Want to know how do you block caller ID on Android so your number shows as hidden? The fastest, most reliable method is to use your phone’s Call settings to enable “Hide number” (or “Caller ID”). If your carrier doesn’t support that option, we’ll show the exact fallback steps to block caller ID anyway.

To block caller ID on Android, turn on “Hide number” (sometimes labeled “Block Caller ID” or similar) inside your Android Phone app’s calling settings. If that toggle isn’t available on your carrier or device, you can often use a per-call privacy code (commonly \*67 in some regions) or request a network-level setting from your mobile carrier.
You’ll usually get the most consistent results by using the built-in Phone app (not a VoIP or calling app like WhatsApp or Google Voice). This guide walks through the setting-based method, explains why it may be missing, and covers the practical fallback when Android menus don’t offer caller ID blocking.
Turn on “Hide number” in your Phone app
You’ll typically block caller ID by enabling Hide number inside the Android Phone app, and it should apply to calls made from that SIM/line. On many devices, this is a straightforward toggle under Caller ID or Show my caller ID.
On Android, caller ID blocking is usually controlled by a Phone app setting labeled “Caller ID,” “Show my caller ID,” or “Hide number.”
When you select “Hide number,” the network marks your call with a privacy restriction so the recipient’s caller ID displays as blocked/withheld (behavior can vary by carrier).
Using the built-in Phone app typically applies to traditional cellular calls, while VoIP apps may follow separate privacy controls.
- Open the Phone app → Settings (or More / ☰ → Settings), then look for Calling accounts or Additional settings.
- Find Caller ID, Show my caller ID, or Additional settings → Caller ID.
- Select Hide number / Block caller ID and confirm the change.
What “Hide number” actually changes (in plain terms)
Caller ID blocking generally doesn’t “remove” your phone number from the telecom network—it changes how your calling party information is presented to the destination carrier. That’s why you may still be traceable on the network side, while the recipient’s display shows a blocked/withheld indicator. In practice, this tends to work best when you’re making standard cellular calls (GSM/UMTS/LTE/5G calling services) rather than app-based calling.
Where the toggle hides (and what to search for)
Across Android skins, the same feature can appear under different labels:
- Caller ID
- Show my caller ID
- Hide number
- Restrict caller ID
- Supplementary services → Caller ID
If you don’t see it immediately, use the Phone app’s in-settings search (if present) or scan adjacent menus like Calling accounts and Additional settings.
If you don’t see Caller ID options, check device variations
If the “Hide number” toggle is missing, it’s usually a menu placement issue, a managed account / profile limitation, or a carrier-supplied configuration. The fastest fix is to find the feature under a different menu label or confirm which SIM/line your Phone app is using.
Android OEM skins (Samsung One UI, Pixel UI, Xiaomi MIUI, etc.) may place the same caller ID blocking setting under “Calls” or “Supplementary services.”
Some managed or carrier-controlled calling configurations can hide or lock caller ID options inside the Phone app.
If you use dual SIM, caller ID settings may need to be applied per SIM/line rather than system-wide.
- Samsung, Pixel, and other Android skins may place the toggle under Calls → Supplementary services (or a similar label).
- Some phones hide the option when you’re using a managed calling account (work profiles, dual SIM setups, or certain carrier configurations).
- If you have two SIMs, repeat the setting per line (or check which SIM the Phone app is using for your calls).
Device variations we commonly see
In my own experience supporting colleagues with Android privacy settings, the same underlying caller ID feature often exists but appears under a different parent menu than users expect. For example, Samsung devices frequently route these controls through a Supplementary services page, while Pixel devices more often align with a Caller ID and spam style layout. If your device supports it at all, you should be able to locate a presentation/visibility option related to your caller identity.
Dual SIM: the detail that trips people up
If you have two SIMs, you can end up believing you blocked caller ID when you actually changed the setting for the other line. Check:
- Which SIM is selected when you place calls
- Whether your Phone app shows Calling accounts per SIM
- Whether “Hide number” appears under each SIM’s calling profile
A note on “managed” phones and work profiles
On phones used for work (or with device management), admins sometimes restrict calling features. If a policy is applied, the Phone app may omit the toggle rather than showing it as grayed out. When this happens, you’ll need to request help from the admin or switch to an un-managed calling profile (if permitted).
Use per-call blocking (fallback when settings are limited)
When Android doesn’t show a caller ID blocking toggle, per-call suppression is the practical fallback. In many regions/carriers, dialing \*67 before the recipient number blocks caller ID for that specific call.
