To find someone's phone number from their name in Datablist, first find and review their LinkedIn profile, then run the Waterfall Phone Finder on that profile URL. You can use a full name or separate first and last names; a company or school keyword helps distinguish people with similar names.
A name alone may not identify the right person, and a phone number is not guaranteed. This workflow is useful for enriching a professional contact list. If you need a company's publicly listed number, use the website-research workflow.
I recommend reviewing the profile match before paying for a phone lookup. A correct number for the wrong LinkedIn profile still gives you the wrong contact.
📌 The workflow in brief
Import names and a company keyword, run Find LinkedIn Profile, and check the returned title, summary, and confidence. Pass only reviewed profile URLs to Waterfall Phone Finder, then inspect the phone number and status before exporting.

Finding Phone Numbers From a Name: What You Need To Know First
Going from a name to a phone number isn't a one-step process. You need two enrichments running back-to-back: first to find the person's LinkedIn profile, then to find their mobile number.
The good news? Both enrichments run inside Datablist, both are no-code, and both follow the same simple 6-step process.
💡 What Is Datablist?
Datablist is a platform for automating lead generation workflows that allows sales, marketing, and recruiting folks to find, clean, and enrich data using over 60 different tools from AI Agents to Email Finders, data cleaning tools, and more.
If you need to find, clean, or enrich data for your lead lists, Datablist keeps everything in one platform, so you don't have to juggle 5 different subscriptions.
How the Two-Step Process Works
Here's the logic behind it:
↳ You start with a full name or first and last names, plus a useful keyword when available
↳↳ The LinkedIn Profile Finder matches the person and returns their LinkedIn URL
↳↳↳ The Waterfall Phone Finder takes that URL and returns a mobile number
The first enrichment bridges the gap. Once you have a LinkedIn URL, the Waterfall Phone Finder can do what it does best: query multiple data vendors until a provider returns a number or the sequence has no result.
What You Need To Get Started
Start with a Full Name column, or separate First Name and Last Name columns. Add a Keyword column when you know the company, company domain, or school. For example, your input might contain Ava Martin as the full name and Example Company as the keyword. Use your real contact and company values when running the search.
The keyword is optional, but it helps narrow a common name. If you cannot distinguish two matching profiles, leave the row for review rather than sending an uncertain URL to the phone finder.
Already have LinkedIn URLs? Then you can skip the first enrichment entirely and jump straight to the second part of the workflow and use the Waterfall Phone Finder.
Here's a quick summary of both enrichments:
| Waterfall Phone Finder | LinkedIn Profile Finder | |
|---|---|---|
| What It Does | Finds a mobile phone number | Finds a LinkedIn profile URL from a name |
| Input Needed | LinkedIn profile URL | Full name, or first and last names; optional keyword |
| Cost | 500 credits per successful uncached lookup with the default waterfall | 2.5 credits per search |
| Payment Model | Pay only for success | Paid searches use credits |
| Code Required | None | None |
Cost check: A profile search uses 2.5 credits for a completed lookup, including a search with no match. With the default Datablist-funded phone waterfall, a successful uncached lookup costs 500 credits; no-number results and reused cached results are not billed for that phone lookup. Check the estimate before running. Custom provider API keys have separate provider billing.
How To Find Someone's Phone Number From Their Name: The Step-by-Step Workflow
Both enrichments follow a simple 6-step process, so once you've done one, the second will feel like second nature.
📘 Before We Start
If you already have LinkedIn profile URLs, skip the first enrichment and jump straight to the Waterfall Phone Finder section. The LinkedIn Profile Finder is only needed when you do not already have profile URLs.
Finding a LinkedIn Profile From a Name
This enrichment searches from a full name, or separate first and last names, with an optional keyword. It returns a profile URL when a match is found. It costs 2.5 credits per search.
If you want to automate this first step, you can use the LinkedIn Profile Finder API from Python before passing reviewed URLs to your phone lookup.
