South KoreaChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Aggressive

In one paragraph: South Korea's privacy law bans sending personal data abroad unless you have one of five grounds. The usual one is a separate consent, ticked apart from every other consent. Since September 2025 the 30 European countries need no extra paperwork. But banking, health records, government cloud and detailed maps have hard walls no consent can unlock, and the regulator fines foreign companies often.
The catch: The 'get consent and send it' headline stops being true the moment you touch six areas: bank and payment systems, financial customers' national ID numbers, hospital records, government cloud, detailed mapping data, and personal location services. In those areas the data or the machine holding it must physically sit in South Korea, and in the government cloud case so must the people who run it.
Does this apply to me?: Yes. The regulator fines companies with no Korean office. In July 2026 it fined TikTok's Singapore company and two Apple companies based in Ireland and Singapore for collecting Korean users' data and sending it abroad without a proper legal basis. If your worldwide revenue was 1 trillion won (about $720 million) or more last year, or you held data on an average of 1 million or more people in Korea per day over the last three months of last year, you must appoint a representative in Korea. Since April 2026, if you already own or control a Korean company, that Korean company has to be the representative.High confidence
Can the data leave the country?: In general yes, but only if you have one of five grounds, and the usual one is a separate consent that the person ticks apart from every other consent. Since September 2025 you can also send data to the 27 European Union countries plus Norway, Iceland and Liechtenstein with no extra step at all, because the regulator has formally accepted their protection as equal to Korea's. That is the only such list, and no other country is on it. Six industries override all of this and are covered below.High confidence
What do I have to do to send it abroad?: Korea does not police the destination. It polices your paperwork. There is no banned-country list and no approval application to file: you pick one of the five grounds, and for most companies that means asking each person for a separate transfer consent that lists what goes, where, to whom, for how long and how to refuse. The one destination list that exists is a positive one, and it holds exactly 30 countries: the European Union plus Norway, Iceland and Liechtenstein. Send data anywhere else and you also have to keep security measures, a complaints route and a dispute process in place, and write the transfer into your contract with the recipient.High confidence
Who enforces this — and are they actually working?: The Personal Information Protection Commission, chaired by Song Kyoung-hee, and it is one of the busiest privacy regulators in the world right now. In July 2026 alone it fined the telecoms company KT about 54 billion won (roughly $39 million) over a data breach, fined TikTok about 10.3 billion won (roughly $7.4 million) and Apple about 252 million won (roughly $180,000). It referred KT to prosecutors for obstructing the investigation and asked police to investigate LG U+ for destroying a server before the inquiry started. Finance is separately policed by the Financial Services Commission and the Financial Supervisory Service; health by the health ministry; maps by an inter-agency committee that includes the intelligence service.High confidence
How long must I keep it, and when must I delete it?: Two forces pull in opposite directions. The ceiling: you must destroy personal data without delay once you no longer need it, and destroy it so it cannot be recovered. The floor: other laws make you keep things. An online seller must keep advertising records for 6 months, complaint and dispute records for 3 years, and contract, cancellation, payment and delivery records for 5 years. Almost everyone must keep system access logs for at least 1 year, and 2 years if the system holds data on 50,000 or more people, holds national ID numbers or sensitive data, or belongs to a licensed telecoms carrier. When the two clash, the keeping rule wins, but you must store that data separately from everything else.High confidence
What happens when something goes wrong?: Count two clocks, and in telecoms and finance a third. Under the privacy law you have 72 hours to tell the affected people, and a separate 72 hours to report to the Commission or to the Korea Internet and Security Agency. The reporting clock starts if 1,000 or more people are affected, or if any sensitive data or national ID numbers leaked, or if the cause was someone breaking in from outside. Separately, an internet service provider must report a cyber incident to the science ministry or the same agency immediately. A hospital must also tell the health ministry about a medical-records incident.High confidence
What's the trap?: Five things that will cost you a weekend. One: the children's age line is 14, not 13 or 16, and processing an under-14's data without a parent's consent is a crime punishable by up to five years in prison, not just a fine. Two: hiding or destroying material during a regulator's inspection is itself a crime, and the regulator used it in July 2026. Three: stripping names out of a dataset does not free it. Four: a bank's Korean customers' national ID numbers may not leave the country at all, and any offshore processing of customers' financial transaction data needs a report to the supervisor 30 business days before work starts. Five: if you want to run a personal location service you must be a corporation and be registered, so you cannot serve Korea from abroad with no entity.High confidence
What's about to change?: The privacy regulator started rewriting the rulebook for artificial intelligence. It set up a reform task force on 30 July 2026, ran a public suggestion window from 6 to 31 August 2026, and plans to publish the direction of reform before the end of 2026. Consent-based rules and the block on sending pseudonymised data abroad for research are both explicitly on the table. Separately, Apple's request to export detailed Korean map data has been pending since its deadline was extended in December 2025, and Google's equivalent request was granted in February 2026 on strict conditions, so the mapping picture can move again at any time.High confidence

