A clinical license comes from a state, and it covers work in that state. A licensure compact is an agreement among states that makes a second or third state easier to reach. Each compact covers one kind of license, and the compacts don't all work the same way.
The licensing guide gives the short version for each role. This post goes further into the mechanics: what each licensure compact gives you, what you still have to get state by state, and what no compact touches.
Three ways a licensure compact can work
The compacts that matter for urgent care shifts use three different models, and the model decides what you end up holding.
- Expedited separate licenses. The physician compact speeds up the application. You still hold one license per state.
- One multistate license. The nursing compact issues a single license from your home state that's good in every member state.
- A compact privilege. The PA compact is built around a privilege to practice in another member state, granted on the strength of your existing license.
None of them changes scope of practice. What you may do in a state is set by that state's law, whichever route got you licensed there.
The Interstate Medical Licensure Compact for physicians
The Interstate Medical Licensure Compact (IMLC) covers physicians, both MD and DO. Most states take part, and the compact commission keeps the current list.
You apply once, through your State of Principal License. That state has to be a compact member where you hold a full, unrestricted license, and you need one of four ties to it: your primary residence is there, at least 25% of your practice happens there, your employer is located there, or you use it as your state of residence for federal income tax.
Eligibility goes beyond the license itself. It also takes graduation from an accredited medical school, completed accredited graduate medical education, passing each licensing exam component within three attempts, current specialty board certification, and a record with no discipline, criminal history, controlled-substance actions, or pending investigations. A physician who doesn't meet every item applies to each state the ordinary way.
Your State of Principal License verifies all of that and issues a Letter of Qualification, which is valid for 365 days. The other compact states you select then issue their licenses without repeating the verification. The cost is the compact's own fee plus each state's license fee, so the compact saves time and paperwork, not license fees.
What you hold at the end is a separate license from each state. Each one renews on its own schedule, and you follow each state's statutes and rules when you practice there.
The Nurse Licensure Compact for RNs
The Nurse Licensure Compact (NLC) works differently. An RN whose primary state of residence is a member state holds one multistate license, issued by that state, with the authority to practice in every other NLC jurisdiction. Most states are members.
Two rules follow from tying the license to where you live. A nurse who moves from one compact state to another applies for a license in the new state of residence within 60 days. And a state outside the compact still needs its own single-state license, whatever you hold elsewhere.
The NLC covers RN and LPN/VN licenses only. That limit is the one that matters most for advanced practice nurses.
NPs and CRNAs: what the licensure compacts don't cover
Nurse practitioners and CRNAs are advanced practice registered nurses (APRNs). A multistate RN license under the NLC covers the RN license and nothing above it. An APRN needs an individual APRN license in each state of APRN practice.
The APRN Compact is a separate agreement. It takes effect only once seven states have enacted it, and once implemented it would let an APRN hold one multistate license with a privilege to practice in other compact states. Until multistate APRN licenses are being issued, an NP or CRNA working in a second state applies to that state's board of nursing.
Practice authority is a second, separate layer for NPs. The American Association of Nurse Practitioners sorts state laws into three practice environments: full practice, where an NP evaluates, diagnoses, treats, and prescribes under the board of nursing's authority alone; reduced practice, where state law requires a collaborative agreement with another provider or limits at least one element of practice; and restricted practice, where state law requires supervision, delegation, or team management by another provider. An NP licensed in two states can be working under two of these at once.
PAs and the PA Licensure Compact
PAs are licensed state by state. The PA Licensure Compact is designed around a compact privilege: an authorization for a PA with a qualifying license in one member state to practice in another member state. A PA using a privilege follows the scope of practice of the state where the patient is.
A privilege is usable only once the compact commission is issuing them, and only if the state where you hold your qualifying license has joined. The commission publishes its member list and its timeline. Until privileges are available, a PA working in a second state needs that state's license.
Medical assistants
None of these licensure compacts covers medical assistants. MA requirements are set state by state, and what an MA may do is defined by state law and the clinician delegating the work. The state's medical board is the place to check before a shift in a new state.
DEA registration sits outside every licensure compact
A DEA registration is federal, but it doesn't travel across state lines. Registration depends on your authority to prescribe controlled substances under the law of the state where you practice, and a separate registration is required for a practice in each state. A practitioner registration runs for three years and is tied to a registered practice address.
So for any role that prescribes controlled substances, a new state is two applications: the state license, by compact or not, and a DEA registration for that state. The compact shortens the first and has no effect on the second.
What a licensure compact doesn't replace
A license lets you practice in the state. It doesn't credential you at a clinic. The clinic, or the platform you work through, still reviews your license, your documents, and your history before a shift. The credentialing guide covers that side.
Malpractice coverage is also separate. A policy covers the work and the places it describes, and adding a state license doesn't extend it. Where malpractice coverage gaps open in locum work goes through the questions to ask.
More state licenses also means more renewals to track. If you're weighing how many states are worth holding, managing more than one assignment without burning out covers the scheduling side of that decision.
This post explains how licensing generally works. It isn't legal advice. Compact membership and eligibility rules change, and your state board is the authority on any specific license.
Keep every license in one place
On Rediworks you add each state license to your credential wallet once and reuse it at every Rediworks facility. Every urgent care listing shows the rate and the location before you apply. Sign up to see shifts.
