WhatsApp

It lands in the shared inbox

SMS and WhatsApp conversations sit in one list, each labeled with its channel, so everyone with access sees it the moment it comes in.

Someone takes ownership

Assign the conversation to a user. Everyone sees whose it is, and nothing waits for a reply because two people each thought the other had it.

We have 10:30 AM open Saturday. Want it?
Replying from WhatsApp · Local (617) 555-0100

The reply comes from the business

Mara answers from the inbox, over the channel the customer used. Rosa sees the business number, not Mara’s personal cell.

Mara L. Booked Rosa for Saturday 10:30 AM.Internal notePrefers WhatsApp over calls.

The history stays with the business

The whole thread and its internal notes live in the inbox. When someone is out or moves on, the next person picks up where they left off.

Call Assign Resolve

Call back from the same thread

When a message needs a voice, call the customer from the conversation. The call goes out from the business number too.

The same number handles calls, greetings & voicemail.

The inbox is one part of a complete business phone system. Calls to the number get a greeting and extensions, ring the right mobiles or a connected AI agent, and leave transcribed voicemails, all on the number customers message.

Extensions forward to your mobileCreate department or personal extensions, then forward them to the mobiles and phones you already have.
Slack notifications, if you want themGet new-text, missed-call, and voicemail notifications in the channels your team already watches.
Connect AI agentsLet an agent from your AI provider answer an extension, pick up when your team cannot answer, or cover after-hours calls while texts stay in the inbox.

Questions before you switch messaging to Numberline.

Which plans include WhatsApp?
WhatsApp in the shared inbox is included on Grow and Max. Lite includes the shared SMS inbox and voicemail transcripts but not WhatsApp. Every plan includes unlimited users, so adding teammates to the inbox never adds a seat fee. Plan prices are announced at launch; see the pricing page.
Do customers need a new number or app to reach us on WhatsApp?
No. Customers message your Numberline business number on WhatsApp, the same number they call and text. The conversation lands in the shared inbox next to your texts, and replies go back to them over WhatsApp from the shared inbox.
What do I need to set up before texting and WhatsApp are live?
Business texting on a US number requires carrier text-messaging registration for the number; Numberline shows the SMS registration status of each number so you know exactly when texting is live. The setup steps for enabling WhatsApp on a Numberline number are confirmed with you during early access.
Can I bring an existing WhatsApp Business account?
What is confirmed today: WhatsApp on Numberline runs on your Numberline business number, and the team answers from the shared inbox rather than from a phone. Whether an existing WhatsApp Business account or its history can be moved onto that number is confirmed during early access, so ask when you join.
Which numbers work with WhatsApp?
Numberline offers local and toll-free numbers, new or ported. WhatsApp is enabled on your Numberline business number; which number types can be enabled for WhatsApp, and any requirements for a ported number, are confirmed during early access.
How does a team share one inbox without stepping on each other?
Every conversation shows who has it. Assign a conversation to a user, and it is labeled with that person’s name for everyone; unassigned conversations are labeled Unassigned. Anyone with access can read the full history and reply, and the reply always goes out from the business number.

Put WhatsApp & texts where the whole team can answer.

One business number for calls, texts, and WhatsApp, with a shared inbox that shows who has each conversation and replies as the business.
