Reverse Phone Append
Starting from a phone number and looking up the matching person, their name, and related contact details.
Definition
Reverse phone append takes a phone number as the input and returns the associated person and their data, such as name, address, email, or line type, by matching against identity and carrier datasets. It enriches records that only have a number. Because phone outreach carries strict compliance duties, Trackyr only runs reverse phone append when a hunt explicitly opts in, and it never fires automatically.
How reverse phone append works
Reverse phone append (also called reverse email append when keyed on email) backfills a phone number onto a contact you already have an email for. It matches the known identifier against phone datasets and returns a number, which should then be line-typed (mobile vs landline vs VoIP) and DNC-screened before you dial or text. On Trackyr, append is opt-in per hunt, charged only on a successful match, and the returned number is line-type verified via PhoneValidator so you know which channel will actually connect.
Common questions
Is reverse phone append accurate?+
Match rates vary by dataset and region. Accuracy improves when the returned number is line-typed and validated, rather than returned raw — a verified mobile is far more actionable than an unknown number.
Do I get charged if there's no match?+
On Trackyr, reverse-append is charged only on a successful match, so unmatched lookups don't cost you.
