Where to find your CNA license number right now
Your CNA license number is printed on your physical certification card, usually in the upper right corner or along the bottom edge. If you have the card in front of you, that number is what you need — it's typically a combination of letters and numbers specific to your state.
If you don't have your card or can't locate it, your state's nursing board website holds a searchable registry where you can look yourself up by name and see your license number, expiration date, and current status. This registry is public information and takes about two minutes to search.
Some states also mail a wallet card or certificate when you first pass the CNA exam, and that document includes your license number as well. If you've moved or changed your name since certification, the number stays the same — it's tied to your original certification record, not your current legal name.

Searching your state's nursing board registry
Every state maintains a public database of licensed nursing assistants. To search it, go to your state's nursing board website — search "[your state] nursing board" or "[your state] board of nursing" — and look for a link labeled "License Verification," "Licensee Search," or "Public Registry."
Enter your full legal name as it appears on your certification. Some registries also let you search by license number if you have a partial number or want to verify someone else's credentials. The search results will show your license number, the date you were certified, your expiration date, and whether your license is currently active, expired, or inactive.
If the search returns no results, double-check the spelling of your name and try searching by first and last name only, without middle initials. Some states index records differently. If you still find nothing, contact your state nursing board directly — they can confirm whether your certification was ever issued or if there's a record-keeping issue.
Contacting your state nursing board by phone or mail
If the online registry isn't working or you need your number urgently, call your state nursing board's main line. Have your full legal name, date of birth, and the city where you took your CNA exam ready. The staff member can pull up your record and read your license number to you over the phone.
Most state boards answer calls during business hours Monday through Friday. Wait times vary — some answer within minutes, others may put you on hold. If you prefer written confirmation, you can also mail a request to the board with your name and date of birth, and they will send you a copy of your license record by mail within one to two weeks.
A few states charge a small fee for written verification (usually $5 to $15), but phone lookups are free. Ask the staff member whether you need to pay before they process your request.
What to do if your card is lost or damaged
A lost or damaged card doesn't affect your license status — your certification remains active as long as you haven't let it expire. You can continue working while you replace it. To get a replacement card, contact your state nursing board and request a duplicate. Most states charge $10 to $25 for a replacement card and mail it within two to four weeks.
Some states let you request a replacement online through their licensing portal; others require you to mail or fax a form. Your state board's website will have the replacement card request form and instructions. You'll need to provide your license number (which you can find through the registry) and proof of your current address.
In the meantime, if an employer or facility needs proof of your license, print a copy of your registry search result or request a letter of verification from the state board. Both are legally acceptable proof of active certification.
Understanding your license number format
CNA license numbers vary by state in length and format. Some states use a straightforward numeric sequence (like 123456), while others mix letters and numbers (like CA-12345-A). A few states include your birth year or initials in the number. The format itself doesn't matter for your purposes — what matters is that the number on your card matches the number in the state registry.
Your license number is not the same as your Social Security number, your driver's license number, or any other ID. It's unique to your CNA certification in that state only. If you become certified in a second state, you'll receive a different license number for that state, even though you're the same person.
Some employers ask for your "certification number" or "registration number" — these terms mean the same thing as license number in the context of CNA credentials. Write down the number exactly as it appears on your card or in the registry, with all letters and numbers in the correct order.
When you need your license number for work or renewal
Your employer will ask for your CNA license number when you're hired, and you'll need it again if you renew your certification. Keep a photo or photocopy of your card in a safe place, or write the number in a document you can access easily. Many CNAs take a photo of their card with their phone for quick reference.
When your certification is about to expire, your state board may send you a renewal notice by mail with your license number printed on it. If you don't receive a notice, you can still renew by contacting the board or using their online renewal portal — you'll enter your license number to pull up your record and complete the renewal process.
Some states require you to renew every two years, others every three years. Check your card's expiration date or search the state registry to see when your renewal is due. Renewing before your card expires keeps your certification active without a gap in coverage.
Frequently Asked Questions
Can I look up someone else's CNA license number?
Yes. State nursing board registries are public, so you can search any licensed CNA by name. This is useful if you need to verify a coworker's credentials or check whether someone claiming to be a CNA is actually licensed. Search results show the person's license number, status, and expiration date.
What if my name has changed since I got my CNA license?
Your license number stays the same. Search the registry using your current legal name, and your record should appear. If it doesn't, try searching under your former name. Contact the state board if you need help updating your name in their system — some states require you to submit a name change form.
Do I need my license number to work as a CNA?
Your employer needs your license number for their records and to verify your certification with the state board. You don't need to memorize it, but you should know where to find it quickly. Keep a copy of your card or a photo of it accessible at all times.
What if the registry shows my license as expired?
Contact your state nursing board when ready. If your license expired, you cannot work as a CNA until you renew it. The board can tell you the renewal important date and walk you through the renewal process, which usually involves paying a fee and sometimes completing continuing education hours.
Can I get my license number without contacting the state?
Yes — search your state's public registry online using your name. This is the fastest way and requires no phone call or paperwork. If the online search doesn't work, your physical card is your next option. Contacting the state board is your last resort and usually takes longer.
