CoilID

Coilid is a term used to denote a unique identifier assigned to a coil in manufacturing, inventory, and data-management contexts. It is not a formal standard, and its exact meaning varies by industry and company, but it generally refers to a value that uniquely references a specific coil unit within a system of records.

In wire drawing, cable production, and related industries, a coilid enables traceability of material lots from raw stock through processing, coating, and spooling. A coilid may encode or link to attributes such as material grade, diameter or gauge, length, batch or lot, production date, and supplier. In electronics and magnetics, coils such as inductors or wound coils in transformers may be assigned coilids to connect design data, test results, and maintenance history.

In information systems, coilid is commonly stored as a database field and used as a key in ERP, MES, quality management, and inventory systems. Formats vary; some coilids are simple numeric sequences, others are alphanumeric, or GUIDs, depending on the need for global uniqueness or integration with other systems. Barcodes or RFID tags are frequently used to capture coilids on the production floor.

Best practices include defining the scope and lifecycle of coilids, ensuring immutability once assigned, and maintaining a consistent metadata model (e.g., material, dimensions, lot, supplier, inspection status). Proper governance reduces risk of duplication and simplifies recall, warranty, and maintenance workflows.
