FullContact Pricing: Worth It or Consider ZoomInfo? March 2026

Only one of FullContact's four products (Acumen) publishes its prices. The other three (Resolve, Enrich, and Identity Streme) require a sales conversation. If you've tried to compare identity resolution platforms, you know how frustrating that split can be.

FullContact is a privacy-focused identity resolution platform. It maintains a person-centered identity graph that maps 248 million U.S. consumer profiles across 50+ billion identifiers.

The platform helps businesses recognize anonymous website visitors, unify fragmented customer records, and enrich profiles with consumer-level data.

But as a Ziff Davis subsidiary focused on identity resolution infrastructure, FullContact's pricing creates two buyer experiences: transparent tiers for lead identification, and opaque negotiations for everything else.

We've analyzed FullContact's published tiers, contract terms, and feature restrictions. It's the right choice if:

• You need consumer-level identity resolution focused on U.S. audiences

• Your primary use case is recognizing anonymous website visitors at the individual level

• You're a MarTech or AdTech platform embedding identity resolution into your own product

• You value privacy-first architecture with no data commingling between clients

• You have the technical resources to integrate via API into your existing stack

FullContact's pricing might not be a good choice if:

• You need B2B contact data with direct-dial phone numbers and verified business emails

• You want buyer intent signals that show when companies are actively researching solutions

• Your sales team needs prospecting tools, not just identity resolution infrastructure

• You require campaign execution, outreach automation, or CRM-integrated workflows

• You need a platform that works globally, not just in the United States

In this case, consider ZoomInfo: an AI GTM platform that goes beyond identity resolution to provide B2B data (500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses), buyer intent signals, AI-powered prospecting, and multi-channel execution tools.

We've included a detailed pricing comparison with ZoomInfo in this review for B2B teams needing actionable intelligence rather than identity infrastructure.

FullContact Pricing Summary

FullContact Pricing: In-Depth Overview

FullContact runs a split pricing model: Acumen (lead identification) is the only product with published prices.

Resolve (identity resolution), Enrich (data enrichment), and Identity Streme (first-party data management) all require direct sales contact.

For API and enrichment products, billing is match-based: FullContact charges only when it returns data (a "200 Response"), so queries that return no match cost nothing. All Acumen paid plans require a 12-month subscription billed monthly.

Here's what each product and tier costs.

FullContact Free Tier: 1,000 API Matches (One-Time)

FullContact offers two free entry points. Anyone can sign up for a free API key with 1,000 matches at no cost, but this is a one-time allocation, not a recurring plan.

Separately, Acumen provides a 14-day free trial with full functionality and no credit card required. Neither option gives you ongoing free access.

👉 The Bottom Line: The free options work for initial testing, but there's no way to use FullContact at zero cost beyond the trial period, unlike competitors offering permanent free tiers.

FullContact Acumen Essentials: $99/month

Acumen Essentials targets small teams testing website visitor identification.

At $99/month with a 12-month commitment ($1,188/year), it delivers 150 identified leads per month with professional email addresses and LinkedIn profile matching.

The plan includes unlimited lead report access, Slack notifications, and API access. But 150 leads per month works out to roughly $0.66 per identified visitor, and the 14-day browsing analytics window limits historical analysis.

👉 The Bottom Line: Essentials offers a limited test of FullContact's visitor identification, but 150 monthly leads and no phone numbers restrict practical sales use.

FullContact Acumen Core: $300/month

Core costs 3x more than Essentials but delivers 3.3x the leads and extends browsing analytics from 14 to 90 days.

Phone numbers and unlimited hashed emails for digital advertising make this the first tier suitable for sales teams and ad retargeting. At $0.60 per identified lead, unit economics improve slightly.

Support for up to 5 domains accommodates multi-brand businesses.

👉 The Bottom Line: Core suits growing teams that need phone numbers and multi-domain support, but the annual commitment and 500-lead cap create pressure for high-traffic sites.

FullContact Acumen Plus: Contact Sales

Plus drops the published pricing and enters sales-negotiated territory. It adds priority support, SOC2 Type 2 compliance reports, unlimited domains, and custom lead volumes.

