Item Assist supports fast serial decoding first, then model-based Smart Lookup when the label is missing, worn, or incomplete.
The most accurate path is still the serial decoder because many manufacturers encode month and year directly into the plate.
If the serial label is unreadable, Smart Lookup can still estimate the age window using model family timelines, release patterns, and general product context.
Have the serial number? Use the decoder. Only have the model or description? Use Smart Lookup.
