Similar companies you should also watch out for:

  • Fair Guide: This letter comes from the Austrian or Slovak company Construct Data Publishers, suggesting it is intended to pass on corrections to the listing in FAIR Guide and a registration at to keep your company information up-to-date. After signing the letter, these companies are tied to an annual payment of a substantial amount for a period of time, for a consideration that is not really made clear.
  • Expo Guide: Expo Guide sends companies a letter with a form to correct data for a listing in Expo Guide. Again, after signing the letter, one is bound to pay an annual fee of a substantial amount for a specified period of time.
  • International Fairs Directory: International Fairs Directory operates out of Costa Rica. This company states at the bottom of the letter that there is no business relationship with the fair organizer. Nevertheless, they do ask to check your business information online and add to it if necessary. This seems risky and we do not recommend responding to this.
