What changed on SOS Filings

2026-10-13 secretary of state business search pass

SOS Filings published the secretary of state business search guides on sosfilings.us. Jurisdiction pages name the office on file and say what that search does not prove.

The SOS ID is whatever identifier that system prints: a numeric charter number, a number with a letter, or a document number. Copy it from the detail page after a secretary of state business lookup by name. Do not invent a format from another state.

SOS Filings is not a secretary of state and does not accept formations, annual reports, or certified copies.
