How many WhatsApp numbers can a business use?
A business can use as many WhatsApp numbers as it has real reasons for, such as one per branch or one per team, but each number is a separate WhatsApp account with its own chats, its own history and its own risk. Most small businesses do best with one well-used number. This guide explains when a second number makes sense, how to split numbers cleanly, how Spaces treats each one, and why several numbers are never a way to send more.
The short answer
Every WhatsApp account belongs to one phone number. If you want two numbers, you have two accounts, and customers see two different contacts. There is no setting that merges them into one shared number on WhatsApp's side.
In Spaces, a workspace can connect more than one WhatsApp number, and each number is its own account. It has its own warm-up, its own limits and its own place in your dashboard, and each one counts towards your plan.
One number or several?
| Your situation | Usually best | Why |
|---|---|---|
| One shop, office or person | One number | Customers have one number to save, and all the history builds up in one place. |
| Two or more branches in different towns | One number per branch | Local customers message their own branch, and each team answers its own chats. |
| Separate businesses under one owner | One number per business | A bakery and a lettings agency should not share an inbox or a profile. |
| A team that wants sales and support kept apart | Often one number, handed between people | Customers rarely know which team they need. Splitting can leave them messaging the wrong one. |
| You use your personal number for the business | A separate business number | It keeps personal chats away from your AI agent and your team. |
The test is simple. A second number is worth it when customers would naturally think of the two as different places to go. If you would have to explain the difference to them, one number is probably better.
Running more than one number on a phone
Each number needs to be registered on a phone that can receive its verification code. A dual-SIM phone can hold two numbers, and recent versions of WhatsApp and WhatsApp Business let you add a second account in the app on many phones. Check WhatsApp's help pages for what your phone supports, as this changes between versions.
Some owners keep a cheap second phone for the business number. That works well with Spaces, because the phone only needs to stay charged and online so the link stays up, in the same way WhatsApp on a computer works.
Avoid modified or unofficial versions of WhatsApp that promise several accounts or extra features. WhatsApp can ban accounts that use them.
How Spaces treats each number
You scan a QR code with the phone that has the number, the same way you would link WhatsApp on a computer. You do this once for each number. From then on, each number is held to the same limits:
| Action | Spaces limit per account |
|---|---|
| Messages | Up to 200 a day, at least 10 seconds apart |
| New chats | 5 an hour, 10 a day |
| Replies wait a random 10 to 20 seconds, and a new chat waits 1 to 2 minutes, so messages never go out in bursts. WhatsApp shows “typing…” first | eplies wait a random 10 to 20 seconds, and a new chat waits 1 to 2 minutes, so messages never go out in bursts. WhatsApp shows “typing…” first. |
| A new chat only goes to someone who has messaged your number before, or whom you marked as opted in on the Accounts page | new chat only goes to someone who has messaged your number before, or whom you marked as opted in on the Accounts page. |
| The first message to someone new is plain text, with no links, photos, files or voice notes | he first message to someone new is plain text, with no links, photos, files or voice notes. |

| Anyone who says stop, unsubscribe or similar, in English, French or Spanish, is never messaged again from that number | nyone who says stop, unsubscribe or similar, in English, French or Spanish, is never messaged again from that number. |