Enterprise buyers who need compliance documentation or run dozens of web properties have no other option. But the lack of published pricing makes budgeting impossible without a sales conversation.

👉 The Bottom Line: Plus is necessary for enterprise compliance, but opaque pricing adds friction for procurement teams comparing vendors.

FullContact Resolve, Enrich, and Identity Streme: Contact Sales

FullContact's three core infrastructure products have no public pricing.

Resolve unifies customer identifiers into a single PersonID with an average match rate of 93%. Enrich appends consumer-level data across 14 modular Insights Bundles. Identity Streme provides encrypted first-party data storage with PII deleted at ingestion.

All three use match-based billing (you pay only for successful results), but the per-match cost remains undisclosed.

👉 The Bottom Line: These products serve real enterprise needs, but the complete lack of pricing transparency makes comparison shopping nearly impossible without a sales conversation.

FullContact Contract Terms and Hidden Costs

Beyond subscription fees, FullContact's Services Agreement reveals several cost considerations:

• Contract Rigidity:

• All Acumen paid plans require 12-month subscriptions billed monthly

• Payment obligations are non-cancelable and fees paid are non-refundable

• Contracts automatically renew unless you provide 30 days written notice before renewal

• Additional Fees:

• All applicable taxes are borne by the customer

• 1.5% per month late payment fee on overdue balances

• Invoices due within 15 days

• FullContact may accelerate future invoicing to match consumption

• Data Retention Restrictions:

• Customers can retain FullContact data only while actively paying

• All FullContact data must be irrevocably deleted within 30 days of termination

• Compliance records must be maintained for 3 years post-termination

Where FullContact Falls Short

FullContact provides identity resolution infrastructure for consumer data. But its narrow focus and pricing opacity create real challenges for B2B revenue teams:

• U.S.-Only Coverage Creates a Hard Ceiling

• FullContact does not do business with companies looking for identity resolution outside of the United States

• The 3X recognition guarantee applies only to U.S.-based people

• Any buyer with international customers, prospects, or operations hits an immediate wall

• No B2B Prospecting or Sales Execution Tools

• FullContact is a data infrastructure layer with no outbound engagement, CRM, or activation capabilities

• The platform does not sell lists or audiences for marketing purposes

• Sales teams cannot prospect, build lists, or run outreach sequences within the platform

• Every action requires a separate tool

• Pricing Opacity for Core Products

• Three of four products (Resolve, Enrich, Identity Streme) have no public pricing

• Only Acumen publishes its tiers, and even those require 12-month commitments

• Mid-market buyers cannot benchmark costs without engaging sales

• Non-cancelable contracts and mandatory data deletion upon termination add risk

• No Buyer Intent or Signals Intelligence

• FullContact identifies who visitors are but not why they're visiting or what they're researching

• No intent data to prioritize accounts showing buying signals

• No technographic or funding-event signals

• Teams receive identity data without the context needed to act on it

These limitations have led many B2B teams to explore platforms that combine identity data with intelligence and execution tools in one place.

Best FullContact Alternative - ZoomInfo

ZoomInfo is an AI GTM platform built on a B2B data foundation of 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses.

Its GTM Context Graph, which processes 1.5B+ data points daily, unifies this data with your CRM records, conversation transcripts, and behavioral signals to show not just who your prospects are, but why they're in-market and what to do next.

Source: ZoomInfo

For buyers who find FullContact's U.S.-only coverage limiting, its pricing opaque, and its lack of prospecting and intent capabilities constraining, ZoomInfo offers a broader solution that carries intelligence through the entire revenue cycle, from identifying accounts to closing deals.

That intelligence is accessible through three channels: GTM Workspace for sellers, GTM Studio for marketers and RevOps, and APIs and MCP for custom tools or AI agents.

ZoomInfo Lite: $0/Month (Permanent Free Tier)

Unlike FullContact's one-time 1,000-match allocation, ZoomInfo Lite is a permanent free tier with monthly credits that refresh.

