Frequently Asked Questions

Create or verify the public username, copy its official https://t.me/username link, encode that URL, and test it in both Telegram and a signed-out browser before printing. Keep the visible account name beside the code so the reader knows which profile or organization should open.

A public username link lets people contact you without knowing the number, subject to Telegram privacy settings. A phone-number t.me link exposes the number and works only when find-by-number settings permit it. Behavior can differ by operating-system version, camera app, permissions, and installed apps, so test representative devices.

No. It can open a public group or invite link, but the viewer must follow Telegram's join or request flow and may need administrator approval. A stable profile or landing-page URL is safer for print than a temporary post, invitation, or session-specific link.

Anyone who photographs or decodes it may be able to reuse or share the invite. Control its placement, monitor membership, use approval or limits where available, and revoke leaked links. Keep the visible account name beside the code so the reader knows which profile or organization should open.

The static symbol does not expire, but its username can change, an invite can be revoked or limited, a post can be deleted, or a bot or group can become unavailable. The symbol may remain decodable while its website, domain, account, file permission, or redirect stops working.
