Privacy Calling — Head-to-Head

*67 vs Virtual Phone Numbers: Which Is Better for Privacy in 2026?

Both methods hide your number — but in completely different ways. *67 shows "Unknown" and increasingly gets blocked. Virtual numbers show a real (but different) caller ID that actually gets answered. Here's when to use each.

Quick Answer

Use *67 for a quick free anonymous call where you don't mind if it goes unanswered. Use a virtual number (Voizly) when the call must be answered — it shows a real caller ID, works internationally, and is still private because it's not your number.

How *67 Works — and Why It's Less Effective in 2026

*67 (or Caller ID Block) is a carrier-level feature that instructs your phone company to suppress your number on outgoing calls. When you dial *67 + number, the PSTN (Public Switched Telephone Network) signals the recipient's carrier to display "Unknown" or "Private Number" instead of your digits.

This worked well for two decades. The problem in 2026: smartphones have become aggressive about blocking anonymous calls.

Why *67 Fails More Often in 2026

  • → Apple: "Silence Unknown Callers" is now on by default on many iPhones — all Unknown calls go directly to voicemail
  • → Android: Google Phone app screens all Unknown calls and may auto-decline them
  • → Carriers: AT&T, Verizon, and T-Mobile have "Call Filter" features that flag Private Number calls as potential spam
  • → India: *67 doesn't apply for international calls — TRAI regulations govern caller ID separately

The result: a significant portion of *67 calls in 2026 never ring. The recipient's phone silently routes them to voicemail — or their carrier intercepts the call entirely.

How Virtual Numbers Work — and Why They Get Answered

A virtual phone number is a number that exists in a VoIP provider's system — not tied to any physical SIM. When you call through Voizly, your call is routed through Voizly's infrastructure and the recipient's phone displays the virtual number — a real, dialable phone number (though not your personal one).

From the recipient's perspective, the call looks exactly like any normal incoming call. Their phone rings normally. No "Unknown" tag. No spam filter. Just a number in whatever country format Voizly assigned.

  • · Quick, one-off US/Canada domestic call

Legal Note

Both *67 and virtual numbers are legal in most countries for legitimate privacy use. Using either method for harassment, fraud, or impersonation is illegal. In the US, the Truth in Caller ID Act prohibits using any caller ID spoofing technique to defraud or harm. Voizly and legitimate VoIP services are PSTN-compliant and not spoofing tools.

Frequently Asked Questions

Is *67 still effective in 2026?
*67 still technically works — it blocks your number from appearing on the recipient's caller ID. But its effectiveness has declined because most modern smartphones (iPhone's Silence Unknown Callers, Google Pixel's call screening) automatically send 'Unknown' calls to voicemail. Your call may never ring through.
What is a virtual phone number?
A virtual phone number is a phone number not tied to a specific SIM card or physical phone line. VoIP services like Voizly assign a virtual number to your outgoing calls — the recipient sees this number instead of your real one. Unlike *67, the number appears as a real, callable number.
Can you use *67 for international calls?
*67 only works for calls within the USA and Canada. For international calls (e.g., from the US to India, or from the UAE to India), *67 does not apply. To make international private calls, you need a VoIP app with virtual number support, such as Voizly.
Do virtual numbers work for international calling?
Yes. Voizly's virtual number system works for international calls to India, USA, UK, Germany, and France at $0.04/min (India/USA/UK) or $0.08/min (Germany/France). No SIM card required — your personal number is protected and the recipient sees a legitimate caller ID.
Why do people use *67?
People use *67 to hide their personal number when calling strangers — for Craigslist or Facebook Marketplace transactions, contacting an ex, calling a business without revealing your private number, or following up on job applications. In 2026, a virtual number (VoIP) is usually a better option because the call shows as a real number and gets answered.
