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.

DIA does not supply any contact information to vendors that are not included in the Authorized Vendor List below.

DIA cannot assist with any issues that may arise from using an unauthorized vendor.
