ListGiant is a list broker in the classic shape: a large master file, several hundred selects, a portal for counts, a quote form for the price. It ranks for homeowner phone lists and telemarketing lists, it is a registered data broker, and it sells the same rows into email, direct mail, social audiences and the dialer. What it does not do, on any page we could read, is print a price. So the two things a call center can actually evaluate before the quote arrives are the record — where a row comes from and what it is keyed on — and the guarantee, which is written in a way that rewards a careful reading.
Disclosure: Scout Data is our product and we sell homeowner phone files to call centers — treat that entry as a maker’s pitch and the rest as our honest read of ListGiant’s public pages, quoted as advertised on 19 September 2026. We did not ask the vendor anything, and we did not sign up for the portal trial.

A guarantee paid out in rows
Most vendors in this category promise nothing in writing. ListGiant promises something, and the something is worth reading twice: “up to 95%” accuracy, and if the list falls short, “additional data until it meets your expectations.” It is a make-good, and the currency of the make-good is more of the product.
Take the ceiling at face value and put it on a floor’s numbers. A 25,000-row order at exactly 95% carries 1,250 rows the vendor’s own standard would call wrong. On the one file we can show dialed to exhaustion — a 25,000-record homeowner file a Bay Area solar floor ran three passes on in two days, 64,312 dials in all — each record cost about two and a half dials before the floor was through with it. At that rate the 1,250 rows cost roughly 3,200 dials, plus the agent minutes and dispositions attached, before anyone could say which rows they were. The replacement rows arrive after that spend, and they come from the same file at the same rate.
That is not an argument that the guarantee is worthless. For a mailer it is a fair trade: a bad address costs a stamp, and a replacement address is a full remedy. It is an argument that “accuracy” has to be pinned to a definition before the number means anything to a dialer. Accurate name at the address, deliverable email, and phone that rings the person named are three different measures with three different pass rates, and the pages do not say which one 95% refers to. The floor number we track is agent-tagged wrong or dead numbers per call — 3.45% of 2,205 tagged calls on that same Bay Area file — and it is a different measure again, which is the point: ask the vendor to state theirs on the quote.
Property selects on a consumer file
ListGiant is not a demographics-only broker. Its portal names a Real Property database beside Consumer Plus and Mortgage Plus, and its telemarketing selects include sale date, year built, estimated value, length of residence, loan-to-value and absentee ownership. On a count screen that looks like the same product a property-record vendor sells. The difference is underneath the selects, in what the row is keyed on.
A compiled consumer record is a person at an address. Everything else — the homeowner flag, the year built, the mortgage band, the phone — was appended to that key from other sources, and “multi sourced master file” is the honest description of how. The phone in particular is a number associated with that name or that address, and the page does not say how the wireless flag is derived. A property-record file starts on the other side: the parcel is the key, the deed names the owner, the phone is matched by name to that owner and checked live, and homes that do not produce a match are left out rather than filled. On an 18,309-parcel Texas pool we measured on 18 August 2026, 79.7% of homes produced a contact whose name matched the deed and 54.6% produced that owner with a live mobile. The rest were dropped. A compiled file, by construction, ships a row for the rest as well — and those are the rows the guarantee is about. The two record types are laid side by side in telemarketing lists for home services, and the field-by-field version is in homeowner data fields explained.
“DNC compliant” is a flag; the 31 days are yours
The portal page says the telemarketing lists “are Do Not Call (DNC) compliant.” That is the standard claim and it is true in the only sense it can be: a registry flag was applied when the slice was built. The registry itself changes every day, and the Telemarketing Sales Rule’s safe harbor turns on your having accessed it within 31 days of the call. A flag set on the vendor’s schedule cannot carry that for you. Treat it as a first pass that lowers your scrub bill, scrub inside the window yourself, and load nothing that has not also been run against your own suppression file. The routine is in DNC compliance for outbound solar and building a suppression list; none of it is legal advice.
One line on the same page deserves credit: ListGiant will suppress previously purchased lists and your customer database against a new order. Ask for that on every reorder, in writing, and ask which prior orders it covers — the point of a suppression is the floor never dials the same wrong row twice under two invoices.
The quote form is the price list — what to put on it
Because the price arrives by reply, the request is where you set the terms. Seven lines, all of which a broker can answer and most of which the reply will not volunteer:
- Price per record at your select count and volume, and the minimum order.
