The 12-digit PPO number is unique for every pensioner. It acts as a reference number for any communication made to Central Pension Accounting Officer (CPAO). Pensioners have the facility to monitor the status of their pension and file for grievances through the PPO number as the CPAO database can recognize the 12 Digit PPO numbers. CPAO was established on 1st January 1990 and, therefore, does not have a record of pensions before 1990.
If you are a pensioner who retired before 1990, you can be added to the CPAO database's list for retirees prior to 1990. The details of such pensioners can be submitted by the PAO of the pensioner's parent office or the related CPPC, accompanied by authenticated photocopies of old pension papers, in order to obtain a 12-digit PPO number.
