How to Hide Number & Manage Caller ID on iPhone, Android
In today’s smartphone era, privacy and call management have become more important than ever. Many users prefer to keep their number hidden during certain calls—whether for professional reasons, safety concerns, or simply to avoid unwanted callbacks. The good news is that you no longer need to rely on complicated codes or third-party tools in every case. Both iPhone and Android platforms now provide built-in options to hide Caller ID. In addition, some countries offer carrier-level settings and traditional dialing prefixes for the same purpose. This report provides a detailed step-by-step guide for users in the United States, Canada, India, and the United Kingdom—along with useful alternatives and precautions.
For iPhone Users: Hide Number Directly from Settings
On iPhone, hiding your number is relatively straightforward. Open Settings → Phone → Show My Caller ID, and toggle it off. Once enabled, your outgoing calls will no longer display your number to the receiver. However, some carriers control this feature. If the “Show My Caller ID” option is missing from your iPhone, it usually means that your carrier has restricted the feature or your plan doesn’t support it. In such cases, contacting carrier support or using a temporary prefix before dialing can be the solution.
It is also important to note that many receivers use features like “Silence Unknown Callers.” This means even if you hide your number, the call may go directly to voicemail or appear as a missed call. For important communications, it is wise to inform the recipient in advance or keep an alternative method ready.
For Android Users: Menus Differ by Brand, But the Feature Is the Same
On Android, the option to hide Caller ID may vary slightly depending on the brand and interface, but the path is similar: Phone app → Settings → Calling accounts/SIMs → Select SIM → Additional/Advanced settings → Caller ID → Hide number. Some phones may list it under Caller ID & spam settings. If “Hide number” is unavailable, it may be due to carrier restrictions. In such cases, you can either use temporary prefix codes or request a permanent block through your carrier.
One added benefit of Android is the Google Phone app, which includes advanced Caller ID & spam protection. This helps identify and filter spam or unknown calls—very useful for users frequently troubled by telemarketing calls.
Google Voice and Virtual Numbers
In the United States, services like Google Voice are widely used. The app provides a virtual number and allows users to hide Caller ID by enabling Menu → Settings → Calls → Anonymous Caller ID. However, availability varies by country, and effectiveness may depend on carrier interoperability. Still, for professionals, having a separate number for call history, voicemail, and client communication makes Google Voice an attractive option.
Other apps like Burner, Hushed, Skype Number, and TextNow also provide virtual numbers. While many of these are paid services, they offer improved privacy, independent call logs, and additional spam protection. Since Google Voice has limited availability in India and the UK, alternatives like Skype Number or Hushed/TextNow are more practical there.
Temporary Hiding for One Call
Not every user wants to block Caller ID permanently. For single calls, traditional prefix codes remain effective.
- United States & Canada: Dial *67 before the number to hide Caller ID.
- United Kingdom: Use 141 before the number.
- India: Temporary prefixes are not universally supported; many carriers don’t offer this option. Indian users are better off relying on phone settings, carrier options, or virtual number services.
Remember, if the recipient has blocked unknown callers, your hidden call may be automatically rejected or sent to voicemail.
Carrier-Level Caller ID Blocking
In several countries, carriers allow Permanent Caller ID Block at the account or line level.
- United States & Canada: Customers can request this via support or account portals. To override for a single call, dial *82 before the number.
- United Kingdom: Major providers (O2, EE, Vodafone, Three) allow permanent or temporary blocking, with codes like 1470 sometimes available to unblock Caller ID for one call.
- India: This option is limited for regular users, though it may be available on corporate circuits or cloud telephony services.
Country-Specific Guide
United States: iPhone and Android Caller ID settings generally work on most carriers. *67 is widely supported for temporary hiding, while *82 reveals the number if your line is set to block by default. For spam prevention, carrier solutions like AT&T ActiveArmor, Verizon Call Filter, T-Mobile Scam Shield are popular—alongside apps like Hiya, RoboKiller, Nomorobo, and Truecaller.
Canada: Works much like the US. *67 is supported across major carriers like Bell, Rogers, and Telus. These providers also offer privacy settings through accounts. Spam filtering can be managed with the Google Phone app and third-party apps.
India: Caller ID hiding depends heavily on the carrier. Many users may not see the option on their phones. Temporary prefixes are unreliable, so services like Skype Number, Hushed, TextNow, or enterprise cloud telephony are better alternatives. For spam protection, TRAI DND registration, Google Phone spam filter, Truecaller, Hiya, and iPhone’s Silence Unknown Callers are effective.
United Kingdom: Caller ID hiding is generally supported. Dialing 141 before a number hides it temporarily. Carriers also provide account-level blocking. For spam prevention, users can combine network features with apps like Truecaller and Hiya for better results.
Protection Against Spam Calls
On iPhone: Go to Settings → Phone → Silence Unknown Callers to send unknown calls directly to voicemail. Under Call Blocking & Identification, apps like Hiya, Truecaller, RoboKiller, Nomorobo, and carrier-provided filters can be activated.
On Android: The Google Phone app provides options under Caller ID & spam → Filter spam calls. Some brands also integrate Hiya or Smart Call directly into their dialers. These tools can identify suspicious numbers and block or warn users, reducing call disturbances significantly.
Legal and Practical Precautions
Caller ID hiding is a legitimate privacy feature but must be used responsibly. Using it for harassment, fraud, or spoofing is illegal. Also, emergency services (such as 911, 112, 100, or 999) will always display your number for safety reasons. Some businesses, banks, and toll-free lines may reject anonymous calls altogether. Therefore, in sensitive situations, it’s better to disclose your number or use official communication channels.
Conclusion
Both iPhone and Android offer simple ways to hide your number. Where available, temporary prefixes like 67 (US/Canada) or 141 (UK) are practical options. In India, where restrictions are common, virtual number services and built-in spam filters prove more effective. To protect against spam, it’s best to combine device features with reliable third-party apps. Most importantly, Caller ID hiding should be used responsibly—helping you maintain privacy while ensuring communication remains safe and secure.
