Scam Warning

Directory Guides (Domestic and International) & Unauthorized Partners of Informa Exhibitions, U.S. For several years, different companies selling listings in their “Exhibitors Directory” or “Fair Guides” have been actively soliciting exhibitors who participate at numerous trade shows throughout the country, including World of Concrete. The companies typically make it appear they have received your information from the World of Concrete and that there is a connection between their “guide” and the World of Concrete. In their information, they may imply that your company has engaged with their “guide” before saying “update your pre‐registered listing in our exhibitors’ directory...” or “updating is free of charge.” However, in the agreement in very small type is a binding agreement that automatically renews every year (some up to three-year commitments charging $1,500–$5,000 each year). Similar attempts have been made for housing, list rental programs, and partners of the show selling sponsorships packages. The list of official vendors that we work with are listed on this page or in your exhibitor service manual.

We are aware of several companies that are attempting to sell exhibitors the WOC 2026/27 attendee list. This is a scam. These companies are not affiliated with WOC and the data they are attempting to sell you is not legitimate. If you receive any calls or emails of this nature, please contact your WOC sales representative email or exhibit@worldofconcrete.com.
