A little label.
A bit more context.
Choose a manufacturer-documented rule. Each decoder is limited by brand, appliance market and serial format.
Warranty depends on purchase evidence, product, country and manufacturer terms. A reviewed chart does not confirm the history of an individual appliance.
GE
2 letters + 6 digits + 1 final letter. Only documented years; repeating codes may remain ambiguous.
Café
2 letters + 6 digits + 1 final letter. Only documented years; repeating codes may remain ambiguous.
Bradford White
Water heater: year letter + month letter + 8 digits (2008 onward). Only documented years; repeating codes may remain ambiguous.
Find the right number first.
Look for “Serial”, “S/N” or the equivalent on the product label. Keep the model code too: it helps the manufacturer identify the correct format.
Another brand or format?
Samsung, LG, Whirlpool and other formats are not decoded here yet. An official support listing does not imply serial-decoding coverage.
