Framework and location

372 pages that combine a framework with a location of three or more Verified firms. Examples:

How firms are listed

Verified firms are independently checked by Agent Index. Every fact must be confirmable on an official registry or the firm’s own website, with the source linked and the date checked.

This firm appears on the official registry, not independently verified by Agent Index. Firms with a regulatory or board-action flag or an unclear status on a cited registry are left out. Public-sector bodies that offer hireable audit or certification services are labelled “Government body” and can be excluded from the listing filter.

Listings are facts only, with no rankings or scores. Agent Index is 100% free to use through Q1 2027: you cannot buy inclusion, rankings or editorial notes. Optional labelled sponsorships, if they open in Q2 2027, will always be labelled “Sponsored” and kept separate from listings. Paying never gets a firm listed and never changes who is listed or in what order.
