Which Licenses Are Required for My Career?

If you are considering a career, changing occupations, or applying for a new job, you may need more than a degree or professional certification. Some careers require an occupational license before you can legally perform the work.

The important part is that there is no single list of licenses required for every career in the United States. Licensing requirements depend on the occupation, the state where you work, and sometimes the specific responsibilities you will perform.

CareerOneStop explains that occupational license requirements vary by state and provides a License Finder that allows job seekers to search by occupation and state.

That means the answer to “Do I need a license?” should never be based solely on your job title. You should verify the requirements for the exact occupation and location where you intend to work.

Quick Answer: Which Careers Require a License?

Many careers do not require an occupational license, while others legally require one before you can practice. Licensed occupations are especially common in healthcare, education, personal care, transportation, construction, skilled trades, finance, and other regulated professions.

Examples of occupations that may require a professional license include:

This does not mean every job within these broad fields has identical requirements. Licensing rules can differ substantially by state and occupation.

For example, CareerOneStop specifically identifies healthcare occupations and personal-care occupations such as dental assistants, emergency medical technicians, barbers, and cosmetologists among fields where licensing can apply.

What Is an Occupational License?

An occupational license is a government-issued credential that provides legal authority to perform a particular occupation.

The U.S. Bureau of Labor Statistics distinguishes a license from a professional certification based primarily on who issues the credential and what authority it provides. A license is issued by a government agency and gives the holder legal authority to work in an occupation. A certification is generally issued by a nongovernmental organization and demonstrates knowledge or competency but does not itself provide legal authority to practice.

This distinction matters because you can sometimes work in a profession without a certification but cannot legally perform certain regulated work without the required license.

License vs. certification

License Certification
Usually issued by a government agency Usually issued by a professional or industry organization
Can provide legal authority to practice Generally demonstrates knowledge or competency
May be legally required Usually voluntary
Requirements vary by jurisdiction Requirements depend on the certification organization
May require education, exams, experience, or other criteria May require an examination, education, experience, or training

BLS also notes that a person can hold both a license and a certification. One does not necessarily replace the other.

Why Licensing Requirements Vary by State

The biggest reason job seekers get confused about licensing is that the United States does not have one universal occupational licensing system.

States establish licensing requirements for many regulated occupations, and the requirements can differ from one state to another. CareerOneStop specifically states that licensing rules are set by states and can vary by state.

This creates an important scenario for people moving for work.

Imagine that you are a licensed professional in Georgia and receive a job offer in another state. You should not assume that your Georgia license automatically allows you to practice in the new state.

You may need:

The exact requirements depend on the profession and state.

How to Find Out If Your Career Requires a License

Do not rely on a generic Google search or an old article when determining whether you need a license. Licensing requirements can change, and state rules are not necessarily identical.

Use this process instead.

Step 1: Identify your exact occupation

Your job title may not be the same as the occupation used by the licensing agency.

For example, an employer may advertise a position using a title such as “Project Engineer,” “Financial Advisor,” or “Clinical Specialist,” while the state licensing agency uses a different occupational classification.

Start by identifying the actual duties you will perform, not just the title on the job posting.

Step 2: Identify the state

Next, determine where you will physically perform the work.

For most state-regulated professions, the relevant state is more important than where your employer's headquarters are located.

If you are working remotely, the licensing analysis can become more complicated depending on the profession and the location of the client, employer, or professional activity.

Step 3: Check the state's licensing agency

The safest source is the government agency responsible for regulating your occupation.

CareerOneStop's License Finder can help you identify the relevant license and the state agency responsible for issuing it. Its database includes license names, descriptions, issuing organizations, and related occupational information.

Step 4: Check the actual license requirements

Finding the name of a license is only the beginning.

Read the requirements carefully. The licensing process may require a combination of:

BLS explains that licensing criteria can include education, certifications, educational certificates, assessments, apprenticeships, and work experience, depending on the occupation.

Careers That Commonly Require Professional Licenses

Although requirements vary by state, some broad career categories are much more likely to involve occupational licensing.

Healthcare

Healthcare contains many licensed occupations because professionals can have significant responsibility for patient safety and care.

Depending on the occupation, licensing can apply to physicians, nurses, pharmacists, dentists, physical therapists, occupational therapists, social workers, and many other healthcare professionals.

Do not assume that every healthcare position requires a license. Administrative, technology, research, support, and other positions within healthcare organizations may have completely different requirements.

