Virtual numbers create a barrier between your real identity and online services. When you use a SMS-Bus temporary number for verification, the service only gets the virtual number — not your personal one. This prevents: (1) Companies from linking your phone to marketing databases, (2) Data breaches from exposing your real number, (3) Unwanted calls and SMS spam, (4) Cross-platform tracking through your phone number.
Yes, phone numbers are powerful tracking identifiers. Companies can: (1) Link your accounts across platforms using the same phone number, (2) Build profiles from data breaches containing your number, (3) Send targeted ads based on your number, (4) Sell your number to data brokers. Using virtual numbers from SMS-Bus prevents this by ensuring different services get different numbers, none of which are linked to your identity.
For maximum privacy, yes — use a different temporary number for each service. Practically, here is a good strategy: Use your real number for essential services (banking, primary email, government). Use temporary numbers for: social media experiments, free trials, one-time purchases, services you are testing, and anything you might not continue using. SMS-Bus makes this easy with numbers from 20+ countries.
Sharing your phone number puts several things at risk: (1) Identity — your number can be used in social engineering attacks, (2) Location — phone numbers can reveal your general location, (3) Privacy — data brokers compile profiles linked to phone numbers, (4) Security — SIM swap attacks target phone numbers for account takeover, (5) Spam — your number can be sold to telemarketers. Using virtual numbers eliminates these risks for non-essential services.
SMS-Bus offers free shared virtual numbers, while paid services provide dedicated private numbers. Key differences: SMS-Bus is free (paid services cost $1-10/month per number), SMS-Bus numbers are shared (paid numbers are private), SMS-Bus is for temporary use (paid numbers can be permanent). Choose SMS-Bus for one-time verifications and testing. Choose paid services for accounts you want to keep long-term with a consistent private number.
While technically possible, using shared virtual numbers from SMS-Bus for ongoing 2FA is not recommended. Since numbers are shared and may be rotated, you could lose access to future codes. For 2FA, better options include: (1) Authenticator apps (Google Authenticator, Authy), (2) Hardware security keys (YubiKey), (3) A paid private virtual number, (4) Your real phone number for critical accounts.
