Definition	Code that uniquely references this record, allowing reference to this record for this version of this database. Better than a primary key, which is automatically generated by a database and not globally unique. VegBank Accession codes are only generated by VegBank, and therefore data integrity can be guaranteed, unlike with a primary key (number).
