Prescribers who handle controlled substances answer to two regulators: the federal government and the state where they practice. That's why the same questions come up again and again: Is a DEA license state specific? Is a CSR the same as a DEA number? Which do I get first? This guide answers each one.
Who regulates controlled substances?
At the federal level, the Drug Enforcement Administration (DEA) enforces the Controlled Substances Act. It classifies drugs into Schedules I through V and registers every practitioner, pharmacy and facility that prescribes, dispenses or stores them.
Each state also regulates controlled substances, usually through its board of pharmacy, health department or a dedicated narcotics agency. States can be stricter than federal law, and many add their own registration, prescribing limits and prescription monitoring requirements.
What is a DEA registration?
A DEA registration (often called a "DEA license" or "DEA number") is the federal authorization to prescribe, administer or dispense controlled substances. Practitioners renew it every three years. Under DEA's most recent fee rule, the practitioner fee is $888 for the three-year period; confirm the current amount on DEA's Diversion Control website before you apply.
Is a DEA license state specific?
Yes. Although DEA is a federal agency, each registration is tied to a specific state and practice address. A practitioner who prescribes controlled substances in more than one state generally needs a separate DEA registration in each state. Moving to a new state also means updating or obtaining a new registration, not simply carrying the old one over.
So the accurate answer to "is a DEA license federal or state?" is: it's a federal registration, issued state by state.
What is a CSR license?
A CSR is a state controlled substance registration. Depending on the state, it may be called a CSR, a CDS (controlled dangerous substance) registration, or a state controlled substance license. It authorizes you to handle controlled substances under that state's law.
Not every state issues one. Where a state does, the CSR is usually required before DEA will issue a registration for that state, because DEA confirms you are authorized under state law first. Examples of states with their own registration include New Jersey (a CDS registration), Oklahoma (registration with the Oklahoma Bureau of Narcotics), Wyoming, Illinois, Louisiana and New Mexico. Requirements change, so always check the current rules with the state board or agency.
Pharmacies, clinics and other facilities that store or dispense controlled substances may need their own state registration as well, separate from the individual prescriber's.
Is a controlled substance license the same as DEA?
No. They are two different credentials from two different authorities:
| DEA registration | State CSR / CDS | |
|---|---|---|
| Issued by | Drug Enforcement Administration (federal) | State board or agency |
| Required in | Every state where you prescribe controlled substances | Only states that have their own registration |
| Order | Usually second, after state authority is in place | Usually first, where required |
| Renewal | Every 3 years | Set by each state (often 1–3 years) |
| Scope | Federal authority, tied to one state and address | That state only |
In a state that requires both, prescribing with only one of them is not compliant.
Which do I get first?
- Your professional license in the state (MD, DO, NP, PA or other prescriber).
- Prescriptive authority, if your state requires a separate step for your license type, such as a collaborative agreement or furnishing number for some NPs and PAs.
- The state CSR, in states that issue one.
- The DEA registration for that state.
- Prescription monitoring program (PDMP) registration, required for prescribers in many states.
Then update your CAQH profile and payer files with your new DEA certificate, because payers check it during credentialing.
Do controlled substance rules vary by state?
Yes, a great deal. States differ on whether a CSR exists, how often it renews, prescribing limits for opioids and stimulants, PDMP check requirements, and which schedules nurse practitioners and physician assistants may prescribe. Federal law sets the floor; each state can add to it.
Nurse practitioners and physician assistants
NPs and PAs can hold DEA registrations, but only for the schedules their state allows. Some states restrict Schedule II prescribing or require a collaborative agreement first. Your DEA registration will reflect the schedules your state authority permits.
Telehealth prescribing of controlled substances
Federal rules on prescribing controlled substances by telemedicine without an in-person visit have run on temporary extensions since the pandemic. The current extension runs through December 31, 2026, and DEA has a permanent special-registration rule under review. Separately, a permanent rule allows buprenorphine for opioid use disorder to be prescribed by telemedicine under specific conditions.
Two points hold regardless: you need a DEA registration in the state where the patient is located, and state telehealth rules still apply. Because these rules are changing, check DEA's guidance before building a practice around them.
Common mistakes we see
- Opening in a second state with only the first state's DEA registration.
- Applying to DEA before the state CSR is issued, which delays the application.
- Letting a CSR lapse because it renews on a different cycle than DEA.
- Forgetting to update the DEA address after moving practice locations.
- Not uploading the new DEA certificate to CAQH, which stalls payer credentialing.
Juggling these registrations across states is exactly the kind of work our DEA registration and licensing team handles for prescribers of every specialty.
Frequently asked questions
Is a DEA license state specific?
+
Yes. A DEA registration is federal but is issued for a specific state and address. You generally need a separate registration for each state where you prescribe controlled substances.
Is a DEA license federal or state?
+
Federal. DEA is a federal agency, but each registration is tied to one state, and many states also require their own controlled substance registration.
What is a CSR license?
+
A CSR is a state controlled substance registration that authorizes you to handle controlled substances under that state's law. Not every state issues one.
Is a controlled substance license the same as a DEA registration?
+
No. A CSR is issued by a state and a DEA registration by the federal government. In states that require both, you need both.
Which comes first, the CSR or the DEA registration?
+
In states that issue a CSR, you usually need the CSR first, because DEA checks that you are authorized under state law.
How often does a DEA registration renew?
+
Every three years for practitioners. State registrations renew on their own schedules.
