Improve your online business with a GS1 GTIN

At Balkan eCommerce Summit 2026, Vessela Subaczewska explained how GS1 standards and GTIN identifiers play a fundamental role in modern eCommerce by improving product identification, catalog quality, marketplace efficiency, and operational scalability. The session focused on how standardized product data helps online businesses reduce errors, increase visibility, accelerate listing processes, and build trust across global commerce ecosystems.

GS1 Standards Power Global Commerce

Vessela introduced GS1 as a global, neutral, non-profit organization operating in more than 120 countries and supporting over 2 million companies worldwide. More than 1 billion products today use GS1 GTIN identifiers, making the system one of the most widely adopted global commerce standards.

She emphasized that:

GS1 is not simply a barcode organization.

Instead, its core role is:

• issuing globally unique product identifiers
• creating standardized rules
• and enabling companies across industries to “speak the same language” in commerce.

The presentation compared GS1 standards to traffic rules:
they create a unified framework that reduces confusion, improves efficiency, and enables seamless communication across supply chains, marketplaces, retailers, warehouses, and online platforms.

GTIN Enables Accurate Product Identification

A major focus of the lecture was the importance of:

accurate product identification.

Vessela explained that:
without standardized identifiers, businesses often rely on:

• internal product numbers
• custom codes
• or inconsistent descriptions,

which creates:

• duplicate listings
• incorrect categorization
• inventory confusion
• and fulfillment mistakes.

Using GTINs solves this problem by ensuring that:
every product can be uniquely identified across:

• physical retail
• online marketplaces
• logistics systems
• and digital commerce platforms.

She demonstrated how:
products that appear visually identical may still represent completely different versions, regions, or technical specifications – making standardized identification essential for accurate commerce operations.

Different Types of GTINs Serve Different Purposes

The lecture outlined the various GTIN formats used globally:

• GTIN-8 for small packaging
• GTIN-12 (UPC) primarily in the United States
• GTIN-13 as the global retail standard
• GTIN-14 for logistics and grouped packaging units.

Vessela explained that:
these identifiers create the foundation for:

• retail scanning
• product cataloging
• online listings
• supply chain automation
• and marketplace integrations.

GS1 Standards Improve Marketplace Operations

One of the strongest business cases presented was how GS1 standards improve:

marketplace efficiency and catalog quality.

According to the lecture:
using GTINs allows marketplaces to:

• merge duplicate listings
• organize products more accurately
• and group offers from multiple sellers under a single product page.

This creates:

• cleaner catalogs
• better customer experiences
• more accurate product data
• and easier product discovery.

The presentation highlighted that:
major marketplaces such as:

• Allegro
• Emag
• and other international platforms

already rely heavily on GS1 standards to manage product data consistency and operational scalability.

GTINs Increase Visibility and Conversion Rates

Another key topic was:

product discoverability.

Vessela explained that:
GTINs help products appear more accurately in:

• Google Shopping
• search engines
• and online marketplaces.

According to data referenced in the lecture:
products with GTIN identifiers receive:

• 40% more clicks
• and 20% higher conversion rates.

The reason is that:
GTINs improve:

• product legitimacy
• structured product data
• and platform confidence in listing accuracy.

Faster Product Listings and Operational Automation

The lecture also focused on:

operational efficiency.

Using GTINs allows marketplaces and sellers to:

• automatically populate product information
• match offers to existing listings
• and reduce manual input errors.

Vessela shared that:
Allegro reported:

a 36% faster listing process

when sellers use GTINs because key product attributes can be automatically generated from existing data systems.

This creates:

• faster onboarding
• fewer human mistakes
• and more scalable marketplace operations.

GS1 Supports Product Authenticity and Consumer Protection

Another important part of the lecture focused on:

trust and product authenticity.

Through systems like:

Verified by GS1,

companies and marketplaces can validate whether:

• product descriptions
• identifiers
• and company information

match official GS1 records.

This helps:

• detect counterfeit products
• identify suspicious listings
• and improve trust within marketplaces.

The presentation also explained how GTINs support:

• product recalls
• order traceability
• fulfillment accuracy
• and consumer safety processes.

When dangerous or incorrect products are identified:
GTIN-based systems allow platforms to:

• quickly locate affected inventory
• identify customers
• and remove listings efficiently.

2D Barcodes and the Future of Commerce

Vessela also discussed the future evolution of GS1 standards through:

2D barcodes.

These next-generation barcodes combine:

• physical product identification
• internet connectivity
• and access to multiple digital information sources through a single scan.

According to the presentation:
2D barcodes represent the next step in:

• omnichannel commerce
• supply chain transparency
• and connected consumer experiences.
