Receiving calls from unknown numbers can be unsettling, especially when deciding whether to return the call. While some calls may be legitimate, others could be from telemarketers or scammers. Here's how to assess whether it's safe to return a call from an unknown number.
What Does 'No Caller ID' Mean?
When your phone displays "No Caller ID," it indicates that the caller has intentionally hidden their number. This is often achieved by dialing a code like *67 before the number, which prevents your phone from receiving the caller's information. Consequently, there's no way to call back directly, as your device doesn't have the number. (slashgear.com)
How to Identify Unknown Callers
If you receive a call from an unknown number and wish to identify the caller before returning the call, consider the following methods:
-
Use Call Return Services: In the U.S., dialing *69 immediately after receiving a call can provide the number of the last incoming call. However, this service may be chargeable and is not always effective for calls from hidden numbers. (makeuseof.com)
-
Search the Number Online: Enter the unknown number into a search engine to see if it's associated with any known businesses or reported scams. Websites like Whitepages and ZLookup offer reverse phone lookup services that can provide information about the caller. (makeuseof.com)
-
Use Caller Identification Apps: Apps such as Truecaller and Hiya can help identify unknown callers by cross-referencing the number with their databases. These apps can also block known spam numbers. (guidingtech.com)
When Should You Return a Call from an Unknown Number?
Before returning a call from an unknown number, consider the following:
-
Missed Call with One Ring: If you notice a missed call with only one ring, it could be a scam attempt to get you to call back, potentially leading to high charges. (mytour.vn)
-
Voicemail Left: If the caller left a voicemail, listen to it carefully. Legitimate callers often leave a message explaining the purpose of their call.
-
Known Contacts: If the number is from someone you know but not saved in your contacts, consider returning the call.
How to Protect Yourself from Unwanted Calls
To minimize the risk of unwanted or scam calls:
-
Block Unknown Callers: Both iPhone and Android devices offer features to block calls from unknown numbers. On iPhone, you can enable "Silence Unknown Callers" in the settings. On Android, the steps vary by manufacturer but generally include options to block calls without a number in the phone app settings. (slashgear.com)
-
Use Call Screening Features: iOS 26 introduced a "Call Screening" feature that prompts unknown callers to state their name and reason for calling before your phone rings. This allows you to decide whether to accept or decline the call based on the transcribed message. (techradar.com)
-
Register with the National Do Not Call Registry: Adding your number to the National Do Not Call Registry can reduce the number of unsolicited calls you receive.
Conclusion
Deciding whether to return a call from an unknown number requires caution. By utilizing available tools and features, you can make informed decisions and protect yourself from potential scams.