- The refresh date of the slice you would receive — not the master file’s cadence, the date these rows were last updated.
- How the wireless flag is derived, and what share of the rows carry a wireless number rather than a landline. The dialer day runs on this line; wireless vs landline homeowner lists explains why and how to verify a vendor’s flag on a hundred rows.
- The date of the DNC flag on the slice.
- What “accuracy” is measured as for the guarantee, and how a claim is filed.
- Whether prior orders and your customer file will be suppressed, and at what cost.
- Whether the homeowner flag is read from a deed or modeled from tenure and mail history. On a compiled file it is usually the second, which is why a “homeowner” select can carry renters and last year’s sellers.
Then run the sample. ListGiant offers a free one and a fourteen-day portal trial; the way to use either is to dial it, not to look at it. Free lead samples: how to test a vendor is the protocol, and what a phone match rate means is the script for getting any vendor to say which count its accuracy figure reports.
Where ListGiant is the right buy
- A multi-channel program from one file. ListGiant’s catalogue is built to push the same rows to email deployment, direct mail and social or search audiences as well as the phone. A home-services marketer running all four from one selection has a reason to buy them from one broker.
- Counts before commitment. A portal that runs real-time counts against a 280-million-row file, on a free trial, is a cheap way to size a market by ZIP before any floor buys a built file for it.
- Suppression as a service. If your ops team does not keep a clean suppression file, a vendor that will net out prior orders and your customer database for you is doing a job worth paying for.
Alternatives, by what you actually need
- The same compiled shape with the price printed. TelephoneLists.biz alternatives reads a broker that publishes its plans, its refresh cadence and its accuracy estimate on the page; DataZapp alternatives reads the compiler that prices per match. Neither answers the key-of-the-record question either, but you can do the arithmetic before the call.
- Access rather than rows. If a rep wants to look up prospects one at a time and export a few hundred a month, a subscription database is the cheaper shape — Salesgenie alternatives covers the one most people compare, and why the shape stops working when the buyer is a dialer.
- A file built for a pitch about the house. Owner on title, a sourced wireless flag, a dated scrub and the permit dates the opener needs — the category Scout Data sells into, by vertical, in roofing call center leads and solar call center leads.
Whichever way you go, keep the discipline ListGiant’s guarantee invites: decide what a wrong row costs your floor before you decide what a replacement row is worth. On a dialer the first number is always larger.

Frequently asked questions
How much does ListGiant charge per record?
It does not say. None of the ListGiant pages we read on 19 September 2026 — the home page, the homeowner and renter list, the new homeowners list, the telemarketing lists page, the roofing page, the list portal — prints a per-record price, a minimum, or a plan. Each ends in a quote form that promises a reply within thirty minutes on weekdays, and the portal offers a fourteen-day free trial without a card. The price is whatever comes back on the quote, which is why this page is about the guarantee and the record rather than the sticker.
What does ListGiant’s 95% accuracy guarantee actually cover?
The wording is “up to 95%,” and the remedy is “additional data until it meets your expectations.” Two things follow. “Up to” is a ceiling, not a floor, and the page does not define what is being measured — a name at an address, a deliverable email, or a phone that rings the person named. And the make-good is more rows, not money back. For a mailer that is a fair trade. For a dialer floor the cost of a wrong row is the dials it took to find out, and no replacement row refunds those.
Are ListGiant’s telemarketing lists DNC scrubbed?
The portal page says its telemarketing lists “are Do Not Call (DNC) compliant.” Read that as a flag applied when the slice was cut. The registry changes daily — the FTC counted about 258.5 million active registrations at 30 September 2025 — and the Telemarketing Sales Rule’s safe harbor turns on your having accessed the registry within 31 days of the call. No vendor’s flag can carry that for you. Scrub inside the window, and run your own suppression file on top.
ListGiant has a Real Property database — is that a property-record file?
It has property selects: sale date, year built, estimated value, length of residence, mortgage amount. That is not the same thing as a file keyed on the parcel. On a compiled consumer file the key is a person at an address and the property fields are appended to the household; the phone is a number associated with that name or that address. On a property-record file the deed names the owner, the phone is matched to that name and checked live, and homes that fail the match are dropped. The selects look alike on a count screen and produce different dialer days.
