Most of us receive calls from unknown or unidentified numbers on a regular basis. While some of these may be legitimate calls from businesses or acquaintances, others could be spam or scam calls. As an iPhone user, there are several ways for you to find out who an unknown caller number is before choosing to answer or ignore their call.
In this comprehensive guide, we will explore the top techniques to identify anonymous callers on an iPhone.
What is a Unknown Caller Number
An unknown caller number refers to a phone number that shows up on your caller ID but is not recognized because it is not stored in your contacts. Some key characteristics of unknown caller numbers:
- The number appears as “Unknown”, “Private”, or “Anonymous” on the incoming call screen. No caller name or details are displayed.
- The actual phone number is hidden or blocked from being shown. This is often done intentionally by the caller.
- You do not have the number saved in your phone’s contacts, so there is no name or photo associated with it.
- Answering or returning a call from an unknown number carries a greater risk as you cannot verify the caller’s identity.
- Unknown callers can include legitimate calls from businesses or acquaintances but also more unwanted calls like telemarketers, scammers, robocalls etc.
- On iPhones, Apple’s software hides the underlying phone number from initial view but it still gets logged in your recent call history.
- There are various techniques to try to identify an unknown caller number after the fact through reverse phone lookups, carrier records, voicemail messages, and blocking repeat callers.
An unknown caller number is a phone number that your device cannot match to an existing contact when receiving an incoming call, resulting in limited caller information being displayed.
Is it Possible to Find Out an Unknown Caller Number on iPhone
Yes, it is possible to find out an unknown or blocked caller’s number on an iPhone using various methods:
- Check your call history – Even if it said “private” or “unknown”, the full number may be listed in your recent calls.
- Use a reverse phone lookup service by entering the number to identify the caller.
- Enable call announcing in iPhone settings to speak the caller’s name or number.
- Download a call blocking app like Truecaller that can ID unknown numbers.
- Contact your carrier and ask them to trace the source of anonymous calls.
- Let unknown calls go to voicemail – callers may leave a callback number.
- Block the number to prevent further calls from that source.
- Search the number online to see if others have reported it.
- Report chronic unknown callers to the FCC for investigation.
While iPhone will hide numbers initially, there are ways to uncover most anonymous callers through call history, apps, carrier assistance, and avoiding answering the call. Persistence helps reveal unknown sources.
How Unknown Caller Number on iPhone Works
Here is a brief overview of how unknown caller numbers work on an iPhone:
- When someone calls you from a number not stored in your contacts, iPhone will display “Unknown” or “Private Number” instead of the actual phone number.
- This is done to protect the caller’s privacy and prevent unwanted calls if the number was displayed.
- However, the full phone number is still transmitted to your iPhone when the call comes in.
- iPhone will record the number in your call history/recents log, even if it doesn’t display it on the incoming call screen.
- You can view the full number later in the call history and use it to identify the caller through reverse lookup services or your carrier.
- Some apps like Truecaller can also identify unknown numbers using crowd-sourced databases when the call comes in.
- Allowing unknown calls to go to voicemail often results in the caller leaving their real number for callback.
- Reporting chronic unknown callers can help carriers and law enforcement trace harassing calls if needed.
So while iPhone won’t display it, the unknown caller’s number can usually be retrieved through call logs, carrier records, and other methods for identification after the fact.
How to Find Out an Unknown Caller Number on an iPhone (Easy Methods)
Here is a summary on how to find out an unknown caller number on an iPhone:
Though iPhone displays “Unknown” or “Private” for unidentified numbers, there are several ways to uncover the source:
- Check your call history/recents log for the full number, even if it only showed “No Caller ID” at first.
- Use reverse phone lookup services by entering the unknown number to identify the caller.
- Enable iPhone’s call announcing feature to speak a caller’s name or number.
- Download apps like Truecaller that can ID unknown callers using crowd-sourced databases.
- Contact your carrier and ask them to trace the source of any anonymous calls.
- Let unknown calls go to voicemail, as callers often leave identifying details in messages.
- Block repeated unknown numbers to prevent further calls from that source.
- Search the number online to see if others have reported or discussed it.
- Report chronic unknown callers to the FCC for investigation into illegal calling.
While iPhone hides numbers initially, persistence using call logs, carrier records, apps, and avoiding answering can uncover most anonymous callers.
Method 1: Use Your iPhone’s Built-in Tools
The iPhone has some useful built-in tools to help identify unknown numbers. Here are a few ways to use them:
1. Check Recent Calls List
After receiving a call from an unknown number, open the Phone app and select the Recents tab. This will show a list of all recent incoming and outgoing calls. Tap on the unknown number to see if any matches show up in your contacts, frequent callers, or recent outgoing calls. This can provide clues about who the caller might be.
