We use AWS's SNS service to send text messages with our user's MFA code for logging into our app. In order to send text messages to China, AWS requires us to submit a text template. The text message must include a "signature". The description of the signature that AWS provides is:
- The signature must be prepended to (i.e. in front of) the SMS message body within square brackets or lenticular brackets depending on the message encoding required for your SMS requests.
- If your message contains special characters such as Unicode text, then you must use lenticular brackets to contain the signature.
- U+3010 LEFT LENTICULAR BRACKET
- U+3011 RIGHT LENTICULAR BRACKET
- Example: 【signature】感谢您注册 {####}，您的一次性密码是 {####}。
- The signature must be between 3-11 characters.
- Only Chinese characters are supported.
My Question: what is the signature supposed to look like? My message does not contain unicode text so I'd be using square brackets. Can I just use my company's name for the signature? If my company's name is ACME, could something like this suffice?
[極致] 你好。這是ACME。您的 MFA 代碼是 {####}
Translated to english, this would be:
[ACME] Hi. This is ACME. Your MFA code is {####}
