Best AI Tools for Phone Number Scraping and Enrichment: Apollo vs Clay vs PhantomBuster vs Apify (2026)
Amir Arsalan Sharifi
TL;DR — Quick Summary
- Apollo (270M+ contacts, ~90% accuracy) is best for B2B volume. Clay (75+ data sources, >90% enrichment accuracy) is best for finding personal mobile numbers Apollo misses. Use both.
- PhantomBuster extracts structured data from LinkedIn and social media. Apify scrapes Google Maps for local UAE business phone numbers. Neither is a primary enrichment tool.
- For UAE-focused campaigns, the best pipeline: LinkedIn outreach (PEESHEE agent) → Clay enrichment → Meta upload. Google Maps via Apify is best for local B2C targeting.
- Apollo is 65% more expensive per contact than Clay at scale. Clay's waterfall enrichment covers gaps Apollo misses — especially personal mobile numbers.
Best AI Tools for Phone Number Scraping and Enrichment: Apollo vs Clay vs PhantomBuster vs Apify (2026)
The quality of your Meta custom audience campaign starts before you open Ads Manager. It starts with how you sourced the phone numbers in the first place. A list built from Apollo's verified B2B database with Clay enrichment and personal mobile appending will match at 45–60% on Meta. A list scraped carelessly from an unrelated source might match at 8%.
This guide compares the four tools that actually get used in real agentic lead gen pipelines — Apollo, Clay, PhantomBuster, and Apify — covering what each one does well, what it cannot do, pricing, and exactly where each one fits in the pipeline to Meta.
- Apollo — B2B contact discovery at scale. Use as the first sourcing layer.
- Clay — Data enrichment and personal mobile appending. Use after Apollo.
- PhantomBuster — LinkedIn + social automation for structured contact extraction.
- Apify — Google Maps scraping for local B2C phone numbers in UAE and GCC.
Apollo.io — Best for B2B Contact Volume
Apollo.io
Apollo's proprietary database covers 270–280 million contacts across 60+ million companies. It is the largest single-source B2B database available at this price point. For UAE-focused campaigns targeting business owners, marketing managers, or C-suite at companies in specific industries, Apollo's geographic and firmographic filters let you build a targeted export in minutes.
Phone numbers are available on paid plans. Business direct lines and personal mobile numbers are both included where Apollo holds the data, but coverage varies by region. US and Western European contacts have more complete phone data than MENA markets — for UAE-specific campaigns, expect 40–60% of exported contacts to have a usable phone number, with many being office lines rather than personal mobiles.
Apollo's Strengths
- 270M+ contact database — the largest proprietary B2B source at this price tier
- ~90–91% overall data accuracy, verified by multiple G2 reviewer benchmarks
- Built-in email sequencing, dialer, and CRM integrations — all-in-one for sales teams
- Free tier includes 10,000 email credits/month — usable for initial testing
- Native export to CSV for pipeline input
Apollo's Limitations for Meta Pipelines
- Single-database source — gaps in coverage cannot be filled within Apollo itself
- MENA mobile number coverage is incomplete compared to US/EU contacts
- Business landlines rather than personal mobiles for many records — low Meta match rate without enrichment
- At large scale ($3,725/month for 40k contacts/month), costs compound quickly
Clay — Best for Enrichment and Personal Mobile Appending
Clay
Clay does not have its own database. What it has is a waterfall enrichment engine that queries 75–150+ data providers simultaneously for each contact record. You feed it a partial record — name + company, LinkedIn URL, or email — and it returns the most complete data it can find across all its sources. For personal mobile numbers specifically, Clay's multi-source approach finds data that no single provider holds.
At scale, Clay is 65% cheaper per contact than Apollo ($0.02 vs $0.093/contact). The tradeoff is setup complexity — Clay requires more technical thinking than Apollo's ready-made database interface. For an agentic pipeline, this tradeoff is worth it: once the n8n → Clay enrichment step is built, it runs automatically without human configuration.
Clay's Strengths
- 75–150+ data sources queried per record — highest coverage of any single enrichment tool
- >90% enrichment accuracy via waterfall (best-available source wins per field)
- Personal mobile number appending — finds what single-source tools miss
- 65% cheaper per contact than Apollo at equivalent scale
- Claygent AI agent for custom web scraping and unstructured data extraction
- Direct n8n integration via HTTP Request node (Clay API)
Clay's Limitations
- No proprietary database — requires contact records as input (works alongside Apollo, not instead of it)
- Steeper setup curve than Apollo for non-technical users
- Free tier limited to 100 credits/month — insufficient for production volume
- Per-enrichment credit costs can compound for high-field enrichment per record
PhantomBuster — Best for LinkedIn and Social Data Extraction
PhantomBuster
PhantomBuster automates browser-level interactions with social platforms and exports structured data as JSON or CSV. For LinkedIn, it can extract profile data from Sales Navigator searches, connection lists, or group members — including name, job title, company, email (where visible), and LinkedIn URL. These records then feed into Clay for enrichment and mobile number appending.
