WhatsApp says the feature is designed to give its three billion users a new layer of control over who can contact them.

WhatsApp will let users go by usernames instead of phone numbers, closing a longstanding privacy gap on the app used by more than three billion people.

The Meta-owned platform said on Monday that it has begun letting users reserve unique usernames before a wider rollout later this year when people will be able to choose to be found and contacted only by their handles.

WhatsApp said the change was designed as a core privacy feature with no public directory of usernames and no autocomplete suggestions, meaning users will need to know someone’s exact username to reach them for the first time.

WhatsApp offers end-to-end encrypted communication across smartphones, tablets and desktop computers. Until now, it has allowed users to be contacted by anyone who has their phone number.

The app said in a blog post that over the “coming months”, users will get the option to be found and contacted only by their username, and not their number. It wasn’t more specific about the timeline.

“We have designed this as a core privacy feature,” Alice Newton-Rex, WhatsApp’s vice president of product, told reporters.

“People will need to know your exact username to contact you for the first time,” she said.

WhatsApp’s current privacy settings are limited to blocking individual users and silencing unknown callers.

The app also allows users to add a profile name, but that’s only displayed in chat groups for other people who don’t have the user’s contact info saved.

A scramble for unique usernames

While people in the United States still prefer text messaging to WhatsApp, the app is widely used in Europe, Asia and much of the rest of the world.

Catchy online handles are highly coveted, and users will likely scramble to claim a desirable one.

“I think a lot of people will go and get usernames, and that’s why we decided to open reservations early,” Newton-Rex said.

Companies, organisations and creators with existing accounts on Meta’s social media platforms, Instagram and Facebook, will get the chance to claim their usernames on WhatsApp.

Usernames need to be three to 35 characters. To prevent impersonation, WhatsApp will hold back usernames for high-profile people or groups, such as celebrities, public figures and government entities.

SpaceX lands on public markets as the sixth largest US company by market value.

SpaceX has debuted on US markets with a market valuation of more than $2 trillion, minting CEO Elon Musk as the world’s first trillionaire.

Shares are set to open on Friday at $150 per share, marking a 6.6 percent increase from the initial public offering (IPO) price, valuing the company at $1.96 trillion putting the aerospace company on track to become the sixth-largest company in the United States.

The company sold $75bn in shares, immediately valuing it at $1.77 trillion. The IPO was oversubscribed four times higher than was otherwise expected, according to the Reuters news agency.

Of the institutional investors allocated, according to Bloomberg News, as much as 70 percent went to what are called long-only investments — a strategy in which holders buy assets based on the expectation that their value will grow over time — and sovereign wealth funds, including those from Saudi Arabia and Kuwait as well.

SpaceX President Gwynne Shotwell and Chief Financial Officer Bret Johnsen rang the Nasdaq MarketSite in New York City opening bell at 9:30am local time as US markets opened.

On Thursday, protesters gathered outside the MarketSite to protest the IPO amid continued allegations that Grok, part of xAI, a subsidiary of SpaceX, allowed users to create non-consensual deepfake sexualised images before the IPO debut.

Shares of SpaceX did not trade until the middle of the trading day as the exchange collected buy and sell orders and underwriters delayed trading until supply and demand were balanced.

“We would expect SpaceX to see an immediate pop in trading due to the hype around the deal, north of 20 percent perhaps,” said Samuel Kerr, global head of equity capital markets at Mergermarket. “Anything lower would actually make me nervous.”

Exchanges and trading firms are eager to avoid the technical mishaps that marred Meta’s 2012 debut. With SpaceX widely viewed as a dress rehearsal for a new generation of mega-listings, market participants will also be watching for signals on investor appetite in advance of forthcoming IPOs for AI heavyweights Anthropic and OpenAI.

The landmark listing cemented Musk’s status as the first trillionaire ever and propelled SpaceX into the ranks of the world’s most valuable companies — even though the firm posted a loss of nearly $5bn last year and generated only a fraction of the revenue brought in by similarly valued tech giants.

The surge comes amid growth driven by its Starlink subsidiary, which drives as much as 80 percent of its revenue.

On Friday, SpaceX launched its Falcon 9 rocket with 29 satellites into space from Cape Canaveral in Florida.
