Company-Owned SIM Card: If a virtual number isn't feasible, use a dedicated, company-owned physical SIM card (e.g., a spare corporate mobile line) that is solely for the Telegram business account. This SIM should be stored securely and managed by a responsible team member.
2. Strict Phone Number Privacy Settings
For any business account on Telegram, configure the privacy settings to their maximum:
This ensures that your business's contact number is never displayed on its Telegram profile, protecting it from being scraped or collected by unauthorized parties.
"Who can find me by my number?": Set telegram number database to "Nobody".
Even if someone obtains the business's dedicated phone number, they won't be able to find the Telegram profile by searching for the number directly within the app.
Utilize a Prominent Username:
Ensure your business account has a clear, easily searchable username (e.g., @YourCompanyNameOfficial). This is the primary way clients should find and contact your business on Telegram.
3. Robust Account Security Measures
The phone number is the primary access point, so its security is paramount:
Mandatory Two-Step Verification (2FA) with a Strong Password:
This is the single most critical security measure. Set a complex, unique 2FA password for the business Telegram account.
Crucial Email Recovery: Link a secure, dedicated business email address to the 2FA for password recovery. This email account itself must also be highly secured with 2FA.
Regular Review: Periodically review and potentially update the 2FA password and recovery email.
