You don't need a social security number, I think name, date of birth and permanent address are enough for identification. In the past, you would have had to fill a form asking all sorts of questions, including hair and eye color as well ethnic group, weird, eh?
I wouldn't worry about it, I'd just make sure all the registration information is correct on the day of the exam (and that same registration information is re-used consistently on subsequent exams).
The nearest centers listed on Collegeboard's website are in Malaysia, Philippines and Autstralia, not very near I guess.
By the upcoming testing center, were you referring to this one:
INDONESIAN INTERNATIONAL EDUCATION FOUNDATION
MENARA IMPERIUM 28TH FLOOR
SUITE B
JL. HR. RASUNA SAID KAV.1
JAKARTA
INDONESIA
62-2 8317332
IIEF | The Indonesian International Education Foundation
I got this off
The DSST Program, but the institution's website does not list DSST exams under testing (from what I could gather), typical.
Anyways, I'd call them up and ask if they can provide CLEP exams, even as favor (they already deal with Collegeboard for SAT exams so they might be able to order the paper based version or maybe even better, get them online).
