To get a DEA license in California, you need an active California professional license that authorizes you to prescribe controlled substances, a one-time attestation that you have met the MATE Act training requirement, and a completed DEA Form 224 filed online with an $888 fee. Approval generally takes four to six weeks. Once your certificate arrives, California adds a step most new registrants miss: you must register with the state’s CURES prescription drug monitoring database before you start prescribing.
Who Needs a DEA Registration in California
If your California license lets you prescribe, administer, or dispense Schedule II through V controlled substances, you need a DEA registration before you can actually do any of those things. That covers physicians, dentists, podiatrists, and veterinarians. It also covers nurse practitioners, physician assistants, certified nurse-midwives, nurse anesthetists, and clinical nurse specialists who hold the appropriate state prescribing or furnishing authority.1Drug Enforcement Administration. Mid-Level Practitioners Authorization by State
One boundary worth noting up front: Schedule I substances (research chemicals and the like) require a separate research-specific DEA registration with its own protocol approval. The practitioner registration described here is for Schedules II through V only.
Another detail that catches people: each physical location where you store, dispense, or administer controlled substances needs its own registration and its own fee. Two offices means two applications.
The California License You Need First
Federal law ties DEA registration to state authority. You cannot get a DEA number unless California has granted you the legal authority to handle controlled substances.2GovInfo. 21 USC 823 – Registration Requirements In California, that authority comes from your professional license itself. The state does not issue a separate controlled substance credential, so you can leave the state controlled substance license field on the DEA form blank.3Drug Enforcement Administration. Practitioner’s State License Requirements
Your license must be active, unrestricted, and must specifically authorize prescribing or furnishing controlled substances. For physicians and dentists, that authority is built into the license. Nurse practitioners need a furnishing number from the California Board of Registered Nursing first.4California Board of Registered Nursing. Frequently Asked Questions Regarding Nurse Practitioner Practice Physician assistants need equivalent authorization through the Medical Board.
Completing the MATE Act Training Requirement
Before you file, you need to satisfy the Medication Access and Training Expansion (MATE) Act training requirement. It is a one-time attestation: you check a box on the DEA form confirming you qualify under one of three pathways.5Substance Abuse and Mental Health Services Administration. Training Requirements (MATE Act) Resources
- Eight hours of approved training on treating and managing patients with opioid or other substance use disorders, which can be accumulated across multiple sessions.
- Current board certification in addiction medicine or addiction psychiatry from the American Board of Medical Specialties, the American Board of Addiction Medicine, or the American Osteopathic Association.
- Graduation within the past five years from a qualifying U.S. medical, advanced practice nursing, or physician assistant program whose curriculum included substance use disorder training.
The DEA does not ask for proof at the time of application. You simply attest. Keep documentation of your training or certification on hand in case the DEA later asks you to verify it.6Drug Enforcement Administration. Opioid Use Disorder – MATE Act Q&A
Filing DEA Form 224
New practitioner applications must be filed online through the DEA’s Diversion Control Division registration portal. Paper is not accepted. Have the following ready:
- Your Social Security number.
- Your California professional license number, plus your furnishing number if you are a nurse practitioner.
- The physical street address of your practice location. P.O. boxes are not accepted.
- The schedules you intend to handle, which must fall within your California scope of practice.
Check that the address on your application matches the address on file with your state licensing board. Mismatches are one of the most common reasons applications stall for additional review.
Fee, Exemptions, and Processing Time
The practitioner registration fee is $888, paid in full at submission, and covers a three-year registration period.7Federal Register. Registration and Reregistration Fees for Controlled Substance and List I Chemical Registrants There is no installment option and no proration.
Federal, state, and local government employees acting in their official capacity are exempt from the fee. That covers practitioners at public health departments, VA hospitals, and similar government-operated facilities. The exemption does not reach contractor-operated institutions, even those serving government patients.
Expect roughly four to six weeks for processing. Some applications take longer when the DEA has to verify state license information or resolve discrepancies. When approved, you receive a Certificate of Registration (DEA Form 223) and your DEA number. Keep the certificate accessible at your registered location.
Registering With CURES After You Get Your Certificate
This is the California-specific step that catches new registrants. State law requires every practitioner authorized to handle Schedule II through V controlled substances to register with the Controlled Substance Utilization Review and Evaluation System (CURES) as soon as the DEA certificate issues.8California Legislative Information. California Code HSC 11165.1 CURES is California’s prescription drug monitoring program, run by the state Department of Justice. You register online through the DOJ’s CURES portal using both your state license number and your new DEA number.9California Department of Justice. Controlled Substance Utilization Review and Evaluation System
Registration is only half the obligation. Before prescribing a Schedule II, III, or IV controlled substance to a patient for the first time, you must pull that patient’s controlled substance history for the preceding twelve months. If you keep prescribing as part of ongoing treatment, you must check again at least once every six months.10California Legislative Information. California Health and Safety Code 11165.4
The consultation must occur no earlier than twenty-four hours (or the previous business day) before you write the prescription. If a staff member runs the report, document in the patient’s chart that you reviewed it within twenty-four hours of prescribing. Failing to register or consult CURES as required can trigger discipline from your licensing board.
