2D Barcode Generation¶
Generate GS1-compliant QR codes and DataMatrix barcodes instantly. Every code is a valid GS1 Digital Link URI, ready for the Sunrise 2027 transition from linear barcodes to 2D data carriers.
GS1-Compliant Barcode Types¶
GTIN1 generates every symbology you need for retail, logistics, and supply chain operations. Each barcode encodes standards-compliant data that scanners worldwide can interpret.
| Symbology | Description | Example |
|---|---|---|
| QR Code with GS1 Digital Link | Consumer-optimized 2D barcodes encoding a full GS1 Digital Link URI. Scannable by any smartphone. | https://gtin1.com/01/00614524740689 |
| GS1 DataMatrix | Compact 2D matrix symbology for industrial marking and small packaging. | (01)00614524740689(10)LOT2024A |
| EAN-13 / UPC-A | Legacy linear barcodes for backward compatibility with existing POS systems. | 0 614524 740689 |
| ITF-14 | Interleaved 2-of-5 symbology for shipping cartons. | 1 0614524 740689 3 |
| Code 128 / GS1-128 | High-density linear barcodes for supply chain and shipping with AI encoding. | (01)00614524740689(17)261231 |
Granularity Levels¶
Barcodes can encode product information at different levels of specificity. GTIN1 supports all three GS1 granularity levels.
Level 1: Trade Item (GTIN)¶
The foundational level. A GTIN identifies a product at the SKU level using Application Identifier 01.
Enables: product pages, Digital Product Passport, basic traceability.
Level 2: Lot / Batch (AI 10)¶
Adds a lot or batch number via Application Identifier 10. Connects a barcode to a specific production run.
Enables: recall targeting, lot-level traceability, FSMA 204 compliance.
Level 3: Serial Number (AI 21)¶
The most granular level, assigning a unique serial number to each unit.
Enables: unit authentication, anti-counterfeiting, warranty tracking.
Export Formats¶
Download barcodes in the format that fits your workflow.
- SVG (Vector) -- Scalable vector graphics that render crisply at any size. Recommended for print production and packaging design.
- PNG (Raster) -- High-resolution raster images for digital displays, e-commerce, and web applications. Configurable DPI.
- PDF (Print-Ready) -- Print-ready PDF files with embedded vector barcode graphics, proper margins, and quiet zones.
All barcodes include required GS1 quiet zones for reliable scanning. QR codes support four error correction levels: L (7%), M (15%), Q (25%), and H (30%).
Batch Generation¶
Generate thousands of barcodes in a single operation. GTIN1 processes batch jobs asynchronously.
- High-Volume Production Runs -- Upload a CSV or select items from your product registry
- Async Job Processing -- Large batch jobs run in the background with real-time progress tracking
- Downloadable Archives -- Completed batches are packaged into a ZIP archive organized by product or lot

Sunrise 2027 Readiness¶
The retail industry is transitioning from 1D linear barcodes to 2D data carriers by the end of 2027.
During the transition, products carry both a traditional linear barcode and a QR code with GS1 Digital Link. GTIN1 generates both symbologies from the same product record, ensuring consistency across legacy and modern scanning environments.
| Year | Milestone |
|---|---|
| 2025 | Early adopter retailers begin accepting 2D barcodes at POS |
| 2026 | Broader retailer rollout of 2D-capable scanners |
| 2027 | All POS systems must read 2D barcodes |
| 2028+ | Phased retirement of standalone linear barcodes |
What barcode formats does GTIN1 support?
GTIN1 supports QR Code with GS1 Digital Link, GS1 DataMatrix, EAN-13, UPC-A, ITF-14, Code 128, and GS1-128.
Can I generate barcodes in bulk?
Yes. Upload a CSV or select items from your product registry. Batch jobs run asynchronously and are delivered as downloadable ZIP archives.
What export formats are available?
SVG for print production, PNG for digital use, or PDF for print-ready documents. All formats include proper quiet zones and GS1-compliant sizing.
How do I prepare for Sunrise 2027?
Register your products in GTIN1 and generate QR codes with GS1 Digital Links. Use dual symbology during the transition: keep the existing linear barcode and add a QR code.
