Follow these steps to reserve and register the username for your WhatsApp Business number directly from Botmaker.
This is the recommended way if you manage your account from Botmaker.
Step 1: Go to Channels & Integrations › Channels and select WhatsApp.

Step 2: On the corresponding WhatsApp line, click edit to enter its settings.
Step 3: Locate the Username section and click the Choose button.

Step 4: In the Add username window, choose one of the Meta-preapproved suggestions or enter a custom one (5 to 32 characters: letters, numbers, and underscores).

Step 5: Click Save username. You’ll see the confirmation “Username saved! Your request was sent successfully to Meta”.

Note: Meta-preapproved suggestions are processed faster. Custom usernames require a Meta review that can take up to 24 hours and is not guaranteed to be approved.
A username is a public name associated with a single WhatsApp Business phone number. It lets people identify and contact your business without needing to know your phone number, and it protects your brand name from other businesses.
Note: the business username does not hide your phone number in the app; it is a brand-identity feature, not a privacy one.
Reservation opens June 29, 2026 globally. Activation (when the username becomes usable) is rolled out in waves by country: Wave 1 on July 7, Wave 2 on July 20, and global availability around the end of August 2026. Reserving it early protects your brand name even if activation arrives later.
Do Meta-preapproved suggestions also require review?
No. They are processed and activated faster. Only custom usernames require Meta review (up to 24 hours, with no guarantee of approval).
How do I know if my custom username was approved?
Once you save it, the request is sent to Meta. The status is reflected in the channel’s Username column within Botmaker.
Can I have more than one username per number?
No. Each WhatsApp Business number has only one username at a time, and it is unique across all of WhatsApp.
Does reserving the username hide my phone number?
No. The business username does not hide your number in the app.
You can also register your username from Meta’s tools: see the article “How to register your WhatsApp username from Meta Business Manager”. To understand the BSUID identifier and the impact of the change, see the article “WhatsApp introduces usernames and a new account identifier (BSUID)”.
