What is the name of Banksy’s art authentication organisation?

Banksy’s art authentication organisation is called Pest Control.

Pest Control issues certificates of authenticity for works attributed to Banksy. Because the artist is anonymous and Banksy’s images are frequently copied, forged or reproduced without permission, an authentication system is important in the art market.

The organisation is also known for its deliberately unconventional name and communications. Its role is separate from simply deciding whether an image resembles Banksy’s style: provenance, documentation and the physical work can all matter when an artwork is assessed.

Pest Control is sometimes mistaken for a gallery, studio or commercial publisher. It functions primarily as Banksy’s official authentication body, while auctions and galleries handle the buying and selling of works.
