Here's what changed and how to lock yours in:
1/ No More Phone Numbers
For the first time, people won't need your phone number to message you.
All they'll need is your username.
You keep your number private and still stay reachable.

2/ Claim Yours Before Someone Else Does

Update the app → Settings → Account → Username → pick a name up to 35 characters.
Do it now before someone takes the handle you want.

3/ Grab Your Instagram Handle
Already have the name you want on Instagram or Facebook?
Meta is letting verified creators and businesses claim their existing handle on WhatsApp too, if it's still available.
Same name, all three apps.

4/ Turn On Your Username Key
Add a PIN so strangers can't message you just by knowing your username.
Update the app → Settings → Account → Username → Username Key → set a 4-digit code → turn on "Require key to message."
Now anyone starting a new chat has to enter that code first.

5/ Lock Down Who Can Reach You
Control exactly who gets through.
In the same Username Key menu, toggle on "Ask for key from people who aren't in my contacts."
Your existing contacts skip it.
Strangers get blocked unless you hand them the code.
Change or remove the key anytime without ever touching your username.

7/ Businesses: Numbers Are Changing
For companies, this quietly rewrites how customer identity works.
Meta is moving WhatsApp from a phone-number-only system to a hybrid one.
When a customer messages you by username for the first time, their real number stays hidden.

8/ Meet The BSUID
Instead of a phone number, WhatsApp hands your business a unique string called a Business-Scoped User ID.
That same customer messaging a different company gets a totally different ID.
It stops businesses from cross-referencing or tracking people across platforms.

9/ What Businesses Have To Fix
Since phone numbers aren't guaranteed anymore, any business on the WhatsApp Cloud API has to update their CRM, routing, and chatbots to recognize and log BSUIDs.
Skip it and your conversations break.

10/ The Guardrails
You still can't be spammed cold.
Businesses can't take a list of public usernames and blast marketing at them.
Every conversation still has to be started by the customer.
And if you've talked to a business in the last 30 days, they keep access to your number.
