8 Phone Number Discovery and Business-Contact Tools
The phrase “phone number scraper” covers several different products. A browser scraper can collect a number that is visibly published on an approved page. A B2B database searches a vendor-maintained contact dataset. An enrichment product fills selected fields from an existing business identity or profile. These are distinct workflows, so the right choice depends on where the contact information should come from and how it will be used.
This guide compares eight current options without fixed prices, accuracy rates, contact-count claims, or personal testing. Confirm source permissions, data-protection obligations, outreach rules, vendor terms, and your internal approval process before collecting or using contact information.
Start with the Data Source
- Visible business contact details: Use a browser-first extractor when an approved directory, company site, or listing page visibly publishes the number you need.
- B2B contact enrichment: Use a contact-data platform when a work email, name, company, CRM record, or profile URL needs business contact fields appended.
- LinkedIn-oriented prospecting: Use an enrichment or workflow product when the starting point is an existing profile identity rather than a published phone number.
- Local-business research: Use a platform workflow when location-based public business listings need to become a dataset for a permitted research process.
1. Thunderbit: Agentic Web Scraper for Visible Contact Data
Thunderbit is an agentic web scraper—an AI agent for web scraping—for turning authorized browser-visible business data into structured rows. For a permitted directory, careers page, or company site, it can help capture fields such as business name, phone number, address, website, and source URL.
The workflow is: AI Suggest Fields proposes columns; you review or adjust them; then one click on Scrape starts extraction. Results can be exported to Excel, Google Sheets, Airtable, and Notion.
For developers who need to move reviewed contact research into an approved data pipeline or agent workflow, Thunderbit also supports a Web Scraper API, MCP, and CLI.
Best for: Teams collecting already visible business contact details from approved web sources, with source URLs retained for review.

2. Apollo: B2B Contact and CRM Enrichment
Apollo provides contact and account enrichment for CRM records, CSV files, and API-connected systems. Its current product materials describe a B2B database, deduplication, scheduled enrichment, and data review before importing records into other systems.
Best for: Revenue teams that have a defined business identity and want to assess a B2B enrichment workflow alongside CRM and outreach operations.
3. Lusha: Browser-Based B2B Contact Discovery
Lusha offers a Chrome and Edge browser extension for revealing business contact details—such as emails, direct dials, and phone numbers—while a user is researching on supported pages, CRM records, or company websites.
Best for: B2B teams that want to discover or save business contact details in the context of existing account research.
4. Kaspr: LinkedIn and CSV Contact Enrichment
Kaspr supports enrichment from LinkedIn-related workflows and uploaded CSV lists. Its help documentation explains that CSV enrichment uses standard LinkedIn profile URLs and can append business contact information, including phone numbers and email addresses; the feature is currently marked beta.
Best for: Teams with a permitted LinkedIn-profile or CSV starting list that need to evaluate profile-based enrichment, rather than web-page phone extraction.
5. ZoomInfo: Enterprise Contact Intelligence
ZoomInfo is a B2B intelligence platform for account and contact research, enrichment, and go-to-market workflows. It is a category fit when procurement, CRM governance, and enterprise data operations matter as much as a single contact lookup.
Best for: Larger B2B organizations evaluating governed contact intelligence alongside their existing sales and marketing systems.
6. Apify: Cloud Data-Collection Workflows
Apify provides cloud Actors and datasets for data collection and automation. Its platform offers community and vendor-maintained components, so a team should review the maintainer, source permissions, fields, run behavior, and output schema before using a contact-data workflow.
Best for: Technical teams that want to build or assess a reusable cloud program for permitted public-business research.
7. Outscraper: Location and Business-Listing Data Workflows
Outscraper offers data-collection products for business listings and location-oriented research. It is most relevant when a team is evaluating a business-listing workflow rather than a general B2B contact database.
Best for: Location-based market research or local-business analysis where the source and permitted use have been reviewed in advance.
8. PhantomBuster: Profile-Based Prospecting Workflows
PhantomBuster provides a browser extension and workflow products for prospecting, profile data, and enrichment. Its extension can surface phone details when they are available; its enrichment materials also distinguish profile identity data from contact discovery.
Best for: Teams that have a permitted profile-based prospecting workflow and need to evaluate enrichment as one controlled stage, not as a guarantee of contact availability.

A Responsible Contact-Data Workflow
- Define the business purpose, permitted sources, fields, users, retention period, and downstream systems before collection.
- Choose visible-web extraction, B2B enrichment, or profile-based enrichment based on the actual source—not on a generic “phone scraper” label.
- Retain source URLs and collection dates for records gathered from public pages.
- Review uncertain, outdated, duplicate, or sensitive records before a CRM, report, or outreach process uses them.
- Apply the organization’s approval, suppression, access-control, and deletion processes before any outreach or sharing.
FAQs
Is a phone number scraper the same as a B2B database?
No. A web scraper collects data visible on a page. A B2B database searches the provider’s contact data. An enrichment tool appends data to an identity or existing record. These tools can serve adjacent workflows but use different data paths and controls.
Which approach fits local-business research?
Start with an approved local-business or company source and use a visible-web or location-listing workflow. Keep the source URL with the record, define the research purpose, and review availability rather than assuming every listing will publish a phone number.
Which approach fits a CRM enrichment workflow?
Apollo, Lusha, Kaspr, and ZoomInfo are contact-intelligence or enrichment options. Compare their source model, fields, integrations, review controls, and contractual terms against the organization’s data-governance requirements.
