Appliance411 API Alternative — Programmatic Appliance Data for Software Teams
Appliance411 is a trusted consumer tool for looking up appliance date codes. ApplianceAPI provides the same intelligence — and more — as a developer-ready REST API.
Appliance411 has been a go-to resource for home inspectors, repair technicians, and consumers looking up appliance age from serial number date codes. But Appliance411 is a manual website lookup — there is no API. ApplianceAPI provides the same serial number decoding, plus photos, specs, dimensions, and recall checking, all accessible programmatically via REST API.
From Manual Lookups to Automated Workflows
Home inspectors, repair technicians, and property managers have relied on Appliance411 for years to manually decode serial numbers and estimate appliance age. The process works — visit the website, find the brand, enter the serial number, read the date code table — but it is manual and cannot be integrated into software.
ApplianceAPI automates this workflow. Send a brand and serial number to the API, get back the manufacture year, month, confidence level, and algorithm explanation in a structured JSON response. Integrate it into Spectora, ServiceTitan, your CRM, or any software that handles appliance data.
If you are currently alt-tabbing between Appliance411 and your inspection or dispatch software, ApplianceAPI eliminates that manual step.
More Than Date Codes
Appliance411 focuses on serial number date code lookup. ApplianceAPI starts there and adds:
- Product photos — Verified appliance images by model number, embeddable in reports and tickets.
- Specs and dimensions — Height, width, depth, capacity, and feature data.
- CPSC recall checking — Cross-reference against the official CPSC recall database with relevance scoring.
- Model verification — Catch typos and invalid model numbers before they enter your database.
- Kenmore OEM routing — Automatically identify the OEM manufacturer from Kenmore model prefixes (665 = Whirlpool, 795 = LG, etc.).
Built for Inspection and Service Software
If you build or use home inspection software (like Spectora or HomeGauge), repair dispatch platforms (like ServiceTitan or Workiz), or property management systems — ApplianceAPI is designed to plug into your existing workflow. One API call returns everything you need for an appliance record: photo, age, specs, recall status, and confidence level.
No more manual lookups. No more copy-pasting from Appliance411 into your report software.

Frequently Asked Questions
How do I decode an appliance serial number?
Use the free ApplianceAPI age decoder at applianceapi.com/appliance-date. Enter the brand and serial number to get the estimated manufacture date, month, and confidence level. The same data is available via REST API for software integration.
Does Appliance411 have an API?
No. Appliance411 is a consumer-facing website with no API or programmatic access. ApplianceAPI provides the same serial number decoding functionality (and more) as a REST API.
Can you tell how old an appliance is by the serial number?
Yes, for most major brands. Appliance manufacturers encode the manufacture date in serial numbers using brand-specific patterns. ApplianceAPI decodes 60+ brands across 22 algorithm families.
What is the best free appliance age finder?
The ApplianceAPI age decoder (applianceapi.com/appliance-date) is free to use and covers 60+ brands. Appliance411 is another free option but is limited to manual website lookups and covers fewer brands.
How does Kenmore serial number decoding work?
Kenmore appliances are manufactured by different OEMs. The first 3 digits of the model number identify the manufacturer (e.g., 110 = Whirlpool, 795 = LG, 363 = GE). ApplianceAPI automatically routes Kenmore serial decoding to the correct OEM algorithm.
