ZoomInfo vs Cognism (2026): Phone Data, Regional Coverage, Credits, Contracts and Compliance Compared

By Laurel · Updated Oct 24, 2026

You're a CRO, a VP Sales or a RevOps lead, and both of these vendors are on your shortlist for the same reason: your reps need verified contacts, and they need phone numbers that connect. Neither vendor publishes a price. Both sell through a sales conversation. So the real questions are narrower than a feature list suggests. Where is your territory? How much of your outbound is phone? And what happens to your budget when the quote lands?

ZoomInfo is the larger, platform-style option. It sells editions priced by features, licenses and credit usage, and it publishes a regional breakdown of its database that leans heavily to North America. Cognism sells two plans with five seats each, leads its marketing with phone-verified mobile numbers and built-in call screening, and positions itself as "built for growth in Europe". This page compares them as data platforms and as buying decisions: verification claims, regional coverage, credit mechanics, contract terms and the compliance rules that apply when you call or email what you buy. For the wider market, start with the best sales intelligence tools hub, or the best B2B data providers comparison.

TL;DR

Key Facts

• Reps spend 40% of the workweek selling and almost one full day a week on prospecting, per Salesforce's State of Sales report, so the quality of a contact list is multiplied across every rep.
• ZoomInfo's data page lists North America as 157.8M+ contacts and 77.7M+ mobile numbers, against Europe at 66M+ contacts and 18.5M+ mobiles (vendor claim).
• Cognism says its phone-verified mobiles bring "up to 3x higher connect rates" and that Director-level and above data is refreshed on a 30-day basis (vendor claims).
• Cognism's compliance page says data is scrubbed against "15 major Do Not Call and TPS lists", while its FAQ names 12 countries (vendor claim).
• Vendr reports a median ZoomInfo contract value of $33,500 a year across 1,578 purchases (reported), with contracts running one to three years.
• The UK ICO fined a company GBP 160,000 on 20 May 2026 for over 700,000 unsolicited calls to numbers on the TPS and CTPS registers.

Who Each Platform Is Built For

ZoomInfo and Cognism overlap on the core job: a verified email or mobile number for a named buyer. They differ on where that buyer is likely to sit and what you're expected to buy around the data.

ZoomInfo is built as a platform. Its pricing page lists three sales editions (Professional, Copilot Advanced and Copilot Enterprise) and three marketing editions (Demand, ABM Lite and ABM Enterprise), and the price depends on features, number of licenses and credit usage. That shape suits a company where RevOps governs the data, marketing and sales share account lists, and intent signals feed territory planning.

Cognism is narrower. Its pricing page offers Standard and Pro, each with five seats included, and the pitch is data quality on the phone plus compliance. Pro adds higher-quality mobile data, on-demand verification and buying-intent prioritisation. CRM enrichment is sold as an add-on or on its own. That suits a sales team whose reps spend their day dialing decision-makers, especially in Europe.

Team Fit

Data Claims Compared

Both vendors make claims, and none of the numbers below is an audited count. Each defines "accuracy" its own way, so read them as marketing positions and test them on your own list.

ZoomInfo's data page claims 500M+ professional profiles, 300M+ verified business emails and 135M+ direct dial numbers, plus a 96% email deliverability rate and 87% mobile number accuracy. The same page gives the company count as both 122M+ and 100M+ in different places, which is a good reason to ask the rep which figure applies.

Cognism publishes no total contact count. Its homepage says decision-maker data is "refreshed every 30 days", its FAQ says Director-level and above data is continually refreshed on a 30-day basis, and its pricing page says it is trusted by "4000+ companies worldwide", which counts customers, not records. The comparison is therefore asymmetrical: ZoomInfo gives you big numbers to question, Cognism gives you a verification method to question.

Phone Verification: What Each Vendor Actually Says

Phone data is the reason most buyers shortlist Cognism, so it deserves its own section.

