ZoomInfo vs Lusha vs Apollo vs MillionPhones: Honest Comparison (2026)

If you're building a sales pipeline, you need phone numbers. The market is flooded with tools promising "verified direct dials" — but they vary wildly in price, accuracy, and what you actually get. Here's an honest breakdown.

Quick Comparison

ZoomInfo

ZoomInfo is the industry standard. Their database is massive, their intent data is best-in-class, and enterprise sales teams swear by it. The catch: pricing starts around $15,000/year and requires an annual contract. If you're an SDR team of 10+ at a well-funded company, it's worth it. If you're a solo founder or small team, it's overkill.

Best for: Enterprise sales teams with budget. Companies that need intent data and advanced firmographics alongside contact info.

Worst for: Startups, solo founders, anyone who just needs phone numbers without the full platform.

Lusha

Lusha made a name with their Chrome extension — hover over a LinkedIn profile and get the phone number. It's simple and it works. Their data quality for US direct dials is solid. The free tier is slim (5 credits/month), and pricing scales quickly once you need volume.

Best for: Individual reps who prospect on LinkedIn and need a quick lookup tool.

Worst for: Bulk operations. If you need to enrich a CSV of 1,000 leads, the per-credit cost adds up fast.

Apollo

Apollo is a full sales engagement platform — sequences, email tracking, dialer, and a contact database. Their strength is email addresses, not phone numbers. Phone number coverage exists but it's thinner than dedicated phone data providers. The platform tries to do everything, which means the data layer isn't as deep as specialists.

Best for: Teams that want an all-in-one outreach platform and primarily use email. The free tier is generous for email-first workflows.

Worst for: Cold callers who need reliable mobile numbers. Phone data is not Apollo's primary strength.

MillionPhones

MillionPhones focuses on one thing: verified mobile phone numbers for B2B contacts. No sequences, no email tracking, no CRM — just phone numbers. Search by LinkedIn URL, upload a CSV, or use the API. The free tier gives you 50 credits (5 phone lookups) to test data quality before paying anything.

Best for: SDRs and sales teams who cold call and need reliable mobile numbers. Teams that already have a CRM and outreach tool and just need a data source.

Worst for: Teams that need a full sales engagement platform. If you want sequences, email tracking, and a dialer in one tool, look elsewhere.

Data Quality: The Real Differentiator

Every provider claims "95%+ accuracy." The reality is messier. Phone numbers go stale fast — people change jobs, switch carriers, or port numbers. The only honest measure is: when you call the number, does someone pick up?

Here's what actually matters when evaluating data quality:

• Mobile vs. landline vs. HQ switchboard: A "direct dial" that routes to a company's front desk is useless for sales. Make sure you're getting actual mobile numbers.
• Data freshness: How often is the database updated? Numbers from 2 years ago have significantly higher disconnect rates.
• Coverage by geography: US coverage is strong across all providers. International coverage varies wildly.
• Coverage by seniority: C-suite numbers are harder to get than mid-level managers. Check coverage for the personas you actually sell to.

Which One Should You Pick?

The honest answer: it depends on your workflow and budget.

• You have enterprise budget and need everything: ZoomInfo
• You prospect on LinkedIn individually: Lusha
• You need email sequences + some phone data: Apollo
• You cold call and just need mobile numbers: MillionPhones

The best approach for most teams: start with a free tier, test 20-30 numbers against your target market, measure connect rates, then commit. Don't sign an annual contract based on a demo.
