Unique Client Identity UCI Got 8 Digits But Others Got With 10

[Gurpinder]

I recently applied study permit for the first time along with my classmates. I got my UCI with 8 Digits while others got with 10 Digits. Why it happened this way?

Make sure with your parents if they may have applied for Canadian immigration under any temporary or permanent category for themselves and for you. The computer system may have picked you with your date of birth. If you or your parents never applied for Canadian immigration under any category, you need not worry about it. What happens sometimes, a person who had UCI in the past gets a new UCI for some reason. For example, someone was not using surname earlier and had a UCI without surname and now added surname and did not declare the previous UCI. When IRCC officer detects it, confirms with the documents and person and administratively confirms the new UCI for the person and releases the previous UCI in the pool of UCIs. When someone applies like your case, gets that old 8 digit UCI which was available in the computer database pool. It happens very rare; therefore, only very rare persons experience this. It may also be possible that there is another person by the same name as you are and same date of birth; therefore, computer picked you considering the other person.
