Accession Number Definition (Historical Context)
An Accession Number is the unique and permanent identifier given to an object when it enters a collection. It serves as the primary reference key for all records related to the item. This number typically includes the year of acquisition and a sequential count. The number links the physical artifact to its legal documents, provenance, and catalog details. It ensures that the object can be tracked indefinitely within the institution.
Origin of the Word “Accession Number”
The term combines the word “Accession” (formal addition to a collection) with “Number” (a unique digit string). Accession comes from the Latin accessio, meaning “a coming to.” The unique number ensures that the item can be accurately distinguished from all others in the entire collection.
Examples:
General Use: “In addition, the label displayed the artifact’s permanent Accession Number clearly.”
Archival Context: “Similarly, the librarian used the Accession Number to locate the box containing the 19th-century letters.”
Curation Context: “Consequently, the object cannot be borrowed or moved without first recording its Accession Number in the system.”
Security Context: “Moreover, security personnel used the unique Accession Number to verify the statue’s identity.”

Accession Number Historical & Cultural Context:
The use of Accession Numbers became standard practice in the late 19th and early 20th centuries. Before this, systems for tracking artifacts were inconsistent and often chaotic. The adoption of a systematic numbering process professionalized museum management globally. This unique number is now recognized as the legal anchor for a cultural object. It ensures that provenance and ethical sourcing can be monitored across centuries.
Principles or Key Aspects of Accession Number:
- Uniqueness: The number is never assigned to any other object, past or future.
- Permanence: It remains linked to the object even if the object is deaccessioned.
- Simplicity: The format is usually simple: Year.Sequence.Part (e.g., 2025.1.2).
- Integrity: It protects against confusion and helps prevent the illegal swapping of artifacts.
- Record Linkage: The number is the primary mechanism for retrieving all related documentation.
Ethical Considerations for Accession Number:
- Transparency: Institutions should make Accession Numbers publicly searchable to aid research.
- Looting: A clear number and documented provenance help prove an item’s legal status.
- Repatriation: The number is essential when identifying and tracing items for repatriation claims.
- Falsification: Fabricating an Accession Number or its records is a serious ethical violation.
Relevance to Ancient Worlds
The Accession Number is crucial for understanding ancient worlds because it:
- Secures Context: Permanently ties an ancient artifact to its initial excavation data.
- Prevents Loss: Ensures that items tens of thousands of years old are not misplaced.
- Aids Study: Allows international scholars to accurately cite and reference objects across collections.
- Protects Heritage: It creates an auditable record that deters the illegal trade of antiquities.
