46B

46B is an alphanumeric designation used across multiple domains to label a specific item, route, or category within a system. The combination of digits and a single letter makes it compact and suitable for tagging in databases, catalogs, and inventories. Because it carries no fixed meaning outside its assigning system, 46B must be interpreted within that context.

In transportation and infrastructure, alphanumeric codes commonly designate variations of a route, service, or facility. A transit network might use 46B to distinguish a subroute or a particular timetable service from a related 46 service. In manufacturing and consumer electronics, 46B can function as a model or part number, where the letter indicates a variant, revision, or feature set.

In geography and administration, some countries use alphanumeric codes to label districts, wards, or postal zones, with the digits signaling a broader region and the letter marking a sub-area. In science, standards, and cataloging, 46B may appear as a unique identifier within a larger sequence of records, standards, or library/catalog entries. Other uses include software build or batch identifiers that combine numbers with letters to indicate versions.

Overall, 46B is a flexible designation whose precise meaning depends entirely on the system that assigns it.
