Currently, many projects require that a project manager has to hold PMP certification which is one of the best international certification in Project Management that is provided by The Project Management Institute (PMI). However, in my country some parties in order to win the bid often use 'fake' PMP certification. 'Fake' PMP certification DOES NOT mean other certifications that provided other institutions besides PMI, it means that this certification should be legally provided by PMI, but some parties create their own PMP certificate based on the real one. They easily change the name to put on the certificate meanwhile the person that they put on the certification never take or didn't pass the exam.
In order to prevent some parties continuously faking the certification, I would to give some information how to check the person who legally hold the certification. You can easily check on pmi website www.pmi.org or click the link certification.pmi.org/registry.aspx .
On the link I mentioned before, you can fill last name of the person that you want to check. You may also filter your search using first name, credential and country. If the person with the correct last name off course is a PMP or other PMI certifications holder, the name is automatically showed on the screen, if s/he does not hold the certification provided by PMI, her/his name will not show. You can an example below
Hope this help