Education

Teachers and certain education professionals commonly need state authorization to work in public education.

States may use different terminology, including “certification,” for credentials issued by government agencies. BLS notes that terminology can sometimes be confusing because states may call a teacher credential a certification even though BLS classifies a government-issued credential that provides legal authority as a license.

Law

Attorneys must generally be licensed by the appropriate jurisdiction before practicing law. The specific requirements depend on the jurisdiction.

If you are considering practicing law in another state, never assume that passing one state's bar examination automatically gives you the right to practice elsewhere.

Real Estate

Real estate professionals commonly need state-specific licenses. The exact license depends on the activities performed and the state's regulatory structure.

Skilled Trades

Electricians, plumbers, HVAC professionals, contractors, and other skilled trades can be subject to licensing requirements.

Requirements can vary significantly by state and sometimes by city or county. A person performing certain work under supervision may have different requirements from someone independently contracting with customers.

Personal Care

Barbers, cosmetologists, estheticians, and related professionals can be subject to state licensing requirements.

CareerOneStop specifically identifies personal-care occupations such as barbers and cosmetologists as examples of fields where occupational licensing can apply.

Transportation

Some transportation jobs require government-issued credentials. Commercial drivers, for example, may need a Commercial Driver's License, or CDL, depending on the vehicle and work performed.

Other transportation occupations can have additional endorsements or requirements.

What About Technology Careers?

Technology is an important example of why you should not assume every professional occupation requires a license.

Many common technology careers—such as software development, web development, cybersecurity, data analysis, product management, and many IT positions—do not generally require a state occupational license simply to work in the field.

Instead, employers may evaluate:

However, there can be exceptions when technology work intersects with a regulated profession or specific legally regulated activity.

For example, an engineer working in a role involving the practice of professional engineering may face different requirements from a software developer working on commercial software.

The job duties—not simply the word “technology” in the job description—should determine what you investigate.

Do You Need a License If You Already Have a Degree?

Not necessarily.

A degree and a professional license serve different purposes.

A degree demonstrates that you completed an educational program. A professional license can provide legal authorization to perform regulated work.

Some careers require both.

For example, an occupation may require a specific degree before you can qualify for the licensing process. Other careers may have no licensing requirement at all.

This is why earning another degree does not automatically solve a licensing requirement—and having a degree does not automatically mean you are authorized to practice a regulated occupation.

Do You Need a License If the Job Posting Does Not Mention One?

Not necessarily.

Job postings are not always complete descriptions of every legal requirement associated with an occupation.

If you are entering a regulated profession, you should independently verify the licensing requirement even if the employer's job description does not clearly explain it.

Conversely, a job posting may say “license preferred” when the license is not legally required for every person performing the position.

Read the wording carefully:

What If You Are Moving to Another State?

Moving can create a licensing issue even when you already have substantial professional experience.

Before accepting a position in another state, investigate whether your existing license can be transferred, recognized, or endorsed.

Do this before assuming you can start working immediately.

Your research should answer:

CareerOneStop's License Finder provides state-specific licensing information and identifies the agencies responsible for licenses.

What Happens If You Work Without a Required License?

If an occupation legally requires a license, you should not assume that an employer can simply waive the requirement.

Because an occupational license can provide legal authority to practice, working without the required authorization may create regulatory, professional, contractual, or legal problems depending on the occupation and jurisdiction.

The consequences vary by profession and state, so this is an area where you should verify the requirements directly with the relevant licensing authority rather than relying on career advice websites.

If a job requires a license, treat it as a genuine eligibility requirement rather than another optional resume credential.

How to Tell Whether a License Is Actually Required

Use this five-part checklist before applying for a regulated position.

  1. Identify the exact occupation. Do not rely solely on the employer's job title.
  2. Identify the state. Licensing rules are jurisdiction-specific.
  3. Find the regulating agency. Use the state's official licensing authority or CareerOneStop's License Finder.
  4. Review the legal requirements. Check education, examination, experience, background, and renewal requirements.
  5. Verify before starting work. If the rules are unclear, contact the licensing agency directly.

CareerOneStop's License Finder covers nearly 900 occupation titles and allows users to search by occupation, license name, licensing agency, and state.

License Requirements Can Affect Your Career Strategy

Licensing should be considered early when planning a career—not after you have already spent significant time preparing for a job.

