Reverse Append
Backfilling a phone number from an email address on a contact you already have.
Definition
A reverse append takes a contact you already hold, most often an email, and returns a current phone number matched from a consumer or business graph. It's not the same as locating a stranger from scratch: it enriches records you already own. On a skip-traced or owned list, it fills the email-only rows with a callable number, then line-type validation confirms it.
Put reverse append to work.
