You land the assignment, clear your calendar, and then credentialing flags one missing document.
Your start date slips, the facility scrambles for coverage, and you lose weeks of pay over a piece of paper you probably already own.
This checklist covers every document most facilities ask for, where to get the ones you don’t have on hand, and how far ahead to start. It’s written for physicians and advanced practice providers who already know the locum basics and want a clean, repeatable system.

What Documents Do Locum Tenens Providers Need?
The Short Answer: Most locum assignments require your CV, active state license and DEA registration, board certification, life support certifications, photo ID and NPI number, immunization and TB records, malpractice coverage proof, and at least three professional references. Hospital credentialing often takes 60 to 120 days, so gather everything before you accept an offer.
Why Start Early?
Credentialing is the step most providers underestimate. According to AMN Healthcare, hospital credentialing can run anywhere from 30 days to six months, with 60 to 120 days most typical. A clinic setting often finishes in a couple of weeks because it mostly verifies identity and certifications.
Our own read matches that range. We break down why the process drags and how to shorten it in why physician credentialing delays slow hospital operations.
Here’s our advice: start collecting documents at least 90 days before your target start date. If you’re licensed in only one state, add time for a second license. A pile of documents that’s ready in advance is the cheapest way to protect your first day.
Core Documents Every Clinician Needs
These are the documents nearly every facility asks for first.
- Education and training proof: an updated CV, diplomas, and training certificates. Not sure whether your CV needs a rewrite for locums? Read our guide on the difference between a locum CV and a resume.
- Licenses and board certification: active state medical licenses, board certification, and your DEA registration.
- Life support and specialty certifications: BLS and ACLS for most roles. PALS, ATLS, and NRP apply only when your specialty and the assignment call for them.
- Identification: a government photo ID, your NPI number, and a visa or work permit if it applies to you.
Health, Immunization, and Safety Records
Facilities protect patients and staff, so they verify your health records before you set foot on the unit. Barton Associates notes that hospitals typically want hepatitis B, MMR, varicella, and tuberculosis screening on file.
Gather these before you need them:
- Complete immunization history, including COVID-19 and flu status
- Hepatitis B, MMR, and varicella records or titers
- Recent TB test results
- Recent physical exam documentation
- Drug screen results, when the facility requires them
Requirements vary by facility and state, so ask your recruiter for the exact list before you schedule appointments.
References, Malpractice, and Background History
This is where files often stall, because other people control the timeline.
AMN Healthcare says candidates should provide at least three references, two of them from clinicians in their specialty. Pick supervisors, medical directors, or department chairs who will actually return a call, and warn them before the request lands. Recency rules differ by facility, so confirm the window with your recruiter.
You’ll also need:
- Proof of malpractice insurance, including your coverage history. If you’re moving between assignments, review why tail coverage matters for locums before your current policy ends.
- Background check authorization or results
- Disciplinary history disclosure, answered completely and consistently across every form
Regulatory, Tax, and Employment Documents
Independent contractors carry extra paperwork:
- A completed W-9
- A business license or entity documentation, if you operate through an LLC or similar entity
- Hospital credentialing packets and privileging forms
- Your contract and any related agreements
Contracts vary, so read yours closely and ask questions before you sign.
Do You Need a New License for Each State?
Yes. Each state requires its own active license. The Interstate Medical Licensure Compact can speed up the process. The IMLCC lists 44 member states plus 2 US territories, and it offers an expedited pathway for qualified physicians. It doesn’t replace state licensure. You still end up holding a license in each state where you practice.
Compare both routes in our guide to IMLC vs state licensing for locum tenens.
Organization Tips That Save You Weeks
A system beats a scramble. Here’s what works:
- Keep digital and hard copies of everything, and update them quarterly.
- Store files in cloud folders labeled by category, such as Licenses, Certifications, Health Records, and Tax.
- Track every expiration date in one place.
- Set calendar reminders 90, 60, and 30 days before each renewal.
- Scan new documents the day you receive them.

Frequently Asked Questions
Can I work locum tenens in multiple states with one license?
No. You need an active license in each state where you practice. The Interstate Medical Licensure Compact can speed up the process for physicians in its 44 member states and 2 territories, but it doesn’t replace state licensure.
How many references do I need?
Plan on at least three. AMN Healthcare recommends two from clinicians in your specialty. Ask your recruiter how recent the references must be, because facilities set their own windows.
What if I’m missing documents?
Start retrieving them now. Licenses, certifications, and references take the longest, and each one can hold up your entire file.
How far in advance should I prepare paperwork?
Start at least 90 days before your start date. Hospital credentialing commonly takes 60 to 120 days, and adding a new state license extends that timeline.
What’s the difference between credentialing and privileging?
Credentialing verifies your qualifications. Privileging authorizes the specific procedures you can perform at the facility. Facilities handle them separately, and both need to finish before your first shift. Our article on credentialing delays explains how they fit together.
