Accession Number
When a company files a document with the SEC, the system assigns it an accession number. This number acts like a tracking code for that specific filing.
Each accession number is unique and never reused. It allows filings to be precisely identified, even when multiple documents are filed on the same day.
Accession numbers are used across EDGAR links, data feeds, and SEC references. They help ensure users are looking at the exact document intended.
Why It Matters
Accession numbers make SEC filings easy to locate, verify, and reference. They reduce confusion and support accurate data retrieval.
How is an accession number used to find SEC filings?
Accession numbers are embedded in EDGAR URLs and database records. Entering the number allows direct access to a specific filing. This avoids searching by company name or date. It ensures precise retrieval.
Why are accession numbers important for data accuracy?
Accession numbers prevent mix-ups between similar filings. Even if two filings share the same form type and date, their accession numbers differ. Data systems rely on them as primary keys. This supports clean and reliable datasets.
Do accession numbers change after a filing is submitted?
No, once assigned, an accession number stays permanent. Amendments receive their own accession numbers. This creates a clear record of filing history. It also helps track changes over time.
Real-World Example
An analyst saves the accession number of a 10-K filing to quickly return to the exact document later. This avoids confusion if newer filings are released.
