Use cases
Phone validation use cases
One lookup tells you whether a US or Canadian number is mobile, landline or VoIP, which carrier serves it after porting, whether a carrier deactivated it recently, and whether it can take a text. Add the TCPA litigator scrub for 1 credit, or the state DNC and complainer checks for free. Which fields matter depends on what happens next: a dial, a text, a lead sale or a new account.
