Accession number
The unique identifier of one submission to EDGAR, in the form 0001234567-25-000123.
Updated 2026-07-26
Every accepted submission gets an accession number. It identifies the envelope — the whole submission — rather than any single document inside it, and it never repeats. Two filings that look identical in a listing are different filings if their accession numbers differ.
The number encodes the filer agent, the year of submission and a sequence within that year. That structure is convenient but should not be read as meaning: the year in the accession number is the year of submission, not the year of the events being reported.
We store the accession number with every ingested document because it is the only key that makes a claim checkable. Given one, anyone can open the original in EDGAR and compare it with what we show.
