Can you tell if someone is still active on the app? First up, despite what a bunch of paid services will tell you, there is no way to see if someone is on Tinder without an account. Those paid services will either use an account or are not going to be able to deliver what they promised.
Subsequently, can you find someone on Tinder by phone number?
Here’s the short answer: Yes, you definitely can search Tinder by phone number. Even though Tinder makes it clear that you can only look up a specific person if you’re already matched with him or her, you actually can look up anyone if you know their phone number.
Likewise, how do you find out if he has a Tinder account? On Tinder, you can only view another person’s profile if you’re a match. All you have to do to find your boyfriend is enter their name in the search bar in the app, and click on them. One clear sign that he’s still using Tinder is if he’s updated his profile photo and information.