Phone numbers are rarely directly visible on LinkedIn profiles — most users do not display their mobile publicly. PhantomBuster's value in this pipeline is not phone number extraction directly; it is LinkedIn profile structuring that enables Clay's enrichment to find personal mobile data that is otherwise inaccessible.
PhantomBuster's Strengths
- LinkedIn Sales Navigator export automation — bypasses manual copy/paste
- Facebook Group member extraction for B2C community targeting
- Instagram follower/following export for social audience building
- Structured JSON output — directly usable in n8n via HTTP node
- Pre-built "Phantoms" for 20+ platforms — no custom scraping code required
PhantomBuster's Limitations
- LinkedIn rate limits — must run slowly to avoid account flag (daily limits apply)
- Phone numbers rarely directly available — tool is for structured profile data, not raw phone extraction
- Requires an active LinkedIn account with Sales Navigator for best results
- Platform terms of service must be followed — aggressive scraping can result in LinkedIn account restrictions
Apify — Best for Google Maps and Local UAE Business Phone Numbers
Apify
Apify is a cloud web scraping platform with pre-built "Actors" (scrapers) for dozens of sources. The Google Maps Scraper Actor extracts business name, phone number, address, category, rating, review count, and website from any geographic area and business category search. For B2C campaigns targeting UAE consumers through their local businesses — restaurant owners, clinic patients, gym members — Google Maps is one of the richest publicly available phone number sources.
Output is structured JSON, directly n8n-compatible. A single Apify Google Maps run covering "restaurants in Dubai Marina" returns hundreds of phone-verified business listings within minutes. For local service businesses targeting other businesses in a specific area, this is the fastest sourcing path.
Apify's Strengths
- Google Maps extraction at scale — thousands of UAE business listings per run
- Business phone numbers are publicly listed and Google-verified
- Geographic + category filtering — target by emirate, district, and business type
- Structured JSON output with n8n-ready format
- Free tier available for low-volume testing
Apify's Limitations
- Business landlines, not personal mobiles — requires Clay enrichment for personal mobile appending
- Data is publicly available — competitors can build the same lists
- Google Maps data accuracy depends on business owners keeping listings current
- B2C personal consumer data is not available via Google Maps

Recommended Tool Stacks by Campaign Type
B2B UAE Campaign (Decision-Makers at Companies)
LinkedIn Lead Gen Agent (outreach + data collection) → Clay (personal mobile enrichment + email verification) → Meta upload with phone + email identifiers. Expected match rate: 45–65%. This stack produces opt-in quality data with the highest compliance profile.
B2B UAE Campaign (Volume-First Approach)
Apollo.io (filter by UAE geography + job title + company size, export 2,000–5,000 contacts) → Clay (personal mobile enrichment, email verification, fill missing fields) → Meta upload. Expected match rate: 35–55%.
B2C UAE Campaign (Local Business Owners and Managers)
Apify Google Maps Scraper (filter by emirate + business category) → Clay (owner personal mobile enrichment where available) → Meta upload with business phone + email. Expected match rate: 20–35% (business phone to personal mobile gap reduces matching).
Social-Audience-Based Campaign (Community Members)
PhantomBuster (LinkedIn Sales Navigator export, or Facebook Group member extraction) → Clay (email + personal mobile enrichment) → Meta upload. Expected match rate: 30–50%, depending on how recently subjects updated their Meta profile data.

Frequently Asked Questions
What is the best tool for finding phone numbers for Meta custom audiences?
For B2B: Apollo for initial discovery + Clay for personal mobile enrichment. For local UAE B2C: Apify's Google Maps Scraper for business phone numbers + Clay to attempt personal mobile appending. For LinkedIn-sourced campaigns: PhantomBuster or the PEESHEE LinkedIn Agent for structured profile extraction + Clay enrichment.
What is the difference between Apollo and Clay?
Apollo is a proprietary database of 270M+ contacts — you search and export from it directly. Clay is an enrichment engine with no proprietary database — it queries 75–150+ external providers to fill gaps in contact records you already have. For best results, use Apollo to find contacts and Clay to enrich and append personal mobile numbers.
Can PhantomBuster scrape phone numbers from LinkedIn?
Rarely. Most LinkedIn users do not display phone numbers publicly. PhantomBuster extracts name, company, job title, and email (where visible). The phone number comes from Clay enrichment after PhantomBuster provides the profile data as an input.
How accurate is Apollo phone data for UAE contacts?
Apollo reports ~90% overall accuracy, but MENA phone data coverage is weaker than US and Western European markets. Expect 40–60% of UAE exports to have a phone number, with a meaningful portion being office lines rather than personal mobiles. Clay enrichment after Apollo export is recommended for UAE campaigns to improve Meta match rates.
Is Apify's Google Maps scraper useful for UAE campaigns?
Yes — for B2B or B2B2C campaigns targeting local businesses (restaurants, clinics, real estate agencies, retailers). Google Maps has comprehensive UAE business listing coverage with verified phone numbers. The limitation is that these are business landlines, not personal mobiles — Clay enrichment is needed to attempt personal mobile appending for the owner or manager.
