How to Make Anonymous Calls: *67, Hide Caller ID & More (2026)
Learn how to hide your phone number when calling. Complete guide to *67 code, iPhone/Android caller ID settings, Verizon/AT&T/T-Mobile methods, second number apps, and legal rules.
Want to hide your phone number when calling? The fastest method is dialing *67 before the number — the recipient sees "Blocked" or "Private" instead of your caller ID. But *67 isn't the only option, and it doesn't work in every situation.
This guide covers every method to make anonymous calls in 2026: the classic *67 code, permanent settings on iPhone and Android, carrier-specific options for Verizon, AT&T, and T-Mobile, VoIP and second-number apps, and important limitations you should know.
Quick Overview: How to Hide Your Number
1. *67 (per-call): Dial *67 + the phone number. Works immediately on all carriers.
2. iPhone Setting: Settings → Phone → Show My Caller ID → toggle OFF.
3. Android Setting: Phone app → ⋮ → Settings → Caller ID → Hide number.
4. Second Number App: Use Google Voice, Burner, or Hushed for a separate anonymous number.
5. VoIP Service: Use BubblyPhone or similar VoIP to call without revealing your personal number.
Method 1: Dial *67 Before the Number
The *67 code is the fastest way to hide your number for a single call. It's been part of the US phone system since the 1960s, developed by Bell System as a CLASS code. It works on every major carrier and requires no setup.
How to use: Dial *67 + phone number → Call. Example: *67-555-123-4567 — recipient sees "Blocked" or "Private".
Works for: All mobile phone calls, landlines, Verizon/AT&T/T-Mobile, regular phone numbers.
Does NOT work for: Toll-free numbers (800/888/877), 911 emergency calls, text messages, some business unmasking systems.
Carrier note: AT&T users may need to dial *67# (with #). Verizon and T-Mobile use standard *67.
Method 2: Hide Your Number on iPhone (Permanently)
Step 1: Open Settings. Step 2: Tap Phone. Step 3: Tap Show My Caller ID. Step 4: Toggle OFF.
If "Show My Caller ID" doesn't appear, your carrier may not support this feature. T-Mobile does not offer permanent caller ID hiding — use *67 per-call instead.
Method 3: Hide Your Number on Android (Permanently)
Step 1: Open Phone app. Step 2: Tap ⋮ (three dots). Step 3: Settings. Step 4: Calling accounts or Supplementary services. Step 5: Caller ID. Step 6: Hide number.
| Phone Brand | Settings Path |
|---|---|
| Samsung Galaxy | Phone → ⋮ → Settings → Supplementary services → Show caller ID → Hide |
| Google Pixel | Phone → ⋮ → Settings → Calls → Additional settings → Caller ID → Hide |
| Other Android | Search "Caller ID" in main Settings app |
Carrier-Specific Methods
| Carrier | Per-Call Code | Permanent Option |
|---|---|---|
| Verizon | *67 | Yes — My Verizon app |
| AT&T | *67# | Yes — call customer support |
| T-Mobile | *67 | No — per-call only |
| Google Voice | *67 | Yes — Settings → Caller ID |
To unblock for one call when permanent blocking is enabled, dial *82 before the number.
Method 4: Second Number and VoIP Apps
A second phone number provides stronger privacy than *67. The recipient sees a real number — just not your number.
| App | Cost | Best For |
|---|---|---|
| BubblyPhone | From $0.01/min | International calls without revealing your number |
| Google Voice | Free (US) | Free US calling with separate number |
| Burner | From $4.99/mo | Temporary/disposable numbers |
| Hushed | From $3.99/mo | 300+ area codes, US/UK/Canada |
When You Cannot Hide Your Number
911 Emergency Calls: Emergency services always see your real number and location. Required by law.
Toll-Free Numbers (800/888/877/866/855/844/833): Businesses paying for incoming calls have the right to see who's calling. *67 is stripped automatically.
Law Enforcement Subpoenas: Your carrier always has a record. Courts can compel carriers to reveal identity.
Text Messages: *67 only works for voice calls. SMS always shows your number. Use a second-number app for anonymous texting.
Is Anonymous Calling Legal?
Yes — hiding your real phone number is completely legal in the US. The Truth in Caller ID Act of 2009 targets transmitting false caller ID with intent to defraud or harm. Simply blocking your number via *67 or carrier settings is not affected. Penalties for illegal spoofing: up to $10,000 per violation.
