The list

ISO 17025 accredited laboratories: the full list

This is our full list of ISO/IEC 17025 accredited laboratories: 6,375 of them, in 58 countries. Every one comes from the public register of a national accreditation body, the official organisation that inspects laboratories and publishes which tests each one is qualified to run. Open any country to see the laboratories themselves.

Every country in the register

The counts below add up to 6,375, which is the whole list. Nothing is held back.

Where this list comes from

Every laboratory above was read from the public register of one of these national accreditation bodies. Each body is the organisation its own country recognises to inspect laboratories and publish what they are accredited to test.

Adding this column gives 6,379, which is 4 more than the 6,375 laboratories on this page. 4 laboratories hold accreditation from two of these bodies, and each body counts it in its own register, so we do not quietly drop one of the two.

How to check a laboratory yourself

Being on this list means a national accreditation body published a certificate for that laboratory. It does not mean the laboratory is accredited for the particular test you need. Accreditation is granted test by test, and the list of what a laboratory may do is called its scope.

Check a certificate to confirm an accreditation number is real and current. Check what a lab can test to see whether a specific standard sits inside that laboratory's accredited scope before you send the work.

If you need a specific test

This page enumerates the register. If you would rather narrow it, browse by country, material and method, search by keyword against the scope text itself, or describe the problem in a sentence. The front page is the place to start if you do not know which of those you want yet.
