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:

One API
How sending works
Use the same SMS API across supported destinations. Prepare an eligible sender, enable the destination and apply the recipient permission your message requires. Track the accepted message through carrier submission and the delivery reports available for that route.
Sending to South Korea, answered
What senders ask before their first message to South Korea.
Do I need to register a sender before sending SMS to South Korea?
No registration is required for a long code; confirm availability, ownership and destination access before sending. Registration is unavailable for an alphanumeric sender ID, and the submitted sender ID is overwritten.
Can I use an alphanumeric sender ID in South Korea?
You can submit an alphanumeric sender ID, but registration is unavailable and the carrier overwrites it before delivery.
Can I receive replies from South Korea?
Yes, if you send from a long code. Replies are delivered to you as signed webhooks.
Are there quiet hours for SMS in South Korea?
Quiet hours are recorded here. Confirm the applicable sending window for your message purpose and recipient location.
What other channels can Bird reach South Korea on?
WhatsApp and Voice, from the same account and API.
