When three people share one WhatsApp number, every new message creates the same question: who's taking this one?
Without an answer, you get one of two outcomes. Two people reply to the same customer, or everyone assumes someone else has it and nobody does. Assigning each chat to a named person fixes both.
There are three ways to do it, depending on your team size and budget. This guide walks through each one, what it can and can't do, and how to choose.
Skip the workarounds. See how RelayThrough lets you assign every WhatsApp chat to a teammate, with no change for your customers.
Request a demo →Assignment gives every conversation three things a shared list can't:
The more people reply, the more this matters.
The free app has no assignment feature. What it does have is labels, which let you colour-code and categorise conversations. With a little discipline, labels can stand in for assignment.
What it can do: it works for two or three people, costs nothing, and builds the habit of assigning every chat.
Where it falls short:
WhatsApp has a paid multi-agent feature that adds real assignment inside the Business app. It lets you connect more devices and assign chats to your sales agents. The multi-agent version allows up to 10 devices instead of four, lets you assign chats to agents, and shows which device or agent sent each message. The maximum number of devices depends on what's included in your Meta Verified or Meta One subscription.
What it can do: it's the quickest official upgrade from the free app, and it keeps the interface your team already knows.
Where it falls short:
Need more than basic assignment? Give each teammate their own login and task tracking on the number you already use.
See How It Works →This is the route most growing teams end up on. Instead of mirroring a phone, you connect your WhatsApp Business number to a shared inbox through the official API. The multi-agent setup is built on the API, which removes the single-device restriction of the standard app, so each agent gets their own login within a shared inbox.
Many platforms also offer rule-based routing, such as round-robin distribution, skill-based routing that sends pricing questions to sales and technical ones to support, and load balancing that caps each agent's active chats. These are optional, and for a small team, simple manual assignment is usually plenty. Check what a provider actually offers before you assume a feature exists.
What it can do: unlimited seats, clear ownership, a central searchable history and per-person accountability, regardless of which phone or laptop anyone uses.
Where it falls short: it costs money, and you'll need to choose a provider, as we covered in our guide to WhatsApp Business app vs API.
| Your situation | Best fit |
|---|---|
| 2-3 people, low volume, tight budget | Method 1: labels |
| 4-10 people who want to stay in the familiar app, and Meta's feature is available to you | Method 2: Meta's multi-agent |
| Growing team, shared history, handovers, accountability | Method 3: shared inbox |
| Regulated industry (clinic, finance) needing a record | Method 3 |
If you're unsure, start with labels this week. If you find yourself wishing for notes, history or a reassign button, you've outgrown it.
Not natively. You can use labels as a manual workaround.
It's tied to a Meta Verified or Meta One subscription, and the device limit depends on the plan. Check the current plans in your app, because availability varies.
On the free app, one phone plus four linked devices. With Meta's multi-agent, up to 10 devices, depending on your subscription. On the API, the number of seats depends on your provider and plan.
Customers see your business number. Whether a name appears depends on how you sign your replies.
Generally no. Ask any provider how they connect an existing number and what happens to your chat history.