Step 1: Sign Up & Upload Your Data
First, Sign up for Datablist.com
Then, Upload your CSV or Excel file containing your list of names and company keywords
Step 2: Navigate to the Enrichment
- Click on Enrich in the top menu
- Go to the People tab
- Select Find LinkedIn Profile
Step 3: Set Up the Enrichment
You'll see the following settings:
- Target Country - Select the country where your contacts are based. This helps narrow down the right LinkedIn profiles.
- Skip if not matching name - Enable this to skip candidates rated Very Low confidence by the name-matching logic. It is not an exact-name filter and does not verify identity. Review the returned title, summary, and company context with either setting.
Once you're done with the settings, scroll down to configure your inputs.
Step 4: Configure Your Inputs
Map your name columns to Full Name, or to both First Name and Last Name. Map Keyword when you have a useful company or school value.
Then click Continue to outputs configuration
Step 5: Select Outputs
Add these outputs so you can review the match:
- LinkedIn Page - The LinkedIn profile URL
- LinkedIn Profile Page Title - A page title that may mention a position or company; confirm it when recency matters
- LinkedIn Profile Summary - A search-result summary when available
- Profile Confidence - High, Medium, Low, or Very Low confidence in the match
Click the ⊕ Icons to add them to your collection, then click Instant Run
Step 6: Run the Enrichment
Finally, configure your run settings by clicking on the chevron on the right side of the button. This will allow you to choose between the following options:
- Run on first 10 items: Good for checking results before committing
- Run on first 100 items: Useful if you want to validate larger samples
- Run on first {X} items: Lets you choose how many items you want to process
- Run on all view items: Process your entire list (or view if you've enabled filters)
Once you have chosen your preferred option, click Run on X items
After the run, review rows with a returned LinkedIn URL. Compare the title and summary with the person you intended to find, and inspect Profile Confidence. Missing or uncertain matches should stay out of the phone-finder run.
For an illustrative review, a search for Ava Martin with the keyword Example Company might return a profile with the same name at another employer. Keep that row for review until you can connect it to the intended contact. A High confidence label alone does not establish current employment or identity. Preserve the source name and company beside the returned URL, then run the phone finder only on accepted rows.
💡 Quick Tip
Before running the phone finder, review the LinkedIn Profile Page Titles and Profile Confidence. Use these to identify matches that need a closer look before spending credits on phone number lookups.
Using the Waterfall Phone Finder
Now that you have reviewed LinkedIn URLs, run the phone finder. With the default waterfall, a successful uncached lookup costs 500 credits. No-number results and reused cached results do not incur that phone-lookup charge.
Step 1: Your Data Is Already Ready
If you just ran the LinkedIn Profile Finder, your LinkedIn URLs are already in your collection. No new upload needed. Just continue in the same collection.
If you're starting fresh with a list that already has LinkedIn URLs, upload your CSV or Excel file with the LinkedIn profile URLs.
Step 2: Navigate to the Enrichment
- Click on Enrich in the top menu
- Go to the People tab
- Select the Waterfall Phone Finder
Step 3: Set Up the Enrichment
You'll see the following settings:
- Allowed Cache Age - Results are cached to avoid paying multiple times for the same search. Choose between 30 days, 2 months, or 6 months. Default to 30 days.
The setup is straightforward. No complex configuration needed, just select your cache preference and scroll down to configure your inputs.
Step 4: Configure Your Inputs
Map the reviewed profile-URL column to LinkedIn Profile. Use standard https://www.linkedin.com/in/... URLs: this phone finder does not accept Sales Navigator profile URLs. Convert those URLs first if that is your starting data.
Then click Continue to outputs configuration
Step 5: Select Outputs
The Waterfall Phone Finder returns:
- Phone Number - The returned phone number in international format
- Phone Number Status -
found,not_found,missing_source_data, orinvalid_data - Country - The two-letter country code when available
Click the ⊕ Icons to add them to your collection, then click Instant Run
Step 6: Run the Enrichment
Finally, configure your run settings by clicking on the chevron on the right side of the button. This will allow you to choose between the following options:
- Run on first 10 items: Good for checking results before committing
- Run on first 100 items: Useful if you want to validate larger samples
- Run on first {X} items: Lets you choose how many items you want to process
- Run on all view items: Process your entire list (or view if you've enabled filters)
Once you have chosen your preferred option, click Run on X items
After the run, filter for found and check that Phone Number is filled. The status describes the lookup result; it does not confirm that the person still owns the number or will answer. Keep the LinkedIn URL beside the result so you can trace each number to the reviewed profile.
