The 4-device route, and where it breaks
The WhatsApp Business app's linked-devices feature is genuinely useful at small scale: one phone holds the number, and up to 4 more devices, laptops, tablets, other phones, sign into the same account. As of August 2026, Meta's paid Premium tier raises that to around 10 devices in supported markets. For a two-person shop taking orders, this is enough, and it's free.
It breaks the day accountability matters. Every message sends as the same identity, so nobody can tell who promised the customer a discount or who left the 4 pm enquiry hanging. There's no way to assign a chat to a person, no view of who's handling what, and no report on response times.
Two agents open the same conversation, both start typing, and the customer gets two different answers. Past five or six people it isn't a workaround anymore, it's the bottleneck.
What the API route gives a team
On the WhatsApp Business API, your number lives in the cloud and any number of team members reach it through a platform login, no linked phones, no device ceiling from WhatsApp's side.
In Growcord that platform is the shared team inbox: every conversation in one queue, assigned to a specific person, with team roles controlling who can do what. The customer still sees one business number and one continuous chat history; what changes is entirely on your side of the glass.
What multi-user WhatsApp looks like in Growcord
One shared inbox
Every chat on the number lands in a single queue the whole team sees. Nothing lives on one person's phone.
Assignment and ownership
Give each conversation an owner, so 'someone will reply' becomes 'Priya is replying'.
Team roles
Owners, admins and agents get different permissions, billing and campaigns stay with the people who should touch them.
Bots for the off-hours
No-code flows and keyword auto-replies answer instantly at 11 pm, then hand the thread to a human in the morning.
Reports on the queue
Analytics show conversation volumes and how the team is keeping up, visible to managers, invisible to customers.
More numbers when you need them
Sales and support on separate numbers, one workspace. Plans include up to 15 numbers; extras are ₹299/month.

Put your team on one number
Connect the number to Growcord
Meta's embedded signup links your business number to the API in minutes. The free tier lets you test single-user first.
Invite the team
Add members by email on the Startup plan and up, each gets their own login and a role. No SIM swapping, no shared passwords.
Route the conversations
Let auto-replies and bot flows greet instantly, then assign incoming chats to owners so every thread has a name on it.
Add seats as the team grows
Startup includes 3 members, Commerce 10, Enterprise unlimited, and any plan can bolt on a seat for ₹149/month instead of upgrading.
What multiple users on WhatsApp costs
The free app route costs nothing and stays the right answer for one or two people who trust each other completely. The API route on Growcord starts where teams start: Startup at ₹799/month (₹399/month billed yearly) includes 3 team members, 2 WhatsApp numbers, the shared inbox, chatbots and analytics. Commerce (₹999/month billed yearly) carries 10 members, and Enterprise (₹2,999/month billed yearly) removes the seat cap.
An extra seat is ₹149/month on any plan, so growing from 3 agents to 4 costs ₹149, not a tier jump. Meta's conversation fees apply as usual, replying to customers inside the 24-hour window is free on Meta's side, which is most of what a support team does all day. Full details on the pricing page.
Worth naming the alternative people try first: one phone passed around the counter, or WhatsApp Web open on three browsers. It works until the phone goes home in someone's pocket, a chat gets answered twice, or a hot lead sits unread over a weekend. The cost of the fix is a seat price; the cost of the problem is usually a customer.
Give every agent a login, keep one number
Start free, then put 3 team members on the shared inbox from ₹399/month billed yearly.

Frequently asked questions
Can 4 people use one WhatsApp Business number?
Yes. The free WhatsApp Business app allows exactly that: link up to 4 extra devices to the main phone, and everyone shares the account. The catch is that all four work as one identity, no individual logins, no chat assignment, no record of who replied. For more than 4 people, or any accountability, you need the WhatsApp Business API with a platform like Growcord.
How do I use the same WhatsApp number on multiple devices?
In the Business app: Settings, then Linked Devices, then scan the QR code from each extra device, up to 4. On the API, there are no devices to link at all: the number lives in the cloud and every team member signs into the platform from their own browser or phone, wherever they are.
How many users does the WhatsApp Business API support on one number?
WhatsApp itself sets no agent limit on the API. The ceiling comes from your platform's plan. Growcord includes 3 team members on Startup, 10 on Commerce and unlimited on Enterprise, with extra seats at ₹149/month on any plan. All of them work the same number simultaneously from the shared inbox.
Can I see which team member replied to a customer?
On the API, yes, that's much of the point. In Growcord's shared inbox each member has their own login, conversations are assigned to owners, and activity is visible to admins. On the Business app's linked devices this is impossible: every message looks identical regardless of who typed it.
Will customers notice anything different with multiple agents?
No. Customers see one business number, one verified business name and one continuous conversation, exactly as before. Assignment, roles and internal queues are visible only to your team. If anything changes for customers, it's response time, questions stop waiting for whoever holds the phone.
Is multi-user WhatsApp possible without the API?
Only up to the app's limit: 1 phone plus 4 linked devices, all sharing one identity. Beyond that headcount, or the moment you need chat assignment, roles or response reporting. The API is the only sanctioned route. Tools that promise unlimited multi-login by automating the normal WhatsApp app are the ones that get business numbers banned, so the shortcut costs far more than a ₹149 seat does.
