How do I know someone's phone number if they add you in Snapchat by your number?
That sounds like a good idea. What if I don't have any mutual friends with this person?
You can try searching for their phone number online or using a public phone directory. However, keep in mind that this may not always yield accurate or up-to-date information. It's always best to ask the person directly if possible.
