Your DOT compliance partner, nationwide.

A C/TPA — consortium/third-party administrator — is a service agent that provides or coordinates drug and alcohol testing services for employers (49 CFR §40.3). In the FMCSA Clearinghouse, it is the company an employer designates to run queries and report on its behalf: the employer names and authorizes the C/TPA in its Clearinghouse registration (§382.711(b)(3)), any employer may designate one (§382.705(c)), and an owner who drives for his or her own company must (§382.705(b)(6)). Vertical Identity is a C/TPA serving CDL drivers and motor carriers nationwide.

A C/TPA — Consortium/Third-Party Administrator — is a service agent that manages DOT drug and alcohol testing programs on behalf of employers who use commercially licensed drivers. C/TPAs handle random testing pools, result tracking, MIS reporting, and FMCSA compliance so that motor carriers don't have to manage those programs in-house.

Yes. If you hold a CDL and operate under FMCSA authority, you must be enrolled in a DOT-compliant random drug and alcohol testing program. Owner-operators cannot self-administer their own random testing, so joining a consortium managed by a C/TPA is required under 49 CFR Parts 382 and 40.

Any FMCSA-registered C/TPA can serve you regardless of your location — your physical address does not need to match the C/TPA's office because random tests are collected at drug testing collection sites in your area. Vertical Identity operates nationwide and maintains access to thousands of collection sites. You can enroll online in minutes at verticalidentity.com.

A C/TPA enrolls you in a compliant random testing pool, conducts random selections at the FMCSA-required rate (50% drug / 10% alcohol for CDL drivers), notifies you when you're selected, coordinates your collection site visit, receives results from the lab and MRO, and maintains your testing records. Vertical Identity also acts as your C/TPA in the Clearinghouse at no charge, runs the queries you order per driver, and provides a member portal where you can track your full compliance status.

A consortium pools multiple employers together so the random selections meet the statistical validity required by FMCSA — this is what makes the math work for small fleets and owner-operators with just one or two drivers. A C/TPA is the company that administers the consortium (and other testing programs). Vertical Identity is both: we run the consortium pool AND serve as the third-party administrator that handles all the compliance work.

Vertical Identity's annual membership is $85 a year for your first driver and $25 a year for each additional driver, or $295 a year for unlimited drivers — this covers the drug and alcohol testing program, random pool participation, Vertical Identity as your C/TPA in the Clearinghouse at no charge, DQF Pro driver files, and access to our member compliance portal. Tests are ordered when needed at member prices: drug tests are $69 each. Clearinghouse queries are ordered per driver at $12 (our fee; the FMCSA query credit is separate). There are no membership setup fees.

Yes. You can transfer your consortium membership at any time. Vertical Identity handles the transfer documentation and coordinates with your previous administrator to ensure there is no gap in your compliance record. Your testing history follows your DOT number.
