What counts as a valid professional license or certificate
A valid professional license is one that is current, issued by the government body or accredited organisation that has authority over your field, and has not been suspended or revoked. A certificate is typically a credential showing you completed training or passed an exam in a specific skill — it may or may not be required by law to work in that field.
The difference matters because some forms, job applications, and government programs ask specifically for licenses (which usually carry legal weight) while others accept either. A nursing license issued by your state's board of nursing is valid. A CPR certification from the American Red Cross is valid. A certificate of completion from an online course you took last month may not be, depending on what the form is asking for.
Validity also depends on whether you have renewed it on time. Most professional licenses expire on a set date and require renewal — sometimes every one, two, or three years depending on the field. If your license has expired and you have not renewed it, it is no longer valid, even if you still have the physical document.
Key Takeaways
- A valid license must be current, issued by the official body for your field, and not suspended or revoked — check your state or national board's website to confirm status.
- Certificates from accredited training programs or exam bodies (like nursing assistants, electricians, or IT certifications) count as valid if they are current and issued by a recognised organisation.
- Expired licenses and certificates are not valid, even if you completed the training or passed the exam — renewal dates vary by field and state.
- You can verify most professional licenses online through your state licensing board or the national organisation that oversees your profession.
- Keep copies of your current license or certificate in a safe place, along with the renewal date so you do not miss important date.
How to check if your license is currently valid
Most states and professions have a public database where you can look up whether a license is active. Start by searching "[your state] [your profession] license lookup" — for example, "California nursing license lookup" or "Texas electrician license verification." This will usually take you to your state's licensing board website.
Enter your name, license number, or both, depending on what the database asks for. The result will show whether your license is active, expired, suspended, or revoked. If you do not have your license number, look at the physical license itself — it is usually printed near the top or bottom. If you cannot find the database or your state does not have one online, call your state's licensing board directly. The phone number is on your license or on the board's website.
For national certifications — such as CompTIA A+, AWS certifications, or nursing assistant credentials — go to the issuing organisation's website. CompTIA, Amazon Web Services, and the certifying body for your specific credential will have a verification tool. You may need your certification number or the email address you used when you earned it.
Types of licenses and certificates that count as professional credentials
Government-issued licenses are the strongest form of professional credential. These include nursing licenses, teaching licenses, contractor licenses (plumbing, electrical, HVAC), real estate licenses, and law licenses. Each is issued by a state board or similar authority and is required by law to work in that field.
Accredited certifications are the next tier. These are issued by recognised organisations and often require passing an exam or completing a formal program. Examples include Certified Nursing Assistant (CNA), CompTIA Security+, AWS Solutions Architect, Project Management Professional (PMP), and HVAC technician certifications. These are widely recognised and often required or preferred by employers, even if they are not legally required to work.
Trade and apprenticeship certificates are issued after completing a formal apprenticeship or trade program. These cover fields like welding, carpentry, plumbing, and electrical work. Some are issued by unions, some by community colleges, and some by state programs. They count as valid professional credentials if issued by an accredited program.
Continuing education certificates show you completed training in a specific area — for example, a CPR renewal certificate or a professional development course. These are usually valid only for the time period stated on the certificate and are often required to maintain a primary license.
What to do if your license or certificate has expired
If your license has expired, you cannot legally work in that field until you renew it. The renewal process varies by profession and state. Most licenses can be renewed online through your state's licensing board website. You will usually need to pay a renewal fee, which ranges from under $50 to several hundred dollars depending on the field.
Some professions require continuing education hours before you can renew. For example, many states require nurses to complete a certain number of continuing education credits every renewal cycle. Check your state board's website or call them to find out what is required for your specific license before you start the renewal process.
If you have lost your physical license or certificate, you can request a replacement or a verification letter from the issuing body. This is usually faster and cheaper than renewing if your license is still current. Go to your state board's website or call them to ask how to request a duplicate.
Where to find your license or certificate information
Your physical license or certificate should have the following information printed on it: your name, the type of license or credential, the issue date, the expiration date, your license number, and the name of the issuing body. Keep this document in a safe place — a filing cabinet, a safe, or a scanned copy in cloud storage.
If you cannot find your physical copy, you can usually read a digital copy or request one from the issuing body. Most state licensing boards allow you to print a verification letter or digital copy of your license directly from their website. For national certifications, log into your account on the issuing organisation's website — CompTIA, Pearson VUE, Prometric, and others allow you to read or print your certificate.
Write down your renewal date somewhere you will see it — a calendar, a phone reminder, or an email to yourself. Many licensing boards send renewal notices, but not all do, and missing a renewal important date can result in your license expiring without warning.
Professional licenses and certificates by field
Healthcare professions require state licenses: registered nurses (RN), licensed practical nurses (LPN), physicians, dentists, and therapists all need licenses issued by their state board. Certifications like CNA, phlebotomy, and medical coding are also common and widely recognised.
Skilled trades require either a license or a certificate depending on the state and the specific trade. Electricians, plumbers, HVAC technicians, and welders typically need a license or apprenticeship certificate. Some states require a journeyman or master license after apprenticeship.
Education requires a teaching license issued by your state's department of education. Some states also recognise national certifications like National Board Certification (NBC) as additional credentials.
Information technology and business certifications are usually not required by law but are widely recognised by employers. CompTIA, Microsoft, AWS, Google, and Cisco all issue certifications. These are valid as long as they are current — many IT certifications expire after three years and require renewal or retesting.
Real estate, insurance, and financial services all require licenses issued by your state. These are legal requirements to work in the field and must be renewed on schedule.
Frequently Asked Questions
Can I use an expired license or certificate on a job process?
No. If a form asks for a valid professional license or certificate, an expired one does not meet that requirement. You can mention the credential and note that you are in the process of renewing it, but you cannot claim it as a current credential. Some employers may still consider you if you are close to renewal, but that is their choice.
What if I earned a certificate from an online course — does that count?
It depends on what the form is asking for and who issued the certificate. A certificate from an accredited program or a recognised organisation (like Coursera with a university partner, or CompTIA) may count. A certificate of completion from a random online course probably will not. If you are unsure, contact the organisation asking for the credential and ask whether your specific certificate is acceptable.
How do I know if my certifying organisation is accredited?
Search for "[organisation name] accreditation" or "[organisation name] recognised certifications." Most major certifying bodies list their accreditation status on their website. You can also check with your state licensing board or your industry association — they usually maintain a list of recognised certifications in your field.
Do I need to carry my physical license with me at work?
That depends on your field and your employer. Some professions require you to display your license at your workplace. Others only require you to have it available if asked. Check your state board's rules or ask your employer. Either way, keep a copy at home and consider keeping a digital copy on your phone.
What happens if my license is suspended or revoked?
You cannot work in that field until the suspension is lifted or, if it is revoked, until you go through the process to earn the license again. If you believe a suspension or revocation is wrong, you have the right to appeal. Contact your state licensing board for information about the appeal process and what evidence you need to provide.
