What is a business username?

A business username is a searchable identifier for a WhatsApp business phone number, such as ycloud.service. After the username becomes active, customers can use it to search for and find the associated business phone number on WhatsApp. A business username does not replace your phone number or WhatsApp display name. It provides customers with another way to find your business.
Meta reviews every business username before it becomes visible to customers.

​
Username requirements

Your business username must meet all of the following requirements:
  • Be between 3 and 35 characters long
  • Use only English letters (a-z), numbers (0-9), periods (.), and underscores (_)
  • Contain at least one English letter
  • Not contain non-English characters
  • Not begin or end with a period, or contain consecutive periods
  • Not begin with www
  • Not end with a domain suffix such as .com, .org, .net, .int, .edu, .gov, .mil, .us, .in, or .html
Usernames are compared without regard to letter case, but periods and underscores are treated as distinct characters. For example, myID and myid are considered the same username, while myid, my.id, and my_id are different usernames.

Claim a business username

  1. Log in to YCloud and go to WhatsApp Manager > WhatsApp Accounts.
  2. Select the business phone number you want to manage, and open its Settings.
  3. On the Business Profile page, locate Business username and click Edit.
  4. Enter the username you want to claim. The form checks each naming requirement as you type.
  5. Click Submit for review.
  6. Wait for Meta to complete the review. Once approved and activated, the username appears in the Business Profile and customers can use it to find the phone number.
Submitting a username does not make it visible immediately. It becomes available to customers only after Meta approves it.
Business username format checks for the unsaved example ycloud.service.

Review the format checks before submitting. Passing these checks does not mean Meta has approved the username.

The example shows the form before submission; passing the format checks does not mean Meta has approved the username.

​
Edit or delete a business username

To change an active username, return to the Business username section and click Edit, then submit the new username for review. To remove the active username, click Delete. After it is removed, customers can no longer use that username to search for the phone number.
