Fake Patient Generator for Testing
Generate synthetic patient records in one click — realistic names, dates of birth, member IDs, group numbers, never-issued SSNs, addresses, and fictional phone numbers for development, QA, training, and demos. Bulk up to 100 with JSON and CSV export. Free, no signup, nothing stored.
For testing only. These records are randomly generated and belong to no real person. Never use them on a real claim or any HIPAA-covered transaction.
Generated in your browser — nothing is sent to or stored on our servers.
Built to be realistic — and provably fake
Every field is chosen so records behave like real patient data in your forms and pipelines, while being mathematically impossible to confuse with real people:
- SSNs use the 900–999 area range the SSA has never issued — guaranteed unassigned
- Phone numbers use the 555-01xx range reserved for fiction
- Member IDs and group numbers follow common payer formats
- Names drawn from common US first/last name lists, matched to gender
- Uniqueness guaranteed within every batch

Realistic patient data, zero PHI risk
Development & QA
Populate dev and staging databases, test claim intake and 837 generation, and run clearinghouse onboarding without a single real patient record.
Pipeline testing
Feed realistic subscriber and patient demographics through extraction, validation, and adjudication pipelines so tests behave exactly like production.
Training & demos
Teach billing staff and demo products with realistic-looking patient records — keeping PHI out of classrooms, screenshots, and slide decks.
Building a full test claim? Generate the patient here, grab a rendering and billing NPI from the Fake NPI Generator, and validate any real NPIs with the NPI Validator.