Cognism's homepage says its mobile numbers "go through additional verification layers to improve accuracy and reliability" and claims up to 3x higher connect rates, without defining the baseline. Its FAQ says it uses "proprietary data validation methodologies, which also include manual data verification" and that a research team manually verifies customers' most desired contacts. A comparison page on its own site says numbers are validated directly by its research team and that customers can request verification on demand. The pricing page puts on-demand mobile verification in the Pro plan. Its Diamond Data product, announced in a 4 October 2021 press release, is described as phone-verified data cross-checked against global DNC lists, with "Diamonds on Demand" letting customers flag the contacts most valuable to them. The press release gives no accuracy percentage.

ZoomInfo's data page gives a number instead of a method: 87% mobile number accuracy, and 135M+ direct dials. It doesn't describe how the number is measured.

So the two vendors answer different questions. Cognism tells you how it tries to get a mobile right (manual and on-demand verification). ZoomInfo tells you how often it says it's right (a percentage). Neither gives you what you actually need, which is the connect rate on your own list.

Regional Coverage: US vs EMEA vs APAC

This is where the two diverge most, and where you should be most careful about what is a fact and what is a claim.

ZoomInfo publishes a regional table on its data page. The figures are the vendor's claims, but they are specific enough to reason about. The share of contacts that have a mobile number, calculated from those claims, drops from roughly half in North America to under a third in Europe and under a fifth in Asia.

Read that table for what it is: the vendor's own count of records, not a measure of accuracy. But it does show where the weight sits. If your reps call into North America, ZoomInfo's stated mobile coverage there is large. If they call into Europe or Asia, the stated pool is a fraction of that, and you'll want to test it.

Cognism gives no breakdown. Its homepage says "Built for growth in Europe". Its FAQ refers to decision-makers in EMEA, the US and APAC, and a comparison page lists EMEA, NAM and APAC while claiming deep UK and EU coverage and strong mobile coverage across Europe, with no country-level figures. Its Do Not Call screening list also leans European: the UK, US, Australia, New Zealand, Germany, France, Ireland, Spain, Portugal, Croatia, Sweden and Belgium, per its compliance FAQ.

How to Test Data Accuracy Before You Buy

Every vendor shows its best number. The only one that decides the purchase is the one from your own list. Cognism offers a demo and a free data sample, and ZoomInfo links to a free trial of the paid platform, so you can run this without a signed contract.

1. Build a pilot list of 300 contacts you can verify independently. Use 100 from accounts you already sell to, 100 from accounts you're prospecting now and 100 from a territory you want to enter. Weight it by region: if half your outbound is US and half is EMEA, split the list that way.
2. Pull the same 300 from each vendor. Record the email, the mobile and the title each returns.
3. Verify emails with a separate checker, then send a small test from a domain you can afford to risk.
4. Dial the mobiles. Have two reps call each set at the same times of day and log whether the right person answered.
5. Count empty results. A vendor that returns nothing for a third of your list is expensive even if what it returns is clean.
6. Check call-screening flags. For the UK and EU contacts, note how each platform marks numbers on Do Not Call or TPS lists.

Credit Models Compared

Credits behave differently on the two platforms, and neither vendor prints a per-credit price.

ZoomInfo's pricing page defines a credit as "the consumption (export) of a professional or company profile". Each export costs one credit, whether it happens as a CSV or application export, through an integration, or through the ReachOut Chrome Extension. Basic credits cover standard demographic and firmographic data, while more advanced credits cover items like technographics and org charts. Add-ons such as Streaming Intent and integrations can also affect the price.

Cognism's pricing page says "1 credit = 1 revealed contact". Viewing a previously revealed contact costs nothing. Each seat includes an allocation of credits (the page doesn't state how many), more can be bought at any time, and credits work across the platform, Enrich and the API. For CRM Enrichment, a credit is used on a new record and again only when key details change, such as a job move.

The practical difference is repeat access. If your reps revisit the same accounts over a long cycle, Cognism's free re-viewing of revealed contacts matters. If you export in bulk to a CRM or sequencer, ZoomInfo's per-export meter is the thing to model. Ask each vendor for the credit count in writing and compute cost per connected conversation, not cost per credit.

