01023

01023 is a five-digit sequence that appears in several distinct contexts, including postal coding, mathematics, and product or catalog identifiers. As a numerical string, it can be interpreted in different numeral systems or simply treated as a fixed-length code in databases and forms.

In mathematics and computing, interpretations of 01023 depend on the numeral system. As a decimal number with a non-significant leading zero, it can be read as 1023, which equals 2^10 − 1 and factors as 3 × 11 × 31. In environments that use leading zeros to indicate octal notation, such as some programming languages, 01023 would be interpreted as an octal literal equal to 531 in decimal, with a prime factorization of 3^2 × 59. The interpretation thus depends on context and the conventions of the system in which the code appears.

Postal and geographic usage typically treats 01023 as a ZIP code. In the United States, ZIP codes are used by the USPS to designate geographic regions for mail delivery, routing, and administrative purposes. The code 01023 is associated with a western Massachusetts area, and it serves to identify a specific locality within that region in address formatting.

Beyond postal use, 01023 can function as a catalog, model, or part number in various industries. In these cases, the leading zero is often meaningful, preserving a fixed-length code for data management and retrieval.