Keeping Your Registration: Security, Records, Inventory
Holding a DEA registration carries ongoing compliance duties well beyond writing prescriptions. The DEA audits for these, and violations can cost you your registration.
Physical Security
All Schedule II through V controlled substances at your practice must be stored in a securely locked, substantially constructed cabinet.11eCFR. 21 CFR Part 1301 – Security Requirements Pharmacies and institutional practitioners may instead disperse controlled substances through general drug stock, but individual practitioners generally need to keep them locked up.
Recordkeeping
You must maintain records of every controlled substance you receive, dispense, or administer. Keep them at your registered location, available for DEA inspection, for at least two years.12eCFR. 21 CFR 1304.04 – Maintenance of Records and Inventories
Biennial Inventory
Every two years, conduct a full inventory of all controlled substances on hand. It must be in written, typed, or printed form and must note whether it was taken at the opening or close of business. Each registered location gets its own inventory.13eCFR. 21 CFR 1304.11 – Inventory Requirements For opened containers of Schedule I or II substances, you need an exact count. For Schedule III through V in opened containers, an estimate is fine unless the container holds more than 1,000 tablets or capsules, in which case you count exactly.
Reporting Theft or Loss
If controlled substances are stolen or missing, notify your local DEA field division office in writing within one business day of discovery, then file DEA Form 106 online within forty-five days.14Drug Enforcement Administration. Theft/Loss Reporting Late reporting is itself a compliance violation.
Renewing, Moving, and Transferring Your License
Renewal
Your DEA registration is valid for three years. The DEA sends electronic renewal reminders to your email on file at 60, 45, 30, 15, and 5 days before expiration. No paper notices go out.15Drug Enforcement Administration. Diversion Control Division Registration Renew using DEA Form 224a through the same online portal.
Do not let it lapse. Federal law prohibits handling any controlled substances under an expired registration, even for one day. The DEA allows reinstatement within one calendar month after expiration, but during that gap you cannot legally prescribe, dispense, or administer. Miss the one-month window and you must file a new application from scratch.
Changing Your Practice Address
If you move within California, submit a modification request to the DEA Registration Unit, either in writing or through the online portal, with your current registration number, the new address, and your signature.16eCFR. 21 CFR Part 1301 – Modification, Transfer and Termination of Registration Form 106 is only for theft and loss, not address changes.
Moving Out of State
If you leave California for another state, you need to transfer your DEA registration. You must first hold a valid professional license in the new state, with controlled substance authority if that state requires a separate credential. Then request the transfer through the DEA’s online portal. A DEA registration can only be tied to one state at a time. Processing usually takes a few days to a few weeks.
Military servicemembers and their spouses who relocate on orders get an exception under the Servicemembers Civil Relief Act: they can transfer their DEA registration to a new state without first getting a new state license, as long as the existing license remains active and in good standing.17Drug Enforcement Administration. Professional State License Exception for DEA-Registered Servicemembers and Their Spouses Who Relocate to a Different State Because of Military Orders
Prescribing by Telehealth Through 2026
If you plan to prescribe controlled substances through telehealth, the COVID-era flexibilities remain in effect. The DEA extended them through December 31, 2026, letting practitioners prescribe Schedule II through V controlled substances via audio-video telemedicine without an in-person evaluation.18Drug Enforcement Administration. DEA Extends Telemedicine Flexibilities to Ensure Continued Access to Care For opioid use disorder medications in Schedules III through V, such as buprenorphine, audio-only encounters are also permitted. Every prescription must still have a legitimate medical purpose, come from a licensed practitioner, and comply with federal and California law. Permanent telemedicine prescribing rules, including a proposed special telemedicine registration, remain in development.
What Can Cost You Your DEA License
The DEA can deny a new application or revoke an existing registration on five grounds:19Office of the Law Revision Counsel. 21 USC 824 – Denial, Revocation, or Suspension of Registration
- Material misrepresentation on the DEA application.
- A felony conviction under federal or state law related to controlled substances.
- Loss of state authorization, meaning California has suspended, revoked, or denied your professional license so that you can no longer handle controlled substances under state law.
- Acts against the public interest, a broad category covering things like consistent recordkeeping failures, diversion, or prescribing outside legitimate medical purposes.
- Exclusion from Medicare or state healthcare programs.
Before revoking or suspending, the DEA typically issues an order to show cause, giving you a chance to respond and submit a corrective action plan. In cases involving imminent danger to public health, where the DEA finds a substantial likelihood of death, serious harm, or drug abuse if you keep practicing, it can issue an immediate suspension without that process.
The loss-of-state-authorization ground is the one that affects California practitioners most often. When the Medical Board, Dental Board, or Board of Registered Nursing acts against a license, the DEA almost always follows. Protecting your state license is functionally the same as protecting your DEA registration.
