An official passport is a passport which is issued to someone who must travel internationally on official state business. These passports are issued specifically to people who need to travel, rather than to people who are being assigned or posted overseas.
In the bottom right corner of the page with your photo is a section labeled authority. My present passport has United States Department of State before that I had one that said something to the effect of Boston Passport Agency. My Irish passport doesn't have that section so if it isn't a US passport you may not have that section BUT my wife's ROC passport has something like TECO SF, CA. Good Luck!
