Short answer
Short answer: pharmacy suppliers are the businesses a pharmacy, clinic or laboratory buys prescription drugs and related stock from, and for prescription drugs in the U.S. the first test is licensure. FDA states that “Prescription drugs should only be purchased from wholesale drug distributors with a valid license in the U.S.” Verify the license with the state, check FDA’s annual reporting database, then compare contract terms.
This page is general procurement information, not legal, regulatory or medical advice. Confirm requirements for your own state and facility with your board of pharmacy or compliance office.
What pharmacy suppliers and pharmacy wholesale mean
“Pharmacy suppliers” is a buyer-side phrase. It covers the wholesale drug distributors and third-party logistics providers (3PLs) that sit between manufacturers and the pharmacy shelf, which many buyers also call “pharmacy wholesale.” Under the Drug Supply Chain Security Act (DSCSA), FDA says wholesale drug distributors and 3PLs must be appropriately licensed and must report licensure and other information to FDA annually. This page is the buyer’s workflow. For the licensing side of the business, see pharmaceutical wholesaler licensing; for the law itself, see the Drug Supply Chain Security Act; for the industry accreditation, see VAWD accreditation. For non-drug stock, how to find wholesale suppliers covers sourcing in general.
How to verify license and FDA reporting
FDA’s licensure-check page gives two checks, and they answer different questions.
- State license. Check the licensure website of the state agency responsible for licensing wholesale distributors, in the state where the distributor is conducting business. FDA’s page lists the responsible agency for each state, such as a board of pharmacy or a state department of commerce.
- FDA annual report. Search FDA’s annual reporting database to see whether the distributor or 3PL submitted an annual report to FDA. The database is searchable online, can be downloaded, and is updated every business day. Each line represents a license for a particular facility, and one facility can have several lines.
A database entry is not an approval. FDA states that reporting by a wholesale drug distributor or 3PL does not mean the facility is licensed or approved by FDA, or that it complies with applicable state and federal regulations. Treat the database as one evidence point next to the state license, not as a substitute for it.
Supplier types and what each check covers
| Supplier type | What FDA’s pages say | Where to check |
|---|---|---|
| Wholesale drug distributor | Must be appropriately licensed and report licensure information to FDA annually | State licensing agency, then FDA annual reporting database |
| Third-party logistics provider (3PL) | Must also be authorized when a manufacturer, wholesale distributor or dispenser uses it to coordinate warehousing or other logistics services | State licensing agency, then FDA annual reporting database |
| Drug manufacturer (registered establishment) | Not in the annual reporting database; registrants under section 510 of the Federal Food, Drug, and Cosmetic Act are in FDA’s drug establishments current registration site (DECRS) | DECRS |
| Outsourcing facility (section 503B) | Not in the annual reporting database | FDA’s outsourcing facility registration, not the wholesaler database |
Checklist of documents
FDA lists what wholesale distributors and 3PLs must report each year, which gives a buyer a concrete set of requests. Ask the supplier for:
- the state license number and issuing state agency for each facility that will ship to you, then confirm it on the state website rather than relying on a copy;
- its contact information for those facilities, which FDA says is part of the annual report;
- a statement of any significant state or federal disciplinary actions, which FDA says must also be reported;
- how it handles a product it determines to be illegitimate. FDA’s DSCSA page says to notify FDA within 24 hours after determining a product is illegitimate, so ask who at the supplier does this and how you will be told.
For a wider vendor review, supplier audits and supplier risk assessment cover how to document what you find.
Where it matters for labs and clinics
FDA’s licensure page frames the risk plainly: dealing with unlicensed or unauthorized trading partners exposes patients to medicines that could be counterfeit, stolen or diverted. Buyers such as clinic pharmacies and laboratories can apply the same first check: confirm the license in the state where the distributor is conducting business with you.
Common misunderstandings
“The supplier appears in FDA’s database, so FDA approved it.”
No. FDA says reporting does not mean the facility is licensed or approved by FDA.
“Any registered drug company can be checked in the same place.”
No. Manufacturers registered under section 510 and outsourcing facilities registered under section 503B are not in the reporting database.
“A 3PL is just a warehouse, so it needs no check.”
FDA says 3PLs must also be authorized when a manufacturer, wholesale distributor or dispenser uses one to coordinate warehousing or other logistics services.
FAQ
What is a pharmacy supplier?
A pharmacy supplier is a business that sells or distributes drugs and related stock to pharmacies. For prescription drugs in the U.S. this usually means a licensed wholesale drug distributor, sometimes with a 3PL handling warehousing.
What does pharmacy wholesale mean?
It means buying prescription drugs from a wholesale drug distributor instead of directly from each manufacturer. FDA says prescription drugs should only be purchased from wholesale drug distributors with a valid license in the U.S., and distributors must report licensure information to FDA annually.
How do I check that a wholesaler is licensed?
Look up the state license on the responsible state agency’s website, then search FDA’s annual reporting database. FDA’s licensure-check page links the agency for each state.
