SMS Code Provisioning Guidelines
Use an international long code set up for one-way sending. Use this code for both marketing and transactional sends. Manage opt-outs with a web link or customer preference center. These sends automatically include [국제발신] at the beginning of every message. Every message sends as Unicide with a maximum length of 63 characters. South Korea carriers append a short code of 001, 002, 006, 009, or 00777 to the beginning of each long code.
Restricted Content
You’re responsible for complying with local rules and regulations. To ensure compliance, familiarize yourself with the legislation of the local market. Failure to comply can result in service suspension, cancellation, and potential fines. South Korea generally forbids content related, but not limited to, adult and gambling products and services. Send messages only from 9 AM to 9 PM (GMT+09:00).
