What is number quality rating?
Number quality (quality rating) is a metric that WhatsApp assigns to each business number to indicate how reliable its communication with users is. It is based on real interactions: if people block, report, or mark your messages as spam, quality drops; if they reply and engage, it rises. This score is not a fixed number but a status (low, medium, or high) that Meta updates based on recent behavior.
Why it matters to your SME
If your quality is low, WhatsApp may limit your ability to send messages or even suspend your number. For a business that sells via WhatsApp, that is a headache: you lose communication with customers who have already messaged you. Additionally, low quality affects deliverability, meaning your messages arrive late or not at all. Therefore, taking care of number quality is as important as having good prices.
How it is calculated (what is known)
Meta does not publish the exact formula, but it does share the factors that influence it: user reports (blocks, complaints, marking as spam), response speed, use of approved templates, and message history. New numbers start with medium quality and adjust over time. Sending limits (how many messages you can send per day) depend on this quality and vary by country and business type; therefore, if you want accurate data, it is best to review Meta's official documentation.
Concrete example
Imagine a clothing store that sends offers every day at 7 in the morning. At first, some customers reply, but later they get tired and start blocking the number. Within two weeks, quality drops to low: WhatsApp limits sends and the store cannot notify about a real promo. If instead the store uses WhatsApp only to answer inquiries and sends offers once a week with a useful message, quality stays high and messages arrive without issue.
Common mistakes that lower quality
- Sending messages at annoying times (e.g., early morning) or too frequently.
- Using templates that sound like spam ('You won!', 'Last chance') without context.
- Not offering an opt-out option or ignoring opt-out requests.
- Mixing promotional messages with real conversations without permission.
- Not responding quickly when a customer writes (delay also matters).
How to keep it high
- 1Respond quickly and with useful answers, not empty automated ones.
- 2Send messages only when there is a real reason (a purchase, an appointment, a question).
- 3Always offer an opt-out path (e.g., 'Reply STOP to stop receiving offers').
- 4Segment your list: don't send the same thing to everyone if it's not relevant to them.
- 5Monitor your quality from the Meta dashboard (or from your CRM if it integrates).
Tools like Wando can help you keep quality high because they suggest quick, human responses that your customers value, and they allow you to organize campaigns without falling into spam. But final quality depends on how you use the channel, not the tool.
How it works in practice: a complete example
Let's take a real case: a real estate agency in Buenos Aires that receives WhatsApp inquiries about rentals and purchases.
With Wando, the agency configures the inbox so that AI suggests responses based on customer messages. An interested party asks: 'Is the 2-bedroom in Palermo still available?' The AI suggests: 'Yes, it's still available. Would you like to schedule a visit?' The agent approves with one click and sends it. The response is fast, human, and contextual.
Additionally, the agency uses templates (HSM) to send a visit reminder the next day: 'We'll expect you at 15:00 at the confirmed address. Reply CONFIRM if you're coming.' The customer responds and the conversation continues.
The AI learns from these interactions: if the agent corrects a suggestion, the next time it suggests something better. Thus, the team does not program flows or maintain a chatbot: they only approve or adjust responses that already make sense.
This flow keeps quality high because responses are useful and timely, and promotional messages (like campaigns for new properties) are sent sparingly and with an opt-out option.
What it is confused with and how it differs
Number quality is often confused with the 'verification status' (the blue checkmark) or with the 'message frequency' allowed by WhatsApp.
Verification is a seal of authenticity: it confirms that the business is who it says it is. It has no direct relationship with quality. You can have the checkmark and low quality if your customers report you.
Message frequency (sending limits) is a consequence of quality, not the cause. If your quality is high, the limits are generous; if it drops, they are restricted.
Another common confusion: thinking that quality is the same as open or response rate. No: a customer may open your messages and not report you, but if they never respond, WhatsApp interprets it as lack of interest and quality may drop.
In short, quality is a trust indicator based on user behavior, not marketing metrics.
What happens if you ignore it
Ignoring number quality is not free. The consequences are progressive and concrete.
First, you notice that your messages arrive later than usual. Then, WhatsApp notifies you that your daily sending limit has been reduced. If the situation worsens, your number may be restricted from starting conversations: you can only reply, not send new messages.
In the worst case, Meta suspends the number. That means you lose the chat history, contacts, and the trust of customers who wrote to you through that channel. Recovering it is a slow and bureaucratic process.
