Your CNA certification number is the unique identifier your state nurse aide registry uses to confirm you completed training, passed the competency exam, and are legally allowed to work as a certified nursing assistant. Employers, staffing agencies, and state surveyors will ask for it before your first shift. Yet many CNAs do not memorize the number, and the original card goes missing inside a drawer somewhere. The good news is recovery is usually free, fast, and self-service. This guide walks you through finding your number in any state.

Before you start, understand the structure. Every state runs its own CNA registry, and the number is generated when your active listing is created. The format varies: California uses a 7-digit CNA number issued by CDPH, Florida uses a 6-digit certificate number from the Board of Nursing, Texas uses the NAR identifier, and many states tied to Credentia or Prometric reuse the candidate ID from your exam record. There is no national CNA number, so the lookup tool you need depends entirely on where you trained and tested.

The fastest path is usually the public registry website for the state that certified you. Most state health departments and nursing boards publish a free lookup that accepts your last name plus date of birth or your social security number. Within a few clicks you will see your full name, certification number, expiration date, and any flags on your record. If you trained in one state and now work in another, you must search the state that originally issued the certificate, not the state where you currently live, unless you have already filed reciprocity paperwork.

Pull out a piece of mail or your training school records and confirm which state you registered in. Then visit the official CNA license lookup hub for state-by-state direct links. Most lookups load in seconds. If the registry is offline or shows no record, do not panic. State systems are taken down for maintenance overnight and on weekends, and listings sometimes take 4–6 weeks to appear after you pass the exam. Wait 24 hours, try again, then call the registry hotline if the record still does not appear.

Credentia is the testing vendor used by roughly 25 states, and it is one of the most common places to recover your number. Log in to your Credentia CNA 365 candidate account using the email you registered with for the state exam. The dashboard displays your candidate ID, exam results, and the certification number once your state has uploaded the active listing. If you cannot remember which email you used, the customer service line is 855-499-9698 and agents can verify your identity using your social and date of birth, then resend login credentials within minutes.

Prometric handles the CNA exam in several other states, including Maryland, Virginia, West Virginia, and parts of the Midwest. After passing, Prometric issues a score report with a candidate ID. That ID is not always identical to your state certification number, but it is the key your state registry will use to find you. Log in to the Prometric candidate portal, download the score report PDF, and you will see the identifier on the top right. Save a copy to your phone so you have it ready when an employer asks during onboarding.

Pearson VUE, D&S Diversified Technologies, and Headmaster operate exam delivery in the remaining states. Each vendor maintains a candidate portal where you can pull score reports and ID numbers. The login email is the one you used when scheduling the exam. If you signed up through your training school, ask the school administrator for the original confirmation email — they often have it on file. Never pay a third-party site that claims to look up your number for a fee. The official vendor accounts are always free, and the state registry never charges to verify your own record.

California CNAs use the CDPH (California Department of Public Health) verification page. Enter your last name and date of birth and the system returns your CNA number, expiration date, and any open complaints. The system is authoritative — CDPH is the only entity that issues California numbers. For details on the state's renewal cycle and how to lift a lapsed status, the California lookup guide covers the full process. Note that California numbers stay with you for life, so even if your certification has expired, the number is still recoverable through CDPH.

Florida runs lookups through the Department of Health MQA search portal. Choose "Certified Nursing Assistant" from the profession menu, enter your last name, and the certificate number appears next to your listing. Florida numbers are 6 digits prefixed with "CNA". Texas uses the Texas Health and Human Services Nurse Aide Registry, accessible from the HHSC website with a name and date of birth search. Illinois publishes results through the IDPH Health Care Worker Registry, and the Illinois registry guide explains the multi-step search.

New York requires a slightly different approach. The state contracts with Prometric, so your initial number is your Prometric candidate ID. Once the state Department of Health adds you to the New York Nurse Aide Registry, you also receive a state-issued certification number. Search by name on the public registry. North Carolina, Georgia, and Ohio all have free online lookups. Missouri's registry is operated through the Family Care Safety Registry, and the Missouri registry walkthrough outlines the exact search steps and what to do if your record is still pending after testing.

