EnvZone professional license directory

Your product, in the engineer’s workflow

Licensed engineers use EnvZone to verify credentials mid-project. On Spec places your product beside them at that exact moment — when the project is open and the specification list is still being written.

What’s happening right now

A consulting engineer just opened the directory

She is a project engineer at a civil and environmental consulting firm, three weeks into the design phase of a municipal wastewater treatment upgrade. Federal grant funding, state environmental permits, a local utility authority as the client. The project has been in the pipeline for two years and the design phase is finally moving.

Her list of tasks today includes verifying the license status of two sub-consultants before the team qualification submittal goes out. She opens the EnvZone directory and runs the searches. Done in a few minutes.

But the project does not close when she finishes the lookup. The specification work is ongoing. Equipment selections, product submittals, design criteria for the treatment process. That context is already open in her mind when she sees the sidebar.

Three cards. Products relevant to the work she is doing. One of them is a name she has specified before on a similar project. She clicks to learn more.

That was not a trade show encounter or a cold call from a manufacturer’s rep. It was your product, present in a professional environment where the work of specification is already underway.

That is what an On Spec placement does.

Your audience

900,000+ licensed professionals. One directory.

Every professional in the EnvZone directory holds an active or historical license issued by a state licensing board. These are the engineers, architects, and surveyors who design the projects your products go into.

PE

Professional engineers — the primary specifiers of industrial and infrastructure products

RA

Registered architects — specifiers for building systems, HVAC, lighting, and controls

PLS

Licensed surveyors — active in transportation and land development projects

Why it works

The right context changes everything.

They are already in project mode

Engineers do not use this directory casually. Every lookup is tied to an active project — a submittal, a qualification, a design review. Your product appears while that project is open, not between projects.

License-verified, discipline-specific

Every profile in this directory is sourced from official state licensing board records. The audience is not self-reported. These are credentialed professionals working in the disciplines your products serve — water, wastewater, transportation, building systems, and more.

Three spots. That is it.

Each state directory carries three On Spec sidebar placements. Not thirty. Not a rotating carousel. Three companies, visible to every professional who opens that state’s directory. When the slots are filled, they are filled.

About the directory

A credential lookup tool built for the profession

EnvZone’s license verification directory compiles public licensing records from all 50 state boards — professional engineers, registered architects, and land surveyors — into a single searchable index.

No account required. Completely free to use.

Professionals arrive here when they need fast, reliable answers about license status before project submittals, proposal preparation, and team qualification reviews. The directory is updated quarterly from official state board data.

Your On Spec placement sits in the sidebar beside every search result on the state directory pages where you choose to appear.
