How to Authenticate a Banksy: Pest Control, Provenance and Collector Confidence
Understanding how to authenticate a Banksy helps collectors buy with greater confidence. The only organisation authorised to authenticate a Banksy print or artwork is Pest Control Office, established by Banksy in 2008. Before acquiring any Banksy, collectors should ensure the work is accompanied by a valid Pest Control Certificate of Authenticity, alongside provenance. Together, these elements help establish authenticity, legitimacy, and long-term collectability.

Who Authenticates Banksy Artworks?
Pest Control Office is the only organisation authorised to authenticate genuine Banksy artworks. Established by Banksy in 2008, Pest Control was created to provide an official authentication framework as international interest in the artist’s work expanded. Its certificates are recognised by collectors, galleries, auction houses, insurers, and institutions worldwide.
No gallery, dealer, advisor, auction specialist, or collector can independently authenticate a Banksy. While experts may provide guidance on provenance, condition, and market context, recognised authentication is issued exclusively by Pest Control Office.
What Is a Pest Control Certificate of Authenticity?
A Pest Control Certificate of Authenticity COA is the official document issued by Banksy’s authentication body confirming that a work is recognised as genuine. It is one of the most important documents a Banksy collector can hold, and its presence or absence can significantly affect a work’s insurability, exhibitability, collectability, and resale value.
Each certificate is individually issued for a specific artwork and contains identifying information relating to the work, including its title, medium, edition details where applicable, and a unique certificate number. One of the most recognisable features of many Pest Control certificates is the inclusion of a section of a Banksy-designed Di-Faced Tenners note, with each certificate carrying a unique half-note that corresponds to the authenticated artwork. Certificates also incorporate additional security features designed to help prevent forgery and protect the integrity of the authentication process.
For collectors, these elements provide an additional layer of confidence and traceability, reinforcing the certificate’s role as the recognised standard of authentication within the Banksy market.
For many collectors, the certificate becomes an integral part of the artwork itself. It accompanies the work throughout its life, helping future owners, galleries, auction houses, insurers, and institutions verify authenticity and provenance with confidence.
While the artwork remains the primary object of interest, the Pest Control Certificate serves as the recognised link between that work and Banksy’s official body of authentication. In today’s market, it is the gold standard of verification for Banksy editions and original artworks. The two come together.

Why Does Banksy Authentication Matter?
Authentication establishes confidence. It confirms that an artwork has been recognised within Banksy’s body of work and provides reassurance for collectors, future owners, insurers, galleries, institutions, and auction houses.
At GraffitiStreet, we would never recommend acquiring or selling a Banksy without recognised a Pest Control certificate of authentication. In our experience, authentication and the artwork itself go hand in hand. While an artwork may have a compelling history or visual appeal, recognised authentication remains one of the foundations upon which collector confidence is built.
For works that do not have a Pest Control Certificate of Authenticity, we always advise collectors to explore the possibility of obtaining one through Pest Control Office before proceeding. The process can be lengthy and, in some cases, Pest Control may require additional documentation or physical inspection of the artwork before reaching a decision. While retrospective authentication is not always guaranteed, it remains an important step in establishing confidence and long-term collectability.
Authentication rarely exists in isolation, however. An artwork also carries a history. Where has it been? Who has owned it? How did it enter the market? What documentation accompanies it? These questions help build a fuller understanding of the work and form part of its wider story. This is where provenance becomes equally important.
What Is Provenance and Why Does It Matter?
Provenance is the documented history of an artwork’s ownership. For collectors, it provides a chain of custody and a clearer understanding of how a work has moved through private collections, galleries, exhibitions, major auction houses, and the wider art market.
A Banksy with recognised Pest Control authentication and strong provenance will typically inspire greater collector confidence. Provenance helps establish context, transparency, and trust while offering valuable insight into an artwork’s journey over time.
Supporting documentation may include gallery invoices, acquisition records, auction results, exhibition histories, collection details, and correspondence relating to the work. Together, these records help create a more complete picture of an artwork’s life beyond the moment it was first acquired.
Beyond ownership records, provenance forms part of an artwork’s cultural narrative. It tells the story of where a work has been, how it has been cared for, and the role it has played within collections and the broader history of contemporary art.

Can a Banksy Be Sold Without Authentication?
The absence of recognised authentication does not automatically indicate that a work is not genuine. Documentation may have been lost over time, ownership histories may be incomplete, or a work may never have been submitted to Pest Control for authentication. Nevertheless, recognised Pest Control authentication remains the strongest foundation for collector confidence, and most established galleries, auction houses, institutions, and private collectors place significant weight on it when evaluating any Banksy artwork.
At GraffitiStreet, we maintain a clear position on this matter. We would not offer a Banksy for sale without a recognised Pest Control Certificate of Authenticity. In our experience, authentication and collectability go hand in hand. The certificate provides confidence not only for the current owner but also for future collectors, insurers, institutions, and the wider market.
For works that do not currently have a Pest Control Certificate, we always advise pursuing authentication before considering a sale or acquisition. While the process can sometimes be lengthy and may require additional documentation or inspection, it remains one of the most important steps in establishing confidence, transparency, and long-term collectability within the Banksy market.
What Should I Look For Before Buying a Banksy?
Experienced collectors rarely focus on a single factor in isolation. The strongest acquisitions are typically informed by a combination of authentication, provenance, condition, rarity and cultural significance.
A valid Pest Control Certificate of Authenticity helps establish confidence that the work is recognised within Banksy’s body of work. Provenance provides a documented ownership history, offering insight into how the artwork has moved through collections, galleries, exhibitions, and the wider market. Condition remains equally important, particularly for works on paper, while rarity can influence desirability through edition size, colour variation, or the distinction between a print and a unique work.
Collectors also consider where a work sits within Banksy’s wider practice. Certain images have become defining symbols of contemporary culture, while others represent important moments within the artist’s evolving career.
The most successful acquisitions are rarely driven by urgency. They are built through patience, research, and an understanding of the factors that contribute to an artwork’s long-term significance.

