# What does NUMERIC_SENDER (Promo Numeric SenderId) mean?

The message was rejected because a **numeric sender ID was used for transactional content** where it is not allowed - for example promo messages must use numeric sender ID per local rules. The message was not sent.

**What you can do:** Use an numeric (or otherwise allowed) sender ID for promotional messages. Check the rules for numeric vs alphanumeric sender for your region and message type.
