No. If you are using the site properly, your phone number will not be visible to anyone. The only visible information is your username, and even that can be Anonymous if you so choose. The best way to protect your privacy is to use a disposable phone number when signing up for any online service that requires a phone number. This way, even if your information is compromised, it will not be traceable back to you. While Omegle does its best to protect user privacy, it is always best to take extra precautions when using any online service.
