How to reserve a WhatsApp username

Reserve a WhatsApp username to claim a unique identifier for your business before the feature becomes available in your region. Reserving your username helps protect your preferred business name and makes it easier for customers to recognize your business once usernames are available.

You can reserve your username using either Klaviyo or Meta's WhatsApp Manager — you only need to use one of these methods, not both. Both methods reserve the same username for your WhatsApp Business Account, since Klaviyo's WhatsApp settings connect directly to your Meta account.

Before you begin

Before you reserve a username, keep the following in mind:

• Usernames are unique and can only be assigned to one phone number.
• If your business uses multiple phone numbers, each phone number must have its own username.
• Reserving a username holds it for your business until Meta rolls out WhatsApp usernames in your country.
• Your business profile displays your display name, phone number, and username. Your username does not replace your display name.
• To keep your branding consistent across Meta, reserve the same username you use on Facebook or Instagram. Klaviyo's username field accepts any custom handle that meets WhatsApp's naming rules — it does not currently suggest a username based on your linked Facebook or Instagram accounts.

What happens after you reserve a username?

After you reserve your username:

• Your username is held for your business, so another business can't claim it.
• Your username becomes available after Meta enables WhatsApp usernames in your country.
• Meta notifies you when your reserved username is ready to use.

Change your WhatsApp username in Klaviyo

Either way, after you change your username, your previous username is reserved for 60 days. During this time, only your business can reclaim it. Other businesses can't use your previous username until the 60-day hold ends.
