XChat Introduces the Amazing 'X Number': Make Calls Without Sharing Your Mobile Number with Strangers

Elon Musk's XChat has made it easy to send messages and make calls without sharing your phone number. Find out how 'X Number' works and whether it can rival WhatsApp in terms of privacy.

San Francisco. Elon Musk's social media platform, X (formerly Twitter), no longer wants to limit itself to just sharing posts. The company is now directly challenging WhatsApp in the messaging and calling space. Revamping its messaging system, X has introduced a new app and in-app feature called XChat. With the recently launched 'X Number' feature, users can now call and message others without sharing their personal mobile numbers. However, there are some crucial details regarding privacy and security that users should know about this service.

What is 'X Number' and how does XChat work without a phone number?

Launched in September 2026, 'X Number' is not a standard phone number linked to a physical SIM card; instead, it is a private code. If you wish to communicate with a new contact, a freelancer, or a business client, you can provide this code instead of your actual mobile number.

You do not need a separate phone number to use XChat; your existing X account is sufficient. Originally released for iPhone (iOS) users in April 2026, this feature is now available within the chat section of the main X app. It allows you to easily connect with anyone while maintaining your privacy.

Is XChat completely safe? What about privacy and security?

Many people believe that all conversations on XChat remain entirely secret, but the reality is slightly different. Messages, photos, videos, and links exchanged between registered XChat users are encrypted (secured). Message Request Security: If the recipient has not registered on XChat, the message sent to them will not be encrypted. Until the recipient accepts your message request, the message is not fully secure.
Metadata Remains Exposed: Even though the content of your message remains secure, information such as who you messaged and when (metadata) is not hidden.

WhatsApp vs. XChat: The New Race for Anonymity

On WhatsApp, your personal messages and calls are already encrypted. Notably, WhatsApp has also introduced a 'Username' feature, allowing people to communicate with strangers without sharing their phone numbers.

Because of this, XChat's claim of "numberless messaging" is not vastly different from what WhatsApp offers. Both companies are moving towards enabling identity creation without a phone number. The only difference is that XChat is linked to your social network and X Number, whereas WhatsApp is integrating this feature directly into its app.

Can XChat Replace WhatsApp?

In terms of features, XChat offers all the essentials, such as HD audio-video calls, file sharing, and group chats. However, the success of any messaging app depends on its user base. Currently, family, friends, and office groups are already active on WhatsApp. XChat is an excellent choice for those who are highly active on X (Twitter) and wish to keep their professional and personal lives separate.
