Narrative:

Original filed ord.mzv.lmn.sln.J18.ipl.BARET4.san. 40 NM southwest of mzv center asked our route. Told center route as above. Reclred to join J18.ipl.BARET4.san. Upon a closer look at our pre departure clearance noticed route to be ord.mzv.J232.irk./.san. Asked ATC if traffic was ever a problem and they said no. Pre departure clearance clearance did not show a revised segment, ie, did not show any dashes or the asterisks boxed that normally is there with a revision to a clearance. The change was not noticed during the before starting engine checklist. Lesson learned, always check pre departure clearance against flight plan.
