lobstr.io can enrich your Sales Navigator leads with verified business phone numbers. When you enable phone enrichment, each profile is checked for a valid business number during the scrape.
Phone number enrichment output
The service focuses on business contact details. You can find:
  • Direct dials.
  • Mobile business numbers.
Personal phone numbers are not included. This keeps you compliant with GDPR, CCPA, and other privacy regulations — contacting someone on a private line requires their explicit consent.

​
How does lobstr.io find these phone numbers?

lobstr.io works with a trusted third-party vendor — ContactOut — which maintains a 100M+ phone number database updated hourly. Numbers are collected from public, compliant sources:
Sources of phone numbers
  • Social networks
  • Website crawls
  • Market research and public info
  • Crowd source and data partners
  • EDGAR SEC filings
  • Other public business records and datasets
From this pool, only numbers that pass a three-layer verification process make it into your output file.

​
How accurate is the phone data?

Enriched phone numbers have 99% confidence. The database updates hourly and each contact passes multiple validation checks before being returned. Success rate depends on region and industry:

South America70%
Asia55%
Africa36%

​
Coverage by industry

Health53%
Other industries~75%
So if you’re enriching sales leads in North America, expect over 75% success. But for Health-sector leads in African countries, success drops to around 20%.

​
How much does phone enrichment cost?

1 valid phone number costs 300 credits. So 1 Sales Navigator lead + a phone number = 301 credits.
Phone enrichment pricing
Based on lobstr.io’s monthly plans, that works out to:
  • ~33 phone numbers for $20 (Starter)
  • ~332 phone numbers for $100 (Pro)
  • ~3,322 phone numbers for $500 (Team)
  • ~6,644 phone numbers for $1,000 (Business)
No phone = 0 credits. You’re charged only when a valid phone number is found.

If you’re using the lobstr.io API, add "mobile_phone": true as a function parameter:

    "functions": {
        "email": false,
        "mobile_phone": true
    }
}

​

​
Will already enriched contacts be enriched again?

No. If a contact has already been enriched with a phone number inside a specific Squid, lobstr.io won’t enrich it again in that same Squid.
Already enriched contacts skipped
This protects you from spending extra phone credits on profiles you’ve already paid for. To re-enrich the same contacts, create a new Squid — a new Squid starts from scratch and enriches all profiles again, which uses new credits.

​
Does it work worldwide?

Yes, phone enrichment is available for profiles from all countries. Coverage quality varies by region and industry — best results come from North America, Europe, and Oceania, and from Sales, Finance, and Technology industries.

​
Can I get personal phone numbers?

No. lobstr.io does not provide personal phone numbers. Personal numbers aren’t GDPR or CCPA compliant for outreach — contacting someone on a private line requires explicit consent. lobstr.io only returns business-related numbers: direct dials, work phones, and mobile business numbers.
Enabling both email and phone enrichment in the same Squid gives you the most complete contact record for each lead. Reaching a prospect by both channels significantly increases response rates.