| When few people answer new chats, Spaces halves new chats, and pauses them if hardly anyone answers. Replies still go out | hen few people answer new chats, Spaces halves new chats, and pauses them if hardly anyone answers. Replies still go out. |
Each newly connected number also starts its own warm-up for new chats. A second number added months after the first starts at the beginning, because it has no history with Spaces and may have little with WhatsApp.
| Since connecting | New chats an hour | New chats a day |
|---|---|---|
| First 24 hours | 0 | 0 |
| Rest of week 1 | 1 | 3 |
| Week 2 | 2 | 6 |
| Weeks 3 and 4 | 3 | 8 |
| After that | 5 | 10 |
Replies to people who message you are not held back by the warm-up, so customers get answers from the first day.
More numbers is not more room
It is tempting to think that two numbers means twice as many new chats. It does not work that way, and it is the quickest way to lose both numbers.
Spreading one campaign across several numbers is working around a limit, and Spaces' Terms rule it out. WhatsApp also watches each number for many new chats without replies, so a batch of new, quiet numbers all starting conversations is close to the exact pattern that gets numbers blocked. Each number should have its own real customers and its own reason to exist.
This is published provider guidance, written in our own words and last updated on 28 Aug 2026. It is advice, not a promise from the platform, and the platform can change what it watches for at any time.
- Connect a number with a real history of conversations, not a brand-new one. Fresh numbers can be blocked after only two or three new chats.
- Wait up to 24 hours after connecting or reconnecting before starting any new chats.
- Leave at least 10 to 20 seconds between messages.
- Keep new chats few, start with people likely to reply, and write first messages that invite an answer. Many new chats without replies is what WhatsApp watches for.
How to split numbers cleanly
- Decide what each number is for, in one sentence, such as "the Leeds branch" or "the lettings side".
- Give each number its own business profile: name, photo, address and hours that match what it is for.
- Put the right number in the right place: each branch page, each Google listing, each shop window.
- Connect each number to Spaces separately and give it a clear name in your dashboard, so nobody mixes them up.
- Give your AI agent separate notes for each number: who it is speaking for, the hours, the prices and who to hand over to.
- Agree what happens when a customer messages the wrong number. Usually the agent answers anyway and gives them the right number for next time.
Example: a bakery with two shops
Here is how two numbers can work for one owner. Names and details are examples.
| Who | Message |
|---|---|
| Customer | Hi, can I order a birthday cake for Saturday? I am near the high street shop. |
| AI agent (Market Street number) | Hi Priya, thanks for messaging Crumb & Co. This is our Market Street shop. Cakes for the high street shop are ordered through their own number, which I can give you, or we can make it here and you collect from Market Street. Which would you prefer? |
| Customer | I will collect from Market Street, that is fine. |
| AI agent (Market Street number) | Lovely. What size and flavour would you like, and what name should go on it? I will pass it to Anna to confirm the price. |
The agent answered on the number the customer chose, explained the other option once, and kept the conversation going. Both numbers stay busy with real customers, which is exactly what keeps them healthy.
Several people, one number
Often what a team really wants is not more numbers but more hands on one number. With Spaces, your AI agent answers on the number, and any chat can be handed to a person on your team. When that happens the agent stays out of that chat until it is handed back.
| What your agent is told | What it means | What to do |
|---|---|---|
| HANDED_OVER | A person on your team took over this chat, so the agent stays out of it. | Nothing. The agent stays out of this chat until it is handed back. |
This keeps customers on one number they already know, keeps the history in one place, and avoids the warm-up and risk of a new number altogether.
What if one number has a problem?
Because each number is a separate account, one being signed out or restricted does not stop the others. Spaces pauses only the account with the problem and tells your agent.
That separation cuts both ways. If one number is restricted, moving its customers or its messages onto another number to carry on is working around the platform, and it puts the second number at risk too. Sort out the first number through WhatsApp's own steps, and keep the other numbers doing what they were already doing.
Common mistakes to avoid
- Buying several new numbers to send more new chats. Each one starts with no history and its own warm-up.
- Using the same profile name and photo on every number, so customers cannot tell them apart.
- Sending the same message from several numbers. Spaces refuses the same cold message sent to many people.
- Forgetting which number is on which listing, so customers end up at the wrong branch.
- Splitting sales and support onto two numbers when customers do not know which they need.
Notes to give your AI agent
You answer for our Market Street shop on this WhatsApp number.
- Opening hours: Tuesday to Saturday, 8am to 4pm.
- If someone wants the high street shop, give them that number once and offer to help here anyway.
- Never message customers of the other shop from this number.
- Mostly reply to people who message us. Only start chats with people on the list I give you.
- If a chat is handed to a person, stay out of it.
- If Spaces says to wait, wait. Never try another number.Who you message
Summing up
A business can run several WhatsApp numbers, but each is a separate account with its own history, warm-up and limits. Use one well-used number unless customers would naturally see your branches or businesses as different places. If you do add numbers, give each a clear purpose and profile, connect each one separately, and never use extra numbers to send more.

FAQ
Can I connect several WhatsApp numbers to Spaces?
Yes. A workspace can connect more than one WhatsApp number, and each number is its own account. Each one counts towards your plan, which the pricing page explains.
Do several numbers share one set of limits?
No. Each number has its own limits and its own warm-up. That does not make extra numbers a way to send more: spreading one campaign across numbers is working around a limit, and Spaces' Terms rule it out.
Can two numbers run on one phone?
Often, yes. A dual-SIM phone can hold two numbers, and recent versions of WhatsApp can add a second account on many phones. Check WhatsApp's help pages for what your phone supports.
Does a second number need to warm up?
Yes. Each newly connected number starts its own warm-up for new chats, and a brand-new number should be used by hand for a week or two before you connect it.
Should sales and support have separate numbers?
Usually not for a small business. Customers rarely know which team they need. One number, with chats handed to the right person, tends to work better.
What happens if one of my numbers is restricted?
Spaces pauses only that account and tells your agent. The other numbers carry on. Do not move the restricted number's customers onto another number to keep going.
Can one AI agent answer on several numbers?
Yes. Your agent can work across every account in the workspace. Give it separate notes for each number, so it always knows which shop or business it is speaking for.
Is it better to use my personal number or a new one?
Many owners move the business to its own number so personal chats stay private. A number with real history is less likely to be restricted, so if you choose a new one, use it by hand first.