Cannot find your number anywhere online? Call the registry. Every state publishes a CNA hotline, and an agent can verify you in two minutes using your social, date of birth, and the address on file. California CDPH is reachable at 916-327-2445. Florida Board of Nursing answers at 850-245-4125. Texas HHSC Nurse Aide Registry is 800-452-3934. Credentia customer service at 855-499-9698 covers state exam questions. Have your training certificate and a government photo ID nearby. Most agents will email or mail a verification letter within 1–2 business days.

If you completed training but never see your number appear in the registry, the issue is almost always paperwork. Your school may not have submitted final documentation, your exam vendor may not have transmitted scores yet, or the state may have an open data entry queue. Contact your training program first — they have a direct line to the state and can often push your file through. If the school is closed, request your CNA license directly from the state with proof of training (transcripts, certificate of completion, or attendance records signed by the program director).

Lost the original certificate but still have your number? Order a duplicate. Most states issue replacement cards for $10–$25 with a 2–4 week turnaround. Some now print on demand and email a PDF the same day. The request form is usually buried on the registry website under a heading like "Duplicate Certificate" or "Verification of Certification." Pay with a credit card. Once received, photograph both sides and save the image to your phone. Cloud storage means you will never lose access to the number again, even if the physical card disappears in a laundry pocket.

Moving to another state? Your CNA number does not transfer automatically. You must file reciprocity paperwork through the new state and prove your original record is active and free of substantiated abuse findings. The new state will issue its own certification number, and your old number stays on file with the issuing state. To compare requirements, the license verification page shows which states honor each other's certifications and how long reciprocity takes — usually 30–90 days from the date the state receives your verification packet.

Watch the expiration date next to your number. Most states require renewal every 2 years and proof that you worked at least 8 hours of paid nurse aide duties during the cycle (the exact minimum is 8 hours in some states, 100 in others). If you do not meet the work-hour requirement, you may keep the number but the certification goes inactive — and reactivation often means retraining and retesting. Setting a calendar reminder 90 days before expiration is the easiest way to protect the credential you worked hard to earn.

Got a different number every place you look? You probably have multiple records. CNAs who tested in two states or had a name change after marriage frequently end up with overlapping listings. Call the state and ask them to consolidate. Provide both numbers, your full legal name history, and your date of birth. Within a few weeks the older record is usually retired in favor of the current one, and only one active number remains. For step-by-step assistance, the national CNA registry hub outlines the merger process in plain English.

Employers verify your number before your first paycheck clears. Hospitals and skilled nursing facilities are required by federal law (the Omnibus Budget Reconciliation Act of 1987) to confirm you appear on the state registry in "active and in good standing" status. If your number is correct but your status shows "expired," "lapsed," or "pending," the offer of employment can be rescinded. Always check your own record a week before any new job starts. A 5-minute self-verification today prevents a 5-day onboarding delay tomorrow.

Common myths to ignore: there is no federal CNA database, the National Council of State Boards of Nursing does not maintain a nationwide CNA registry, and a CNA number is not the same as an RN or LPN license number. Do not confuse your number with the NPI (National Provider Identifier) — most CNAs are not eligible for NPIs unless they bill Medicare directly, which is rare. If a recruiter asks for an NPI and you are a CNA, clarify the request. They likely want your state CNA number, not the federal provider ID.

Security tip: treat your CNA number like a partial Social Security number. It is not as sensitive as your SSN, but it does identify you in healthcare staffing systems and can be used by bad actors to commit credential fraud. Never share it on social media, never email it on an unencrypted link, and never give it to a third-party staffing app that has not verified its legitimacy. Legitimate staffing agencies and travel CNA firms verify directly with the state registry — they do not need you to paste the number into a chat window.

