Content guidelines

Truecaller analyses message content so it can quickly detect misconfigurations and suspend senders that break the rules.

Do

• Match content to the sender's category.
• Keep authentication messages limited to the code and its validity.
• Keep transactional messages informational and tied to the user's own transaction.
• Use a display name and logo that clearly represent your business.

Do not

• Include marketing or promotional content in authentication messages.
• Add promotional CTAs or upselling to transactional messages.
• Send promotional content from a service sender.
• Use a generic display name, promotional wording in the name, or a website or email format.
