Advisory organizations
ISO and AAIS state filings
Insurance Services Office (ISO) and the American Association of Insurance Services (AAIS) are advisory organizations, not insurers. They write standard policy forms, manual rules and advisory loss costs and file them with state insurance departments. This page counts and lists the filings ISO and AAIS made themselves. These are the state filings, not ISO circulars, which go to participating companies and are not hosted on this site.

A filing here is one SERFF submission to one state, so a single ISO or AAIS filing sent to 30 states counts 30 times. The filing reference is the organization's own number for the filing (for example AAIS-2025-46LC), shared by every state copy. Withdrawn and rejected filings are excluded. Florida files through its own I-File system rather than SERFF, so it shows none.
Filings by month
State filings submitted each month from Dec 2024 to Nov 2026. The last month is partial.
