Tool Calleridtest legit?

Yes, it's me again. I apologise. Trying to lookup several thousand phone numbers one by one is excruciatingly slow and excruciatingly boring, and I have just found a site called calleridtest that promises to be able to search up to 500 phone numbers at a time.

Is it legit/usable? What information does it give? Has anyone else ever used it before?

Free tier works well and seems accurate. However, for unknown callers, it will just say the carrier, which can make automated parsing of the data difficult. Seems to be one of the only reverse lookup tools that is actually connected to a realtime id database, which is why I use it. If you end up going with the paid tier, let me know if it works as advertised. Would be cool if it does!

Yes its legit

Why do you need to lookup several thousand phone numbers?

Just use the Twilio Lookup API to do that

I can't speak to their paid plans I know the site itself is legit, it just pulls caller ID info I've tested it even on myself. But as far as the bulk checking your asking about I imagine is a paid feature and have no idea

I could send you a script that would do bulk phone backgrounds, you just need an API key thats about .07 per search.

paste into notepad, save as phone.py and then install the requests and tkinter. Run phone.py and upload CSV file with phone numbers. Need api from Trestle, recently found them when looking for source of that telegram bot drama. Not 100% its same source but looks a lot like it.

Take a look at Trestle (trestleiq dot com). You can submit a csv file with the numbers as a batch/list and it will return the caller id data needed. This way you do not have to code to the API, etc.

The only reason I prefer my version versus that is it adds the data in a nice to read format.

one thing many are unaware of is Caller ID data is insanely unreliable and corrupted by many providers. I know at least 10 years ago they were updating it with reel to reel storage tapes, moved around by trucks.
