= Serial numbers
{wiki=Serial_numbers}
Serial numbers are unique identifiers assigned to individual items, products, or pieces of equipment. They serve several purposes, including: 1. **Identification**: Serial numbers help differentiate one item from another, even if they are of the same model or make. This is particularly useful in inventory management and quality control. 2. **Tracking**: Manufacturers and retailers can track the production, sale, and ownership of an item over its lifecycle. This can be helpful for warranty claims, recalls, and service history.
