    OTO ID – the number of the fiber optic cable outlet

    We need to have your OTO ID in order to be able to activate fiber optics Internet in your home.

    • The ID number is printed directly on the outlet
    • It generally starts with the letter A or B, but sometimes also with the letter O or the letters WP, followed by ten digits in the following format: A.XXX.XXX.XXX.X.
    • If you have any problems here, your building management company or the previous tenant can give you the information you need.
