There are a number of services that allow you to query that database. I'm not familiar with reassigned.us

> OSINT Techniques...

Yes that's the one. Its in its 10th edition now I believe, pubbed in 2023. ISBN 9798366360401

Do you have any suggestions for a free tool to query the reassigned numbers database?

Thanks for the help!

Unfortunately I'm not aware of any free tool that lets you query it. Each query costs me a few cents so I try to minimize queries. Twilio has a package available in their API to do this.
