What Is a Board-Certified Doctor?
May 8, 2026
When researching a physician, you'll often encounter the phrase "board-certified." This is a meaningful credential — but it's important to understand exactly what it signifies and how it's different from simply being licensed to practice medicine.
What Board Certification Means
Board certification indicates that a physician has voluntarily demonstrated expertise in a specific specialty by passing a rigorous examination administered by a specialty board — such as the American Board of Internal Medicine, the American Board of Pediatrics, or the American Board of Surgery. Certification requires completing an accredited residency (and often fellowship) and passing both written and, in many specialties, oral examinations.
Board Certification vs. Licensure
Licensure (the state medical license) is the legal requirement to practice medicine. Board certification is voluntary and above and beyond licensure. A physician can be licensed without being board-certified. Many patients prefer board-certified physicians because it provides an additional, specialty-specific quality signal.
Does NPPES Show Board Certification?
No — the NPPES registry does not include board certification status. NPPES records the provider's taxonomy code (specialty) but does not track whether they've passed board exams. For board certification verification, use the ABMS website (for MD physicians) or the AOA website (for DO physicians). Use DoctorDataHub's provider search to identify and locate providers, then verify board certification separately.
