# Phone number enrichment from Sales Navigator leads
> Enable phone enrichment in the Sales Navigator Leads Scraper to add verified business phone numbers — direct dials and mobile business lines.
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.
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:
* 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:
### Coverage by region
| Region | Coverage |
| ------------- | -------- |
| North America | 84% |
| Oceania | 77% |
| Europe | 73% |
| South America | 70% |
| Asia | 55% |
| Africa | 36% |
### Coverage by industry
| Industry | Coverage |
| ---------------- | -------- |
| Sales | 90% |
| Finance | 86% |
| Technology | 85% |
| Health | 53% |
| 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.
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.
## How to enable phone number enrichment
Toggle the **Mobile Enrichment** option in your **Sales Navigator Leads Scraper** Squid settings.
If you're using the lobstr.io API, add `"mobile_phone": true` as a function parameter:
```json theme={null}
"params": {
"functions": {
"email": false,
"mobile_phone": true
}
}
```
## In which columns do phone numbers appear?
Phone numbers appear in the `MOBILE PHONE` column of your CSV output.
## 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.
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.
