What is an application number?
An application number is different from a unique client identifier (UCI) or client ID.
If you have multiple applications with us, they’ll have
- the same UCI or client ID
- different application numbers
An application number is specific to your application. We send it to you when we start processing your application.
To find it
- look at the top corner of the letters you receive from us, such as
- the acknowledgement of receipt letter (we send this after you submit an application)
- an invitation to a citizenship test or ceremony (a letter or an email)
- other letters
- sign in to your account if you applied online (under View the applications you submitted or Account messages section)
Application numbers usually have 1 letter and 9 numbers. For example:
- Citizenship: C123456789
- Work permit: W993830598
- Economic class: E099977028
