Check the number yourself.

Integrity and quality matter most to us. That is exactly why publishing is one-way. Type a certificate number and you will land on the same record every other stranger holding it sees — the measured values, the analyst notes, the withdrawals — with no login, no request form, and no second version of it reserved for the vendor.
