AIS Spam Warning

It is recommended to avoid answering calls from the number.​

If you have already answered the call and notice suspicious behavior such as:​

• Pressure tactics or threats ​

• Claiming to represent an organization or authority ​

• Requesting personal information ​

• Suggest you to continue the conversation through another channel ​

Please hang up immediately and dial *1185# to report the number. AIS will further investigate and block the number if necessary.

Yes, calls can still be answered normally, but users should exercise caution.​

This warning message does not necessarily mean the caller is a scammer. It is generated by AIS intelligent systems that:​
