Your CNA license number is on your original certification card, in your state's nursing board database, or available by phone from your state health department
When you passed your Certified Nursing Assistant exam, your state issued you a license number — a unique identifier that employers, facilities, and licensing boards use to verify your credential. That number appears on your physical card, but if you've misplaced it or need it urgently, you have several ways to retrieve it without ordering a replacement card.
The fastest route depends on what you have access to right now. If you kept any paperwork from your certification, your number is likely there. If not, your state's nursing board maintains a public registry you can search online, usually for free. A phone call to your state health department takes longer but works if the online search doesn't.
Key Takeaways
- Your CNA license number appears on your original certification card, your initial paperwork from the testing agency, and your state nursing board's public registry.
- Most states allow you to search their nursing board database online by name, which returns your license number, expiration date, and current status.
- If you cannot find your number online, calling your state health department's nursing board directly will retrieve it, though wait times vary.
- Employers and facilities can also look up your license number if you provide your full name and date of birth, so you can ask them to confirm it during hiring.
- Your license number does not change when you renew; the same number stays with you throughout your career as long as you maintain active status.
Check your original paperwork and certification card
Your CNA license number is printed on the physical card your state issued when you passed your exam. If you still have that card, the number appears in the upper right or lower left corner, depending on your state's format. The card also shows your name, the date you were certified, and your expiration date.
If you've lost the card itself, check any documents you received from the testing agency or your state health department around the time you certified. These often include a letter of certification, a temporary permit, or exam results documentation — all of which typically display your license number. Look in files, email folders, or old folders from when you completed your training program.
Search your state nursing board's online registry
Every state maintains a public database of active and inactive nursing licenses, including CNA licenses. You can search this registry online using your name, and it will return your license number along with your status, expiration date, and any disciplinary history. The registry is free and requires no login.
To find your state's registry, search "[Your State] nursing board license lookup" or "[Your State] RN/LPN/CNA license verification." Most states host this on their health department website. Enter your full name as it appears on your license — if you've changed your name since certification, use both the old and new name to search. The results page will display your license number prominently.
If your state's site is difficult to navigate, the National Council of State Boards of Nursing (NCSBN) maintains a directory of state board websites at ncsbn.org. You can also call your state nursing board directly and ask for the URL to their license lookup tool.
Call your state health department or nursing board
If the online registry doesn't return results or you prefer to speak with someone, contact your state's nursing board by phone. The number is listed on your state health department website. Have your full name, date of birth, and the city where you were certified ready when you call.
Wait times vary widely depending on the state and time of day. Some boards answer within minutes; others have queues that can take 30 minutes or longer. Many state boards also accept requests by email or through an online form on their website, though responses typically take one to three business days.
Ask your employer or facility to look it up
If you need your license number quickly and you're currently employed or in the hiring process, your employer's human resources or compliance department can search your license in the state registry. They do this routinely as part of onboarding and credentialing, and they can provide you with the number in minutes.
This approach works best if you're already hired or actively interviewing. If you're between jobs, this option isn't available, but it's worth remembering for future reference — you never have to search alone if your employer has already verified your license.
Understand what your license number means and how it's used
Your CNA license number is a permanent identifier assigned by your state. It does not change when you renew your license, move to a different state, or change your name — though name changes do require you to notify your state nursing board and update your records. The number itself is public information and can be looked up by anyone, which is why employers and facilities can verify your credentials without your permission.
Your license number is what appears on background checks, credentialing forms, and facility databases. When you explore for a job, the employer uses this number to confirm you hold an active, unencumbered license. If you ever need to dispute something on your record or check your status, you'll reference this number in correspondence with your state board.
Keep your license number accessible going forward
Once you locate your number, write it down and store it somewhere you can access easily — a note in your phone, a document on your computer, or a physical card in your wallet. Many CNAs photograph their certification card front and back for this reason, which also serves as proof of certification if your physical card is damaged or lost.
If you lose your physical card and need a replacement, your state nursing board can issue a duplicate for a fee, usually between $10 and $50. The process typically takes one to two weeks. You do not need to retake your exam or recertify — a replacement card straightforward reprints your existing license information.
Frequently Asked Questions
What if I was certified in one state but now live in another?
Your original license number belongs to the state that issued it and does not transfer. If you move, you must obtain a new license in your new state, which involves either reciprocity (if your new state recognizes your old state's certification) or retesting. You can still look up your original license number in your first state's registry, but you'll need a new number in your current state.
Can I look up someone else's CNA license number?
Yes. State nursing board registries are public, so anyone can search by name to verify a CNA's license status and number. Employers, facilities, and patients' families often do this to confirm credentials. Your license number and status are not private information.
What does it mean if my license number doesn't appear in the registry?
It usually means your license has expired and you have not renewed it, or your name in the registry differs from what you searched. Check that you spelled your name correctly, including middle initials. If your license expired, you'll need to renew it through your state nursing board before you can work as a CNA again.
Do I need my license number to renew my CNA certification?
Most states ask for your license number on renewal forms, but if you don't have it, you can provide your name and date of birth instead. The state board will look up your number in their system. Having it handy makes the renewal process faster, but it's not required to complete the process.
Will my license number change if I renew my certification?
No. Your license number remains the same for your entire career, as long as you maintain active status in that state. Renewal straightforward extends the expiration date on your existing license — it does not issue a new number.
