Anti-Money Laundering Office (AMLO)’s guidelines emphasize the following criteria for URLs included in SMS content:
- URLs must direct users to legitimate and verified destinations.
- URLs must not lead to interactive platforms such as direct download sites or forms requiring user input.
- The purpose of the URL must be transparent, lawful, and clearly communicated in the intent registration process.
- URLs that are generated by URL shorteners, such as Bitly, are not allowed as it is considered leading to a platform not belonging to the owner of the Sender Name. These measures aim to enhance transparency and mitigate risks associated with misleading or unauthorized URL use, which could lead to misuse or fraud.
- URLs must be related to the brand sending the message and SMS content must include the brand name associated with the URL.

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 Thailand, answered
What senders ask before their first message to Thailand.
Do I need to register a sender before sending SMS to Thailand?
Registration is optional for an alphanumeric sender ID. You can send before approval, but the sender ID is overwritten until approval and preserved afterward. Registration is unavailable for a long code, and the submitted sender ID is overwritten. For an alphanumeric sender ID the name itself is registered. Confirm how the approved sender is presented on the destination networks.
Can I use an alphanumeric sender ID in Thailand?
Yes. Registration is optional: before approval the carrier overwrites the sender ID, and after approval the approved sender ID is preserved.
How long does sender registration take in Thailand?
The recorded estimate for an alphanumeric sender ID is about 21 business days; confirm timing before launch.
Can I receive replies from Thailand?
Yes, if you send from a long code. Replies are delivered to you as signed webhooks.
Are there quiet hours for SMS in Thailand?
No country-wide sending window is recorded here. Confirm the rules that apply to your message purpose and recipient location.
What other channels can Bird reach Thailand on?
WhatsApp and Voice, from the same account and API.
