NLC: the Nurse Licensure Compact, explained

How compact privilege actually works

Nurses often describe the compact as “reciprocity.” It is not. Nothing is recognized case by case, and no board reviews your file. Instead, three conditions must all be true at the same moment. If any one fails, privilege does not exist — there is no partial credit:

1. Your primary state of residence is a member state. Not where you work, not where you were licensed years ago — where you legally live now. The compact is built entirely on this fact.
2. The license that state issued you is the multistate type. A license from a compact state is not automatically multistate — you have to have applied for one, and plenty of nurses in compact states hold single-state licenses without realising it. Check which one you hold; it takes seconds on Nursys.
3. The state you want to practice in recognizes privilege. Which means it has implemented the compact, not merely enacted it.

With all three, you may practice in that state — in person or by telehealth — while following its scope of practice and answering to its board. With only two, you generally need a license issued by the destination state, usually by endorsement. The mobility planner works through all three for a specific pair of states.

When the NLC started, and how it has grown

The original compact was implemented in 2000. It was replaced by the enhanced NLC (eNLC), which reached its 26-state enactment threshold on July 20, 2017 and went live on January 19, 2018 across 29 jurisdictions simultaneously. The enhanced version added uniform licensure requirements, including a federal fingerprint-based criminal background check — which is also why joining now takes states years rather than months. There is no federal compact statute behind any of this: each legislature enacted the model text into its own code, which is why the citation differs everywhere and why replacing the original compact left repealed sections still circulating. We publish the statute for each jurisdiction, read off its own code.

Since that launch the compact has added 11 more jurisdictions, one at a time. Growth is slow and uneven: outside the launch it has never added more than three in a year, and in 2021 it added none. The three most recent to go live:

• Connecticut — October 1, 2025
• Pennsylvania — July 7, 2025
• Rhode Island — January 1, 2024

We date every jurisdiction’s enactment and implementation from primary sources in the NLC adoption timeline — including the gap between signing the law and being able to use it, which has run as long as four years.

Who the NLC covers — and who it does not

The compact covers RN and LPN/LVN licenses. The state lists are identical for both, so RN compact states and LPN/LVN compact states are the same jurisdictions.

It does not carry APRN authority. A nurse practitioner, CRNA, CNS, or CNM needs advanced-practice authorization from every state they practice in, even holding a valid multistate RN license underneath. This is the most common expensive misunderstanding in interstate nursing, and it catches employers as often as nurses — our employer verification tool treats it as a hard stop for that reason.

It also does not reach the 13 non-compact jurisdictions — including California, which has the largest nursing workforce in the country and has not joined.

“Adopted” does not mean you can use it

3 jurisdictions have signed the compact into law but have not finished implementing it. Until they do, their residents cannot obtain a multistate license and a multistate license from elsewhere does not authorize practice there. They still appear on most published “compact states” lists, which is how nurses end up planning around a compact that is not switched on yet:

• Guam — enacted March 5, 2021, not yet in force
• U.S. Virgin Islands — enacted December 6, 2021, not yet in force
• Massachusetts — enacted November 20, 2024, not yet in force
