WhatsApp for multiple users: how to put a whole team on one number

Karthik Pandian’s tile and sanitaryware showroom in Madurai has one WhatsApp number, painted on the signboard and printed on every estimate. Eight people need it. Three sales staff send catalogues and quotes, two coordinate deliveries, one handles accounts, and Karthik and his sister read everything. For two years the number lived on a phone at the billing counter, and whoever stood nearest picked it up.

He searched for WhatsApp for multiple users and found three different answers. All three are real, and they suit different sizes of team.

First, two things people mix up

“WhatsApp multiple accounts” usually means several numbers on one phone: your personal account and the shop’s, side by side. That’s a different problem. It helps one person manage two numbers. It does nothing for eight people who need one number.

This article is about the second case: one business number, many people replying.

Option 1: linked devices in the free Business app

The WhatsApp Business app lets you link other devices to the phone that holds the number: WhatsApp Web in a browser, the desktop app, other phones. WhatsApp’s help centre puts the limit at up to four linked devices and one phone at a time.

So five people can be on the number without paying anything. The rules that come with it:

• Linked devices keep working when the main phone is offline, but they log out if that phone goes unused for over 14 days.
• WhatsApp disconnects a linked device after 30 days of inactivity.
• Broadcast lists can’t be created or viewed on linked devices, and tablets aren’t supported.
• You link each device by scanning a QR code with the main phone, so whoever holds that phone controls access.

What the app doesn’t give you is ownership. Every linked device shows the same chat list. Nothing marks a chat as Priya’s or as unanswered, and if two people reply at once the customer gets both replies. In a team of three who sit within shouting distance, that’s fine. You shout.

There’s also a quieter risk. A linked device is a full copy of the business’s chats on somebody’s laptop or personal phone. When that person leaves, you have to remember to unlink it from the main phone. Our piece on customers stuck in staff phones covers why that matters more than it seems.

Option 2: Meta’s paid extra devices

Meta sells a way past four devices, still inside the Business app. It calls the feature multi-agent, and it’s included with a Meta Verified for Business subscription or a Meta One business plan.

According to WhatsApp’s help centre, multi-agent lets you:

• connect up to 10 devices instead of four;
• name each device, usually after the person using it;
• assign chats to an agent, and filter to the chats assigned to you;
• see which agent and device sent a message. Customers can’t see any of this.

The number of devices depends on the plan. On Meta Verified for Business, WhatsApp lists up to four devices on Business Standard, six on Business Plus, eight on Business Premium and 10 on Business Max. So the entry plan doesn’t add devices at all. It adds assignment and device names to the four you already had.

Three catches are worth knowing before you pay.

Calls change. Accounts with no more than 4 linked devices receive WhatsApp calls on all of them. With more than 4, calls ring only on the primary phone. A showroom that takes a lot of calls on its WhatsApp number goes back to one handset for those.

Cancelling shrinks the team. If the subscription ends or its benefits change, only the four most recently active devices stay linked.

And it may not be offered to you. WhatsApp’s page says the premium version “may not be available to you yet”, and Meta Verified’s availability depends on your account. Check under Business Tools in the app before you plan around it.

Where Meta One fits

Meta One is the newer subscription, announced in September 2026, with business plans called Essential, Advanced, Expert and Max. Meta’s announcement gave US prices from $14.99 a month for Essential and $49.99 for Advanced. We couldn’t find rupee prices on any Meta page, so we haven’t quoted any.

The sources also disagree on one detail. WhatsApp’s help page lists “more linked devices” and chat assignment under Essential. The launch announcement listed more linked devices under Advanced. Neither page says how many devices each Meta One plan allows. If the device count is why you’re buying, confirm it in the app before you subscribe, and don’t rely on an article, including this one.

Option 3: a team inbox on the WhatsApp Business Platform

The third route leaves the app. The number moves to the WhatsApp Business Platform (many people call it the WhatsApp Business API), which you reach through a provider, and your team works in the provider’s shared inbox in a browser. WhatsApp Business API in India explains how you get onto it.

The difference is that people stop sharing a device and start having their own logins. There’s no linked-device count, because nobody is linking a device. How many users you get is set by the provider’s plan.

