A Korean subsidiary may want to use the group's global customer database, HR platform, or cloud service. Before enabling the connection, the business should identify what personal data will leave Korea, who will receive or access it, and which Korean legal basis supports the transfer.

Korea's Personal Information Protection Act, usually called PIPA, regulates overseas provision, outsourced processing, and storage of personal data. Its wording also covers provision through access or inquiry. A transfer within the same corporate group therefore needs its own analysis; shared ownership does not supply a legal basis. PIPA, Article 28-8.

1. Map the actual data flows

Ask the Korean business, group IT, HR, and procurement teams to describe the same arrangement together. A vendor contract may identify one supplier while the operating model involves several hosting locations, support teams, and subcontractors.

The map should identify:

• The people concerned, such as customers, employees, or applicants.
• The data fields involved, including any sensitive information.
• The receiving entity, destination countries, and access locations.
• The purpose of each transfer and the recipient's role.
• The transfer method, timing, and retention period.
• Any onward transfer to another country or provider.

For example, a customer support platform and a headquarters marketing database may use overlapping data but serve different purposes. They should not automatically be treated as a single transfer for compliance purposes.

2. Identify an available Korean transfer basis

Article 28-8 provides several routes, each with conditions. These include separate consent to the overseas transfer; a specific provision in a law, treaty, or international agreement; necessary outsourced processing or storage for a contract with the individual, accompanied by the required disclosure or notice; qualifying certification with the required safeguards; and an applicable recognition of equivalent protection by the Personal Information Protection Commission, or PIPC.

The contract route deserves particular care. It concerns processing entrusted to another party or storage necessary for entering into or performing a contract with the individual. It is not a general exception for every transfer that is convenient for a corporate group. Nor is a contract between two group companies, by itself, the relevant contract with the individual.

If relying on certification or equivalent protection, verify the actual recognition, its scope, and its conditions. Familiarity with an overseas privacy regime does not establish eligibility under Korean law. PIPA, Article 28-8(1).

3. Match consent or notice to the real arrangement

For the separate-consent route, the information provided in advance must cover the data items, destination country, timing and method, recipient details, purpose and retention period, and how the person can refuse the transfer and what refusal means.

For qualifying contract-related outsourcing or storage, the law provides for disclosure in the privacy policy or notice through a prescribed method, such as email. A general statement that information may be shared with global affiliates may leave the actual transfer unexplained. PIPA, Article 28-8(1)–(3).

4. Align contracts and operational controls

A transfer basis is one part of compliance. Review the underlying collection and use, third-party provision where relevant, security, individual rights, and onward transfers. PIPA also provides for orders stopping overseas transfers in specified circumstances. PIPA, Articles 28-8, 28-9 and 28-11.

The implementation work should identify who handles access requests, security incidents, deletion, vendor changes, and requests for new uses of the data. Agreements with recipients should support those arrangements. A group's existing data transfer agreement should be checked against the Korean requirements before it is adopted for the Korean operation.

Questions to resolve before launch

Does keeping the main server in Korea end the analysis? Overseas access can still be relevant. Review the access model as well as the server location.

Does a global privacy policy cover the Korean operation? Check its actual disclosures and the legal basis for each transfer. A document's global title does not answer those questions.

What should management approve? A practical decision pack should contain the data flow map, the selected legal basis, the necessary notices or consent process, recipient safeguards, and an owner for future changes.
