How to no caller ID on iPhone means hiding your phone number from the person you call, either for every outgoing call or just one call at a time. The exact method depends on your carrier, and hiding caller ID does not make the call anonymous to the network.
Use the steps below to choose the right option, understand what the recipient sees, and avoid common situations where caller ID blocking does not work
1. What ‘No Caller ID’ Actually Means
Using caller ID suppression prevents your phone number from appearing on the recipient’s caller ID display. Depending on their phone and carrier, they may see No Caller ID, Private, Anonymous, or a similar label instead of your number.
That is what using no caller ID on iPhone actually changes: the number is hidden from the person receiving the call.
It does not make the call untraceable at the network level. Your carrier still processes the call and keeps network records associated with it. Caller ID blocking also does not apply universally to every destination. Major US carriers state that caller ID cannot be blocked for emergency calls such as 911 or for certain toll-free numbers.
2. How to Get No Caller ID for All Outgoing Calls
On current iPhones, Apple lets you hide your caller ID for outgoing calls if your carrier supports the feature.
- Open Settings.
- Tap Apps.
- Tap Phone.
- Tap Show My Caller ID.
- Turn the toggle off.
When this setting is off, people you call will not see your phone number on supported calls. Apple notes that if Show My Caller ID is dimmed or does not appear, you should contact your carrier because the feature may not be available on your account or network.
The setting stays in effect until you turn it back on.

3. Hide Your Number for a Single Call
If you only want no caller ID on iPhone for one call, many US carriers support the *67 prefix.
Open the Phone app, enter *67 followed by the 10-digit number, then place the call.
For example: *67 555-867-5309
On supported networks, the recipient sees a label such as Private or Anonymous instead of your number. Many carriers document *67 for one-call caller ID blocking.
This does not change your permanent caller ID setting, so your next normal call will display your number again.
Keep in mind that *67 is carrier- and country-dependent. It should not be treated as a universal international code, and some numbers, including 911 and certain toll-free lines, may still receive your caller information.
Some carriers also support codes that temporarily show caller ID when permanent blocking is enabled, but these codes are carrier-specific. Check with your provider rather than assuming *82 works everywhere.
4. Why This Doesn’t Work the Same Way for Texts
How to no caller ID on iPhone applies to voice calls, not text messages.
Turning off Show My Caller ID or using *67 does not hide your number when sending SMS or iMessage. Those services use their own sender identity, so there is no iPhone setting that makes a normal SMS or iMessage arrive as “No Caller ID.”
If you want to communicate without sharing your main phone number, you need a different service rather than caller ID blocking.
For example, some secondary-number services provide a separate number for calls and texts. Signal also offers phone-number privacy controls and usernames that can let people connect without your number being visible in the chat, depending on your privacy settings.
That is different from making a normal iPhone text anonymous.
5. What the Recipient Sees
When how to no caller ID on iPhone is successfull, the exact message shown on the recipient’s phone varies.
They may see:
- No Caller ID
- Private
- Anonymous
- Unknown
The caller does not choose which label appears. It depends on the receiving carrier and device.
The recipient generally cannot tap the label to reveal the hidden number from the normal call screen. However, that does not mean the call is anonymous to the telecommunications network.
Another practical issue is call filtering. On iPhone, people can use settings that screen or silence calls from unknown callers. If your number is hidden, your call may therefore be silenced or sent to voicemail instead of ringing normally.
6. If Show My Caller ID Is Missing or Grayed Out
If following the how to no caller ID on iPhone but Show My Caller ID does not appear or cannot be changed, the most likely explanation is carrier support.
Apple specifically says that if the option is dimmed or missing, you should contact your carrier.
The carrier may:
- Not support caller ID blocking on that line
- Control the feature at the account level
- Require you to enable or disable caller ID through its app, website, or customer support
For example, some carriers let customers manage caller ID blocking directly through their account settings rather than only through the iPhone interface. Many carriers document account-level caller ID blocking options in addition to per-call blocking.
If the option was previously available and suddenly disappears, you can also restart the iPhone and make sure iOS is up to date, but the carrier remains the best source for confirming whether the feature is active on your line.
7. FAQs
Does *67 Still Work on iPhone?
Yes, with many US carriers, *67 can still work for hiding caller ID on a single call. It does not work for every destination, including certain emergency and toll-free numbers.
Can Businesses Still See My Number Even if It’s Hidden?
Usually not through ordinary caller ID if the carrier successfully blocks your number. However, your carrier still has network records of the call, and some special services or destinations may receive caller information despite suppression.
Does This Work for International Calls?
Not reliably with *67. Caller ID blocking codes vary by country and carrier, so check with your provider before making an international call if you need your number hidden.
Can Someone Trace a ‘No Caller ID’ Call Back to Me?
The call is still recorded by the telecommunications network even though the recipient does not see your number. A regular recipient cannot normally reveal it from the iPhone call screen, but carriers can retain records and may provide them when legally required.
Conclusion
Hiding your number on iPhone is simple once you know whether you want the setting to apply to one call or all outgoing calls. For how to no caller ID on iPhone, the built-in caller ID setting and carrier-supported codes like *67 cover most situations.
The main thing to remember is that this protects what appears on the other person’s screen, not your identity from the carrier itself.