A WhatsApp team inbox built this way usually has:

• Assignment: each chat belongs to a person or a team, and an Unassigned list shows what nobody has picked up.
• Teams: sales, deliveries and accounts each see their own queue.
• Internal notes and mentions on the chat, hidden from the customer, so “is 8% off approved?” isn’t asked in a staff group with a screenshot.
• Saved views, such as “mine”, “waiting on us” or “from ads”.
• A contact record beside the chat with tags, notes and past conversations, which stays when staff change.
• Access you can switch off per person, without touching anyone’s phone.

The Platform also opens things the app can’t do at all: approved templates sent to opted-in customers, automated replies and reminders, and messages triggered by your billing or booking software.

What you give up

A WhatsApp shared inbox on the Platform isn’t a free upgrade, and three costs are worth stating plainly.

You pay per message. In the app, chatting is free. On the Platform, Meta charges for templates by category, and since 1 October 2026 it also charges for ordinary replies inside the 24-hour window after the first 1,000 per number per month: ₹0.115 each for Indian numbers, before GST. An illustrative showroom sending 3,500 replies a month would pay for 2,500 of them, about ₹288. That’s small, but it isn’t zero, and our cost guide has fuller examples.

You pay the provider. A monthly plan, usually priced by seats, numbers and contacts.

And the number normally stops working in the WhatsApp app on a phone. Staff who liked answering from their handset now use a browser. Meta does have an arrangement that keeps the same number on the Business app and the Platform together, with conditions of its own, and not every provider offers it. Ask before you move. Also ask about WhatsApp groups if your team relies on them, because a Platform number doesn’t behave like a phone in groups.

The three side by side

	Free app, linked devices	App with paid multi-agent	Team inbox on the Platform
People on the number	Phone plus up to 4 devices	Up to 10 devices, by plan	Set by your provider’s plan
Who owns a chat	Nobody	Assigned agent	Assigned person or team
Internal notes on a chat	No	No	Yes, in most inboxes
Calls	Ring on all devices	Primary phone only above 4 devices	Depends on the provider
Templates and automation	Greeting, away, quick replies	Same	Yes
Meta’s message charges	None	None for chats	Per delivered message
Other cost	None	Meta subscription	Provider subscription

Which one suits your team

Up to five people who sit together and mostly answer enquiries: stay on the free app with linked devices. Agree out loud who answers what. Anything more is money spent on a problem you don’t have.

Six to ten people, mostly chatting one to one, with no need for automated messages: Meta’s paid multi-agent is worth pricing, if it’s offered to your account. You keep the app everyone knows and gain assignment. Check the calls rule first.

More than ten people, or separate teams, or shifts, or any wish to send reminders and order updates automatically: you need the Platform and a team inbox. The same applies below ten people if the real complaint is “nobody knows who replied” or “the customer left with the salesman”. Those are ownership and record problems, and device counts don’t fix them.

Karthik’s eight could have squeezed into the paid tier. He chose the Platform because deliveries wanted automatic dispatch messages and because two salespeople had left the year before with customers on their own phones.

What to ask before you buy a team inbox

Sit through the demo with your own number’s worst day in mind.

1. How many users does each plan include, and what does an extra seat cost?
2. Can a chat be assigned to a team as well as a person, and what does an unassigned chat look like?
3. Can two people be stopped from replying to the same chat at once, or at least see each other?
4. Are internal notes clearly different from replies in the composer? Mixing them up is the mistake customers remember.
5. What happens outside the 24-hour window: does the inbox offer a template, or does the message just fail?
6. Who bills Meta’s message charges, and at what rate compared with Meta’s rate card?
7. Can I remove a person’s access in one place the day they resign?
8. Do WhatsApp calls work, and where do they ring?

Once you’ve chosen, the setting-up is its own job: teams, assignment rules, views and handovers. We wrote that as a step-by-step in the shared WhatsApp inbox setup playbook, using a twelve-person studio as the example, so this article stops at the buying decision. Terms such as template and service message are in the glossary.

Before you decide

Count two things this week: how many people need to reply from the number, and how many chats last month had two replies from different people or none at all. The first number tells you which options are even possible. The second tells you whether you’re buying devices or buying ownership.
