A phone number carries more than it seems: the country and area, the carrier the range was assigned to, the line
type, and often the accounts registered with it.

**Steps**

1. [Scope and legal](https://otinstaller.com/guides/osintverse-community/phone-investigation/01-scope-and-legal.md)
2. [Parse the number](https://otinstaller.com/guides/osintverse-community/phone-investigation/02-parse.md)
3. [Accounts and mentions](https://otinstaller.com/guides/osintverse-community/phone-investigation/03-accounts-and-mentions.md)
