How to hide caller id on samsung with device settings
Using the phone app settings menu
The built-in Phone app on Samsung devices often includes a direct option to hide caller ID for individual calls. This method works for most Galaxy smartphones running One UI based on Android 10 or later.
To access it, open the Phone app, tap the three dots or More options, and look for a Calling or Supplementary Services section. The exact path may vary slightly depending on your firmware and carrier.
Checking for carrier restrictions
Some carriers manage caller ID at the network level, which can limit what the device settings alone can change. Before troubleshooting, confirm with your carrier whether line blocking is supported in your area.
If your carrier requires a special code or subscription, using device settings may not be enough, and you might need to contact support or enable line hiding via USSD.\p>
Hide caller id on samsung using ussd codes
Entering the line blocking code
USSD codes provide a quick way to control caller ID without installing extra apps. The most common code for temporary hiding on many networks is *67, but this depends on your region and carrier.
Dial *67 before the number you want to call, then press Call. This usually hides your number for a single call, and the recipient sees either "Private," "Unknown," or a similar label.
Permanent or subscription-based options
For a longer lasting solution, some carriers offer line blocking services that you enable by dialing a specific code, often *67 or a proprietary number provided in your plan documents.
If you subscribe to a privacy or call management service, the provider may use a different code, so check your account dashboard or contact support for the exact sequence.
Alternative methods and third party apps
Using default Samsung call settings
Samsung's One UI sometimes adds caller ID controls within the Calls or Connections menu. Go to Settings, search for Calls, and look for Line Visibility, Caller ID, or Privacy options.
These settings may allow you to set a default behavior, such as always hiding your number when dialing outside your network or limiting visibility to saved contacts only.
Testing with a second device
Before making important calls, test your setup by calling a trusted second number or asking a friend to check how your ID appears.
This simple step ensures that your chosen method, whether via settings or USSD, actually works as expected on your device and with your current carrier plan.

How hide caller id on samsung works under the hood
Network signaling and identification
When you place a call, your device sends a signaling packet that includes your Mobile Station International Subscriber Directory Number, or MSISDN. Hiding caller ID modifies or suppresses this field so the network does not share your number.
Some carriers treat line hiding as a value added service, while others rely on standard Supplementary Services codes defined in GSM or LTE specifications.
Impact on call completion and reliability
Most calls complete normally when your ID is hidden, but some recipients may decline private numbers due to security policies. If a call fails repeatedly, check whether your carrier blocks certain services or if your account has restrictions.
Turning off line hiding during critical business calls can improve trust and answer rates, especially when reaching new customers or institutions.
Key takeaways for managing caller ID on Samsung devices
- Use the Phone app settings for flexible, per call control when supported.
- Try *67 for quick, temporary hiding if your carrier allows it.
- Review carrier plans and policies for permanent line blocking options.
- Test your setup with a trusted contact to confirm the ID appears as intended.
- Remember that some organizations may reject private numbers, affecting call success.
FAQ
Reader questions
Will *67 really hide my caller ID on a Samsung phone?
Yes, dialing *67 before a number usually hides your ID for that call on most networks. Check with your carrier to confirm support and any possible restrictions based on your plan.
Can I hide my caller ID for all outgoing calls without changing calls each time?
Yes, you can often set a default in your Samsung device settings or enable a carrier line blocking service. This makes your number appear as private by default, depending on your region and provider policies.
Why does the recipient sometimes see my number even when I hide it?
This can happen if the carrier overrides line hiding, the recipient's service strips private IDs, or your account has a special configuration. Testing with a second number helps identify where the exposure occurs.
Is hiding caller ID free, or could it result in extra charges?
Using codes like *67 is typically free, while carrier subscription services may have monthly fees. Verify pricing details with your provider to avoid unexpected charges on your bill.