The Banksy Market
Banksy’s work challenges authority, questions systems of value, and asks audiences to look beyond appearances. It is fitting, then, that collecting Banksy also requires careful observation, research, and due diligence.
Authentication, provenance, and documentation are not obstacles between collectors and artworks. They are the framework that preserves confidence in the market and respect for the work itself. For many collectors, that confidence becomes one of the most valuable things they acquire.
During more than 13 years working with Banksy collectors and the wider contemporary art market, we have seen first-hand how trust underpins every successful acquisition. Whether purchasing a signed print, an unsigned edition, or a rare original work, collectors who take the time to understand authentication, ownership history, condition, and provenance are often the ones who build the strongest and most rewarding collections. It is about understanding its story, its journey, and its place within one of the most influential artistic practices of our time.
Over more than a decade, GraffitiStreet has cultivated a global network of Banksy collectors and contemporary art buyers, many of whom return to us for guidance, insight, and access to significant works. We have found that the most rewarding acquisitions are built on transparency, research, and trust rather than urgency alone.

Frequently Asked Questions About Banksy Authentication
Pest Control Office is the only organisation authorised to authenticate genuine Banksy artworks. Established by Banksy in 2008, it remains the recognised authority relied upon by collectors, galleries, auction houses, insurers, and institutions worldwide.
A Pest Control Certificate of Authenticity COA is the official document issued by Banksy’s authentication body confirming that an artwork has been recognised as genuine. For many collectors, it is one of the most important documents associated with a Banksy and forms a key part of the work’s provenance. Every Banksy needs a Pest Control Certificate of Authenticity.
Provenance documents an artwork’s ownership history and helps establish confidence, transparency, and context. It provides insight into how a work has moved through collections, galleries, exhibitions, and the wider market throughout its lifetime.
It is very risky. Most established collectors, galleries, institutions, and auction houses approach unauthenticated works with significant caution. At GraffitiStreet, we would not offer a Banksy for sale without a recognised Pest Control Certificate of Authenticity, and one that is in hand and viewed by our expert.
Collectors should consider authentication, provenance, condition, rarity, and the significance of the image itself. The strongest acquisitions are usually supported by research, documentation, and a clear understanding of the artwork’s place within Banksy’s wider practice.
Pest Control Certificates can be verified through Pest Control Office and contain a number of identifying features, including a unique certificate number and a corresponding section of a Banksy-designed Di-Faced Tenners note.
Girl With Balloon is widely regarded as Banksy’s most recognisable and influential print edition. Its cultural impact extends far beyond the art world and it remains one of the defining images of contemporary art.
Signed editions are generally rarer and often command a premium. However, experienced collectors also consider image significance, provenance, condition, rarity, and cultural relevance rather than focusing on signature status alone.
An Artist’s Proof, often abbreviated to AP, is a print produced outside the main edition. These works are typically released in smaller numbers and may occasionally feature alternative colourways, making them particularly appealing to some collectors.
Pictures on Walls (POW) was the influential East London publisher responsible for releasing many of Banksy’s most important print editions. The organisation played a significant role in introducing Banksy’s work to a wider collecting audience.
Banksy’s most recent official print releases were the Thrower triptych and the Banksquiat screen prints, both issued through Gross Domestic Product in 2019.
A Banksy print is an editioned artwork produced in multiple examples, whereas an original artwork is unique. Both form important parts of Banksy’s practice, although they differ significantly in rarity, availability, and market context.
Many Banksy prints have performed strongly over time, but experienced collectors rarely focus on investment potential alone. Artistic significance, provenance, condition, rarity, and long-term cultural relevance often prove equally important considerations.
Banksy prints should be stored/ professionally framed using conservation-grade materials, protected from direct sunlight, and kept in stable environmental conditions. Proper care helps preserve both the artwork and its long-term condition.
Banksy’s prints combine instantly recognisable imagery, social and political commentary, cultural relevance, and limited availability. Together, these qualities have helped establish them as some of the most sought-after contemporary print editions in the world.
Yes. Pest Control reviews each submission independently and may decline to issue authentication if a work cannot be sufficiently verified. Authentication decisions remain entirely at the discretion of Pest Control Office.
All authenticated Banksy prints are accompanied by Pest Control Certificates of Authenticity COA.
Banksy’s unique combination of cultural relevance, political commentary, visual accessibility, anonymity, and historical significance has helped make his work one of the most closely followed sectors of the contemporary art market.
Unlike Banksy prints and original artworks, collectables, merchandise, books, exhibition items, and promotional objects are not accompanied by a Pest Control Certificate of Authenticity. Collectors should instead look for original purchase documentation, receipts, packaging, and clear provenance wherever possible.
Sculptures from Banksy’s Walled Off Hotel, include their own certificates, so collectors should always seek original receipts, secondary documentation from the hotel, and buy through reputable sources only.
Reputable sources typically include established galleries, recognised auction houses, specialist dealers, and trusted platforms with a proven track record in the contemporary art market. Collectors should always seek clear provenance, original documentation, and transparency regarding an item’s history before making a purchase.
