Can you use MD if not licensed?

No, you should not use MD if you are not licensed. The title MD means Doctor of Medicine.
It signals that you completed medical school. But using it professionally implies you are a practicing physician. Many states legally restrict the use of MD to licensed doctors.
Using it without a license can be considered fraud. You could face fines, legal action, or professional penalties. Even in emails or social media profiles, it misleads others. Patients and employers trust medical titles to be accurate.

Legal and professional consequences
Medical boards enforce strict rules about title use. Impersonating a licensed physician is a serious offense.
Some states classify it as a misdemeanor or felony. Employers may fire you if you falsely claim an MD license. You could lose future job opportunities in healthcare. Universities and research institutions may revoke your credentials. Using MD without a license damages public trust.
It also puts other professionals at risk of scrutiny. Never use MD on business cards, websites, or patient-facing materials. Do not sign clinical documents or prescribe medication. Even if you earned your degree, the title has legal meaning.

When MD is acceptable without a license
You may list MD after your name in academic or research roles. For example, an MD who works in data science or policy can use it. Always clarify your role: “MD, Research Analyst” or “MD, Non-Practicing.”
Avoid any phrasing that suggests you provide medical care. Say “I hold an MD but do not practice medicine.” This keeps your credentials honest and your actions ethical. The phrase use MD if not licensed is misleading and dangerous. The correct approach is to be transparent. Your degree is an achievement.
But your title must match your legal authority. Use MD only when you are authorized to practice.
That protects you, your career, and the people you serve. use MD if not licensed is never acceptable in professional settings. Honesty builds credibility. Misrepresentation destroys it. Always choose clarity over convenience
