# 30510: Opt-in example must be complete, branded, and legible

Log Type: APPLICATION

Log Level: ERROR

## Description

The opt-in example provided is cropped, incomplete, illegible, or missing branding that identifies the business collecting consent. If consent is collected through a webform, the example must include a phone number field.

### Possible causes

* The opt-in screenshot is cropped and does not show the business name or logo.
* The text in the image is illegible or blurred.
* Consent is collected through a webform, but the phone number field is missing.

### Possible solutions

* Submit a complete opt-in example that includes all text, buttons, and branding, such as the company name or logo.
* If consent is collected through a webform, make sure it includes a phone number field.
* Ensure the opt-in clearly identifies the business collecting consent.
* Replace blurred or illegible images with a readable example that shows the full opt-in flow.
