Authorized Vendors
As of December 29, 2025
With any event, there are multiple companies involved, and it can be difficult to remember who to contact for specific services. You may also be contacted directly by vendors and wish to confirm whether they are officially partnered with DIA.
To help you navigate this, DIA has established an Authorized Vendor Program. Authorized vendors for the DIA 2026 Global Annual Meeting will display an official DIA Authorized Vendor logo as confirmation of approval.
Authorized Vendor Logo
Vendors displaying the official DIA 2026 Authorized Vendor logo have been reviewed and approved to provide services for the DIA 2026 Global Annual Meeting. If a company does not display this logo, it is not an authorized DIA vendor.
DIA 2026 Unauthorized Vendors
DIA does not supply any contact information to vendors that are not included in the Authorized Vendor List below.
If you have doubts about whether a company has been approved to work for the DIA 2026 Global Annual Meeting, please contact:
Americas.Exhibits@DIAglobal.org
DIA cannot assist with any issues that may arise from using an unauthorized vendor.
