Find Mobile Number

Give it a LinkedIn profile URL, get back that person’s personal mobile number.

What it does

• Resolves a LinkedIn profile URL to the person’s personal mobile phone number.
• Passing first_name, last_name and organization_name alongside the URL raises the hit rate on sparse profiles.
• An empty result means the number could not be found — not that the person has no mobile.
• 12 credits per lookup, charged whether or not a number comes back.

This is the personal line. For the company or office number, use find_work_phone.

Use cases

• Reach a decision-maker who ignores email. For a short list of high-value accounts, the mobile is the channel that still gets answered.
• Chase a late-stage deal. A number is worth 12 credits when the alternative is a stalled opportunity in the final week of a quarter.
• Open a WhatsApp channel. Chain validate_whatsapp to check the number before you message it.
• Follow up on a warm signal. Someone who booked and no-showed, or replied and went quiet, is worth a call rather than another email.

Example prompts

Best prompting practices

• Say “mobile”. Say it explicitly, or your client may reach for find_work_phone and hand you a switchboard number.
• Check credits first. This and find_work_phone are the priciest tools in the catalogue. A 50-row list is 600 credits.
• Cap hard. “Stop after 10 and report credits used” is not optional at this price.
• Make the gate explicit. Number the steps and stop before this one: “list the profiles you are about to call, give me the credit total, and wait for my go-ahead.” Never leave this tool at the end of an unattended chain.
• Pre-qualify the list. Run it on people you have already decided to call, not on a whole export.
• Pass the free identifiers. first_name, last_name and organization_name cost nothing alongside linkedin_url and lift the hit rate — which at 12 credits a miss is the difference that matters.
• Deduplicate and suppress before the run. Numbers you already hold in the CRM are the most expensive rows you can re-buy.
• Forbid retries. “Do not retry empties” stops a client from spending twice on the same profile.