You get access to ZoomInfo's B2B database with advanced search filters, CRM data enrichment, HubSpot integration, and real-time data updates.

For small teams evaluating platforms, Lite provides ongoing value without requiring a credit card.

👉 The Bottom Line: ZoomInfo Lite gives teams more ongoing value than FullContact's one-time free allocation: permanent access to B2B data with refreshing credits.

ZoomInfo Sales Professional: Custom Pricing

Sales Professional provides the core prospecting experience: access to ZoomInfo's full database with 120M direct-dial phone numbers and 200M+ verified business emails at up to 95% accuracy.

Territory management filters, prospect lists with alerts, and CRM integrations make this an operational tool, not just a data source. AI-powered email generation drafts personalized outreach from account context.

👉 The Bottom Line: Sales Professional delivers the verified B2B contact data and prospecting tools that FullContact's infrastructure layer does not provide.

ZoomInfo Sales Advanced: Custom Pricing

Advanced adds the intelligence layer that separates a data platform from a revenue platform.

Buyer Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings sourced monthly. Guided Intent, exclusive to ZoomInfo, identifies topics historically correlated with closed deals rather than requiring manual topic selection.

Website visitor tracking resolves anonymous traffic to companies with buying team identification.

👉 The Bottom Line: Advanced turns ZoomInfo from a data provider into an intelligence platform, with intent signals and AI capabilities FullContact does not offer at any tier.

ZoomInfo Sales Enterprise: Custom Pricing

Enterprise provides ZoomInfo's GTM Context Graph at full scale: real-time buyer intent signals, sales activity automation, AI-generated account summaries, and custom integrations.

A dedicated customer success manager and white-glove onboarding support enterprise deployment. GTM Workspace puts AI agents to work on account research, outreach drafting, and CRM updates.

👉 The Bottom Line: Enterprise delivers AI-powered GTM intelligence that makes ZoomInfo an execution platform, not just a database.

FullContact Feature Value Breakdown (vs. ZoomInfo)

Data Coverage and Scope

FullContact's Approach: FullContact maintains a person-centered identity graph with 248 million U.S. consumer profiles and 900+ data attributes.

The enrichment data skews toward consumer attributes: household composition, net worth, interests, purchase behavior, and social profiles.

Coverage is limited to U.S. adults, and the company does not provide identity resolution outside the United States.

ZoomInfo's Approach: ZoomInfo operates a B2B data platform covering 500M+ contacts, 100M+ companies, 135M+ verified phone numbers, 120M+ direct-dial phone numbers, and 200M+ verified business email addresses.

Source: ZoomInfo

Global coverage includes 34M+ company profiles outside North America, 200M+ professional profiles outside NA, and 45M+ mobile numbers outside NA.

Verification runs through a multi-source pipeline backed by 300+ human researchers achieving up to 95% accuracy on first-party data.

🪙 Value Verdict: ZoomInfo is better for B2B teams needing verified business contact data at global scale. FullContact serves a narrower use case: U.S. consumer identity resolution.

Intelligence and Signals

FullContact's Approach: FullContact identifies website visitors through its identity graph, using deterministic resolution based on real observations rather than IP-only lookup. The typical Acumen customer recognizes 45–70% of website visitors.

Source: FullContact

But the data returned is identity only: name, email, employer, title, LinkedIn URL. No intent signals, no buying behavior indicators, no information about what the visitor is researching or how ready they are to buy.

ZoomInfo's Approach: ZoomInfo layers identity with intelligence.

Buyer Intent tracks signals from 210 million IP-to-Organization pairings and 6 trillion+ keyword-to-device pairings sourced monthly.

Source: ZoomInfo

Guided Intent identifies topics historically correlated with deal success.

WebSights resolves anonymous website traffic to companies with buying team identification and automatic traffic filtering that separates real visitors from bots.

Source: ZoomInfo

The GTM Context Graph fuses all of this with CRM records, conversation transcripts, and behavioral signals to reveal why prospects are in-market, not just that they visited.

