A certificate of authenticity (COA) is a signed document an artist provides with an artwork to confirm it is genuine. It is the art-world equivalent of a hallmark: the collector keeps it with the work, galleries store it in their archive, and resale platforms reference it when the piece changes hands. For original paintings, sculptures, photographs, and limited-edition prints, a COA is now expected.
A good certificate includes the artist's name, the artwork's title, year, medium, dimensions, edition details, a unique reference number, the date of issue, and the artist's signature. Many artists also include a QR code linking to a verification page on their website — that's an option in this generator.
This tool gives you a print-ready A4 certificate without templates, Word documents, or design software. Fill in the fields, preview the layout, and export a PDF you can sign and send.
A certificate of authenticity (COA) is a signed document issued by the artist (or their authorised representative) that confirms an artwork is genuine. It records the title, medium, dimensions, year, edition information, and a unique reference number, and is given to the collector at the point of sale.
In most jurisdictions a COA is not legally required, but it is the industry standard for original art, limited editions, and prints. Galleries, auction houses, and resale platforms expect one — and collectors increasingly request it before buying.
Artist name, artwork title, year of creation, medium and materials, dimensions, edition number (e.g. 3/25) if applicable, a unique COA reference number, the date of issue, the collector's name (optional), and the artist's signature. A small thumbnail of the work and a QR code linking to a verification page are common modern additions.
