Where FDA-registered 503B outsourcing facilities are, by jurisdiction
As of 2026-08-28, FDA's published list carried 97 registered outsourcing facilities, spread across the jurisdictions in the table below and concentrated heavily in a handful of them. The count is worth far less than it looks: registration is federal and location-independent, so the number that decides whether a facility may ship office stock to your practice is not how many sit in your state but whether the facility holds your state's licence to ship into it.
A 503B outsourcing facility is the route through which a clinic can lawfully hold most compounded stock without a patient-specific prescription, so the first question an operator asks is usually where these facilities are. The distribution is the answer, and it is more lopsided than most people expect: a small number of jurisdictions hold most of the registered facilities, and a majority of U.S. jurisdictions hold none at all.
The second question is the one that actually decides anything, and the count above does not answer it. Registration under section 503B is federal, and a registered facility is not confined to its own state. What governs whether it may ship into yours is your state’s law on receiving — usually a nonresident or out-of-state licence, and in several states a wholesale distributor licence on top of it.
