# What does SENDERID_MISMATCH (SenderId Mismatch with template) mean?

The **sender ID you used does not match the template** - for example the template is registered with a different sender ID on DLT or with the operator. The message was not sent.

**What you can do:** Use the sender ID that is registered and approved for the template you are sending. Check your template–sender mapping and fix the sender ID.
