Physician Verification Inquiries
There are three easy, direct ways to verify physician certification through ABMS:

• Check Online
  As part of its public service mission, access to the ABMS Medical Specialists Online certification verification service is available to the public free of charge. This self-serve resource allows you to conduct searches by a physician's name or area of certification and a state name. Start your search now.
• Make a Phone Call
  Call the toll-free ABMS Certification Verification Service at 1-866-ASK-ABMS (275-2267.) Please note: Agents can only provide certification verification. They cannot provide you with detailed biographical or residency training information, help you locate a physician or register complaints against a physician.
• Look in the Book
  The Official ABMS Directory of Board Certified Medical Specialists,  published by Elsevier under license from ABMS, lists information on physicians who have met the certification requirements of their respective medical specialty boards. Certification information from ABMS is combined with information collected from the physicians to create biographies that include type of specialty, subspecialty (if applicable), and years of certification, sub-certification, re-certification and time-limited certification as appropriate. This publication is not recognized as primary source verification (PSV) for credentialing purposes, though it can still be used as a reference resource. Data for this purpose is available through our ABMS Certification Verification Products. The directory can be found in many medical and public libraries.
