What Is GIATA MultiCodes?

Unified Hotel Identification for Cleaner Data

GIATA MultiCodes is our commercial hotel mapping solution that assigns a unique GIATA-ID to each property. It consolidates numerous supplier codes into a single, accurate identifier, crucial for travel platforms, OTAs, and tour operators.

GIATA MultiCodes is the foundation for deduplication across the travel industry. By linking duplicate property records from thousands of sources into one unique GIATA ID, MultiCodes ensures that OTAs, bedbanks, tour operators and other distributors can merge inventory cleanly and reliably. This allows them to:

  • Offer the most competitive rates to travelers by displaying all available offers for the same hotel under a single listing.

  • Reduce booking errors caused by mismatches or duplicate property data.

  • Increase conversion by presenting a seamless, clear comparison of offers to end users.

Key Highlights

  • Covers over 1.39 million accommodations from 453 suppliers, processing 189 million supplier codes

  • Mapping accuracy of 99.99962%, achieved through a combination of automated mappings and manual validation

  • Trusted industry-wide, with major clients like OTAs, GDSs, and wholesalers leveraging its reliability

How MultiCodes Works

  1. Automated Mapping
    Incoming supplier codes are analyzed and matched to existing GIATA-IDs using advanced algorithms.

  2. Manual Review
    A dedicated team reviews ambiguous or low-confidence matches, ensuring precision.

  3. Digital Fingerprint
    Each property is represented by a unique data profile, including geolocation, images, and features, so it's swiftly and correctly identified in future mappings.

  4. Daily Updates
    New and updated information continuously refines the mapping database.
