Sending to Japan, answered

What senders ask before their first message to Japan.

Do I need to register a sender before sending SMS to Japan?
Registration is required for a short code. No registration is required for an alphanumeric sender ID or a long code; confirm availability, ownership and destination access before sending. Work with Bird on short-code assignment, registration and costs. Short codes are country-specific.
Can I use an alphanumeric sender ID in Japan?
The reference lists alphanumeric senders without a registration requirement. Confirm how carriers present the sender ID for your use case.
Can I receive replies from Japan?
Yes, if you send from a short code or a long code. Replies are delivered to you as signed webhooks.
Are there quiet hours for SMS in Japan?
Quiet hours are recorded here. Confirm the applicable sending window for your message purpose and recipient location.
What other channels can Bird reach Japan on?
WhatsApp and Voice, from the same account and API.
