Finding mobile phone numbers is one of the most challenging aspects of B2B contact discovery. If you're not seeing results from the Phone Finder, here's why and what you can do about it.
Why Mobile Phone Numbers Are Hard to Find
Mobile phone numbers are significantly harder to find than email addresses. Here's the reality:
Phone numbers are rarely published publicly
Professionals protect their mobile numbers more than emails
Phone data changes frequently (people switch carriers, get new numbers)
Privacy regulations limit phone number availability in many regions
Our typical success rate: Out of every 10 LinkedIn profiles or email lookups, we find approximately 3 valid phone number. While this may seem low, it's actually a high success rate compared to industry standards mobile numbers are simply that difficult to obtain.
Where We Source Phone Data
Tomba uses multiple data sources to find phone numbers:
Source | Description |
Website Data | Phone numbers published on company websites, contact pages, and team directories |
B2B Email Records | Associated phone data from business email databases |
Phone numbers linked to professional profiles |
We cross-reference all three sources to maximize the chances of finding a valid phone number for your contacts.
How to Maximize Your Chances
Use Both Email and LinkedIn Methods
For the best results, try finding the phone number using both methods:
Search by Email — Enter the contact's email address
Search by LinkedIn — Use their LinkedIn profile URL
Using both approaches increases your chances because:
Some contacts have phone data linked to their email but not LinkedIn
Others have phone data on LinkedIn but not in email databases
Combining both gives you the highest probability of success
💡 Pro Tip: If one method doesn't return a result, always try the other. This is the most effective strategy for finding mobile numbers.
No Credit Charged If Not Found
You only pay for results.
If Tomba cannot find a phone number for a contact, no credit will be deducted from your account. You're only charged when we successfully return a valid phone number.
Scenario | Credit Used |
Phone number found | ✅ 1 credit |
No phone number found | ❌ 0 credits |
This means you can search freely without worrying about wasting credits on unsuccessful lookups.
We Update Data Monthly
Our phone number database is updated every month to ensure accuracy:
New phone numbers are added regularly
Invalid/disconnected numbers are removed
Data sources are refreshed and verified
If a contact's phone number isn't available today, it may become available in future updates. Consider checking back periodically for high-priority contacts.
Setting Realistic Expectations
Data Type | Typical Success Rate | Difficulty |
Email Address | 70-80% | Moderate |
Phone Number | ~10-15% | Very Hard |
Mobile phone numbers have a lower success rate across the entire industry not just Tomba.
What To Do If No Phone Is Found
Try the other method — If you searched by email, try LinkedIn (and vice versa)
Check back later — Our data updates monthly
Use email for outreach — Start with email, which has higher availability
Try company main line — Use Domain Search to find company phone numbers
Check the contact's LinkedIn — They may have published contact info directly
Frequently Asked Questions
Why did my colleague find a phone but I didn't for the same person?
Phone data availability can change. If someone searched recently and found a number, but you searched later and didn't, the data may have been updated or the source may have changed.
Do you have more phone numbers for certain countries?
Yes, phone number availability varies by region. North America and Europe typically have better coverage than other regions due to data source availability.
Can I request a phone number lookup?
Currently, phone lookups are automated. We don't offer manual research for individual phone numbers, but our monthly updates continuously improve coverage.
Why is email easier to find than phone?
Email addresses are:
Often published on websites and directories
Used in business communications and signatures
Required for professional profiles and registrations
Phone numbers are personal and rarely shared publicly, making them inherently harder to discover.
