Phone append costs $0.02 to $0.03 per matched record at self-serve vendors, as publicly advertised on DataZapp’s and Tracerfy’s own pricing pages as of October 2026, with unmatched records not billed. A phone append is the service that adds a phone number to a record that already has a name and address. The rate is easy to find. What is harder to find is what the vendor counts as a match — and that word, not the two or three cents, decides what a call center actually pays per conversation.

Tracerfy sells its product as skip tracing, but a Normal Trace takes the owner’s name and address as input and returns phones, which is an append in everything but the label. The full DataZapp rate card, including its match report before purchase, is read in DataZapp pricing, and Tracerfy’s other tiers in Tracerfy pricing.
Per match and per record are different prices
The first two vendors bill only matched records. Melissa’s published enrichment subscription is an allowance of records a year. If every record you submit counts against that allowance — ask Melissa whether it does — then the price per matched phone depends on your match rate, and the arithmetic is simple division. $14,300 over 1,000,000 records is $0.0143 a record.
| Share of submitted records that come back with a phone | Effective price per matched phone at $0.0143 a record |
|---|---|
| 80% | $0.018 |
| 60% | $0.024 |
| 40% | $0.036 |
The match rates in that table are inputs for the division, not measurements of any vendor. The point is that a per-record price and a per-match price cross over somewhere in that range, so neither is cheaper until you know your own match rate on your own file.
What a match is, and why it moves the real price
Every vendor on this page bills a match the same way: one charge per record that came back with a phone. What qualifies as coming back with a phone is where they differ, and the possibilities run roughly from loose to strict:
- Any phone ever associated with the address.
- Any phone associated with the surname at the address.
- A phone linked to the exact person you supplied.
- A phone linked to that person, with line type and recent activity returned so you can tell a live mobile from a dead landline.
A file appended on the first definition can show a higher match rate than one appended on the fourth and still produce fewer conversations, because some of its matches ring a previous owner, a tenant or a disconnected line. Ask the vendor, in writing, which definition applies to the match you are billed for. What a phone match rate means goes deeper on the gap between a reported match rate and a dialer’s result, and wireless vs landline homeowner lists covers why line type on every number matters for both connect rates and compliance.
From price per match to cost per connect
A call center does not buy matches; it buys conversations with homeowners. Translating one into the other takes three rates you can only measure by dialing your own file:
- Match rate — matched records over submitted records.
- Working-number rate — matched phones that ring through rather than return a disconnect or wrong-number disposition.
- Right-party rate — working numbers that reach the person on the record when someone picks up.
Cost per right-party contact is the append price per match divided by the working-number rate and the right-party rate. As a worked example with made-up inputs, not benchmarks: at $0.03 a match, a file where 70% of matched phones work and 60% of those reach the owner costs $0.03 ÷ 0.70 ÷ 0.60, about $0.071 per reachable right-party number. A $0.02 append where 50% work and 40% reach the owner comes to $0.10. The cheaper append is the more expensive one.
Even then, the append is rarely the biggest line. Every dead or wrong-party number also costs agent time at the dialer, which no append rate card prices. That is why the right-party rate, not the cents per match, is the number to compare — see how many dials per appointment for how the dial count compounds, and the skip tracing cost calculator to run the division on any two quotes.
When an append is the wrong product
An append assumes the name on your record is still the person who lives there. On a fresh CRM export of your own customers that is usually true. On an aged lead list, a county roll that has not caught up with recent sales, or anything bought second-hand, it often is not, and the append will faithfully attach a working phone to the wrong person. That file needs the owner resolved first, which is a skip trace — the line between the two is drawn in skip tracing vs data append, and the published trace rates are compared in best skip tracing software.
Where Scout Data fits
Scout Data is not an append service, and does not take your file in to add phones to it. It builds the homeowner audience from live property signals — storm exposure, permit activity, roof age, ownership change — resolves each parcel to its current owner of record, and ships the record with a phone matched to that owner by name, DNC-scrubbed and with dead numbers replaced. For a floor comparing it with an append, the fair test is cost per right-party contact on the same market, and homeowner phone lists for call centers covers how to run it.
Frequently asked questions
How much does a phone append cost per record?
Self-serve phone append is publicly advertised at $0.02 to $0.03 per matched record as of October 2026: DataZapp lists $0.03 per match pay-as-you-go with a $125 minimum and $0.02 with a $2,000 prepaid balance, and Tracerfy’s Normal Trace, which takes a name and address and returns phones, lists $0.02 per hit. Records that do not match are not billed at either.
What counts as a match in a phone append?
Whatever the vendor says it does, which is why it has to be asked. At the loose end, a match is any phone associated with the address. At the strict end, it is a phone linked to the exact person you supplied, with line type and recent activity attached. Both are billed at the same rate per match; only the strict one is a reliable right-party number.
Is phone append the same as skip tracing?
No. A phone append attaches a number to a person you have already identified, usually a name at an address. A skip trace starts from an address or an outdated record and first decides who the person is. An append is cheaper because it skips that step, and it is only as right as the name you gave it.
