255a

255A is an alphanumeric designation used across multiple domains. Without context, it does not identify a single, universally recognized item.

In transportation, 255A can appear as a route or service number within a city’s transit network. Such numbers are often assigned to passenger lines, shuttles, or variations of a main route, and may denote special schedules or limited-stop service.

In electronics and engineering, 255A is a common style for model or part numbers. It may identify components such as sensors, connectors, adapters, or integrated circuits in catalogs. The exact specification depends on the manufacturer and product line.

In real estate, construction, and postal contexts, 255A may designate a unit, suite, or parcel (for example, a building unit such as “255A Main Street” or a lot number). It can also appear as a cadastral or zoning identifier in maps and records.

Other uses include publications, standards sections, or regulatory references where alphanumeric codes label clauses or items. Because codes are highly contextual, 255A can have different meanings across sectors and regions.

To determine what 255A refers to in a given instance, note surrounding information such as location, industry, and any accompanying numbers or letters. Consulting relevant catalogs, maps, transit schedules, product databases, or official records can help identify the specific reference.
