WhatsApp usernames expose a new emerging market fault line

WhatsApp’s forthcoming username feature was meant to solve a simple privacy problem: meeting a new customer, seller, colleague or community group should not require handing over a mobile number that may also be tied to banking, social media and one’s wider personal life.

Yet the feature has opened a more fundamental argument in some of WhatsApp’s largest emerging markets. The question is no longer merely whether people should use a handle instead of a phone number. It is whether governments, operators and platforms should be able to preserve a verifiable link between a person’s messaging identity and their SIM card.

WhatsApp began allowing people to reserve usernames in June, ahead of a wider rollout. The company says it serves more than three billion people globally, and the reservation process reflects the scale of the impending scramble for digital identities. Associated Press reported that users will eventually be able to be found and contacted by a username rather than their phone number.

The privacy case is compelling. Phone numbers are durable identifiers: they are passed between services, embedded in address books and frequently become the raw material for unsolicited contact. WhatsApp’s proposed design does not create an open directory or offer autocomplete suggestions. A person must know the exact username to initiate contact. Users may also activate a separate username key, requiring a new contact to know both the handle and an additional code.

For many consumers and small businesses, the change could be liberating. A trader can publish a contact identity without making their personal number public; a consumer can join a group without exposing their number to every participant; and a creator can maintain a consistent identity across platforms.

It has been reported that usernames can be between three and 35 characters, while businesses, creators and organisations may claim an existing Facebook or Instagram handle.

However, regulators in India and Algeria see a different risk. Both countries have long treated SIM registration as part of the toolkit for combatting fraud and supporting investigations. In that context, a messaging identity that is more easily separated from a visible telephone number can look less like a privacy upgrade and more like an additional layer between criminals and accountability.

India became the first major test case. Its Ministry of Electronics and Information Technology asked WhatsApp to pause the feature while consultations took place, warning that it could increase phishing, impersonation and “digital arrest” scams. This matters far beyond the country’s borders: India is WhatsApp’s largest market, with more than 854 million users, according to World Population Review.

The concern is not fanciful. In early testing, TechCrunch found handles resembling Indian political figures, celebrities, a major telecom brand and the Reserve Bank of India still available to reserve. A convincing lookalike handle could give an existing bank, police or government impersonation scam a more credible front door. A phone number is not proof of identity, but it can be checked against a known contact or reported through established anti-spam systems. A username may be easier to change, imitate or even weaponise.

Algeria has taken the argument further. Its government has reportedly asked Meta to ensure WhatsApp accounts are connected to locally registered mobile numbers, reflecting concern that hidden numbers could obstruct fraud prevention and investigations. The policy risks are significant: a strict local-number rule could complicate access for roaming visitors, diaspora communities and cross-border workers.

Still, calling this an emerging-market rejection of usernames would overstate the evidence. The feature is optional, and WhatsApp still requires a phone number to create an account. The real dispute is over the visibility of that number to other users - and over whether regulators should be able to require platforms to preserve traceability in the name of public safety.

The sensible path is neither blind faith in platform design nor a return to compulsory public phone-number exposure. WhatsApp must make verification, protection against lookalike handles, rapid reporting and fraud warnings genuinely effective.

Regulators, meanwhile, should be precise about the safeguards they require and transparent about the legal basis for demanding them.

Usernames may be a privacy gain. But in markets where mobile identity, financial fraud and state oversight are tightly intertwined, they are also becoming a test of who controls trust online.