2. Enable Announce Calls Feature
Go to Settings > Phone and turn on the “Announce Calls” feature. This will make your iPhone speak the caller’s name out loud when you receive a call if that person is saved in your contacts. For unknown numbers, it will say something like “Incoming call from unknown caller.”
3. Block Contacts Option
You can block specific phone numbers directly on your iPhone. Go to Settings > Phone > Blocked Contacts and add the suspicious phone number. This will send all future calls from that number directly to voicemail. You can always remove the blocked number later.
4. Look Up Unknown Numbers
Use Siri and say something like “Who just called me?” or “Lookup who this number belongs to” for an unknown recent caller. Siri will search your contacts, frequent callers and even do a basic online number lookup to identify anonymous callers.
Method 2: Use Third-Party Apps
The iPhone App Store has several excellent call identification and blocking apps to help expose unknown callers. Here are some top options to consider downloading:
1. Truecaller
Truecaller is one of the most popular apps for identifying anonymous phone numbers. Its community-based service has a huge database of known spam callers and telemarketers. When you receive a call, Truecaller can instantly match it against this database and verify if it is a scam risk.
The app also does real-time lookups against public data records to identify unknown numbers. You’ll see the caller’s name, location, company details, and more. Truecaller is free with ads or paid without ads.
2. TrapCall
TrapCall helps you unmask blocked callers using unique call-trap technology. When an unknown number calls you, TrapCall will ring once before disconnecting. This tricks the caller’s phone system into thinking the call was answered. When they call back, you will see their real number unmasked. TrapCall offers call recording and other premium features.
3. Hiya
Hiya combines spam call blocking with smart caller ID. It blocks known frauds and scammers automatically. When you receive a call, Hiya’s real-time lookup cross-checks the number against business listings, phone directories and other databases. This helps identify unknown caller details.
Hiya also shows risk profiles for spam numbers based on global user reports. The basic service is free, while premium options add advanced call blocking and reverse number lookup.
4. Whitepages
Whitepages is another longstanding reputation service. Their app lets you do reverse phone lookups quickly. Just enter the unknown number to see details like the owner’s name, address history, relatives, associates, social media profiles, and more.
Whitepages gets its data from public records, phone books and other crowd-sourced directory listings. The basic reverse lookup is free, while premium paid plans unlock more advanced background checks and call blocking.
Method 3: Use Your Carrier’s Tools
Most mobile carriers now offer built-in services to identify anonymous callers and block potential spam risks automatically. Here are some options if you want to leverage your carrier’s offerings:
1. Verizon – Call Filter
Verizon customers can download the free Call Filter app for Android or iOS. Use it to get spam alerts, automatically block robocalls, and even look up unknown numbers. Call Filter identifies high-risk callers verified by an aggregated global blacklist.
2. AT&T – Call Protect
AT&T offers the Call Protect app to warn you about fraud calls and block anonymous spam risks. Enable the app’s enhanced caller ID feature to automatically look up unknown caller information using real-time data analytics. You can see the caller’s name, location, and in some cases, why they are calling.
3. T-Mobile – Scam Shield
T-Mobile Scam Shield identifies scam callers and blocks them through personal call lists, crowd-sourced reported numbers and partner threat intelligence. The Scam ID feature does real-time lookups on unknown callers using proprietary algorithms and third-party databases.
4. Sprint – Premium Caller ID
Sprint customers can sign up for Premium Caller ID for $2.99 per month to identify anonymous numbers. When an unknown call comes in, you will see the caller’s name, location, and type of business if available. This extra context helps you decide whether or not to answer.
Don’t Forget Good Old Internet Searches
Modern search engines are incredibly powerful for digging up info on unknown callers. Here are some tips for sleuthing anonymous numbers with basic Google searching:
- General Search – Copy and paste the phone number in quotes into Google (ex. “123456789”). Go through top results to see if it is tied to any businesses or online profiles.
- Reverse Lookup – Try searching “reverse lookup 123456789” or “who called me from 123456789”. Several free sites like SpyDialer let you do quick lookups.
- Local Search – Add the number along with location keywords like “city, state” or zip codes. For example: “123-456-7890 Dallas TX”. This focuses results closer to the caller’s geo-area.
- Image Search – Search the number at images.google.com specifically. Profile pictures in results could identify the caller.
- Social Media Lookup – People often list phone numbers on social media profiles. Search Facebook, LinkedIn, Instagram and others by the unknown number.
- Forums – Search for the number on scam call reporting sites and forums to see if others have reported or discussed the caller.
Using search engines creatively can uncover helpful info on who an unknown caller might be. The wider the digital footprint associated with their number, the more signals you’ll have to triangulate the caller’s identity.
When All Else Fails, Let it Go to Voicemail
If you’ve gone through all these steps and still can’t identify an unknown number, the safest bet is usually to just let it ring and go to voicemail. But first, silence your ringer so you’re not disturbed by the call.
This approach triages scam risks automatically. Legit callers will leave a voicemail briefly explaining who they are and why they called. You can then call back once the coast is clear.
