If you want to find out your ICQ number or the ICQ number of the interlocutor, you can do it in two ways: through the main interface of the program, and also through an open dialog box with the interlocutor.
Computer, Internet access, ICQ client
To find out your ICQ number, you need to follow these steps. First of all, you need to open the main interface of the program. Pay attention to the top bar of the open window (you need the "Menu" button). By clicking on this button, select the "Profile" option in the list that opens and double-click on it with the left mouse button. Your ICQ number will be displayed in the top panel of the window that opens.
If you want to find out the ICQ number of your interlocutor, you can do it in two ways at once. In the first case, you need to open the main interface of the program. From the general list of contacts, select the person you need and click on his nickname with the right mouse button. A drop-down list will appear with a link "Profile". By clicking on this link, you will see a window in which all information about the contact will be displayed, including his ICQ number.
You can also specify the ICQ number of your interlocutor directly in the dialog box. To do this, you need to do the following. Hover the mouse cursor over the image of your interlocutor and wait for the pop-up menu to appear. The window that appears will allow you to go to the contact's profile, where all information about him will be displayed.
