How WhatsApp decides to restrict a number
WhatsApp does not read your messages. Conversations are end-to-end encrypted, and that is not marketing — it constrains what the enforcement system can possibly act on.
So it acts on signals it can see:
- Reports. How many people press Block or Report after receiving from you. This is the dominant signal by a wide margin.
- Sending pattern. Many messages to people who never messaged you, in a short window, especially from a new number.
- Reply rate. If almost nobody answers you, that looks like broadcasting into a void.
- Account age and history. A number active for years with normal two-way conversation is treated very differently from one registered last week.
Notice what is not on that list: whether your number is linked to a laptop, a desktop app, or an automation platform. Linked devices are a normal WhatsApp feature used by millions.
What actually gets numbers blocked
In order of how often we see it:
- Cold lists. Someone buys or scrapes a list of numbers and messages all of them. The recipients never asked, so they report. This is the number one cause and it is not close.
- Blasting from a brand new number. A number registered yesterday that sends 500 messages today has no history to protect it.
- Identical text at volume. The same message word for word to hundreds of people in minutes is the easiest pattern in the world to detect.
- Ignoring opt-outs. Someone says stop, and the next campaign includes them anyway. That converts an annoyed customer into a reporter.
- Content that violates policy. Prohibited categories get numbers removed regardless of how carefully you send.
What does not get numbers blocked
- Replying to customers who messaged you first. This is the single safest thing you can do on WhatsApp, and it is most of what a support bot does.
- Connecting your number to a computer or a platform through a linked device.
- Sending long messages, images, PDFs or voice notes to people in an open conversation.
- Having an automation answer instead of a human. WhatsApp cannot see whether a person or a bot typed a reply, and does not try.
This distinction matters more than any feature comparison. A business that answers inbound questions all day is in the safest category there is, whichever way its number is connected.
The rules that keep a business number healthy
Let the customer speak first
Build your list from people who message you, from your website, your ads and your storefront — not from a purchased file.
Warm a new number slowly
A number registered this week should not send hundreds of messages this week. Give it real conversations first.
Vary what you send
Personalise. The same sentence sent identically five hundred times is a pattern; five hundred slightly different sentences are conversations.
Spread sends out
Rate limit. A steady trickle looks human; a burst looks like software.
Honour every opt-out immediately
One ignored stop request costs more than the campaign earned.
Watch your reply rate
If a campaign gets almost no replies, stop it. Low engagement is a leading indicator of reports.
If your number does get restricted
- You can appeal from inside WhatsApp. State plainly that you are a business answering your own customers.
- First restrictions are frequently temporary, and are often lifted within hours or days.
- Stop whatever caused it before appealing. Appealing while still sending is how a temporary restriction becomes permanent.
- Never move the same campaign to a second number. That is how one restricted number becomes three.
What we do on our side
Being careful is not only the customer's job. On every number connected to Thikaa:
- Rate limiting on outbound, so no account sends in bursts that look automated.
- Anti-spam guards that stop the same content going out repeatedly.
- Session monitoring every few minutes with automatic reconnection, so a number does not appear to drop and reappear.
- Bulk sends are capped and paced deliberately, well under what the interface would technically allow.
Dozens of customer numbers across Saudi Arabia, the UAE, Egypt and Iraq run on this daily, several for more than a year. We are also willing to say the uncomfortable part: if your plan is to message ten thousand strangers, no platform and no connection method will protect that number, and we will tell you before you pay us.
Frequently asked
Is connecting by QR against WhatsApp policy?
It uses the linked-devices feature that WhatsApp built and supports, the same one behind WhatsApp Web and Desktop. What matters for policy is what you send, not that a device is linked.
Does the official Business API protect me from bans?
No. Official numbers get restricted too, for the same reason: recipients report them. The API adds template review and quality ratings, but a low quality rating on the API also throttles your sending.
How many messages a day is safe?
There is no published number, and anyone quoting one is guessing. What matters is the ratio: messages to people who wrote to you first are near zero risk, messages to strangers carry risk at any volume.
Can I import my customer list and message them?
Existing customers who have dealt with you are far safer than a purchased list, but the safest pattern is still to give them a reason to write first, then reply. If you must reach out, keep it small, spread it out and personalise it.
What happens to my data if a number is restricted?
Your conversations and history in Thikaa are unaffected. You reconnect a number or connect a different one and carry on.
