Direct Dial Phone Numbers for Prospect Lists: 2026 Costs

Prices checked October 1, 2026. Buyers ask us for phone numbers in their own words: "direct numbers," "mobile numbers," "cell numbers," "just phone numbers." About 25 support conversations this summer were about phones, and the same four questions came up again and again. This page answers them. We make Clu, so our own figures are here with their limits, and every other vendor's price comes from our B2B data pricing index.

What is a direct dial phone number?

A direct dial phone number reaches one named person when you call it. It skips the main company line, the reception desk and the phone tree. In B2B data, "direct dial" covers two kinds of line:

• A desk line assigned to the person at work. It rings at their desk or in their softphone.
• A mobile, either a company phone or a personal mobile the person uses for work.

What it does not cover is the switchboard: the company's main number, which gets you to a receptionist or a menu. Many purchased lists fill the phone column with switchboards, which is why a list can have "phone numbers" on every row and still produce few conversations.

Direct dial, mobile or switchboard: which do you need?

Most outbound teams want a mobile first and a desk line second, so ask any vendor how many of its direct dials are mobiles before you compare coverage figures.

Where do B2B direct dials come from?

Phone data vendors commonly assemble numbers from several kinds of source: numbers people share through contributory networks and apps, public business sources such as company websites and filings, and data licensed from other vendors. Each vendor's mix is different, and so each vendor finds numbers the others miss. That is the reason waterfall enrichment exists: it asks one provider, and if that provider has no verified number, it asks the next.

Clu runs that waterfall across 25+ data providers and stops at the first verified result, inside AI agents that also find the buyers and send the sequences. The same logic is why no single vendor's coverage figure tells you what you will get on your own list.

Four questions to ask about any phone data

These are the questions our buyers asked most, and the ones worth asking every vendor, us included.

1. Is it a direct dial or a mobile, and is it labelled?

Ask what the vendor's headline phone figure counts. Clu's benchmark figure is a phone number figure: 85% phone numbers on the Clu 500-Lead Enrichment Benchmark, which is our own test on a 500-lead sample. It is not a test of any other vendor. We do not publish a mobile-only rate, so this page does not give one. If mobiles matter most to your team, run a sample of your own list and count them.

2. Is it a work number or a personal one?

A number alone cannot tell you. A mobile can be a company phone or a personal one the person uses for work. Ask the vendor how it labels each number, and check the labels on a sample before you load a dialer.

3. What happens when the number reaches the wrong person?

Every phone data set has some. Common causes are people who changed jobs, two people with the same name, and old numbers that were reassigned. A wrong number looks exactly like a found number to any billing system, so the check is to dial. Before you load a whole list into a dialer, call 20 numbers from it, log what you reach, and judge the list from that.

4. Can I buy phones only, and what does one cost?

Yes, through the Clu MCP server, which starts on the Starter plan, and the public API, which starts on Pro. Both have a phone-only mode that returns a phone number with no email lookup, at 10 credits per number found. The MCP server is open during the 14-day Pro trial, and API keys start working on a paid Pro or Enterprise plan. On a list in the app, a phone number is also 10 credits, a verified work email is 1, and both on one row is 11. A lookup that finds nothing costs nothing. Other vendors price phones per credit, per export or per reveal, which is why the next table needs care.

What direct dial phone numbers cost

Prices below are published list prices from our price ledger and pricing indexes, read between August 7 and October 1, 2026. They measure different things, so read the "How it is metered" column before comparing.

Three things matter more than the headline figure:

• When you are charged. Clu, BetterContact and Snov.io's phone search charge only when a number is found. Apollo charges credits per phone number revealed and ContactOut meters exports, so ask each how it bills a contact with no number.
• Seats. Apollo prices per user and ContactOut's self-serve plans allow one user per company, so the per-number price holds only for one person. Clu prices per seat too, but every seat's credits go into one shared pool.
• What else the price buys. Apollo's credits also pay for its sequences and dialer. ContactOut's plan includes unlimited email reveals. Clu's paid plans also include Sequences, and sending and search cost no credits.

