Can you list certifications PMP on your resume if you have passed the test but haven't received your certificate yet?

Yes, you can - as long as you have the "Exam Passed" report from the exam center where you passed the exam.

Usually your name will come up in PMI's global directory for PMP holders within 2-3 working days of you passing the exam. So, people who see the certification in your resume can easily verify if you are really a PMP holder.
