Leads in South Korea
B2B leads in South Korea with mobile numbers and direct dials
The short answer
LeadNumbers builds Korean prospect lists from your written profile and delivers a slice of them every business day. Strongest coverage sits in Seoul, Busan, Incheon, Daejeon, with electronics and semiconductors, automotive supply, heavy industry, technology, gaming the most requested sectors. Numbers arrive in E.164 with the +82 country code format, mobile coverage is strong, though large firms publish direct dials, and outreach has to respect PIPA, which is strict on marketing contact and requires clear consent handling, so every record ships with a named person rather than a company switchboard.

Detail
What South Korea coverage actually looks like
Coverage is not even across a country, and pretending otherwise is how lists go wrong. In South Korea the density sits in Seoul, Busan, Incheon, Daejeon, and mobile coverage is strong, though large firms publish direct dials.
Sector mix matters too. electronics and semiconductors, automotive supply, heavy industry, technology, gaming are the segments where we can hold volume day after day without loosening your profile.
If your profile is narrower than the market can support, we tell you before you buy rather than filling the gap with weaker records.

Numbers that reach a person
Every Korean record ships with a mobile or an explicitly direct line, written in E.164 with the +82 country code format so a dialer loads it without editing.
Company main lines, department numbers, extensions and toll free numbers are thrown out during the audit. A record with no personal number does not ship at all.
Duplicates are removed across your entire account history, so two reps never call the same person from two different files.

Local rules and etiquette
Business outreach in South Korea has to respect PIPA, which is strict on marketing contact and requires clear consent handling. Suppression lists and opt-outs are honoured automatically and anyone who asks to be removed never returns to your file.
Korean is expected outside global technology firms. Calls land best between 10am and 12pm local time, and reps who dial outside that window usually report the country is hard rather than the timing.
You stay the sender and the caller, so your own compliance posture applies. We supply the contact, not the campaign.

How delivery works here
Volume is paced across business days rather than dumped in one file, so a Korean desk has a fresh call list every morning.
Records land in your inbox as a CSV and can be pushed straight into your CRM, tagged by segment so territories stay clean.
Change geography, titles or volume at any time. The next day's batch is built from the updated profile.

FAQ
Questions buyers ask
Does cold calling work in Korea?
Rarely on its own. The data is most useful for account mapping, partner introductions and targeted email.
Can you deliver Korean-language titles?
Titles arrive as published, so you get the local title where that is what the company uses.
What is on every contact you deliver?
Full name, job title, company, a checked work email and a mobile number or confirmed direct dial in international format. Main lines, extensions and toll free numbers are removed before delivery.
What happens if a number is wrong?
Flag it in the portal and a replacement is queued free of charge within fair use limits. Your flag rate stays visible to you at all times.
How is it priced?
From $75 a month for 500 prospects down to 10 cents a contact at higher volume, with five free sample prospects once your profile is confirmed.
