    Serial numbers in bicycles are manufacturer-specific and generally useful only if you already know the manufacturer, and they either have a known formula for the number or have kept records and are willing help. – ojs Feb 6 at 7:44

There is not enough information in the picture to give any real answer.

However we can tell its an ashtabula, or one-piece crank. This is a sign of a low-end bike, or possibly an old one (ie 1960s or earlier.) Modern bikes use a 3 piece crankset where the crank arms are bolted to a spindle.

The paint looks good in the photo, without wear and tear. And the stamped serial number is regular and lined up, not the slightly ragged result of a hand-punched number done one digit at a time.

Upshot - cheap nasty BSO bike made in China or some other Asian country.
