We requested takeoff data for and departed runway 21; but did not note the displaced threshold for runway 21. Our takeoff data was based upon using that area. We departed where the taxiway meets the runway departure threshold; resulting in approximately 1;300 less runway than planned. Contributing to the situation was a lack of runway edge lighting in the threshold area giving an impression that there was nothing there to be used.
Dispatch planned fuel stop in ZZZZ; prior to departure studied as much as possible regarding operations there; there are no 10-1 or 10-7 pages for ZZZZ; checked the Operating Manual to no avail as well. There are no taxiway designations on either the 10-9 page or the airport itself; the parallel taxiway ends approximately 1;300 feet from the end of the runway; however; on the 10-9 page this not apparent; as it is covered by the depiction of the approach lights; additionally; this portion of the runway has absolutely no lighting; as we got to the end of the taxiway; it appeared that we were in fact at the end of the runway.
