How can I get my permanent social security number but have a temporary number and CMU .

Hello Sky,

To access your ameli account, your social security number has to be certified.

So, in your situation, to make sure about the progress your certification, I advise you to contact the CPAM’s English or French Advice Lines.

More information in the following topic: How to call the French Health Insurance Advice Lines?

If your situation allows you to get an ameli account, an operator will help you and give you a temporary code.

Have a nice day.
