Telegram’s default behavior (before recent strong privacy updates) often leaned towards showing numbers to mutual contacts. Even with “My Contacts” settings, the exact interaction can sometimes be subtle. If you have their number saved, and they have yours saved, you are likely to see their number unless they’ve explicitly hidden it from you as an exception.

Why You Usually CANNOT See Someone’s Phone Number:

Default Privacy: Many users set their “Who can see my phone number” option to “Nobody” or “My Contacts” for enhanced privacy.
>Usernames: Telegram encourages the use telegram number database of usernames on Telegram (send messages, join groups, subscribe to channels) using only usernames, meaning they don’t need to share or display their phone number. If you find someone by their username, you will not see their phone number if they have hidden it.
>No Public Directory: Telegram does not offer a public phone number directory where you can search for someone by name and get their number.

How to Get Someone’s Phone Number on Telegram (Ethical Ways):

Since you generally cannot just “see” someone’s number without their explicit consent, the only ethical ways to get it are:

Ask Them Directly: The simplest and most respectful method. Message them on Telegram (via their username or if they appeared in your contacts) and politely ! ask if can you see someone’s phone number on telegram? they are willing to share their number with you.
>Obtain it Outside of Telegram: If you know them! in real life or through another platform (e.g., email, another social media platform), ask them for their number there.
>Any attempts to bypass! Telegram’s privacy settings clean email to obtain someone’s phone number! are unethical, can violate Telegram’s Terms of Service, and may have legal implications.
