rešenje o registraciji

1. registration decision
   U banci su tražili rešenje o registraciji iz APR-a. — The bank asked for the APR registration decision.
   Odštampao sam rešenje o registraciji da otvorim račun. — I printed the registration decision to open an account.

It is an administrative decision of the APR, but in practice it serves as the certificate of registration: banks, business partners and state bodies ask for it. Don't confuse it with "poresko rešenje", the tax office's decision on tax amounts.
