2020102123129

2020102123129 is a thirteen-digit decimal identifier used as a unique key in certain data-management and archival contexts. It does not correspond to a publicly standardized code with a single, universally recognized meaning, but rather functions as a practical reference within a given system.

In many implementations, such numeric identifiers are designed to be compact, sortable, and easy to generate in sequence. The fixed length helps ensure consistent storage and retrieval, especially in databases, file-naming schemes, and catalog records. Because the digits contain a dense stream of information, some users attempt to interpret parts of the number as a date or time, but such interpretations are not guaranteed and depend entirely on the issuer’s encoding rules. Without accompanying documentation, the sequence may encode a timestamp, a serial order, or a concatenation of unrelated fields.

Common uses for similar thirteen-digit identifiers include serving as primary keys in relational databases, anchoring filenames in digital libraries, or acting as accession numbers in archival systems. They are typically preferred for their machine-readability and compatibility with systems that require alphanumeric keys without special characters.

Limitations arise when the source and format are unclear. Decoding or validating the meaning of 2020102123129 requires access to the issuing system’s specification or metadata. Absent that, it should be treated as a opaque identifier rather than a self-describing timestamp or code. See also: numeric identifiers, timestamp formats, database keys.
