U00000045

U00000045 is an alphanumeric identifier used in various information systems to denote a unique item or record. Because it does not convey domain-specific meaning on its own, its interpretation depends on the surrounding data schema and documentation.

The format consists of a leading "U" and eight hexadecimal digits. Fixed-width, hex-based identifiers are common in software and databases because they sort predictably and map well to numeric storage. In contexts where the suffix is treated as a hexadecimal code, 00000045 corresponds to the value 0x45; if mapped to Unicode, this can be interpreted as U+0045, the Latin capital letter E, though such mapping is not universal and depends on the system.

Common usage includes serving as database primary keys, inventory or asset tags, and dataset or test identifiers. It may also appear in software configuration, versioning schemes, or catalog records in libraries and archives. Because many systems reuse similar prefixes, U00000045 is not inherently meaningful beyond its intended scope.

For accurate interpretation, refer to the specific data model, schema, or metadata accompanying the record in question. Where there is ambiguity, contact the data steward or system administrator.
