When you pass PMP, pay special attention to the congratulatory email you receive from PMI because it contains link to order your complimentary PMP label pin.

PMP label pin is not automatically sent when you pass the exam and you have to order it for free using the link given in email.

I received my ceritificate yesterday and inside there was a letter which mentioned about label pin and I was like WTH!!

Then immediately I checked my email and ordered the pin which will arrive in 6 to 8 weeks.
