There are several ways to specify the apartment number (nnnn).

1. Four digits (nnnn) is the number on your door and post box. It is always used together with your address when dealing with public authorities and when ordering items for delivery by post and courier. Authorities call it the official apartment number or just the apartment number.
2. Five digits (x-nnnn) is the way you communicate with the association which calls this apartment number.
3. Nine digits (yyyy-x.nnnn) is the way you communicate with our property and financial manager who calls this the contract number.

Five and nine digits indicate the stairwell (1-7) where you have your post box and the number of the property (1111-1113).
