Appliance Data Glossary — Terms and Concepts

A model number is an alphanumeric identifier assigned by the manufacturer to a specific product configuration. It identifies the appliance type, features, color, and series. Model numbers are used to look up specifications, order parts, and verify warranty coverage.

A serial number is a unique identifier assigned to an individual appliance unit during manufacturing. It encodes the manufacture date, production plant, and sequence number. Serial numbers are used to determine appliance age and verify warranty status.

Each appliance manufacturer encodes the production date in the serial number using a proprietary format. ApplianceAPI maintains decode algorithms for 55+ brands that extract the manufacture date automatically. The system returns the date with a confidence score.

Appliance age lookup determines how old an appliance is by decoding its serial number to find the manufacture date, then calculating the elapsed time. This is used by inspectors, warranty companies, and property managers to assess remaining useful life.

Recall checking cross-references an appliance model number against the CPSC (Consumer Product Safety Commission) recall database. If the model has been recalled, the API returns recall details including the hazard description, remedy, and recall date.

Appliance metadata is structured information about an appliance model: brand, type, product title, specifications, dimensions, images, documentation links, and recall status. It is the data layer that powers service software, inspection tools, and inventory systems.

Appliance data infrastructure refers to the systems and APIs that collect, normalize, and serve structured appliance information. ApplianceAPI is an example — it aggregates data from manufacturers, retailers, and government sources into a single REST API.

Appliance control APIs (smart home APIs) send commands to connected appliances — start a cycle, check temperature, receive alerts. Appliance data APIs return information about appliances — model specs, serial decoding, photos, recalls. They serve different purposes and different audiences.

Appliance specs include physical dimensions (height, width, depth), capacity (cubic feet, load size), weight, energy rating, noise level, and feature details. These are used for install planning, product catalogs, and compatibility checks.

A confidence score indicates how reliable a data match is. ApplianceAPI assigns confidence scores (high, medium, low) to image matches based on source quality, verification status, and match precision. High-confidence results have been human-reviewed and verified.
