14591507

14591507 is an eight-digit decimal numeral commonly used as a unique identifier in various information systems. As a stand-alone string, it carries no intrinsic meaning and does not identify a specific object unless it is assigned within a particular catalog, database, or context. Such numbers are common in digital record-keeping and inventory management.

In databases and catalogs, eight-digit identifiers serve as primary keys, accession numbers, or serial numbers. They are typically allocated sequentially or via a centralized registry, and may be embedded in URLs or API calls to retrieve the associated record. The same numeric format can appear across distinct domains, but the meaning is determined by the system using it.

In biomedical literature databases such as PubMed, numeric identifiers are called PMIDs. The sequence 14591507 is within the range of PMIDs assigned in the early 2000s, and in PubMed it would resolve to a particular bibliographic entry. PMIDs are unique within PubMed and do not convey bibliographic metadata themselves.

Other uses include product catalog numbers, library or museum accession numbers, and parts inventories. Some systems implement validation checks such as length restrictions or check digits, while others rely on database constraints. The duplication risk is mitigated by unique constraints in the relevant registry.
