Organization must have status LEAR (legal entity appointment representative) for participate in the calls of Horizon 2020. And the European Commission does not sign the grant agreement with you, if you do not have an Participant Identification Code (PIC). Therefore, we recommend you take care of this in advance.

Those organizations, that have already signed a grant agreement and get their PIC, do not need a new one.  Check you before registering: perhaps, the organization already has a PIC. Such a test can be done at link: http://ec.europa.eu/research/participants/portal/desktop/en/organisations/register_sec.html
