How Many 503B Pharmacies Are There?

As of early 2026, there are 93 FDA-registered 503B outsourcing facilities spread across 27 U.S. states. This number fluctuates as new facilities register and others withdraw their registration.

The majority of facilities are concentrated in a handful of states. Florida and Texas each have 15 registered facilities, together accounting for nearly a third of all 503B pharmacies in the country. New Jersey follows with 9 facilities, reflecting its role as a pharmaceutical industry hub.

Many states have no registered 503B outsourcing facilities at all. However, because 503B facilities can distribute medications interstate, healthcare providers in any state can work with facilities located elsewhere.

How to Choose a 503B Pharmacy in Your State

While proximity to a 503B facility can offer logistical advantages, it should not be the only factor in your decision. Here are key considerations:

FDA registration status: Confirm the facility appears on the FDA's registered outsourcing facilities list
Inspection history: Review the facility's FDA inspection results, Form 483 observations, and any warning letters
Product capabilities: Ensure the facility compounds the specific preparations you need (sterile injectables, non-sterile, hazardous drugs, etc.)
Shipping and logistics: Evaluate cold chain capabilities if needed, delivery timelines, and minimum order requirements
Quality documentation: Request certificates of analysis, stability data, and evidence of cGMP compliance

Understanding 503B vs. 503A by State

It is important to note that this directory covers only 503B outsourcing facilities — those registered with the FDA under Section 503B of the FD&C Act. Each state also has its own traditional 503A compounding pharmacies that are regulated at the state level, not by the FDA.

The key differences: 503B facilities operate under cGMP (the same manufacturing standards as conventional drug companies), can compound without patient-specific prescriptions, and can ship interstate. 503A pharmacies compound individual prescriptions under state pharmacy board oversight.
