# 30910: Campaign rejected: non-English language content detected. A2P 10DLC campaigns must be submitted in English

Log Type: APPLICATION

Log Level: ERROR

## Description

Your A2P 10DLC campaign was rejected because it contains non-English language content. The Campaign Registry (TCR) requires all campaign registration fields, including use case descriptions, sample messages, and opt-in details, to be submitted in English. This applies even if your messaging traffic will be sent in another language.

### Possible causes

* **Non-English use case description:** The campaign description or message flow fields contain text in a language other than English.
* **Non-English sample messages:** Sample messages were submitted in a non-English language without English translations.
* **Mixed-language content:** Fields contain a mix of English and non-English text that reviewers couldn't fully evaluate.

### Possible solutions

* **Translate all campaign fields to English:** Resubmit your campaign with all registration fields written in English, including use case descriptions, sample messages, and opt-in language.
* **Provide English translations alongside non-English samples:** If your actual messages will be sent in another language, provide English translations of sample messages in parentheses or as a note.
* **Review A2P 10DLC registration requirements:** Visit the [A2P 10DLC Campaign Registration Guide](/docs/messaging/compliance/a2p-10dlc) for detailed field requirements.
* **Contact support:** If you believe this rejection is incorrect, [contact support](https://support.twilio.com).
