How does Lobstr.io collect phone numbers from Sales Navigator profiles?

Lobstr.io can enrich your Sales Navigator leads with verified business phone numbers. When you enable phone enrichment in your Sales Navigator Leads Scraper, each profile is checked for a valid business number.

The phone enrichment service focuses on business contact details. You can find:

• Direct dials.
• Mobile business numbers

Personal phone numbers are not included. This helps you stay compliant with GDPR, CCPA, and other privacy regulations.

How does Lobstr.io find these phone numbers?

We work with a trusted third party vendor i.e. ContactOut with 100M+ phone numbers database (updated hourly). The phone numbers are collected from public and compliant sources.

• Social networks
• Website crawls
• Market research and public info
• Crowd source and data partners
• EDGAR SEC filings
• Many other public business records and datasets

From this pool, only numbers that pass a 3 layer verification process make it to the final output file.

How accurate is the phone data?

Enriched phone numbers have 99% confidence. The database updates hourly and each contact goes through multiple checks to make sure each number is valid and active before you see it.

The enrichment success rate however depends on the region and the industry of your leads.

Coverage by region:

• 84% in North America
• 77% in Oceania
• 73% in Europe
• 70% in South America
• 55% in Asia
• 36% in Africa

Coverage by industry:

• Sales 90%
• Finance 86%
• Technology 85%
• Health 53%
• Other industries around 75%

So, for instance, you're trying to enrich sales leads from North America, you'll be able to enrich more than 75% of the leads with valid phone numbers.

But if you're trying to enrich Health sector leads in African countries, the success rate will be around 20%.

How much does phone enrichment cost?

1 valid phone number costs 300 credits. So 1 Sales Navigator lead + a phone number will cost you 301 credits.

Which plan is most suitable for you?

• 1000 phone numbers cost $250 (pro plan)
• 3000 phone numbers cost $500 (business plan)
• 5000 phone numbers cost $800 (enterprises plan)

No phone = 0 credits

You're charged only when a valid phone number is found. No phone number found = no credits charged.

How to enable phone number enrichment?

To enable this feature, toggle the Mobile Enrichment option in your Sales Navigator Lead Scraper Squid Settings.

If you're using Lobstr.io API, you can add "mobile_phone": true function parameter.

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

In which columns will phone numbers appear in the output file?

You can find the phone numbers in your CSV output. The column name is MOBILE PHONE column.

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 will not enrich it again in the same squid.

This protects you from consuming extra phone credits on profiles you already paid for.

If you want to re enrich the same contacts, you can create a new squid. A new squid starts from scratch and enriches all profiles again, which will use new credits.

Does it work worldwide?

Yes, the phone enrichment feature is available for profiles from all countries.

Coverage quality however varies by region and industry, so you will see the best results in regions like North America, Europe, and Oceania, and in industries like Sales, Finance, and Technology.

Can I get personal phone numbers?

No. Lobstr.io does not provide personal phone numbers.

Personal numbers are not GDPR or CCPA compliant for outreach, since contacting someone on a private line requires explicit consent.

We only return business related phone numbers such as direct dials, work phones, and mobile business numbers.
