Law / Getting a PESEL without registration in Poland [7]

Merged:

PESEL with Poland's work contract

Good Evening!

I live in Krakow and due to a change of Job now my PESEL is required, so anyone has any suggestion how to do it, considering my landlord for avoid taxes did not make me a contract? could I go with my actual job contract to the Katowice (where my actualy job is) for make the PESEL without any residence registration? is my contract enough together with my ID?

Thank you very much to everyone. PS i read that not you need a notary to confirm your workplace contract or something like that
