For 17 years, talking to someone on WhatsApp meant trading phone numbers. That's changing. WhatsApp is adding optional usernames — a public handle you can share instead of your number — and is letting users reserve one now ahead of a wider rollout, the company announced. For the 3 billion-user app owned by Meta, it's a notable privacy upgrade.
What's changing — and how to reserve
Your phone number stays tied to your account; the username is an additional way for people to reach you without seeing your number. To grab one, update to the latest app and head to Settings → Account → Username, per TechCrunch. The full feature is rolling out gradually over the coming months.
The rules are sensible: usernames run 3–35 characters, must include at least one letter, and allow only lowercase letters, numbers, periods and underscores — and they can't start with "www" or look like a web address, a guard against scams. Crucially, there's no public directory: someone has to know your exact username to message you the first time, and you can add a "username key" as an extra gate. To curb impersonation, WhatsApp says it will reserve handles for public figures and major organizations, and businesses can claim their existing Instagram or Facebook usernames.
Why it matters
The headline benefit is privacy. Until now, joining a community group, replying to a business, or chatting with someone you met online often meant exposing your personal phone number — which can't be changed easily and ties to a lot of your identity. Usernames put a buffer in front of it. The move also brings WhatsApp into line with Signal, Telegram and Instagram, which already let you go by a handle.
To be clear about what doesn't change: messages remain end-to-end encrypted (only you and the recipient can read them). Usernames are about how people find and contact you, not the security of the messages themselves — a useful distinction, especially given recent news about attackers targeting messaging apps by tricking users rather than breaking encryption, which Boursel covered.
The business angle
There's a commercial logic here too. Meta has worked to turn WhatsApp into a business-messaging platform, and usernames make it easier for companies and creators to be discovered and contacted without handing out a personal number — feeding the commercial messaging that WhatsApp's business tools monetize. One-to-one chats stay ad-free, but easier business discovery is squarely in Meta's interest.
What to do
Two practical notes. First, reserve early if you want a specific handle — common names will go fast. Second, watch for impersonation: even with WhatsApp reserving big-name handles, scammers may grab lookalike usernames (a swapped letter, an extra underscore), so confirm you're talking to the right account before sharing anything sensitive. The feature is optional — your existing number-based contacts work exactly as before — but for anyone who values keeping their number private, it's worth claiming a username now.
