Mobile number finders for direct outreach.
Mobile number finders look up a person's cell number from a name, company or profile. See how the tools differ and what each vendor says about where its numbers come from.
A mobile number finder takes a contact you already know of, usually a name and a company or a LinkedIn profile, and returns a mobile number if it has one. Some work as a browser extension, some inside a database, some through an API.
Hit rates and sources are the questions that matter, and they are also the ones vendors answer least precisely. These pages report what each vendor says and avoid putting a number on it ourselves.
What you give it
Check whether it needs a name and company, an email or a profile link, and whether it takes a list or one contact at a time.
What you get back
Find out whether it returns a mobile, a direct dial or both, and whether it labels them.
How it is priced
Look for what counts as a used credit: a search, a match, or a revealed number.
What it says about its sources
Read the vendor's own statements on where numbers come from and how they are kept up to date.

Frequently asked questions
A mobile number finder takes a contact you already know of, usually a name and company or a LinkedIn profile, and returns a cell number if it has one. Some run as browser extensions, some inside databases and some through an API.
Often a cell reaches the person more directly, but it depends on the person and the number. The check looks at the number itself.
Most take a list upload or an API call, though some work one contact at a time in a browser. Check each vendor's own help pages for batch size, rate limits and whether results can be exported to a file.
Vendors differ and rarely explain in detail. Common sources include contributed contact books, public records, partner databases and data from other providers. Read the vendor's own statement on sources, and ask whether the people whose numbers are held have agreed to that use.
Pricing usually runs on credits, and the useful question is what spends one. Some charge per search, some per match and some only when you reveal a number. A cheap credit that rarely returns a mobile can cost more than a pricier one that does.
Vendors state hit rates in their own terms, and results vary widely by role, seniority and industry. The only reliable number is the one you get by running a sample of your own contacts and counting how many come back with a mobile.
Rules differ by country and state. In the US, the Do Not Call registry and restrictions on automated dialing to cell phones can apply. This is a question for your own lawyer, and a vendor's terms of service may add limits on use.
No. It only means a number exists. It could be old, shared, forwarded or belong to someone else. A check of the number tells you whether the contact is High chance, Low chance or Bad data before a rep spends time on it.
Common ones are buying before testing a sample, dialing straight from the export, mixing mobiles with desk lines in one field, and paying for repeat lookups on contacts already in the CRM. Keep a record of what was found and when.
Run it on contacts that have an email or profile but no phone. Export the results, check the numbers, then load the High chance ones into the dialer. Contacts that come back Low chance or Bad data can get an email or a LinkedIn message instead.
