Consent first
WhatsApp's business policies require that people agree to hear from you before you message them. Bought or scraped lists are not consent.
WhatsApp bulk messaging, the allowed way
WhatsApp bulk messaging and broadcasts: what actually works (and what gets you banned)
People search for 'WhatsApp bulk messaging' or 'WhatsApp disparo' hoping to reach thousands of phones at once. WhatsApp is built to stop exactly that: numbers that message many strangers and get reported or blocked are usually banned, often within hours. There are legitimate ways to send one message to many people, but they all depend on consent. This page explains those options, where a temporary Noir SMS number fits (verifying your own WhatsApp Business account) and where it does not (anything resembling spam, which is prohibited on Noir SMS and closes your account).
- Your own business only
- Refund if no SMS
- US · Canada · UK
Quick answer
Sending unsolicited bulk messages on WhatsApp breaks its terms and usually gets the sending number banned quickly. The allowed options are broadcast lists in the WhatsApp Business app, which only reach contacts who opted in and saved your number, and the official WhatsApp Business Platform (Cloud API) from Meta, which requires opt-in and approved message templates. A Noir SMS number can receive the one-time code to verify your own WhatsApp Business account, but a business account you plan to keep should end up on a number you control long-term.
Highlights
Broadcast lists
In the WhatsApp Business app, a broadcast only reaches contacts who saved your number, so it works for an audience that already knows you.
Official platform
For larger, structured messaging, Meta's WhatsApp Business Platform (Cloud API) uses opt-in, approved templates and quality ratings.
One code, your account
A Noir SMS number can receive the one-time code to verify your own WhatsApp Business account. Move a long-term account to a number you control.
Why unsolicited bulk messaging gets numbers banned
WhatsApp's Terms of Service and Business Messaging Policy prohibit bulk or automated messages to people who did not ask for them, as well as unofficial tools that automate the regular app. Enforcement is largely automatic: a new number sending similar messages to many people who have not saved it, and getting blocked or reported, is a strong spam signal.
The usual result is a ban on the sending number. Evading a ban with a fresh number breaks both WhatsApp's terms and Noir SMS's acceptable-use rules. We do not give tips for avoiding detection.
Option 1: broadcast lists in the WhatsApp Business app
The free WhatsApp Business app lets you create broadcast lists: you pick contacts, write one message, and each person receives it as a normal one-to-one chat. The key rule is built in: a broadcast is only delivered to people who have saved your business number in their phone's contacts. That makes broadcast lists a good fit for customers who already chat with you, and useless for cold outreach.
Lists are capped in size, and limits may change, so check the app.
- Ask customers to save your number, for example on receipts, your website or in-store signs.
- Invite them with a click-to-chat link or QR code so they start the conversation.
- Keep broadcasts relevant and infrequent, and remove anyone who asks to stop.
Option 2: the official WhatsApp Business Platform (Cloud API)
For messaging many customers, such as order notifications or reminders, Meta offers the WhatsApp Business Platform, usually through the Cloud API hosted by Meta or through an official Business Solution Provider. Business-initiated messages generally have to use message templates that Meta reviews, and you need the recipient's opt-in.
The platform has its own Meta pricing, tracks a quality rating for your number, and may cap daily messaging until the number builds a track record.
Where a Noir SMS number fits
Setting up a WhatsApp Business account starts with verifying a phone number by a one-time code. If you want to verify your own business account on a number separate from your personal phone, you can rent a Noir SMS number: choose WhatsApp Business (or WhatsApp) and a country such as the US, Canada or the UK, enter the number, and read the code in your dashboard. If no SMS arrives within the 20-minute reservation, the charge is refunded automatically.
Use it only for your own legitimate business account. Spam, bulk account creation and ban evasion are prohibited, and such accounts are closed.
Why a business account you keep needs a number you control
Noir SMS numbers are single use and recycled later by the provider. WhatsApp may ask you to re-verify the number when you reinstall, change phones or after a security check, and if that number is gone, you may lose access to your business chats and profile. For any business account you plan to keep, turn on two-step verification with a PIN and a recovery email right away, and plan to move the account to a number you control long-term, such as a dedicated business SIM, using WhatsApp's Change number feature.

Frequently asked questions
Can I send bulk WhatsApp messages to a list of numbers I bought?
No. WhatsApp's policies require that recipients opted in to hear from your business. Messaging bought or scraped lists usually leads to fast bans, may break marketing laws, and is prohibited on Noir SMS.
Why didn't my broadcast reach some contacts?
In the WhatsApp Business app, broadcasts are only delivered to people who saved your number in their contacts. Ask customers to save it, or let them start a chat through a click-to-chat link.
Can I use a Noir SMS number for the WhatsApp Cloud API?
It can receive a one-time code for your own business number if Meta accepts it, but our numbers are recycled later. For a production number, use one you control long-term.
My number was banned for spam. Will a new number fix it?
No. Switching numbers to keep doing the same thing is ban evasion, which breaks WhatsApp's terms and our acceptable-use rules. If you believe the ban was a mistake, use WhatsApp's in-app review request.
Is there a legal way to message many customers on WhatsApp?
Yes: get clear opt-in, then use broadcast lists for contacts who saved your number or the official WhatsApp Business Platform with approved templates. Also follow local marketing rules such as the TCPA in the US, CASL in Canada and PECR in the UK.
