# New WhatsApp Usernames

> Chatarmin guide: New WhatsApp Usernames

# WhatsApp Usernames Are Coming — Here's What You Need to Know 🚀

Starting June 2026, WhatsApp is rolling out usernames. This changes how your customers find you, how they message you, and how you identify them inside Chatarmin. The good news: it's a net positive for your business, and there's almost nothing you need to do.

***

## 📣 What's Actually Changing?

WhatsApp is introducing optional usernames for all accounts. Think of it like an @handle — a unique, searchable identity for every user on the platform.

* Customers can set a username on their WhatsApp profile. It's optional.
* Users can find and message each other using usernames, without sharing phone numbers.
* Your business gets a username too. Customers can reach you by typing @your\_username directly.
* You set your business username inside your Chatarmin account once the feature goes live. We'll notify you in-app when it's ready.

## 💡 Why This Is Good News for Your Brand

More privacy for customers means more conversations for you.

* **Higher engagement** — Customers are more willing to reach out when they don't have to share their personal phone number to do it.
* **Easy discovery** — Your brand becomes searchable on WhatsApp. Customers find you by typing @your\_username. A direct path to your inbox.
* **New identifier: BSUID** — WhatsApp is replacing phone numbers with a Business-Specific User ID (BSUID) to identify new customers. Chatarmin handles this automatically in the background.
* **Zero work for you** — All technical changes are already live in our system. Nothing to configure on your end.

## ✅ What You Need to Do

* **Nothing technical** — Chatarmin has already implemented BSUID support. You're fully covered.
* **Set your username** — Watch for the in-app notification in Chatarmin and set your brand handle when it goes live in June 2026.
* **Webhook users** — Your customer data now includes the BSUID field. If you consume Chatarmin webhooks, make sure your system handles the new field.
* **Try REQUEST\_CONTACT\_INFO** — Starting May 2026, you can add this new button to your Utility or Marketing templates. When a customer taps it, their phone number is shared with you automatically.

## 🙋 Your Questions, Answered

**What if a customer doesn't set a username?** You keep communicating with them using their phone number. Nothing changes for those customers.

**Will I still see phone numbers in Chatarmin?** For existing customers, yes. For new customers who connect via username, their phone number won't be visible — you'll see their username instead. They can still share their number with you through the REQUEST\_CONTACT\_INFO button.

**Can I ask new customers for their phone number?** Yes. Add the REQUEST\_CONTACT\_INFO button to your Chatarmin flows. Once a customer taps it, their number is shared with you instantly. Available from May 2026.

**Will I be able to see the BSUID?** BSUID is used internally to route messages. It's not visible in Chatarmin. You'll see customer usernames in your inbox instead.

**Can I search customer chats by username?** Yes. For new customers who connect via username, you can search your Chatarmin inbox using their username — just like you search by phone number today.
