PMP certification is valid for 3 years. To renew every 3 years, you need to earn and claim 60 Professional Development Units (PDUs) from PMI. Also, a renewal fee of $60, if you are a member of PMI or 150$ if you are not a member needs to be paid. Once done, a new PMP certificate with new expiry date will be sent via postal mail to the registered address. PMP License Number remains the same.
