There are around 4,000 test centers all over the world. All detail information on test centers for TOEFL test is available at TOEFL test’s official website. Here is the link: http://www.ets.org/bin/getprogram.cgi?test=toefl. I found even properly managed information with phone number, fax number, e-mail address, URL, and other contact details with addresses of test centers here: http://www.abroadeducation.com.np/test-preparation/toefl/test-centers.php. I hope these two websites will help you with your question.
