  • 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.
  • Review the Online Directory
    The Official ABMS Directory of Board Certified Medical Specialists,  published by Elsevier under license from ABMS, is an electronic database that lists information on physicians who have met the certification requirements of their respective medical specialty boards. It includes data from ABMS combined with information collected from the physicians to create biographies that include type of specialty, subspecialty (if applicable), and original certification year. This publication is updated quarterly and is not recognized as primary source verification (PSV) for credentialing purposes, though it can still be used as a reference resource. Data for PSV and credentialing is available through our ABMS Certification Verification Products and Display Agents. Access to is available in many medical and public libraries.
