AMA Physicians List – Frequently Asked Questions

What is the AMA Physician Masterfile? The AMA Physician Masterfile is the American Medical Association's database of U.S. physicians, covering 1.5 million records including both AMA members and non-members. It includes active practicing physicians, residents in training, MDs, DOs, and international medical graduates, making it the most complete single source of physician information available to healthcare marketers.

How many physicians are in the AMA Physicians List? The list contains 1.5 million total physician records, of which more than 1.2 million are active physicians. Because it covers members and non-members alike, it represents essentially the entire U.S. physician population rather than a subset.

How often is the AMA Physician List updated? The Masterfile is updated weekly. Approximately 135 million transactions from more than 2,300 data sources are applied to the file each year, which is why office-based and hospital staff physician records maintain 98% mail deliverability.

How do I get access to AMA physician data? The AMA does not sell its PPD directly to marketers. Access is available through authorized AMA Database Licensees such as MMS, which license the data and provide it with selection, counts, and campaign deployment services for direct mail, email, and digital marketing.

What targeting selections are available on the AMA list? More than 20 selections are available, including primary and secondary specialty, type of practice, ABMS board certification and sub-certification, geography (state, county, ZIP, metro area, CBSA), age, gender, medical school, residency program and completion year, and language spoken. Prescribing (Rx)** data by market, therapeutic class, and product are also available on qualifying records.

What is the difference between the AMA Physicians List and a compiled physician list? Compiled lists are assembled from public records, websites, and third-party sources with no single verification authority, so accuracy varies widely. The AMA PPD is a professionally maintained file verified against sources such as medical schools, residency programs, and licensing boards, updated weekly and matched to ME and NPI numbers, which is why it remains the industry standard for physician marketing data.

Does the AMA list include physician email addresses? Yes. Email coverage reaches up to 95% of records via MMS's Med-E-Mail Network, and MMS can deploy campaigns through email broadcasts and the NOWW Platform services.

Can I target medical residents with the AMA list? Yes. Resident data is collected by the AMA from the GME census and reporting residency programs. The most effective window for direct mail campaigns to residents is November 1 through May 31.
