# Ownership API: Search by phone
URL: /docs/changelogs/2026-09-09
LLM index: /llms.txt
Description: Look up people and contact details from a US phone number with GET or POST /v1/ownership/phone.

## Added

- [Ownership by phone](/docs/products/ownership) — `GET` and `POST /v1/ownership/phone`. Start from a US 10-digit number (comma-separated list or a `phones` array, max 100) and get back the same identity, contact, demographics, and vehicle-history fields as Person. Same `ownership` entitlement and per-match billing as the other lookup types.
