Sending to Guam, answered

Common questions about sender registration, two-way replies, and compliance when launching SMS in Guam.

Do I need to register a sender before sending SMS to Guam?

The reference requires registration for every listed sender type: 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. Confirm sender eligibility and destination access before testing the registered number.

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.