🪙 Value Verdict: ZoomInfo is better for teams that need to prioritize and act on leads, not just identify them. Knowing a visitor's name matters less than knowing they're actively researching your category.

Execution and Activation

FullContact's Approach: FullContact is an infrastructure layer. It does not sell lists or audiences for marketing purposes, and will not provide PII that the organization doesn't already have.

There is no outreach, sequencing, campaign execution, or CRM built into the platform. Customers must export resolved PersonIDs and enriched data to separate tools for any action.

Every lead identified by Acumen or resolved by Resolve requires a handoff to another system before a sales rep can act on it.

ZoomInfo's Approach: ZoomInfo connects intelligence to action.

GTM Workspace gives sellers a single place where prioritized accounts, AI-drafted outreach, and deal execution converge.

Source: ZoomInfo

GTM Studio lets marketers and RevOps design, enrich, and activate GTM plays in natural language. Automated workflows trigger outreach when signals fire.

Source: ZoomInfo

Native integrations with Salesforce, HubSpot, and Microsoft Dynamics keep CRM data current without manual work.

For teams building custom tools, APIs and MCP deliver the same intelligence to any third-party application.

Source: ZoomInfo

🪙 Value Verdict: ZoomInfo is better for revenue teams that need to act on data, not just receive it. The gap between identifying a visitor and closing a deal requires tools FullContact does not provide.

Pricing Model and Transparency

FullContact's Approach: FullContact's pricing is split: Acumen publishes three tiers ($99, $300, and contact-sales), while Resolve, Enrich, and Identity Streme have no public pricing.

Acumen plans require 12-month commitments with non-cancelable, non-refundable terms.

The match-based billing model (pay only for successful results) sounds appealing, but without published per-match rates for enterprise products, buyers cannot estimate costs before engaging sales.

Data must be deleted within 30 days of contract termination.

ZoomInfo's Approach: ZoomInfo also uses custom-quoted pricing based on seats, credits, and features.

But ZoomInfo provides two free entry points: ZoomInfo Lite ($0/month, permanent) and a 7-day free trial.

Source: ZoomInfo

The credit system is straightforward: 1 credit = 1 export, and searching or viewing data does not consume credits. API access is included in all relevant plans, and ZoomInfo is moving toward consumption-based pricing that aligns cost with usage.

🪙 Value Verdict: Neither platform publishes dollar amounts for core enterprise products. But ZoomInfo's permanent free tier, clear credit mechanics, and broader feature set at each paid tier give B2B teams more entry points and more value per dollar.

Final Verdict: FullContact vs. ZoomInfo

The choice between FullContact and ZoomInfo depends on whether you need identity infrastructure or a complete revenue platform.

FullContact is a privacy-first identity resolution platform designed for MarTech and AdTech companies that need to unify fragmented consumer identifiers into a persistent person-level view.

With Acumen pricing from $99–$300/month for lead identification and sales-negotiated pricing for Resolve, Enrich, and Identity Streme, it helps platforms and brands recognize U.S. website visitors, enrich customer profiles with 900+ consumer attributes, and manage first-party data in a privacy-compliant encrypted environment.

This approach works best for companies embedding identity resolution into their own products, enterprise brands with large U.S. consumer databases needing unification, and technical teams comfortable integrating via API into existing MarTech stacks.

ZoomInfo is an AI GTM platform built on B2B data covering 500M contacts, 100M companies, 135M+ verified phone numbers, and 200M+ verified business email addresses.

By fusing this data with your CRM records, conversation intelligence, and behavioral signals through the GTM Context Graph, ZoomInfo goes beyond identifying who your prospects are to revealing why they're in-market and what to do next.

That intelligence reaches your team through GTM Workspace for sellers, GTM Studio for marketers and RevOps, or APIs and MCP in any tool.

This makes it essential for B2B revenue teams that need verified contact data and direct dials, buyer intent signals to prioritize accounts showing purchase intent, and AI-powered execution tools that turn intelligence into pipeline.

The difference is scope. FullContact answers "Who is this person?" ZoomInfo answers "Who should we sell to, why are they ready now, and what should we say?"
