Provider Signals™Reach new physicians the week they start — not from a stale list.
Every physician mailing list goes stale. Provider Signals is continuous provider intelligence — newly enumerated physicians, NPs, and practices from CMS NPPES each week, with verified postal addresses, specialty, and NPI. A compliant, current physician mailing list of new providers, built for territory growth.
Why a new-provider mailing list beats a generic one
A list of all 1.2M active physicians is a commodity — available from the AMA, ZoomInfo, and dozens of list brokers. A list of physicians who joined NPPES in the last 90 days is not. New providers haven't been blanketed by competitors yet, are actively making setup decisions (equipment, software, insurance, staffing), and have the highest lifetime value for any vendor who reaches them first.
What's included in the physician mailing list
Every record is sourced from the public NPPES dataset. Fields are as submitted by the provider to CMS — we normalize and add freshness tracking, but we don't infer or synthesize data we don't have.
| Field | Notes |
|---|---|
| Full name | Individual provider (first/middle/last/credential) or organization name |
| Practice mailing address | Street, city, state, ZIP+4 — the postal address on file with CMS |
| Practice phone | Registered practice phone (where self-reported) |
| NPI number | 10-digit National Provider Identifier — unique, permanent identifier |
| Specialty / taxonomy | Primary taxonomy code mapped to readable specialty (e.g., Internal Medicine, NP — Family) |
| Entity type | Individual (Type 1) or Organization (Type 2 — new practices) |
| Enumeration date | When the provider was added to NPPES — use to filter to "new" providers only |
| State of licensure | Self-reported state license number(s) where provided |
Postal addresses, not email. This is a doctor mailing list in the traditional sense — practice postal addresses from the federal provider registry. We do not provide personal or work email addresses. If you need email enrichment, that requires a separate contact-enrichment source on top of NPPES. See our healthcare provider database overview for full context on what NPPES covers.
Why NPPES new-provider data beats a generic doctor mailing list
Most commercial physician mailing lists are static — the same 1.2M names every list broker sells. Provider Signals is different because we focus exclusively on what's new:
- Weekly new-provider alerts — we diff each CMS NPPES release to surface physicians and practices enumerated in the last 7 days
- First-mover advantage — reach newly licensed physicians before pharma reps, device vendors, and credentialing firms flood their mailbox
- Federal source, no licensing ambiguity — NPPES practice addresses are public domain; no AMA Masterfile licensing fees or scraping legal risk
- New practice signal (Type 2 NPI) — a new organization NPI means a new clinic just opened; those practices are buying equipment, software, and services right now
- OIG-clean list — combine with OIG exclusion screening to automatically exclude sanctioned providers from your campaign
Filter to the exact physician audience you need
A physician mailing list is only useful if it's targeted. Provider Signals lets you slice by:
- Specialty — any taxonomy group (cardiologists, orthopedic surgeons, family medicine, NPs, PAs, and 300+ more)
- State, ZIP code, or county
- Entity type — individual physicians vs. new practice organizations
- Enumeration date — filter to providers added in the last 30, 60, or 90 days for a "new provider" list
- Exclude OIG-excluded providers — combine with OIG exclusion screening to remove sanctioned providers before your campaign
Frequently asked questions
Are these email addresses or postal addresses?
Postal addresses only — the practice mailing address as registered in NPPES. We do not provide personal or work email addresses. For email data you would need a separate contact-enrichment layer on top of NPPES.
Is a physician mailing list from NPPES HIPAA compliant?
NPPES data is public — CMS publishes the full registry for download. Provider practice addresses are not protected health information (PHI) under HIPAA; they are professional contact details for licensed providers. They are routinely used for B2B direct mail by pharma, device, and CME companies without HIPAA concerns. CAN-SPAM applies to email, not postal mail, so there are no opt-in requirements for physical direct mail to businesses.
How often is the physician mailing list updated?
CMS publishes a fresh NPPES file weekly. Provider Signals ingests each update, so new providers and address changes are reflected within days. If a practice moves or a new physician joins NPPES, your next export will include the corrected address.
Can I filter the physician mailing list by specialty?
Yes. Every provider in NPPES carries a taxonomy code that maps to a specialty. You can filter to any specialty — cardiologists, nurse practitioners, family medicine, dermatologists, and so on — and combine with state, ZIP radius, or county.
Can I target only newly licensed physicians?
Yes — this is one of the most valuable filters. Set an enumeration date range (e.g., added to NPPES in the last 90 days) to build a list of recently licensed physicians or newly opened practices. These are the highest-value targets for pharma reps, device reps, and credentialing services. See the new medical practices hub for specialty-and-state breakdowns.
What's the difference between a Type 1 and Type 2 NPI?
Type 1 NPIs are assigned to individual providers (physicians, NPs, PAs). Type 2 NPIs are assigned to organizations — group practices, hospitals, clinics. A new Type 2 NPI is one of the strongest signals that a new practice has opened. You can filter to either or both depending on whether you want to reach individual physicians or practice decision-makers.
