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.

What this market refuses

Content should include the brandname.

Strictly no political, religious, racial, unsolicited promotion, adult, part time, gambling, fake loan, fake job or fake crypto content.

The character "กู้" in Thai means "loan" that it's not allowed.

One API

How sending works

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?
The reference requires registration for every listed sender type: an alphanumeric sender ID and a long code. For an alphanumeric sender ID the name itself is registered. Confirm how the approved sender is presented on the destination networks. A phone number is registered for this country before it can send business messages.
Can I use an alphanumeric sender ID in Thailand?
Yes, once the sender ID has been registered. Confirm how carriers present it to recipients.
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.