Review the remaining statuses separately. not_found means the lookup returned no number; missing_source_data or invalid_data calls for checking the input URL before trying again.
Your Key Takeaways
Finding someone's phone number from their name is a two-step process, and both steps are simple:
- Use the LinkedIn Profile Finder to go from a name to a LinkedIn URL (2.5 credits per search)
- Use the Waterfall Phone Finder to go from a LinkedIn URL to a mobile number (500 credits per successful find)
Total cost per contact: 2.5 credits for the LinkedIn search + up to 500 credits if a phone number is found. A completed profile search still uses credits when the phone lookup has no result.

Frequently Asked Questions (FAQ) About Finding Phone Numbers From a Name
How Much Does It Cost to Find a Phone Number From a Name With Datablist?
A completed LinkedIn profile search uses 2.5 credits, including a search with no match. With the default Datablist-funded waterfall, a successful uncached phone lookup costs 500 credits. No-number results and reused cached phone results are not billed for that phone lookup.
Budget up to 502.5 credits for one completed profile search followed by one successful uncached phone lookup. Check the run estimate and current plans; searches with custom API keys have separate provider charges.
Can I Find a Phone Number With Just a First and Last Name?
You can run the profile search from a full name or first and last names. A company or school keyword is optional but helps distinguish people with the same name. You still need a matching LinkedIn profile and available phone data; a name-only search does not guarantee either.
Do I Need to Code or Use an API?
Not at all. Both enrichments are fully no-code. You upload a file, select the enrichment, map your columns, and click run. If you can use a spreadsheet, you can use Datablist.com.
How Long Does the Full Process Take?
Run a small sample to estimate timing for your list. Processing time depends on the number of rows, provider responses, and whether cached results are available. Allow time to review profile matches between the two runs.
What If the LinkedIn Profile Finder Returns the Wrong Person?
The enrichment returns a LinkedIn Profile Page Title that may mention a job or company, plus Profile Confidence when available. Compare those fields with your source contact and inspect ambiguous profiles before running the phone finder. Skip if not matching name skips Very Low confidence candidates; it does not require an exact name or confirm that the person is the contact you intended. Correct the name or keyword when needed, then review the new result before paying for the next lookup.
Does the Waterfall Phone Finder Return Landlines or Mobile Numbers?
The Waterfall Phone Finder is designed to find a contact's mobile number through data providers. Check the returned number and Phone Number Status, and keep the original profile URL. A successful lookup is not a guarantee of current ownership or reachability.
What Happens If No Phone Number Is Found?
You're not charged for the Waterfall Phone Finder if no number is found. A completed LinkedIn profile search still uses credits. Review the credit estimate before the run. If you configure Custom Waterfall with your own API keys, provider charges follow those providers' terms.
Can I Also Find Their Email Address After Getting Their LinkedIn URL?
Yes. Once you have LinkedIn URLs in your collection, you can run Datablist's Waterfall Email Finder or Personal Email Finder on the same data. No re-upload needed, just pick the next enrichment and run it.
Is There a Limit on How Many Phone Numbers I Can Find?
Collection capacity, import limits, and enrichment credits are different limits. Choose a plan that fits your list and check the credit estimate before processing it. The cloud-sync threshold is not the maximum number of rows you can import. See the current plan comparison.
What's the Difference Between This Method and Using the AI Agent for Phone Numbers?
This method uses the Waterfall Phone Finder, which looks up a contact's mobile number. The AI Agent method extracts whatever phone numbers are listed on a company's website, which may be general company or switchboard numbers. If you want to reach someone directly on their mobile, the Waterfall method is what you want.
