NOTAM Archive
Historical NOTAMs, two ways in.
NOTAMs updated in the last 6 months stay publicly browsable on notamify.com. Everything older moves to the archive: expired, cancelled, and replaced notices, kept with their original text and structured interpretation. You can query it, or you can take it with you.
Access
Two ways into the archive
Same records, different delivery. The API answers precise questions on demand. An export hands your team the corpus.
Archive API
A snapshot endpoint on the Notamify API. Give it a date and a set of ICAO locations, and it answers with the record set as paginated JSON.
Snapshot query
GET https://api.notamify.com/api/v2/notams/archive
?location=EGLL&valid_at=2023-11-04Every NOTAM in force at EGLL on 4 November 2023, including notices that have since expired or been cancelled.
- Endpoint
GET /v2/notams/archive- Pricing
- 1 credit per page
- Included
- Original text + interpretation
Data export
For work that needs the corpus rather than a query. We prepare bulk historical NOTAMs for the locations and period you name, and deliver them under a commercial licence. Exports reach up to five years back.*
Before anything is agreed, we check the archive against your scope and tell you exactly what we hold. Depth is not uniform across regions, and we would rather say so upfront.
- Depth
- Up to 5 years of history *
- Scope
- Your ICAO locations and period
- Licence
- Commercial, agreed per engagement
A useful rule of thumb: if the question sounds like “what was in force at EGLL on 4 November 2023”, the API answers it in one call. If it sounds like “everything for these forty airports over the last four years”, that’s an export.
* Export coverage is limited and subject to availability. Depth varies by location and source. Send us the scope and we confirm what we hold before any commitment.
Use cases
Where archive data ends up
A NOTAM stops being visible long before it stops being useful. Most archive requests are one of four questions.
Occurrence investigation
Rebuild the notice picture around an event: what was published, what was active, and what applied to the aircraft and operation in question.
Claims and disputes
Confirm which restrictions were in force on the date of a claim. The original text is preserved alongside the interpretation, so nothing rests on a paraphrase.
Audit and compliance
Show, months or years later, what information was available when a briefing was assembled or an operational decision made.
Research and models
Long-horizon NOTAM datasets for disruption analysis, network studies, and training data, drawn from millions of processed notices.
FAQ
Common questions
For anything specific, like exact locations, depth, or licence terms, the fastest route is to send the scope and let us check it against the archive.
- How far back does the archive go?
- The Archive API serves Notamify's full retained history. Bulk exports reach up to five years back, depending on the locations involved. Coverage is limited and subject to availability, so we confirm what we hold for your scope before anything is signed.
- Why do older NOTAM pages on notamify.com show a locked state?
- Public lookup covers NOTAMs updated in the last 6 months. Older records move to the archive, where they remain available through the Archive API and licensed exports.
- What does an archived record contain?
- The NOTAM as originally published, plus Notamify's structured interpretation: affected elements such as runways, taxiways, airspace, services, and navigation aids, each with its operational effect.
- How are exports licensed and priced?
- Exports are supplied under a commercial licence, priced by the scope of locations and period, and agreed per engagement. Archive API usage is billed in standard API credits at 1 credit per page.
- Can you check coverage before we commit?
- Yes. Send the ICAO locations and date range through the export request or the contact page, and we verify availability for your scope first. Coverage varies by region and source.
Next step
Tell us the date and the airports.
If it happened in the last five years, there is a good chance the notice picture can be reassembled. Query the archive yourself, or have us prepare it as a licensed dataset.
