90101

90101 is a five-digit numeric string that can function as an identifier in multiple contexts. It does not have a single, universally recognized meaning on its own, but may appear in postal systems, product catalogs, data records, or other coding schemes.

In postal and geographic contexts, five-digit codes are commonly used to designate specific delivery areas. In the United States, ZIP codes are five digits; if assigned, 90101 would identify a particular region for mail routing. ZIP codes can be further refined with a ZIP+4 code to specify a more precise location within that area. The leading digit of a US ZIP code describes a broad region, with subsequent digits narrowing the designation to state and locality.

Beyond mail, 90101 often serves as a catalog, inventory, or database identifier. In these systems, the number is commonly used as a primary key, SKU, item number, or reference code. Its meaning is defined entirely by the organization or software that assigns it.

In literature, media, or numerical datasets, 90101 may appear as a fictional code, an archival reference, or part of a sequence used for indexing. Unless accompanied by context, the code does not convey information beyond its role as an identifier.
