Ontario Education Number (OEN)

The Ontario Education Number (OEN) is a unique numeric identifier that has been assigned to students in Ontario's elementary/secondary education system by the Ministry of Education since 2003. Use of the OEN is currently being extended to publicly funded colleges and universities across Ontario. This webpage provides post-secondary institutions access to key OEN supporting documents. Colleges and universities are strongly encouraged to review all OEN supporting material.