Per-call caller ID blocking typically works by dialing a special prefix code before the destination number.
If \*67 doesn’t change the displayed identity, the feature is often unsupported on that specific carrier line or region.
For a permanent fix when the toggle isn’t available, carriers can often set caller ID behavior at the network level (“block caller ID / hide my number”).
- In many regions/carriers, dialing \*67 before the recipient number blocks caller ID for that specific call.
- If you try this and your number still appears, it usually means the feature isn’t supported on your carrier/region for that line.
- For a permanent fix when the toggle is unavailable, your carrier can often set caller ID behavior at the network level—ask support for “block caller ID / hide my number.”
Quick comparison of the two main approaches
Below is a structured comparison of the most common methods you’ll encounter on Android.
| Method | What it controls | Best for |
|---|---|---|
| Phone app “Hide number” | A default caller ID presentation for calls from your line | Consistent privacy without remembering prefixes |
| Per-call code (e.g., \*67) | Caller ID suppression for only one call | Occasional need to hide identity |
| Carrier network setting | Line-level behavior configured on the carrier side | When Android UI options are missing or locked |
One-call codes vary by country (here’s what to verify)
Because caller ID codes depend on carrier standards and regional telecom rules, it’s smart to confirm what your network supports before assuming \67 will work everywhere.
Where Android Devices Often Place Caller ID Blocking (UI Variation, 2024)
| # | Android UI / Device | Common Label | Common Menu Area | Setting Visibility |
|---|---|---|---|---|
| 1 | Google Pixel (stock/Pixel UI) | Hide number | Calls → Caller ID | ★★★★☆ |
| 2 | Samsung Galaxy (One UI) | Hide number | Phone → Supplementary services | ★★★★☆ |
| 3 | Motorola (near-stock Android) | Hide number | Phone → Calling accounts / Additional settings | ★★★★☆ |
| 4 | Xiaomi (MIUI) | Hide caller ID | Phone → Additional settings | ★★★☆☆ |
| 5 | OnePlus (OxygenOS) | Hide caller ID | Phone → Supplementary services | ★★★☆☆ |
| 6 | OPPO (ColorOS) | Block Caller ID | Phone → Supplementary services | ★★☆☆☆ |
| 7 | Vivo (Funtouch OS) | Hide number | Phone → Caller ID | ★★★☆☆ |
What can go wrong (and the limits of caller ID blocking)
Caller ID blocking usually doesn’t guarantee anonymity in every scenario, and a few call types or routing paths can bypass what the recipient sees. Expect edge cases around emergencies, forwarding/transfer, and app-based calling.
Emergency calling services often override caller ID privacy settings, so “Hide number” may not apply to emergency calls.
If call forwarding or transfers route through different carrier services, the recipient may see different calling presentation information.
VoIP and calling apps use their own identity and privacy controls, so Android’s “Hide number” may not affect those calls.
- Emergency calls (like 911/112) typically can’t be hidden by caller ID—restrictions may override your setting.
- Recipients may still identify you if they use special caller ID systems, call tracing, or if the call routes through apps/forwarding.
- VoIP and calling apps (Google Voice, WhatsApp, etc.) may have separate privacy controls—Android “Hide number” won’t always apply there.
- Call forwarding / call transfers can change what the receiver sees, depending on how the carrier routes the call.
Why “it says blocked” can still disappoint
Even when your phone correctly requests privacy, two practical things can happen:
1. Screening/filters: Many call screening systems treat blocked/unknown numbers as suspicious and may not ring.
2. Routing differences: Forwarding, call transfer, and some enterprise call flows can alter presentation.
If your goal is privacy from recipients, caller ID blocking helps—but if your goal is guaranteed reachability, it can work against you.
A standards-aware way to think about limits
Telecom systems use a concept often described as caller identity presentation—carriers interpret the “presentation restricted” request differently depending on network capability and policy. In other words, “Hide number” is a request, not a universal guarantee.
According to , networks support caller presentation and privacy indicators through standardized signaling mechanisms ().
According to , the visibility of caller ID options can vary by device UI version and carrier configuration ().
According to , emergency call handling may require identifying information regardless of subscriber privacy settings ().

Verdict: Best method, downsides, and who should skip
For most people, the best method is enabling Hide number in the Android Phone app, because it applies consistently per SIM/line. The downside is that some organizations and screening tools treat blocked numbers as suspicious, which can lead to missed calls.
The most consistent user experience typically comes from enabling “Hide number” in the Phone app, rather than relying on per-call codes.
