Platform operator CPF Submission Number
What is a platform operator CPF Submission Number?
  • The platform operator CPF Submission Number (CSN) is a unique identifier used by platform operators to transact with CPF Board. 
  • This includes making CPF payments for platform workers and submitting requests on platform operator matters.
  • A CSN consists of a Unique Entity Number (UEN) and CPF payment code.
  • The CPF payment code identifies the type of payment made.
  • Only platform operators need to have a platform operator CSN.
  • If you are unsure whether you meet the definition of a platform operator, you may use MOM's self-assessment checklist.
