Check a membership number, and find interior design professionals and studios in the IIDA network.
Verify a membership number
Check whether a membership number is genuine and current.
Every IIDA member is issued a membership number. If a designer or studio tells you they are an IIDA member, you are welcome to check it here before you engage them — tell us if the number does not check out.

A directory of the people behind the work
The full Members Directory — practice names, cities and specialisms — is available to current IIDA members. Once you are a member you can search it, list your own practice, and get in touch with designers and studios in other cities.
Listings and membership numbers are being issued as the 2027 membership year opens. If you are already a member and want your listing set up, write to us and we will do it.
Before you engage a designer
Information in the Members Directory is supplied by members themselves. Inclusion confirms membership status only. It is not a verification, endorsement, or guarantee of any member’s qualifications, competence, licensing, insurance, pricing, or the quality or outcome of their work. Please carry out your own due diligence before engaging any designer or firm — see our Disclaimer & Legal Status.
If a member has fallen short of the standards we expect, or somebody is claiming a membership they do not hold, report it to us.
