Federal Aviation Administration

FAA NOTAM Management Service (NMS) API

The distribution interface of the FAA's new NOTAM Management Service, the vendor-provided replacement for the legacy United States NOTAM System (USNS) and Federal NOTAM System (FNS). Discovered and verified live 2026-07-28 at nms.aim.faa.gov, an FAA-operated portal publishing system metrics, a transition FAQ and an API access request path. Access is not self-serve — the portal states verbatim "Please contact us at notams@faa.gov to request access to the new NMS-API." No OpenAPI, schema or endpoint documentation is published to unauthenticated visitors, so none was harvested. The portal's own metrics report 261 onboarded API users and roughly 338,000 API calls per day.
