# 30910: Campaign rejected: A2P 10DLC campaigns must be submitted in English

Log Type: APPLICATION

Log Level: ERROR

## Description

Twilio rejects your A2P 10DLC campaign when campaign registration fields include non-English content. Submit the campaign description, `message_flow`, sample messages, and related registration details in English so reviewers can verify your use case and consent flow.

### Possible causes

* The campaign description includes text in a language other than English.
* The `message_flow` field includes non-English opt-in details or disclosures without an English translation for review. ([help.twilio.com](https://help.twilio.com/articles/11847054539547-A2P-10DLC-Campaign-Approval-Best-Practices))
* One or more sample messages are written in another language without an English translation.
* Registration fields contain mixed-language content that does not clearly describe the campaign for verification.

### Possible solutions

* Rewrite all campaign registration fields in English before you resubmit the campaign.
* If your end-user disclosures or message samples are presented in another language, include an English translation in the registration details and in `message_flow` for verification. ([help.twilio.com](https://help.twilio.com/articles/11847054539547-A2P-10DLC-Campaign-Approval-Best-Practices))
* Make sure your sample messages match the registered use case, identify the brand, and include required opt-out language where applicable.
* Review the campaign details requirements, update the rejected fields, and then resubmit the campaign for review.
