I already have a CPF Submission Number (CSN) to make contributions for my employees. Can I use the same CSN to make contributions for my platform workers?

No. Each CPF Submission Number (CSN) has a unique payment code that identifies the different payment types made by platform operators to the Board.
For example, you will use the following to submit CPF contributions:
- 123456789-PTE-01 for employees
- 123456789-PWA-02 for platform workers who are mandated or opted in, and the contributions will be allocated to all CPF accounts
- 123456789-PWM-03 for platform workers who are not opted in, and the contributions will be allocated to their MediSave account only
Please apply for new CSNs for the purpose of making CPF contributions for platform workers. To apply for your new CSNs, please refer to CPFB | How do I obtain my CPF Submission Number (CSN) as a new platform operator? How long does it take?
