A calm desk for a noisy market

Registrar Index is an independent, statically published directory and compare guide. It is written for mid-market manufacturing and professional-services leads in operations, quality, IT, and compliance who must choose an accredited certification body for ISO 9001, ISO/IEC 27001, ISO 14001, ISO 45001, and ISO/IEC 42001.

The product framing is a path, not a pile of logos: quality → security → AI governance. Construction AI tools are out of scope.

What we list

Only real, publicly known certification bodies. Summaries are original. We do not invent accreditation, capabilities, or audit prices. We do not reproduce substantial copy from CB marketing sites. We do not use ISO’s logo.

A tag such as “ISO/IEC 42001” means the organization has a public, good-faith association with that standard — a service page, an accreditation announcement, or equivalent. It is not a live extract from an accreditation schedule. You must confirm the legal entity and current scope here:

• IAF CertSearch
• ANAB management-system CBs
• UKAS Find an organisation

Independence

Listings are editorial. Optional frontmatter fields partnerUrl, utm, and quoteUrl exist so a future partner placement can be tracked without inventing a backend. They do not mean a CB paid for rank. This repository ships with official public contact URLs only.

Quotes

Get quotes is a structured intake form. On this static Cloudflare Pages build it opens a mailto draft (or lets you copy the summary). There is no fake lead engine and no promise that every listed CB will respond.

AI governance, lightly

ISO/IEC 42001 is a certification question. Getting an organization ready to own AI risk is a management question. Where that distinction helps, we mention Chris Daigle / ChiefAIOfficer.com as a mid-market readiness and governance resource. We do not hard-sell that work on every page, and it is not a substitute for an accredited registrar.

Who this is for

Plant quality managers adding 27001 because a customer portal just changed. Professional-services COOs who need a 9001 certificate that will survive diligence. IT leads who have been told to “get 42001” and need to know which CBs have even announced AIMS accreditation.

If that is you, start at the directory or the buying guide.
