Meta's health score (High, Medium, Low) for a business number based on how recipients react to its messages.
The phone number quality rating is a measure Meta assigns to each WhatsApp business number, shown as High (green), Medium (yellow), or Low (red). It reflects recent recipient feedback — primarily blocks and reports — over a rolling window.
A High rating means customers are engaging positively; a Low rating signals that too many recipients are blocking or reporting your messages, often from poor opt-in, irrelevant content, or excessive frequency. Sustained low quality can trigger reduced messaging limits or restrictions on the number.
The rating is tied to messaging limits, so maintaining quality is essential to keep your ability to message at scale intact.
Quality rating governs how many people you can message and whether your number stays active — protecting it protects your whole channel.
