standards-compliant URI build in real time. The built-in compliance checker validates your configuration against 12 GS1 rules across five categories, so you can catch issues before creating production QR codes.

Simulator Features

GTIN Validation

Validates any GTIN format (8, 12, 13, or 14 digits) with real-time check digit verification using the GS1 modulo-10 algorithm.

Application Identifier Browser

Browse and search over 25 Application Identifiers across five categories. Add batch numbers, serial numbers, dates, weights, and country codes.

Live URI Builder

Watch a color-coded GS1 Digital Link URI build in real time as you add identifiers. Copy the result with one click.

Compliance Checker

Run a 12-point compliance audit covering GTIN validity, URI structure, qualifier ordering, data formats, and more.

Frequently Asked Questions

Is this tool free?

Yes, the GS1 Digital Link Simulator is completely free with no account required. Use it to learn, experiment, and validate your GS1 data before creating production QR codes.

What is a GS1 Digital Link?

A GS1 Digital Link is a web URI that encodes product identification data (like a GTIN and batch number) in a structured, standards-compliant format. It replaces traditional barcodes with scannable QR codes that link to dynamic web content.

What GTINs can I use?

The simulator supports GTIN-8, GTIN-12 (UPC-A), GTIN-13 (EAN-13), and GTIN-14 formats. You can use any valid GTIN, or try one of the example products to get started quickly.

How do I create a real GS1 QR code?

Once you've validated your GS1 Digital Link configuration in the simulator, sign up for a QRWolf account to create scannable QR codes with tracking, bulk serial generation, and hosted product pages.
