Decompiled WhatsApp and found details about their upcoming username system.
Note: There's no official timeline for when this rolls out to everyone. Based on the code, Meta will likely do a gradual rollout - starting with 5% of users, then 10%, 20%, etc. This prevents server overload and lets them fix bugs as they scale. So don't expect it overnight.
1. Matching Account Verification
If the username you want already exists on Facebook or Instagram under someone else's account, you have to prove it's yours by linking that account. Code says: "To use it, connect to this Facebook account". Prevents username squatting across platforms.
2. Key System
Every username gets a unique key. Strangers need this key to message you. Prevents spam.
3. Delete Delay
Delete your username and someone can grab it - but not immediately. There's a delay to prevent bots from snatching it.
4. Number Privacy
Found you by username? They won't see your number. Already know you? They will. Smart privacy feature.
5. Changes Broadcast
Change your username and everyone gets notified. Can't hide it.
6. Business Accounts Need Matching Identity
If you're using WhatsApp Business, you can't just claim any username. System checks if you own the matching business account on Facebook/Instagram. Personal accounts can't pretend to be businesses. Has to be verified.
7. Web Links
wa.me/@username instead of sharing phone numbers. Auto-updates when you change it.
8. Optional vs Required
Personal: username optional. Business: strongly pushed.
9. Groups Get Usernames
Groups and Channels can have @handles instead of long invite links.
10. Reserved Names
Apple, Nike, all big brands locked down. "username_reserved_list" in code.
11. Username Restrictions
System has logic to block certain usernames. Code references forbidden patterns and validation checks. Likely prevents things like offensive content or patterns that look suspicious, but exact restrictions aren't fully visible in the code.
12. Production Ready
Protocol called MexUsernamePinProtocolApi. Full infrastructure with UsernameCheck, UsernameGet, UsernameSet, UsernamePinSet. This isn't a test feature.
13. Cooldown Between Changes
Change your username and you're locked from changing it again for a period. Code has "change_username_cooldown" but exact duration isn't clear. Prevents spamming username changes.
14. Waitlist System
Found "waitlist_state_provider". Meta might give verified accounts first access. Not confirmed active yet.
15. Release Delay Protection
Deleted usernames don't go live instantly. Code has "username_release_delay". Stops bot transfers.
Reality check: This isn't just usernames. WhatsApp is becoming a full platform to rival Telegram. Identity verification, channels, business pages, anti-spam - this is the foundation for something way bigger.
