WhatsApp best practices to keep your number from being restricted
Consent, frequency, relevance and an easy way out. What lowers the risk of your business number being restricted or banned on WhatsApp, and what to do if it happens.

For many businesses, the WhatsApp number is the main sales channel. It's on the business card, the storefront, Instagram, the delivery van. Losing that number, even for a few days, means unanswered customers and orders that never arrive.
WhatsApp can restrict or ban numbers that get a lot of reports or behave in ways that look like spam. The exact rules aren't published in detail, and they change over time. So this article won't give you magic numbers of "messages per day". It gives you the principles that always apply: talk to people who want to hear from you, be useful, and let them leave whenever they want.
Before anything else, read WhatsApp's official business policy and terms of service. They are the reference that counts, and it's worth reviewing them from time to time.
The principle: the recipient has to want the message
Almost every restriction starts the same way: people receive a message they didn't ask for and tap "report" or "block". Each report signals that the number is bothering people.
The best protection is simple: message people who asked, about what they asked for.
Consent: ask for it and record it
Consent means the person clearly says they agree to receive messages from your business on WhatsApp. Examples of how that happens day to day:
- The customer starts the conversation. Replying to someone who reached out is the most natural use of the channel.
- A form on your website with an unchecked box: "I want to receive updates on WhatsApp".
- At the counter, the staff member asks if the customer wants to receive updates and writes down the answer.
Two things matter:
- Be specific. "Let you know when your order is ready" is different from "send offers every week". If the person agreed to one, don't use it for the other.
- Record it. Note when and how the person agreed. Besides keeping things organized, data protection laws generally expect you to be able to explain why you hold each contact's data.
Never use bought or copied lists
Bought lists, numbers pulled from groups, another company's contacts, a spreadsheet "a friend sent over". None of these people asked to hear from you. It's the fastest way to get many reports at once.
Beyond the risk with WhatsApp, using data from people who didn't authorize it can be a legal problem under data protection laws. A small list of people who want to hear from you is worth more than a big list of strangers.
Make leaving easy, and respect it
Every message that isn't a direct reply to a customer's question should make it clear how to stop receiving them. Something simple, at the end:
If you'd rather not get our offers here anymore, just reply STOP.
And when someone replies "stop", "unsubscribe" or "no more", actually stop. Mark it on the contact with a tag so nobody on the team messages them again by mistake. People who can't find a way out hit "report".
Frequency and relevance
Even people who agreed can get tired. Some common-sense guidelines:
| Do | Avoid |
|---|---|
| Send when there's something useful for that person | Sending every day just to "stay top of mind" |
| Segment contacts by interest with tags | Sending the same offer to your whole list |
| Short messages with just the essentials | Long texts full of emojis and capital letters |
| Business hours | Messages in the middle of the night or early Sunday morning |
| Identify your business in the first line | Messages that look like they're from an unknown number |
Segmenting by interest makes a big difference. Someone who bought cat food doesn't need the dog food promotion. Someone who asked about rentals doesn't want to hear about new homes for sale. Fewer, better-targeted messages bring fewer reports and more replies.
New number: start slowly
A brand-new number that, on day one, sends hundreds of messages to people who never talked to it raises suspicion. If you changed numbers or are just starting:
- Use the number first to reply to people who reach out.
- Tell current customers through the channels you already have (the old number, Instagram, the counter) and ask them to send a message to the new number.
- Increase the number of conversations you start gradually, over several weeks.
- Fill in your business profile: name, photo, description, address and hours. An empty profile looks less trustworthy to recipients.
Other things that help
Don't add people to groups without asking. Adding people to a group they didn't ask to join usually leads to exits and reports.
Be careful with shortened and unfamiliar links. A message with nothing but an unknown link looks like a scam. Say what it is and where it leads.
Reply quickly. A number that has real conversations, with replies back and forth, behaves like a customer service channel, not a broadcasting tool.
Agree on rules with the team. When several people use the same number, they all need to follow the same practices. One agent sending a promotion to the whole list puts everyone's number at risk.
If your number gets restricted
Even with care, it can happen. What to do:
- Read WhatsApp's message carefully. It usually says whether it's a temporary restriction or a ban, and whether there's a time limit.
- Stop any bulk sending. Don't try to get around it with another number doing the same thing.
- Use the official review path. The app itself offers a way to request a review. Explain objectively how you use the number.
- Let customers know through other channels. Instagram, website, email, a sign at the store. Tell them customer service continues and where.
- Review your practices. Look back: did you message people who didn't ask? An old list? Too often? Fix it before you start sending again.
Don't trust anyone who promises to "unban" numbers for a fee. Reviews are handled by WhatsApp itself.
How IntegraWhats helps
IntegraWhats is built for customer service and sales, not bulk messaging. The whole team answers from the same number in a shared inbox, with sectors, queues and first-response time tracking, which keeps the number working as a conversation channel.
In the CRM, tags help record consent, interests and opt-out requests, so nobody on the team messages someone who asked to stop. Forms and the bio-link page give customers a way to reach out on their own. The free plan includes one number and the pixel, with no card required.
Frequently asked questions
How many messages can I send per day without being banned?
There's no official, fixed number. WhatsApp looks at how the number behaves, including reports and blocks. Messaging people who asked, at a reasonable frequency and with useful content, protects you more than any daily limit.
Can I message past customers who never opted in?
The safest approach is not to start promotional conversations with people who never agreed. You can invite these customers through other channels to send you a message and opt in to updates. That way the contact has given consent.
Do data protection laws apply to WhatsApp messages?
In most places, yes. A phone number and chat history are personal data. You generally need a legal basis to use them, such as consent, to inform the person and to let them opt out. If in doubt, check with a professional familiar with the law in your country.
Does switching numbers fix a restriction?
No. If your practices stay the same, the new number will likely run into the same problem. First fix how you send messages. Then, if needed, start with the new number gradually.
