I think PMP renewal is necessary. If you want to think that most of the candidates spent a lot of time and energy to obtain the PMP certification, not to mention the PMP exam registration fee. And the training costs of PMP.
If the PMP certificate is invalid, then you can only retake the exam to get it again, and you say you have no loss. Although you may think that you may not be engaged in this management work in the future or that you will not use it anymore, but you all know that what you hold in your hand is the most real thing, and it will be useful someday. Right.
Prerequisites for PMP renewal:
In a period of three years, if 60 PDUs are full, PMI will send a renewal letter to the PMP holder’s email address. Letter title is "You are eligible to renew your PMP® credential", telling you that you can renew your certificate.

PMP renewal requires credit card payment, the card must have a U.S. dollar account (at least $150), and support U.S. operators, such as Visa, Master, etc. (you can call the bank); at the same time, you must have an English mailing address so that PMI can transfer the new The certificate is mailed to PMP.
