You were informed of the phone number belonging to your o2 DSL connection with the o2 order confirmation by letter and/or e-mail. The German term is "Rufnummer". 
You can also find your phone number in the menu of your o2 Homebox or AVM Fritzbox. See manual. 

If you have access to your bill, what exactly is your problem?

Problem is i am not able to see my contract  by login to my 02 even i have tried my email id >emailadress removed] it showing no data or contract details .

Also i have checked my 02 homebox 6641 but did not find any phone number on it .

so i would i see my contract details ?

please correct my login details ,

Edit o2_Larissa: Email address removed for privacy reasons

All o2 Homebox obtain the phone number automatically through the o2 remote configuration. This is also the case with your device. If you did not find the phone number, you obviously did not access the o2 Homebox operating menu. By looking at the white plastic housing, you can not read your phone number. See manual. 

Hi @ibrar_mohd 

Welcome to our o2 Community. When you access the router web gui via Internet browser ( open o2.box in your browser while connected via wifi with the homebox) you can login on your router to check the settings and to look op for further information as for example your fixed line or landline number (in germen so called “Festnetznummer”, which you need to log in on our website to see you account)
