WhatsApp Usernames Strengthens Privacy for Nigerians by Hiding Phone Numbers

WhatsApp is rolling out usernames that let Nigerians chat without sharing phone numbers, boosting privacy and helping reduce spam, scams and unwanted contact.

WhatsApp has begun rolling out global username reservations, introducing a major privacy feature that will allow millions of users, including Nigerians, to connect without revealing their phone numbers.

The update marks one of WhatsApp’s biggest privacy enhancements since the introduction of end-to-end encryption and is expected to have significant implications for users in Nigeria, where the platform has become the country’s dominant messaging service for personal communication, business transactions, community groups and digital commerce, the social media company says in an announcement on Monday.

Once the feature becomes fully available later this year, users who choose to create a username will be able to start conversations without exposing their phone numbers to strangers, new contacts or members of public groups.

For many Nigerians, the feature could help reduce unwanted calls, spam messages, scams and privacy concerns associated with sharing personal mobile numbers in online marketplaces, professional networks, religious organisations, neighbourhood groups and educational communities.

WhatsApp: Username reservations begin ahead of global rollout

WhatsApp began accepting username reservations on Monday, June 29, ahead of the broader rollout scheduled for later this year.

Users will receive an in-app notification when the feature becomes available in their country. Once enabled, usernames can be created through Settings > Account > Username.

The company says the feature is designed for situations where exchanging a phone number may feel unnecessary or uncomfortable.

“When someone new walks into your life—a classmate, a neighbour, someone you meet at an event—sharing a phone number can feel like a big step,” WhatsApp says.

“That’s because a phone number is personal and it’s tied to so many parts of your life. Sometimes you just want to chat without handing over your digits.”

Unlike usernames on traditional social networking platforms, WhatsApp says its usernames are designed primarily as a privacy tool rather than a public online identity.

There will be no public directory for browsing usernames. Instead, someone will need to know a user’s exact username before initiating a conversation, limiting unsolicited contact.

To further strengthen user protection, WhatsApp is introducing an optional username key, which acts as a second credential that users can require before receiving an initial message from someone who does not already have their contact details.

The additional verification layer is designed to reduce impersonation attempts and make it more difficult for scammers to contact users using guessed usernames.

Why Nigerians should reserve usernames early

According to WhatsApp, reservations are opening months before the full launch because of the enormous scale of its global community, which now exceeds three billion users.

With billions of people sharing similar names, the company says early reservations give users a better opportunity to secure their preferred usernames before they become unavailable.

For users who cannot obtain their preferred name, WhatsApp has introduced a username generator that suggests alternative options.

The feature also supports creators, businesses and organisations seeking consistent digital identities by allowing eligible accounts to claim usernames that match their existing Instagram or Facebook accounts.

“We also know that some people like creators, small businesses, and organizations may want to maintain a consistent presence online. For them, we reserved an option to claim their existing Instagram or Facebook username on WhatsApp,” the company says.

What the WhatsApp update means for Nigerian users

The introduction of usernames brings WhatsApp closer to competing messaging platforms such as Signal and Telegram, both of which have long allowed users to communicate without exchanging phone numbers.

For Nigerians, the update could significantly improve digital privacy at a time when concerns over identity theft, online fraud, unsolicited marketing messages and social engineering attacks continue to grow.

The feature may prove particularly valuable for:

• Small business owners communicating with first-time customers.
• Buyers and sellers on online marketplaces.
• Students participating in school groups.
• Community and religious organisations.
• Professionals networking with new contacts.
• Event organisers and volunteers managing large WhatsApp groups.

Importantly, the company says usernames will remain entirely optional. Users who prefer to continue sharing their phone numbers can use WhatsApp exactly as they do today.

WhatsApp also says it is building additional safeguards into the rollout, including preventing public searches for usernames and requiring people to know a user’s exact username, and, where enabled, their username key, before they can initiate contact.

As the feature rolls out globally over the coming months, it is expected to give Nigerian users greater control over how they communicate online, allowing them to protect their personal phone numbers while continuing to use one of the country’s most widely used digital communications platforms.
