Bertsio bakoitzak bertsio-zenbaki desberdindua dauka. Programak zehazten badu Lizentzia honen bertsio-zenbaki jakin bat edo bertsio berriago bat aplikatzen zaiola, aukera duzu bertsio horren edo Free Software Foundation-ek geroago argitaratutako beste bertsioren baten baldintzak betetzeko. Programak ez badu Lizentzia honen bertsio-zenbakirik zehazten, Free Software Foundation-ek argitaratutako bertsioetako edozein aukeratu dezakezu.
