Rules & regulations
What local regulators expect before you send. Bird applies opt-out handling on every message; the rest depends on the destination.
#### International Sender Prefix `[국외발신]` or `[국제발신]` will be automatically appended to SMS on the operator's end. These phrases mean "Overseas Sending" or "International Sending" respectively. These words are **not** counted in the message length. #### Character Limits One SMS segment can contain up to **140 bytes** only, which is equivalent to: - **140 characters** using GSM-7 encoding - **70 characters** using UCS-2 16-bit encoding #### Concatenated SMS (LMS) Concatenated SMS is known as **LMS** in South Korea. By default, it is **not supported**. Messages may be: - Trimmed - Delivered with different parts - Split into parts that are not received in the correct sequential order
One API
How sending works
You send to every destination through the same endpoint and the same keys. Bird picks a compliant route for the country, applies opt-out handling on every message, and reports delivery from carrier receipts. The country-specific part is which sender you register. The API call does not change.