Pricing and Packaging

Neither vendor prints a price. That removes the usual first step in a comparison, so this section lays out what each vendor says and what buyers report.

Reported spend is the only way to size a budget. Vendr reports a median ZoomInfo contract value of $33,500 a year, from $7,247 to $156,032, across 1,578 purchases (reported). Source: Vendr. For Cognism, the only reported figures come from a competitor's blog: roughly $15,000 platform fee plus about $1,500 per user a year on Standard, and roughly $25,000 plus about $2,500 per user a year on Pro (reported). Source: Amplemarket. Amplemarket sells a rival product and attributes the figures to several third-party sources, so treat them as a planning range and ask Cognism for a written proposal.

Don't read the table as a ranking. The ZoomInfo figure is a median across all editions and buyers, the Cognism figures are estimates for two plans, and neither is a quote for your headcount.

Contract Terms and What to Ask For

For ZoomInfo, Vendr's page gives a useful picture of how these contracts work. Terms run one to three years, multi-year commitments are described as unlocking lower annual pricing, auto-renewal clauses are common and often carry a 5 to 10% annual escalation, notice periods are typically 30 to 90 days, and seat and credit changes are often restricted. Vendr's page suggests negotiating a longer notice window and the right to adjust seats and credits annually.

For Cognism, the same competitor blog reports that annual contracts are required, that onboarding fees of about $500 to $1,500 are usually charged separately, that auto-renewals carry 60 to 90 day notice, and that minimum seat commitments apply (reported). Source: Amplemarket. Cognism's own pricing page doesn't state any of this, so confirm each point.

Whichever vendor you pick, put these questions to the rep and get answers in writing:

Compliance and Data Rights

The vendor supplies data and a compliance posture. You still send the email or place the call, so the legal duty sits with you. What differs is how much each vendor tells you about its own handling, and how much of the call-screening job it takes on.

GDPR and the EU. Cognism's compliance page says it relies on legitimate interest under Article 6.1(f), notifies business contacts of their inclusion "within GDPR timeframes", keeps data generally inside the EEA and uses standard data protection clauses for transfers elsewhere, and notifies clients of a breach no later than 72 hours after it occurs. ZoomInfo's data page shows GDPR Compliant and CCPA Compliant badges and TRUSTe certification. A badge tells you the vendor has a program. It doesn't give you a lawful basis for your campaign.

A fine worth knowing about. Kaspr is a separate Cognism-owned product, not Cognism itself, and the ruling was not about Cognism. Cognism acquired Kaspr in 2022, for an undisclosed sum. The French regulator then fined Kaspr EUR 240,000 in a decision dated 5 December 2024, published by the EDPB on 23 January 2025, for collecting contact details through a Chrome extension from LinkedIn and other sources into a database of about 160 million contacts, citing Articles 5(1)(e), 6, 12, 14 and 15. The lesson isn't about either vendor. It's that source and transparency decide enforcement, so ask any vendor where its contacts come from and how it informs the people in its database.

CCPA and US state laws. Cognism says it is registered as a data broker with the California Attorney General and offers an opt-out form for sale of data. ZoomInfo shows a CCPA badge. Neither removes your own duties, and California's Attorney General notes that the exemptions for business-to-business transaction data expired on 31 December 2022, so B2B contact data isn't exempt by default.

PDPA in Southeast Asia. Singapore, Malaysia and Thailand each run their own data protection law with consent and notice rules that differ from the GDPR model. Neither vendor's compliance material gives a country-by-country PDPA statement. Ask each how it sources and flags contacts in the countries you target, and read the local regulator's guidance, such as the Singapore PDPC, before dialing.

Phone data and Do Not Call. This is where mistakes get expensive and where the two vendors differ most. Cognism says it matches phone numbers against Do Not Call registries and marks matches in the platform, scrubbing against lists in the US, Australia, the UK (TPS and CTPS), France, Germany and other European countries. ZoomInfo's data page doesn't mention call screening, so assume you need a separate step and ask the rep.

