WhatsApp Compliance in South Korea
A practical overview of the rules that affect WhatsApp messaging and marketing in South Korea, with a checklist before you launch.
Key Rules for WhatsApp in South Korea
KakaoTalk is the dominant messaging app in South Korea, so WhatsApp suits international audiences; WhatsApp marketing still needs consent under the Network Act and the PIPA.
WhatsApp's popularity varies across Asia; where it is widely used, Meta's policies and the local data protection law both apply to business messaging.
Data Protection
The Personal Information Protection Act (PIPA), enforced by the Personal Information Protection Commission, is one of the strictest privacy laws in Asia.
Keep a record of how each contact was collected, what they agreed to and when, and make it easy for them to withdraw consent.
Practical Checklist
- Use the official WhatsApp Business Platform rather than personal or modified apps, which risk bans.
- Collect opt-in that clearly mentions WhatsApp and your business name, and store a record of it.
- Choose the correct template category and keep utility messages free of promotions.
- Respond within the 24-hour customer service window where possible, and use approved templates outside it.
- Honour opt-outs and blocks, and watch your quality rating in WhatsApp Manager.
Contact data
Format numbers in international E.164 format with the +82 country code, remove duplicates and invalid numbers, and keep consent records linked to each number.
Timing and Language
South Korea follows the Asia/Seoul time zone (UTC+09:00 in October 2026). The usual working week is Monday to Friday. Schedule WhatsApp campaigns for the recipient's local daytime hours, avoid public holidays and religious observances that matter to your audience, and convert send times from IST before scheduling.
In Seoul, customers commonly use Korean, with English. Messages in the customer's preferred language usually perform better, but check how local-language text affects character counts (for SMS) and template approval (for WhatsApp).
Digital Habits and Channels in South Korea
South Korea has among the world's fastest mobile networks, and KakaoTalk is used by almost everyone; Kakao's business message service (AlimTalk for notifications) often replaces SMS. Korean law requires advertising messages to start with the '(광고)' advertising label, include the sender's name and contact details, and obtain separate consent for messages sent between 9 pm and 8 am.
Cards, Kakao Pay, Naver Pay and Samsung Pay dominate payments, and Naver and Coupang are major shopping platforms. Seollal (Lunar New Year) and Chuseok, when gift sets are exchanged, are the biggest retail seasons.
South Korea's economy is led by large conglomerates such as Samsung, Hyundai, SK and LG, which make semiconductors, smartphones, cars, ships and batteries, and the country has very high 5G coverage. VAT is 10%, and prices are in won. Most Koreans live in apartment complexes and use fast delivery services, so time-sensitive delivery updates and coupons are popular. Search and shopping start on Naver as well as Google.
Regulators, Registers and Practical Rules in South Korea
South Korea's PIPC enforces PIPA, and ad messages must start with (광고).
Night-time ads need extra consent.
Under the Information and Communications Network Act, advertising messages need prior consent, must begin with (광고), include the sender's name and contact, and give a free opt-out. Messages sent between 9 pm and 8 am need separate consent. KakaoTalk is the dominant messaging app, and Kakao's business message products are often used instead of SMS. SK Telecom, KT and LG U+ are the operators.
