Yesterday I received my social security number in the post. Hooray! However, after reading your responses, I realised that it was a temporary number (5 zeros).
When I tried to use it to create an account on autoentrepreneur.urssaf.fr or on ameli.fr, it wouldn’t work.
I’m confused by the issuing of a temporary number. Is there any reason why a temporary number is issued if nothing can be done with it? Does it have any use?
