If you are an Advanced Practice Registered Nurse (NP, CRNA, CNS, or CNM) who plans to prescribe controlled substances, your federal DEA registration is necessary, but in about half the country it is not sufficient. Many states layer a second credential on top, usually called a Controlled Substance Registration (CSR) or Controlled Dangerous Substances (CDS) registration. In Missouri it is called a BNDD (Bureau of Narcotics and Dangerous Drugs) registration. Names differ; the practical effect is the same: no state CSR means no legal prescribing of scheduled medications in that state, even if your DEA number is active.
This guide explains how the state CSR layer works, which states currently require it in 2026, and how APRNs typically sequence the paperwork when moving across state lines.
Federal DEA Is Required Everywhere. State CSR Is the Add-On.
A federal DEA registration is required in every U.S. state and territory for any APRN who prescribes, administers, or dispenses controlled substances in Schedules II through V. That part is universal.
The state CSR (or CDS, or BNDD) is an additional, state-issued credential. It is usually administered by the state board of pharmacy, the state department of health, or a dedicated state narcotics bureau. Some states limit it to certain schedules, some require it for all schedules, and some restrict APRN prescribing of Schedule II separately from the CSR itself.
States That Require a State-Level CSR or CDS in 2026
Based on currently published state board guidance, the following states require APRNs to hold a state controlled substance credential in addition to federal DEA. Always verify with the issuing agency before filing — these rules change, and a handful of states have moved registrations between agencies in the last two years.
- Alabama — Alabama CSC (Controlled Substances Certificate), issued by the Board of Medical Examiners with Board of Nursing coordination for CRNPs/CNMs
- Arkansas — State CSR through the Arkansas Department of Health
- Colorado — State CSR through the Department of Regulatory Agencies
- Connecticut — CSR via Department of Consumer Protection, Drug Control Division
- Delaware — CSR through the Office of Controlled Substances
- Georgia — State CSR via the Georgia Drugs and Narcotics Agency
- Idaho — Board of Pharmacy CSR
- Illinois — Illinois Controlled Substance License (ICSL) via IDFPR
- Indiana — CSR via the Professional Licensing Agency
- Iowa — Board of Pharmacy CSR
- Louisiana — CDS license via Louisiana Board of Pharmacy
- Maine — Board of Pharmacy CSR
- Maryland — CDS registration via the Office of Controlled Substances Administration
- Massachusetts — MCSR (Massachusetts Controlled Substance Registration) via DPH
- Michigan — Controlled Substance License via LARA
- Mississippi — Bureau of Narcotics CSR
- Missouri — BNDD registration via the Bureau of Narcotics and Dangerous Drugs
- New Hampshire — CSR via the Board of Pharmacy
- New Jersey — CDS via the Division of Consumer Affairs, Drug Control Unit
- New Mexico — CSR via the Board of Pharmacy
- New York — Official Prescription Program enrollment plus practitioner registration via the Bureau of Narcotic Enforcement
- North Dakota — Board of Pharmacy CSR
- Oklahoma — OBNDD registration via the Oklahoma Bureau of Narcotics
- Pennsylvania — Prescriptive authority approval with controlled substance scope through the Board of Nursing (functions as the state-level layer)
- Rhode Island — CSR via the Department of Health
- South Carolina — CSR via DHEC, Bureau of Drug Control
- Utah — Controlled Substance License via DOPL
- Wyoming — CSR via the Board of Pharmacy
That works out to roughly 25 to 28 states depending on how you count Pennsylvania and a few jurisdictions that fold the controlled substance authority into the APRN license itself rather than issuing a separate certificate.
States Where Federal DEA Is Generally All You Need
The following states do not currently require a separate state-level CSR for APRNs with an active federal DEA registration. Local hospital or employer credentialing may still ask for additional documentation, but the state itself does not issue a second certificate.
- California
- Florida
- Texas (DPS controlled substance registration was phased out; federal DEA only)
- Washington
- Oregon
- Arizona
- Nevada (for most APRN roles)
- Most remaining states not listed above
Again, verify before you rely on it. Texas in particular is a common source of confusion because the older DPS CSR existed for decades before being eliminated.
Fees, Schedules, and Filing Bodies
State CSR fees range from $0 to roughly $300+ for a multi-year term. Some states bill annually, some on a two- or three-year cycle aligned with the APRN license renewal. A few states scope the registration to specific schedules — for example, restricting APRN authority to Schedules III through V unless additional requirements are met.
The issuing agency varies: state board of pharmacy, state department of health, a dedicated narcotics bureau (Missouri BNDD, Oklahoma OBNDD), or a consumer protection division (Connecticut, New Jersey). Application formats, fingerprint requirements, and processing times are not standardized. Plan for anywhere from a few business days to 6+ weeks depending on the state.
Order of Operations: License, Then CSR, Then DEA
State CSR almost always has to follow your state APRN license issuance, the same way federal DEA does. The typical sequence is:
- Apply for and receive the state APRN license (and prescriptive authority, where it is a separate step)
- Apply for the state CSR/CDS/BNDD, listing the new state license number
- Update or add the state to your federal DEA registration
Trying to file the state CSR before the APRN license is issued will get the application rejected in most states. Trying to update federal DEA before either of the above will also fail because DEA verifies the state-level credentials.
The Most Common APRN Pitfall
The single most frequent mistake we see: APRNs assume their active federal DEA registration is enough when they relocate or pick up a per diem assignment in a new state. They start prescribing controlled substances on day one, not realizing the new state requires a CSR they have not filed. This is a board-reportable issue in several states and can show up in a future license verification or background check long after the fact.
If you are moving, locuming, or adding telehealth in a new state, check the CSR requirement before you write your first controlled substance prescription there. Our APRN licensing service includes state CSR analysis for every state we file in.
How White Glove APRN Helps
State CSR is the part of APRN licensing that most concierge services skip and most APRNs forget. We do not. When you license a new state with us, we map the full prescribing stack — APRN license, prescriptive authority, state CSR/CDS/BNDD, and federal DEA state addition — into one sequenced workflow so nothing gets filed out of order and nothing gets missed. See pricing or contact us to talk through your state list.
Sources: state board of pharmacy and board of nursing websites for each state listed above; U.S. Drug Enforcement Administration Diversion Control Division. State CSR/CDS rules and fees change without notice — always verify with the issuing agency before filing.
