Reverse Phone Lookups - How to identify linked platforms when there is no SMS or email trail?

I am trying to map out my digital footprint for a phone number I’ve owned for several years. I want to identify which specific apps, social media platforms, or websites have this number registered to an account.

Unlike email lookups where you can search an inbox for marketing emails, this number has no incoming SMS history or marketing alerts to follow. I’ve identified a few accounts by memory, but I’m hitting a wall with the rest.

I'm looking for browser based tools or tools that run on Chomebook (ChromeOS) or Linux.
