01
Define the phone-research scope
Choose a legitimate purpose, source boundary, and expected region.
- Document the authorized business purpose.
- Choose the target websites, business category, keywords, or location.
- Set the expected country or dialing context where available.
- Exclude personal, sensitive, restricted, or unrelated sources.
- Review applicable privacy and communication requirements.
02
Extract from known websites
Use focused public business sources.
- Add complete public website URLs.
- Remove malformed and duplicate entries.
- Set domain and page limits.
- Choose whether internal links may be followed.
- Run a small sample before a large website list.
03
Use keyword-based discovery
Keep discovery terms specific enough to produce relevant businesses.
- Enter a business category, service, product, or other focused keyword.
- Add location context when geography matters.
- Review discovered sources before extracting numbers.
- Remove directories or sources that are outside the authorized scope.
- Save reusable keyword groups only for repeated legitimate research.
04
Normalize and filter phone numbers
Clean formatting differences without hiding uncertainty.
- Choose the expected country or dialing prefix.
- Normalize spaces, punctuation, and common separators.
- Keep extensions in a separate field where supported.
- Remove duplicates, invalid lengths, fax-only entries, and obvious placeholders.
- Retain source URL information for verification.
05
Review and export the result
Pattern detection cannot determine ownership or permission.
- Check representative numbers against the source page.
- Separate business switchboards, department lines, mobile numbers, and uncertain records.
- Remove personal or irrelevant numbers.
- Export only the reviewed fields required for the next workflow.
- Open the exported file and verify format, country code, and row count.
06
Use phone data responsibly
Follow consent, telemarketing, privacy, and do-not-call requirements.
- Confirm a lawful basis before contact.
- Check applicable do-not-call or suppression lists.
- Identify the caller or organization accurately.
- Do not use deceptive, automated, or prohibited calling practices.
- Honor objections and deletion requests.
FAQ
Troubleshooting notes
Common questions that can save a support request.
Why is the country code wrong or missing?
The source may use local formatting without geographic context. Set the expected country and verify uncertain numbers manually.
Why did one number appear in several formats?
Pages may repeat the same number with spaces, punctuation, or country prefixes. Normalize and deduplicate before export.