One last shortcut: many CNAs find their number printed on the official certificate, the wallet card that came in the mail after passing the exam, the back of an old paystub from a previous nursing employer, or in their CNA exam prep portal account. Before you call the state, dig through old paperwork. A friend or family member who saw you celebrate passing the exam may have kept a photo of the card. Five minutes of searching can save an afternoon of phone calls and verification emails.

If you want to keep moving forward in your career, knowing your CNA number is just the first step. The next step is renewal, advancement to LPN or RN, or specialty certifications like restorative care or hospice. The CNA careers guide walks through pay ranges, where to work for the best advancement opportunities, and how to leverage your current credential to climb into higher-paying healthcare roles. Lock down the number today, then plan the next move tomorrow.

What if you tested under a former name? Maiden names, hyphenated last names, and legal name changes after marriage or divorce are a common reason CNAs cannot find themselves in the registry. Search the state lookup using the name you used on the day of the exam, not your current name.

If the registry only allows current-name searches, call the hotline and ask the agent to search by social security number instead. Once you locate the record, file a name change request with the state. Most states require a certified copy of the marriage license or court order plus a small administrative fee.

Travel CNAs working with multiple staffing agencies should keep a credential file with their certification number, expiration date, registry verification screenshot, training school certificate, BLS card, immunization records, and recent TB test. Upload everything to a cloud folder you control. Staffing apps come and go, but your credentials follow you for a career. Pair the file with quick links to your state lookup so any new agency recruiter can confirm your active status in under two minutes. The CNA hospital jobs page covers what hospital systems specifically ask for during the credentialing review.

Bilingual CNAs and immigrants who trained internationally face an extra step. Foreign nurse aide credentials do not transfer directly to a US state registry. You must complete a state-approved CNA training program (75–120 hours depending on the state), pass the written and skills competency exam, and apply for a state-issued number just like any first-time candidate.

Equivalency for foreign LPNs and RNs is a different process handled by state nursing boards, not the nurse aide registry. Once you earn your US CNA number, you can search for and verify it through any state's standard lookup tool.

Worried about a complaint or abuse finding on your record? State registries show substantiated findings publicly because federal OBRA-87 rules require transparency. If a finding appears next to your number, contact the state registry to learn the appeal process. Some findings can be expunged after a waiting period, while others remain permanent. The CNA license overview outlines your due process rights when a complaint is filed. Always respond to registry inquiries within the deadline listed in the notice — failing to reply is treated as agreement with the complaint and can result in permanent loss of certification.

Some employers and continuing education providers use a clearing house called the Nursys QuickConfirm service, but this only covers RNs and LPNs, not CNAs. For CNAs the only authoritative source remains the state nurse aide registry.

If a recruiter or HR system asks you to enter your number into Nursys, gently correct them and provide the state lookup URL instead. The same applies to the National Practitioner Data Bank (NPDB), which covers physician and advanced practice records but not nursing assistants. Direct the requester to the appropriate state CNA registry for fast, free, accurate verification.

Planning to renew? Mark the date 90 days before your expiration on the calendar. Most states open renewal windows 60 to 90 days early and process applications faster than during the rush at expiration. Gather your paid CNA work hours documentation (paystubs, employer letters), continuing education certificates if your state requires CEU credit, and your renewal fee. Submit online through the registry portal whenever possible. The CNA license renewal guide breaks down state-specific requirements, fees, and the exact documents each registry accepts during the renewal cycle.

Bottom line: finding your CNA certification number should take 10 minutes or less. Start with the state registry website that issued the credential. Use last name plus date of birth as your search.

If nothing appears, log in to your exam vendor account (Credentia, Prometric, or Pearson VUE). If both options fail, call the state hotline and bring your social, date of birth, and government photo ID to the call. Save the number to your phone, your cloud drive, and your email signature so the next employer can verify you in two clicks. You earned this credential — keep it visible and active.