For an SME that sells through WhatsApp, this is not a technical detail: it is the difference between continuing to generate revenue or having to rebuild a channel from scratch.
The good news: quality can be monitored and improved. It is not a destination, it is a behavior.
How it relates to Meta's official API
Number quality applies specifically to numbers that use the official WhatsApp API (WhatsApp Cloud API), which is what Wando integrates.
With the API, businesses can send programmatic messages (templates) and receive messages from customers. Quality is evaluated on that number and directly affects sending limits.
Meta updates quality based on signals such as reports, blocks, and response speed. This data is visible in WhatsApp Manager, Meta's dashboard.
The conversation prices that Meta charges vary by country and by conversation type (business-initiated or user-initiated). If your quality drops, you may need more messages to achieve the same conversion, which makes usage more expensive.
To understand the exact details of limits and prices, it is always advisable to review Meta's official documentation, as they change frequently.
When it does NOT apply or is not advisable
Number quality is a concept of the WhatsApp Business API. It does not apply if you use regular WhatsApp or WhatsApp Business (the free app) without the API.
It is also not relevant if your business does not rely on WhatsApp to communicate with customers. If you use the channel only to answer occasional queries and do not do mass sending, quality will rarely be a problem.
Additionally, there are cases where it is better not to use WhatsApp for marketing: if your audience is very sensitive to spam or if the sending volume is low, perhaps email or SMS is more effective.
Quality is also not an indicator of commercial success: you can have high quality and not sell anything if your offer is not good. It is a necessary condition, not a sufficient one, for healthy communication.
In short: paying attention to it makes sense if you use the API to communicate with clients proactively or with high volume.
Common mistakes of those who just understand it
One of the most common mistakes is believing that quality is 'bought' or fixed with a tool. No platform can guarantee high quality: it depends on how you behave with your clients.
Another mistake: thinking that only promotional messages affect quality. Service conversations also count. If you take hours to respond or respond with empty automated replies, quality drops anyway.
Quality is also confused with the number of messages: sending many messages is not bad in itself, but if people do not interact, WhatsApp interprets it as spam.
A typical mistake is not offering an opt-out option in templates. Meta requires that users can easily unsubscribe; if you do not do it, reports accumulate.
Finally, some expect quality to rise immediately after changing their behavior. The metric updates over time and there are no shortcuts: consistency is the key.
Frequently asked questions
How can I see the quality of my number in WhatsApp Business?+
You can see it in the WhatsApp Manager panel, in the phone numbers section. There you'll find the status (low, medium, or high) and the history of the last 7 days. You can also check your current sending limits.
How long does it take for my number quality to go up?+
There is no fixed timeframe: it depends on maintaining good behavior for several days or weeks. If you eliminate the causes of complaints (annoying messages, lack of response) and improve interaction, quality usually recovers gradually.
What happens if my quality is low?+
WhatsApp may limit the number of messages you can send per day, and in extreme cases, suspend your number. The best approach is to act quickly: review which messages generate complaints and adjust your communication strategy.
Does number quality affect only promotional messages?+
No: it affects all messages you send, including customer service ones. If a customer reports you, it also has an impact. That's why it's a good idea to use WhatsApp for real conversations and not just for offer spam.
Does number quality affect messages sent from the free WhatsApp Business app?+
Not directly. Number quality is a concept of the WhatsApp Business API (Cloud API). If you use the free app, you don't see this indicator, and sending limits based on quality don't apply. However, your customers' behavior (blocks, reports) can still affect your reputation and eventually your number.
Can I use Wando to improve my number quality?+
Wando can help you indirectly: by suggesting quick, human responses and allowing you to manage campaigns with moderation, your customers interact more and report less. But final quality depends on how you use the channel: if you send spam, no tool will save you.
What do I do if my quality is low and I don't know why?+
Check the WhatsApp Manager panel to see the last 7 days of history. Look for spikes in messages, annoying hours, or templates with high report rates. Also evaluate whether you're responding quickly to inquiries. Adjust those points and monitor the evolution.
Is number quality the same as verification status?+
No. Verification (the checkmark) confirms that the business is legitimate. Quality measures how trustworthy your communication is based on user behavior. You can have the checkmark and low quality if your customers report you.
