X Numbers lets users connect through private eight-digit codes without sharing phone numbers.
The feature enables direct messaging and calls within X Chat using private codes.
Users can refresh, hide, or disable X Numbers if their code gets shared.
X introduced X Numbers, a new privacy-focused feature for its Chat service that gives users another way to connect without sharing their personal phone numbers. The feature uses a private numeric code that can be shared with selected people to enable messaging and calls on X.
An X Number is a private eight-digit code that users can create and share with people they want to contact. X says the code is not a phone number and is separate from its Chat safety number system.
The feature allows people to message or call an X user even when they do not follow each other. If a user's inbox is closed, entering the active X Number can allow the conversation to reach the user's inbox rather than the message-request section.

Users can create their X Number through the Chat section of X. According to X's help documentation, users need to open Chat, enter their Chat PIN if prompted, open the inbox dropdown menu, and select Number.
From there, users can enable the feature, share their number, hide it from others, or refresh it to generate a new number.
Refreshing the number makes the previous code unusable for new contacts. Users can also turn the feature off if they no longer want people with the code to contact them.
No. X specifically states that an X Number is not a phone number. It works as an access code within X's Chat system rather than replacing a user's actual mobile number.
It also differs from X's Chat safety number, which helps users verify they are communicating with the intended person.
The feature gives users another way to communicate directly without exchanging personal contact details. X says the system can allow people to connect without following each other or accepting a conventional message request.
This could help event attendees, business contacts, clients, and others who need a direct communication channel without exchanging mobile numbers.

Users should treat their X Number as private contact information. X says people who have already exchanged messages with a user may be able to see the number and could share it with others.
Anyone with the current active number can use it to message or call the user while the number remains enabled. Users who believe their code is shared too widely can disable or refresh it.
Unlike a conventional phone number, an X Number operates only within X's Chat environment. It does not replace the phone number associated with an X account, which can still be used for account security, verification, and other functions.
The feature therefore works more like a private contact code for X Chat than a replacement for mobile telecommunications.
X Numbers arrive as the platform continues developing its Chat experience. The feature was initially made available to some users before officially announcing a broader rollout in September 2026.
For users who want to communicate on X without publicly exchanging a mobile number, X Numbers provide an additional contact mechanism while keeping the interaction within the platform.
