Bulk Phone Finder by Scalelist

Find verified mobile numbers for any list of leads — from a LinkedIn profile URL alone, or from a name and company.

Powered by Scalelist — the email and phone finder used by over 30,000 users on the Scalelist web app every day.

How it works

Each lead can be identified two ways. Use whichever you have — or both together for the best match rate.

• linkedin_profile_url on its own — no name or company needed.
• first_name + last_name, with company_domain (preferred) or company_name to sharpen the match.

Supplying a LinkedIn profile and a name gives the highest match rate of all. You can mix both styles freely in the same list — every lead is matched independently.

Input

Field	Required	Description
leads[].linkedin_profile_url	Either this…	Full LinkedIn profile URL. Sufficient on its own
leads[].first_name	…or this pair	Lead's first name
leads[].last_name	…or this pair	Lead's last name
leads[].company_domain	Optional	e.g. acmecorp.com — preferred over company name
leads[].company_name	Optional	Use if the domain is unknown

Every lead needs either a linkedin_profile_url or both first_name and last_name. Leads with neither are skipped with a warning; the rest of the run continues.

Example input

{
  "leads": [
    {
      "linkedin_profile_url": "https://www.linkedin.com/in/arnaud-renoux-129aa949/"
    },
    {
      "first_name": "Youssef",
      "last_name": "El Kaddioui",
      "company_domain": "scalelist.com",
      "linkedin_profile_url": "https://www.linkedin.com/in/youssefelkaddioui/"
    },
    {
      "first_name": "Arnaud",
      "last_name": "Renoux",
      "company_name": "Scalelist"
    }
  ]
}
