Well it is not a squire. If you go to www.fender.com you can get the year of manufacture from the serial number. There should also be a year (and month) written on the neck (under the neck joint) and on the body (either under the neck joint or under the pick guard). If they all match up then it is probably ligit.

Another thing is that the guy who put it together will have initialed the dates on the neck. You can ask tech support at fender if these initials are good for the corresponding date.
