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.

Sending to Sri Lanka, answered

What senders ask before their first message to Sri Lanka.

Do I need to register a sender before sending SMS to Sri Lanka?

Only for an alphanumeric sender ID. A long code can send without registration. For an alphanumeric sender ID the name itself is registered, so recipients see exactly the name that was approved.

Can I use an alphanumeric sender ID in Sri Lanka?

Yes, once the sender ID has been registered.

How long does sender registration take in Sri Lanka?

Registering an alphanumeric sender ID takes about 7 business days.

Can I receive replies from Sri Lanka?

Yes, if you send from a long code. Replies are delivered to you as signed webhooks.

Are there quiet hours for SMS in Sri Lanka?

Yes. Local rules limit the hours in which you can send.

What other channels can Bird reach Sri Lanka on?

WhatsApp and Voice, from the same account and API.