The rules themselves point in different directions by country. The FTC says most business-to-business calls are exempt from the Telemarketing Sales Rule, and that includes the National Do Not Call Registry provisions. Calls and texts to cell phones can still bring a private claim under the TCPA, which allows $500 in damages for each violation, trebled for willful or knowing violations. In the UK, the ICO fined Energy Prices Direct Limited GBP 160,000 for over 700,000 unsolicited sales calls between January 2024 and January 2025 to numbers on the TPS and CTPS registers. The US exemption and the UK rule pull in opposite directions, which is why a team calling both markets needs screening that covers both.

One inconsistency to raise with Cognism: its compliance page says "15 major Do Not Call and TPS lists", while its FAQ names 12 countries (13 registries if you count the UK's two lists separately). Ask for the exact list in writing before you rely on it.

Integrations and Workflow Fit

ZoomInfo is closest to a data and orchestration layer. It feeds your CRM, your marketing automation and your sequencing tool, and its credit rules mean integrations need planning rather than a casual click. Its editions add Copilot on the sales side and Demand and ABM options on the marketing side.

Cognism is closest to a prospecting tool with a compliance backbone. Its API and Enrich credits are shared with the platform, CRM Enrichment is sold separately, and intent data comes from Bombora's Company Surge topics on the Pro plan.

Implementation and Time to Value

If your company needs a vendor security review first, both vendors list SOC 2 Type II, ISO 27001 and ISO 27701, which should speed the questionnaire.

When ZoomInfo Is the Right Call

Your outbound is weighted to North America. The vendor's own regional table puts 157.8M+ contacts and 77.7M+ mobiles in North America, the largest block it shows. If most of your calls land in the US and Canada, that is where its stated depth sits.

Sales and marketing share one data layer. The Demand, ABM Lite and ABM Enterprise editions put the same data behind account-based campaigns. A team that wants one source of truth for both functions gets more from a platform built that way.

You want breadth, not just mobiles. Technographics, org charts and intent topics are part of the credit design. If your motion needs account intelligence as well as contact data, ZoomInfo's scope is wider.

You want a free look first. ZoomInfo links to a free trial of the paid platform, which makes a pilot easier than a demo-only process. If cost is the sticking point, the best ZoomInfo alternatives page covers the field.

When Cognism Is the Right Call

Your outbound is weighted to Europe. Cognism's positioning, its research teams and its call-screening list all lean European. For reps dialing into the UK, Germany, France and neighboring markets, that focus is what you're paying for.

You dial mobiles and need screening built in. Cognism says it matches numbers against Do Not Call and TPS registries and flags matches in the platform. If you'd otherwise buy a separate screening service, that bundled step has real value.

You want verification on demand. The Pro plan includes on-demand mobile verification, so reps can send priority prospects to Cognism's research team. That suits a team working a short list of named accounts.

You re-open the same accounts a lot. Viewing a previously revealed contact is free, which is a better fit for long, multi-threaded cycles. If you're weighing Cognism against other options, see the best Cognism alternatives page.

Not the Right Fit for Either

If you're a small team that wants published prices, a free plan and sequencing in one tool, neither is the natural fit. Compare Apollo vs ZoomInfo for that route, or Lusha vs Apollo if phone data on a small budget is the deciding factor. If you mainly need enrichment on an existing list, the best data enrichment tools page is a better start. And if you're still choosing a category before a vendor, the guide on how to choose sales intelligence software sets out the questions to ask first.

Decision Framework

Frame it as a question about your own territory: how many of your best-fit contacts does each vendor return with a working mobile, how many of those calls reach the right person, and what does a connected conversation cost you at your real volume. If the answers are close, pick the vendor with the easier exit.

What to Do Next

Build the 300-contact pilot list this week, split by the regions you actually call. Ask Cognism for its free data sample, ask ZoomInfo for a trial of the paid platform, and pull the same contacts from each. Dial the mobiles, verify the emails with a separate checker and log the connect rate by region. Take the cost per connected conversation to both quote conversations and use it to push on price, credit counts and renewal terms. If neither wins clearly, widen the field with the best sales intelligence tools hub before you commit.
