Application Examples of Compliant Apparel GTIN + GS1 Digital Link (Jianhe Clothing · Pure Cotton Basic Long-Sleeve T-Shirt)

I. Generation of Compliant Apparel GTIN (China 693 Manufacturer Prefix, Apparel)

1. GTIN-13 Basic Encoding (Retail Checkout Standard for Apparel)

Apparel Industry Coding Rule: Different sizes and colors of the same style must be assigned independent GTINs. Example Item: Jianhe Clothing Pure Cotton Basic Long-Sleeve T-Shirt (White, Size L)

Country Prefix: 693 (Common manufacturer prefix segment for Chinese mainland apparel)
Manufacturer Code: 51892 (Simulated GS1-registered manufacturer identification code for Jianhe Clothing)
Product Code: 0047 (Item code for the white, size L pure cotton long-sleeve T-shirt)
Original 12 Digits: 693518920047
Check Digit (Modulo 10 Algorithm): 4
Complete GTIN-13: 6935189200474

2. Standardized 14-Digit GTIN (14-Digit Format Mandatory for Digital Link, Add Leading Zero for Retail Single Item)

For a single retail item without case-level identification, the indicator digit is fixed as ‘0’. This generates a compliant 14-digit code compatible with the GS1 Digital Link standard:
Complete GTIN-14: 06935189200474

Structural Breakdown

Indicator Digit	Manufacturer Prefix	Product Code	Check Digit
0	69351892	0047	4

Adding a leading zero unifies the code to 14 digits, meeting the GS1 Digital Link global URI resolution specification. It is universally applicable for scanning in both online e-commerce and physical retail.

III. Deployment on Hang Tags/Wash Care Labels and QR Code Generation Specifications

Parsing Logic

Print the complete Digital Link long-format QR code on hang tags and wash care labels; consumers can scan directly with their phone’s native camera.
The backend system intercepts and automatically parses URL parameters: the 14-digit GTIN matches against the style database, ’10’ batch enables supply chain traceability, ’22’ variant displays the corresponding size/color details, and the ’21’ serial number enables unique item anti-diversion tracking.
Supports multi-device adaptability: data can be retrieved on mini-programs, H5 Digital Product Passports, and in-store sales terminals.

Apparel Printing Specifications (Standard QR Code for Hang Tags/Wash Care Labels)

Minimum Code Size: 14mm x 14mm for hang tags; minimum 10mm x 10mm for garment wash care labels (including a 2mm safety margin to prevent interference from fabric wrinkles or washed-out colors).
Accompanying Human-Readable Text: Print the complete GTIN-13 (6935189200474) below the QR code to facilitate manual entry and backend verification in retail systems.
Visual and Material Adaptation:
- Paper Hang Tags: Use high-contrast black code on a white background.
- Woven Wash Care Labels: Use wash-resistant ink; for dark fabrics, use light grey QR codes to avoid blurring from high-temperature washing.
Placement: Center the code on hang tags; on wash care labels, place it on a flat interior area, avoiding seams and printed color blocks.

Extended Upgrades for the Apparel Industry

Add AI 21 Serial Number: Enables unique item identification for anti-diversion, counterfeit traceability, and returns/exchanges verification.
Integrate Digital Link Landing Page Content: Fabric composition, washing standards, size charts, outfit suggestions, membership points, and direct online store access.
Adapt to EU Digital Product Passport (DPP): Add sustainability traceability, recycling guides, and carbon footprint data to meet export compliance requirements.
Connect to Retailer ERPs and E-commerce Platforms: Scans automatically update inventory, pricing, and return policies, integrating online and offline supply chains.
Enhance Marketing: Scanning can lead to coupons, new product subscriptions, tutorial videos, and membership points.

Supplementary Notes

This case strictly follows the GS1 AI 01 global trade item identification standard. The GTIN-14 code 06935189200474 is for demonstration purposes only.
Core Apparel Industry Rule: Any change in style, color, or size requires the assignment of a new, unique GTIN. The same code cannot be reused.
For actual commercial deployment, you must register with the Chinese National Coding Center to obtain a legal manufacturer identification code. It is prohibited to fabricate manufacturer prefixes.
QR codes on wash care labels must use specialized wash-resistant and abrasion-resistant printing processes. For long-term circulation, consider using Data Matrix codes for higher error correction rates.
