Q. What is a CoE code?

The Confirmation of Enrollment code, or CoE code for short, is an important element in the application process for international students seeking visas to study overseas, especially in Australian education. 
A CoE is an electronic document issued to international students who would study, thereby registering educational providers like universities. This document has a unique identifier - the CoE code.
However, to acquire an official Confirmation of Enrolment, there are several prerequisites. First, it is necessary to formally accept the offer of study from the university. The student's formal acceptance shows that he has passed admission screening, making his application a done deed. 
In addition, compulsory Overseas Student Health Cover (OSHC) must be purchased at the standard rate for the duration of the visa, and tuition has to be settled by semester for just one term. Once it has completed these steps, the educational institution will issue an official CoE. This is accepted as evidence of enrolment when applying for a student visa through the Australian Government's Department of Home Affairs and is your only valid proof that you are entitled to study in Australia.
The CoE code carries important information, including the student's name and personal details, as well as the course and length of intended study. The CoE is an important part of the visa application process, but you need a valid one to get a student visa.
In short, the CoE code is a special number attached to the Confirmation of Enrolment form, which all international students need for their visa application in Australia. This verifies that students have met all requirements and also certifies their enrollment in an educational institution. 
The Australian Government uses this information to process the student visa application form submitted by applicants.
