jelzszám

jelzszám is a Hungarian term derived from the words jelzés (signal or indication) and szám (number). It refers to a designated numeric identifier assigned to a particular signal, code, or reference within a system. The concept is commonly found in fields such as telecommunications, radio communications, emergency services, and logistics, where precise identification of signals or messages is critical.

In radio and telecommunication, a jelzszám may be used to catalogue different frequency bands, modulation schemes or protocol messages. For example, a beacon transmitter might have a jelzszám to uniquely distinguish it from other beacons on the same frequency. In emergency dispatch systems, each type of incident or response vehicle can be assigned a jelzszám to streamline data entry and reduce ambiguity. Logistics and inventory management systems may also employ jelzszám for tagging goods, where the number encodes product type, batch, and destination details.

While the use of jelzszám is most evident in technical and professional contexts, it also appears in more informal settings when users refer to operating codes, calibration numbers, or testing parameters. The uniformity provided by jelzszám systems makes communication more efficient and helps prevent errors in high‑stakes environments.
