Since 1 January 2009, all entities registered in Singapore can transact with government agencies using their Unique Entity Numbers (UEN). The UEN is like the NRIC number of the entity for identification purposes.
To transact with CPF Board, employers will use the CPF Submission Number (CSN), which comprises the “UEN + CPF Payment Code”. The CSN also identifies the types of payments that employers are making to the Board.
For employers who are individuals hiring local employees e.g. personal driver, gardener, local domestic worker etc., the CSN is the “NRIC/Foreign Identification Number (FIN) + CPF Payment Code”. For individuals hiring foreign domestic workers or the self-employed, the CSN is the NRIC/FIN.
