How GDSN Validation Works

01

Enter Product Data

Input your GTIN barcode, product name, brand, GPC category, and net content. For food products, add allergens and nutritional values per EU LMIV.

02

Multi-Market Check

We validate against France (PARANGON), Germany (1WorldSync), and Spain (AECOC) — checking GTIN checksums, required fields, and data format rules per country.

03

Fix & Sync

See exactly what needs fixing for each market. Then create a free Syncra account to resolve issues and sync directly to European data pools.

What We Validate

Our validator checks your product data against GS1 global standards and country-specific GDSN requirements for European markets.

GTIN Checksum Verification

Validates GTIN-8, GTIN-12, GTIN-13, and GTIN-14 barcodes using the GS1 standard check digit algorithm.

GPC Classification

Checks that your GPC (Global Product Classification) category code is valid and recognized by European data pools.

EU LMIV Compliance

For food products, validates allergen declarations, ingredient lists, and nutritional information per EU Regulation 1169/2011.

Country-Specific Rules

Each European market has different mandatory fields. We check requirements for France (PARANGON), Germany (1WorldSync), and Spain (AECOC).

Nutritional Data Format

Validates that energy values include both kJ and kcal, and cross-checks logical consistency (e.g., saturated fat ≤ total fat).

Data Pool Compatibility

Ensures your product data structure matches the format expected by each country's GDSN data pool operator.

Frequently Asked Questions

What is GDSN and why does it matter for European markets?

GDSN (Global Data Synchronisation Network) is the GS1-managed network that enables product data to flow between manufacturers and retailers. European retailers like Carrefour (France), EDEKA (Germany), and Mercadona (Spain) require GDSN-compliant product data for listing products. Without proper GDSN compliance, your products cannot appear on their shelves.

What is a GTIN and how is the check digit calculated?

A GTIN (Global Trade Item Number) is a unique product identifier — commonly known as a barcode number. GTINs come in 8, 12, 13, or 14-digit formats. The last digit is a check digit calculated using the GS1 standard algorithm: alternating multiply-by-1 and multiply-by-3 from right to left, then subtracting from the nearest multiple of 10. Our validator checks this automatically.

What is GPC classification?

GPC (Global Product Classification) is a GS1 standard for categorizing products. Each product must have a valid GPC category code for GDSN publication. This ensures products are correctly classified across all markets — for example, '10000672' for Sauces/Spreads/Dips or '10000576' for Beverages.

What is EU Regulation 1169/2011 (LMIV)?

EU Regulation 1169/2011, known as LMIV (Lebensmittelinformationsverordnung), sets mandatory food labeling requirements across the EU. It requires allergen declarations, ingredient lists, and nutritional information (energy in both kJ and kcal, fat, saturated fat, carbohydrates, sugars, protein, and salt per 100g/100ml) for all pre-packaged food products.

What are the differences between French, German, and Spanish market requirements?

Each market has specific requirements beyond the EU baseline. France (via PARANGON/Agena3000) uses the AS2 protocol and requires descriptions in French. Germany (via 1WorldSync/atrify) requires a GLN, product dimensions, gross weight, and descriptions in German. Spain (via AECOC/GS1 Spain) requires country of origin and Spanish-language descriptions. All three require full EU LMIV compliance for food products.

Is this validator free to use?

Yes, the GDSN validator is completely free with no login required. You can validate as many products as you want. If you need to fix issues and sync your product data to European data pools, you can create a free Syncra account (up to 5 products) or upgrade for full marketplace integration.
