Full name
Address

Billing information
This information is stored by your carrier and sometimes shared with other service providers or databases. Because of this, your phone number serves as a digital identifier linked to your real-world identity.

The registered owner’s name
Associated address (sometimes)
Social media profiles linked to the number
