Functions and features

The GIATA ID is the basis for MultiCodes. The following can be booked individually:

  1. Supplier and Tour Operator Codes
  2. GeoCodes
  3. Property addresses
  4. Chain affiliations

Our hotel database contains over 1,081,000 unique hotels or hotel complexes (10,195 parent IDs), each of which has a unique GIATA Hotel ID. The master data for our matching process is consistently delivered by more than 550 content providers (suppliers), including almost all established tour operators, as well as international OTAs, bedbanks, DMCs, hotel wholesalers and review portals. MultiCodes licensees may request the inclusion of additional suppliers at any time for no extra cost. First, their data is matched by a software, which is followed by a manual matching process. After each matching phase, all assignable hotel data will be uploaded onto our database, and previously missing properties will be newly created. All data can be accessed through an XML API and will be continuously updated and augmented.
