Updated by CPF
CPF Submission Number (CSN) is a unique identifier for CPF contributions and is needed for transactions with CPF Board.
 
Platform operators should apply for 2 CSNs, to submit contributions for the different cohorts of platform workers. For example:
 
  • 123456789-PWA-02 for platform workers who are mandated or opted in to increase contributions, and will receive platform operator's share of CPF contributions
  • 123456789-PWM-03 for platform workers who are not opted in, and contributing to their MediSave only. They will not receive platform operator's share of CPF contributions
