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 Guam, answered

What senders ask before their first message to Guam.

Do I need to register a sender before sending SMS to Guam?
Yes. Every sender here must be registered before it can send: a 10DLC long code. For a 10DLC long code you register your brand and a campaign with The Campaign Registry, then link the number to that campaign. Messages flow once all three are approved.
Can I use an alphanumeric sender ID in Guam?
No. Bird offers a 10DLC long code here instead.
Can I receive replies from Guam?
No. You can send messages here but not receive replies.
What other channels can Bird reach Guam on?
WhatsApp and Voice, from the same account and API.
