Serial number dating / Supro
Supro serial number lookup
Find the year a Supro was built, read from Supro’s own numbering scheme.
Can't read a digit? Type ? in its place. Looked-up serials are kept, never tied to you. How it works
Type the serial or code from the instrument. We read it as you type.
Cross-check with a pot code
The number stamped on a potentiometer inside the guitar. It dates the part, not the whole instrument.

How sure is it
Every result carries its confidence. Treat the year as a strong guide, not proof: a serial can be replaced, a neck and body can be from different years, and reissues copy old numbering. For anything that matters, confirm the year against the neck date, the pot codes.
