OID

The Organisation Registration system (ORS), provides a unique identification number for organisations that want to participate in decentralised actions of the Erasmus+ and/or European Solidarity Corps programmes, the OID. 

The Organisation ID (OID) uniquely identifies your organisation among all organisations participating in the Erasmus+ and European Solidarity Corps actions managed by National Agencies. You can use your organisation’s OID when applying for an accreditation or grant under the Erasmus+ and European Solidarity Corps actions managed by National Agencies

To obtain an OID, the organisation needs to register once in the Organisation Registration system. See the Organisation Registration Guide for details.
