While filling the Internet Reimbursement (IR) registration form, I noticed that I will need to include a CPF Submission Number. What is a CPF Submission Number (CSN)?
The CSN is a unique 15-digit alpha-numeric reference number provided by the Board to a registered company for the submission of employer contributions. It comprises your company's Unique Entity Number (UEN) and CPF Payment Code.
If you are unsure of your company's CSN, please approach your HR department for assistance.