The per-vendor detail is in our BetterContact pricing, ContactOut pricing and Snov.io pricing breakdowns.

How to add direct dials to a whole prospect list

1. Start from a file with a name and a company for each person. A first name, a last name and the company's web domain is the best combination. A work email you already hold helps too. If you only have company names, find the right people first with our guide to finding decision makers at a list of companies.
2. Upload it and add direct dials to the enrichment. A phone number is 10 credits and a work email 1, so a row that gets both is 11. For phones with no email lookup, use the phone-only mode in the MCP server (Starter and above) or the public API (Pro and above), at 10 credits a number. During the 14-day Pro trial, use the MCP server: API keys start working on a paid plan.
3. Let the waterfall run. Each row goes to one provider after another until a verified number comes back. A row with no number costs nothing.
4. Dial a sample first. Twenty calls tell you more about the list than any vendor's accuracy claim, ours included.
5. Send the list to where you call from. On Pro and above, Clu syncs to HubSpot or Salesforce, and its agents push people to Salesloft or Lemlist; on every plan you can export a CSV.

The 14-day Pro trial comes with 250 credits and 3 seats. At 10 credits a number, that is 25 phone numbers, enough to test phone coverage on a sample of your own list in the app, where a row with both an email and a phone is 11 credits. For a larger job, the credit math is simple: a Starter seat's 750 credits a month covers 75 phone numbers, and a Pro seat's 1,500 covers 150. Our guide to enriching a CSV of leads covers file preparation in detail, and the find phone numbers page shows the product side.

Before you call

Calling rules differ by country, and in the US by state, and they are stricter for mobiles, for autodialers and for text messages. Check the rules for every place on your list before you dial, and keep your own do-not-call list for anyone who asks. Our guide on how to find a phone number for someone walks through the US Do Not Call Registry and the TCPA rules on mobiles in more detail. None of this is legal advice. For the whole job, from picking accounts to keeping the numbers current, see how to build a cold calling list. To pick the dialer that will call these numbers, our cold calling software comparison lists 11 with prices and the FTC and FCC rules on automated calls.

Frequently asked questions

What is a direct dial number?

A direct dial number is a phone number that connects to one specific person without a switchboard or receptionist. In B2B data it can be a desk line or a mobile.

Is a direct dial the same as a mobile number?

Not always. Every mobile used for work is a direct dial, but a direct dial can also be a desk line. If mobiles are what you need, ask a vendor for its mobile rate on a sample of your list.

How much do direct dial phone numbers cost per contact from B2B data providers?

About $0.16 to $0.75 a number on published 2026 plans. Apollo Basic annual is about $0.16 (8 credits per number, per seat), Snov.io $0.20 to $0.44 in tokens, UpLead Essentials about $0.44 per contact with the phone included, and BetterContact $0.40 to $0.75 per mobile found. Clu (our product) is 10 credits per phone number found, about $0.49 on Starter billed annually and $0.65 monthly.

How accurate are direct dial numbers?

Every vendor's accuracy figure is its own. Clu's is 85% phone numbers on its own 500-lead benchmark sample, which is not a test of any other vendor. The reliable measure is to dial a sample of your own list.

Can I get direct dials for a whole list at once?

Yes. Upload the list with a name and company domain for each person, choose to append direct dials, and pay per number found. At 10 credits a number, one Clu Starter seat covers 75 phone numbers a month.

Is there a simple way to enrich a CSV of prospects with phone numbers and email addresses?

Yes. Put first name, last name and company domain in separate columns, upload the CSV to an enrichment tool, and ask for both fields. In Clu each row runs through a waterfall of 25+ providers: a verified work email is 1 credit, a phone number is 10, both on one row is 11, and a row with nothing found costs nothing. Download the file or, on Pro and above, sync it to HubSpot or Salesforce.

Why do so many phone numbers on a list turn out wrong?

People change jobs, numbers get reassigned, and many lists fill the phone column with the company's main line. Enriching close to the date you call, and dialing a sample first, removes most of the waste.
