Catalogue Number
A catalogue number is a unique code you assign to each artwork so it can be identified at a glance, regardless of title changes or similar pieces. Many artists use a simple system that combines initials, year and a running number (for example AJB-2025-0042). The number stays with the work for life and appears on the certificate of authenticity, sales invoice, condition reports and inventory entry. Consistent catalogue numbering prevents confusion between works with similar titles, makes searching your archive instant, and gives galleries and collectors a reliable reference. Decide on a format early and apply it to every work, including studies and editions. Pair the number with strong artwork documentation and metadata so anyone looking up the code can find the full record.