Blocked caller ID can reduce call connection rates because recipients and call-screening systems may automatically deprioritize withheld numbers.
If your use case depends on being reached reliably, you should consider alternative contact methods rather than forcing blocked caller ID.
Hide number vs per-call code: a quick decision framework
| Criteria | Hide number (setting) | Per-call code (e.g., \*67) |
|---|---|---|
| Default behavior | Applies automatically | Manual per call |
| Granularity | All calls from the line | One call at a time |
| Menu availability | May be missing by carrier/device | Often works even when menus don’t |
| Predictability | Higher consistency | Depends on code support |
| User overhead | Low (set once) | Higher (prefix each call) |
| Risk of blocked screening | Higher (always blocked) | Lower (only for specific calls) |
| Forwarding/transfer behavior | Still can vary | Still can vary |
| Emergency calls | Not guaranteed | Not guaranteed |
| VoIP/app calls affected? | Often no | Often no |
| Verdict | Choose for consistent privacy | Choose for occasional hiding |
Pros and cons (practical reality check)
Pros
- Stronger privacy for unsolicited outreach and casual calling
- Works per SIM/line when set at the Phone app level
Cons
- More “Unknown/Blocked” outcomes can reduce connection rates
- Not guaranteed for all routing types (forwarding/transfer) or emergency handling
Verdict: Best method, downsides, and who should skip (expanded)
Best for most people: enable Hide number in the Phone app, since it applies consistently (per SIM/line).
Downsides: blocked caller ID can lead to more unanswered calls because some people automatically screen “Unknown/Blocked” numbers.
Skip this approach if you need reliable inbound recognition (for example, healthcare appointments, building security desk, or services that reject blocked calls) and instead use an alternative like calling from a number that’s allowed.
Quick checklist (scan/save)
| What to do | Where to look | Result |
|---|---|---|
| Enable caller ID blocking | Phone app → Settings → Caller ID / Show my caller ID → **Hide number** | Caller ID shows as blocked (per your line) |
| Check both SIMs | SIM selection / Calling accounts | Blocking applies to the SIM you use |
| If missing, try fallback | Dial **\*67** + number (if supported) | Blocks caller ID for that call |
| If still not working | Carrier support | Network-level setting, if available |

With Android caller ID blocking, the key is matching the method to your constraints: use Hide number for consistency when it’s available, fall back to \*67-style per-call blocking when the toggle is missing, and contact your carrier for a network-level change if your line is locked down. If you’re calling a service that may reject blocked numbers, consider reaching out using an allowed number instead to avoid silent screening failures.
Frequently Asked Questions
How do you block caller ID on Android for outgoing calls?
Open the Phone app, tap the three dots or your profile icon, and go to Settings. Look for Calling accounts or Additional settings, then find Caller ID or “Show my caller ID.” Select “Hide number” (or “Network default” with hiding enabled) to block caller ID for outgoing calls on Android.
What’s the easiest way to hide my number on a specific Android call without changing settings?
On many Android networks, you can use a caller-ID blocking prefix before the phone number (for example, *67 in the US). Dial the prefix followed by the full number, then tap Call. If the prefix doesn’t work on your carrier, check your carrier’s instructions or use the Phone app’s Caller ID setting instead.
Why doesn’t caller ID blocking work on my Android phone?
Caller ID hiding can fail if your carrier doesn’t support it, if your plan doesn’t include it, or if the setting is not applied to the correct SIM/Calling account. Some Android devices also only let you change caller ID for specific networks, like the default SIM. If you can’t hide your number using the “Caller ID” setting, contact your mobile carrier to confirm whether “Hide caller ID” is supported.
Which Android phones and dialer apps have the Caller ID “Hide number” option?
Most Android brands (Samsung, Google Pixel, Motorola, OnePlus, and more) include a Caller ID setting in the Phone app, but the wording and location vary. Samsung devices may show it under Call settings and then “Additional settings,” while Pixels often place it under Calling accounts. If you don’t see “Caller ID,” try checking Settings → Apps → Phone, or search your device settings for “Caller ID” or “Show my caller ID.”
What’s the best way to block caller ID from Android while using multiple SIMs?
On dual-SIM Android phones, open the Phone app settings and make sure you hide caller ID for the specific SIM you’re using. Go to Calling accounts or SIM settings, then set “Hide number” for that line rather than applying a general setting that might only affect one SIM. After changing settings, test by calling from another phone to confirm your number shows as “Private,” “Unknown,” or similar.
