What is IAF accreditation?

IAF accreditation means your registrar is itself audited by a recognized accreditation body such as ANAB. It is what makes your certificate acceptable to an OEM's supplier quality team.

What it is

There is a chain of oversight above your certificate. You are audited by a registrar. The registrar is audited by a national accreditation body. Those accreditation bodies recognize each other through the International Accreditation Forum, which is what allows a certificate issued in Utah to mean something to a customer in Germany.

In the United States the accreditation body you will see most often is ANAB, the ANSI National Accreditation Board. Elsewhere it is UKAS, DAkkS, JAS-ANZ, and their national equivalents.

Accreditation is what obliges your registrar to follow ISO/IEC 17021-1: to stay independent of consulting, to size audits by the published day tables, and to write defensible findings. A certificate from an unaccredited body carries none of those guarantees and costs less for exactly that reason.

When you will hear it

When a customer's supplier quality team reviews your certificate. They check the accreditation mark, and an unrecognized one is a rejected certificate.

When you compare quotes and one is notably cheaper and faster than the rest. That is the moment to look at who accredits the body, not just what it charges.

In defense and aerospace flowdown, where the requirement is often written as third-party registration by an accredited body rather than simply certification.

What the auditor expects to see

This one runs in the other direction: you check them. Before you sign, verify the body's accreditation on the accreditation body's own directory rather than on the registrar's website. ANAB publishes a searchable directory, as do its international counterparts.

Check the scope of the accreditation too. A body may be accredited for ISO 9001 but not for AS9100 or ISO 13485. The certificate you need has to be inside the scope they hold.

Common mistakes

Taking the logo at face value. Accreditation marks are reproduced freely on marketing material. The directory is the check.

Assuming all accreditation is equal in your customer's eyes. Some primes maintain their own list of acceptable bodies that is narrower than the IAF membership. If you are in an aerospace or defense supply chain, ask your customer before you choose.

Discovering the problem at the customer audit. Recertifying with an accredited body after a rejected certificate means paying for the whole initial audit again.

FAQ

How do we check if a registrar is accredited?

Search the accreditation body's public directory by the registrar's name. In the United States that is the ANAB directory. Do not rely on the registrar's own claim.

Is an unaccredited certificate worthless?

Not literally, but it is worth only what the customer accepts, and supplier quality teams at the primes routinely reject them. If certification is being driven by a customer requirement, unaccredited is a false economy.

Does accreditation cost us anything?

Not directly. It is a cost to the registrar, reflected in their fees. An unaccredited body is cheaper partly because it carries none of that overhead.

Can accreditation be withdrawn?

Yes. Bodies are audited on a cycle and can be suspended. If your registrar loses accreditation you will need to transfer, which is one more reason to choose an established body over the cheapest quote.
