The Organisation ID (OID) in Organisation Registration system
The OID is generated when registering a new organisation in ORS. The OID is an 8 digit sequential number prefixed with an E and is attributed to organisation information once registered in ORS (for example: E12345678). All organisation details, contacts, annexes and authorised users (users who manage the organisation details in ORS) must be managed via ORS.
See Organisation Registration Guide.
The Organisation ID (OID) in Application forms
All application forms require an organisation's OID. In some forms, participating organisations other than the applicant organisation may or may not need an OID. The options depend on the specifics of the action type and call year.
See Submission phase for details.
