0820

0820 is a four-digit numeral that can refer to different things depending on context. In decimal notation it represents the integer 820. With a leading zero, as is common in fixed-width codes, the sequence is often treated as an identifier rather than a value. The prime factorization of 820 is 2^2 × 5 × 41, and it has twelve divisors.

In information management and manufacturing, 0820 is frequently used as an identifier, catalog number, or part/model code. Such four-digit sequences are common in inventories, databases, and product labeling because they fit easily into standardized formats and allow for systematic categorization or batching. The same sequence may appear in different domains (for example, as a file code, customer ID, or shipment label) without implying a shared meaning across systems.

In timekeeping and dating, 08:20 represents a specific time of day. In date formats that use month-day sequences, 08/20 can denote August 20. In other calendar conventions, the sequence might appear in different contexts, such as a shorthand for a year or a project milestone, depending on the local formatting rules.

Coded and regional uses vary by country and organization. Four-digit codes like 0820 can function as postal or geographic identifiers within particular systems, but the exact location or purpose is not universal and depends on the issuing authority or database.
