Verify a Certificate
Confirm that a certificate number was issued by Certified Microplastic-Free™ and check its current status.
Certificate lookup
Certificate numbers appear on the certificate document and alongside the seal in certified product listings.
About verification
Every certified product family receives a unique certificate number when certification is granted. If a product displays the Certified Microplastic-Free™ seal but its certificate number cannot be verified here, or no number is provided, please report it to info@microfree.org.
Certification status can change. A certificate shown as expired or revoked means the product is no longer authorized to display the seal.