United StatesChecked 18 August 2026

Depends on your industryWork: HighEnforcement: Active

In one paragraph: In general the United States lets data go anywhere. There is no national privacy law and no permit is needed to move data abroad. Two things bite hard. Six countries are effectively off limits for large amounts of sensitive data, with prison sentences attached. And anything connected to government work must physically stay on American soil.
The catch: The open headline stops the moment you touch one of six areas: government contracting, police records, federal tax records, defence technical data, telecom licences, and bulk sensitive data flowing to China, Russia, Iran, North Korea, Cuba or Venezuela. Also note that the rule that actually binds you is almost always a state law or an industry regulator's rule, not a national privacy act. There isn't one.
Does this apply to me?: Yes. American rules reach a foreign company with no office in the country. California's privacy law applies to any for-profit business that 'does business in California' and crosses one of three thresholds, and physical presence is not one of them. The children's rule covers foreign websites aimed at American children. No state and no federal law requires you to appoint a local representative — a real difference from Europe.High confidence
Can the data leave the country?: It depends entirely on your industry, so the single national answer is misleading. For ordinary consumer or employee data, yes — send it anywhere, no paperwork. But six sectors have hard walls. Government contracting, police data, federal tax data and defence work require the data to physically stay in the United States. Telecom licences restrict which foreign staff may even look at records. And for anyone, sending large volumes of sensitive data to six named countries is now a crime.High confidence
What do I have to do to send it abroad?: For ordinary data, nothing. No standard contract, no government approval, no destination approval list. The model is a blocklist and it is now populated: six countries are named. Before you move large volumes of sensitive data, your only real job is to work out whether a country of concern, or a company or person they control, could end up with access — including through a vendor, an investor or an employee.High confidence
Who enforces this — and are they actually working?: Nobody, and everybody. There is no national privacy regulator. Instead the consumer protection regulator, the health department, the securities regulator, the communications regulator, the Justice Department, all fifty state attorneys general and one dedicated state privacy agency each enforce a slice. Almost all of them are visibly working right now. The one exception is the new national data transfer programme: it is staffed and issuing guidance but has published no enforcement action yet.High confidence
How long must I keep it, and when must I delete it?: There is a strong floor and a weak but growing ceiling. Investment firms must keep some books for six years and most others for three, with the first two years easy to reach. Health providers keep their paperwork for six years. In the other direction, state privacy laws now force you to publish how long you keep each type of data and to stop keeping it longer than you said, and since April 2026 children's data may no longer be kept indefinitely. Where a keep-it rule and a delete-it rule collide, the keep-it rule wins: every state law carves out data you are required by law to retain.High confidence
What happens when something goes wrong?: Count the clocks — there are at least seven, and they disagree. New York financial firms: 72 hours to the state regulator, and only 24 hours to report paying a ransom. Telecom carriers: seven working days to the police agencies and the communications regulator, and you may not warn customers until seven working days after that. Investment and finance firms: 30 days to affected customers. Health organisations: 60 days. Texas and many other states: 30 days to the state attorney general. Listed companies: four working days to disclose a material incident. The overlap, not any single deadline, is what people fail.High confidence
What's the trap?: Five that cost people their weekend. One: the national data transfer programme carries prison — up to twenty years for a deliberate breach. Two: Illinois lets individuals sue over fingerprints and face scans with fixed damages per person, no proof of harm needed, and that is where the largest privacy payouts happen. Three: the children's rule uses under 13, but several state laws use under 18, so a single age gate will not do. Four: government work means American soil, and police data allows only the United States, its territories, tribal lands and Canada. Five: a rule can be printed in the law book and still be unenforceable, because a court has blocked it.High confidence
What's about to change?: Four things in the next twelve months. The national critical infrastructure reporting rule should be finalised in late 2026, which will switch on a 72-hour incident clock and a 24-hour ransom-payment clock for a very wide range of businesses. California's rules on automated decision-making bite on 1 January 2027. The open banking rule is being rewritten after a court blocked it. And a federal privacy bill is moving in Congress, but it is only a bill and binds nobody.High confidence
Hardest industry wall: Government — Criminal Justice Information Services (CJIS) Security Policy
Government — Publication 1075, Tax Information Security Guidelines for Federal, State and Local Agencies
Defence — Defense Federal Acquisition Regulation Supplement clause 252.239-7010, Cloud Computing Services
Telecoms — National security agreement / letter of assurance conditioning a section 214 authorisation, reviewed by the Committee for the Assessment of Foreign Participation in the United States Telecommunications Services Sector
