Where is the serial number on my Callaway club?
The serial numbers for Callaway clubs are located on the heels of their clubheads near the hosel. Please note that the serial number for a set of Callaway irons will only be on the clubhead of the 8 iron. Additionally, at this time Callaway is only serializing the 3 woods and 3H hybrids in our fairway wood and hybrid lines.