If you are choosing between two career paths, for example, one occupation may require years of education, supervised experience, and state licensing while another may allow you to enter the workforce more quickly.

That does not mean a licensed career is a bad choice. It means you should understand the investment before committing to it.

A career licensing assessment should consider:

BLS's Occupational Requirements Survey tracks credential requirements as part of the requirements associated with performing critical job functions. Its 2025 data found that 22.9% of civilian workers had jobs requiring a license or certification, although the proportion varies dramatically across occupational groups. Healthcare practitioners and technical workers, for example, had a much higher rate of license or certification requirements.

What If You Are Changing Careers?

If you are changing careers, licensing requirements can significantly affect your transition plan.

You may already have years of professional experience, but that experience does not necessarily substitute for a legally required credential.

Before making the transition, determine whether your previous education or experience can satisfy any part of the new licensing process.

Some states have alternative pathways, reciprocity arrangements, or experience-based requirements, while others have highly structured education and examination requirements.

This is also where professional career guidance can be useful. LiaHia provides career services that can help professionals evaluate career transitions, training needs, licensing and certification considerations, resume positioning, and job-search strategy.

If you already know the career you want but are unsure which credential is required, a licensing and certification assessment can help you determine what to research before investing in education or training.

If the licensing question is only one part of a larger career transition, career coaching can help you build a broader transition plan around your experience, target roles, skills, and qualifications.

Do Licenses Expire?

Many professional licenses must be renewed periodically.

Renewal requirements can include fees, continuing education, professional development, examinations, or other conditions depending on the occupation and state.

BLS notes that licenses, like certifications, can expire if they are not renewed.

This means getting licensed is not necessarily the end of the process. You may need to maintain the credential throughout your career.

Where Should You Check Your License Requirements?

Use authoritative sources whenever possible.

The best starting points are:

CareerOneStop specifically warns that its licensing database may not contain every license from every state because participation in the data collection process varies. Therefore, when the stakes are high, verify the requirement directly with the relevant state agency.

Final Takeaway

Whether you need a license depends on your occupation, your responsibilities, and where you will work.

Do not assume that every professional needs a license, and do not assume that having a degree or certification gives you legal authority to practice a regulated occupation.

If you are entering healthcare, education, law, real estate, skilled trades, transportation, personal care, or another regulated profession, investigate licensing requirements before investing in your career transition.

If you are pursuing a technology, business, marketing, administrative, or other less-regulated career, a state occupational license may not be necessary—but specific employers may still require certifications or other credentials.

The safest strategy is simple: identify the exact occupation, identify the state, find the licensing authority, and verify the requirements directly.

Frequently Asked Questions

How do I know if my career requires a license?

Start by identifying your exact occupation and the state where you will work. Then check your state's licensing agency or use CareerOneStop's License Finder. Licensing requirements vary by state, so do not assume that a license required in one state is required in another. CareerOneStop allows you to search by occupation and state to identify potential licensing requirements.

What jobs require a professional license?

Many healthcare, education, legal, personal-care, skilled-trade, transportation, real-estate, and other regulated occupations can require professional licenses. The exact requirements depend on the occupation and jurisdiction. Some jobs within these industries may not require a license, so the specific position and duties matter.

Is a professional certification the same as a license?

No. A license is generally issued by a government agency and provides legal authority to practice an occupation. A certification is generally issued by a nongovernmental organization and demonstrates knowledge or competency. Some professionals hold both.

Do I need a license if I have a college degree?

Not necessarily. A degree and a professional license serve different purposes. Some occupations require a specific degree as part of the licensing process, while other careers do not require occupational licensing at all. Having a degree does not automatically authorize you to perform regulated professional work.

Can I transfer my professional license to another state?

Sometimes. Whether a license can be transferred depends on the profession and the states involved. You may qualify for endorsement or reciprocity, but you could also need additional education, examinations, experience verification, or other requirements. Always check with the licensing authority in the new state before beginning work.

Can I work without a license if my employer does not require one?

If the occupation is legally regulated and requires a license, an employer's decision not to mention or enforce the requirement does not necessarily eliminate the legal requirement. Verify the rules with the appropriate licensing agency before performing regulated work.

Does LiaHia help with licensing requirements?

LiaHia provides career services that can help professionals evaluate licensing and certification considerations, career transitions, training needs, resume and LinkedIn positioning, and job-search strategy. The appropriate support depends on whether you need help understanding a credential requirement or developing a broader career plan.