If it is a random spam call, they usually won’t bother leaving a message. Annoyed scammers may be tricked into revealing their real numbers if you enable TrapCall too. Letting unknown calls go to voicemail protects you while often providing the biggest clues to a caller’s intent.
How to Identify Who an Unknown Caller Is
Here are a few ways to identify who an unknown No Caller ID caller is on your iPhone:
- Check your call history – Even if the caller was labeled “No Caller ID”, the full phone number may be logged in your Recents call list. You can perform a reverse phone lookup on the number to potentially identify the caller.
- Use a call tracing service – Apps like TrapCall will cause a No Caller ID number to be unmasked when the person calls back after receiving a missed call alert. This reveals their real number.
- Contact your carrier – Your phone carrier may be able to determine the source number of anonymous No Caller ID calls if you provide them the date/time of the calls.
- Listen to voicemails – Callers leaving voicemails often inadvertently disclose identifying information about themselves that can hint at who they are.
- Block the number – Blocking the No Caller ID number will stop additional calls, providing a clue at their identity.
- Enable call announcements – Turn this on to hear the caller’s number read out loud if they leave a voicemail and it is detected.
- Let calls go to voicemail – Avoid answering anonymous calls. Wait for callers to leave a callback number in a voicemail instead.
- Report excessive unknown calls – If you believe you’re being illegally harassed, report it to the FCC/FTC and they may investigate.
With some smart tools and techniques, you can put a name to most anonymous No Caller ID callers that contact your iPhone.
How to Call Back No Caller ID
Here are some methods to call back a number that showed up as “No Caller ID”:
- Use Call Logs and History: Even if the caller’s number was hidden initially, it may still show up in your call logs or history later. Check your phone’s call logs right after getting a no caller ID call. On an iPhone, go to Phone > Recents. On Android, go to Phone > Call History. Scroll through to see if the number shows up. If you find it, you can call it back directly.
- Enable TrapCall: TrapCall is an app that can unmask blocked numbers when they call you. When you get a call from a hidden number, TrapCall will disconnect after one ring. This tricks the caller’s phone system into thinking the call was answered. When they call back again, TrapCall will reveal their real caller ID.
- Use *69 Call Return: Many phone carriers offer a *69 call return feature. After getting a call with no caller ID, hang up and dial *69 on your phone. This will call back the last incoming number, even if it was initially hidden. Note that *69 may incur additional charges, so check with your provider.
- Check Voicemail Metadata: If the anonymous caller leaves a voicemail, many voicemail systems record metadata like the originating number. Check your voicemail inbox for any messages from “Unknown Caller” or “Private Number” and look for a number in the details. Give that number a call back.
- Ask Your Carrier to Trace the Call: Phone companies can run a trace on nuisance calls to identify the originating number. Contact your carrier right after getting a problematic no caller ID call and request they trace the source. If successful, they may be able to provide actionable caller ID details.
- Block the Number: If you get repeated calls from the same hidden number, you can block it directly through your phone’s settings or with a call blocking app. This prevents future calls from ringing through while providing the number to block.
- Let it Go to Voicemail: To get the caller’s number safely, let no caller ID calls go to voicemail. Many persistent callers will leave a message with a callback number. Avoid answering anonymous calls to protect yourself from spam risks.
With the right tools and techniques, you can unveil and call back most anonymous and no caller ID numbers. Be proactive after each call to increase your chances of identifying hidden callers.
How to Find Out Who Called Without No Caller ID
Here are some methods to find out who called you from a number showing “No Caller ID” or “Anonymous”:
- Use a Reverse Phone Lookup Service: Reverse phone lookup services can help identify who a phone number belongs to. Sites like Whitepages and BeenVerified let you enter a phone number and search public records and phone directory listings to see the owner’s name and location. This can unmask no caller ID numbers.
- Check Your Recent Call Logs: After getting an anonymous call, check your phone’s call history/log immediately. Even if the number was hidden initially, it may show up in your recent calls list. On an iPhone go to Phone > Recents to find it.
- Ask Your Phone Carrier: Contact your phone carrier and ask them to look up the date, time and number that called you anonymously. Providers can cross-reference this with their internal records of callers to identify the source.
- Use TrapCall: TrapCall is an app that reveals blocked and anonymous caller IDs. It works by tricking the caller’s carrier when they call you, unmasking their real number to show on your phone. TrapCall offers a free trial to test it out.
- Block the Number: If the same anonymous number keeps calling, block it through your smartphone’s settings or a call-blocking app. Even though you can’t see the number initially, blocking it prevents future calls from that source.
- Listen to Voicemails: If the unidentified caller leaves a voicemail, listen closely for any identifying information they might reveal, like a name, company or return phone number. The voicemail metadata may also show a callback number.
- Report Harassing Calls: If you suspect illegal telemarketing or harassment from an anonymous source, report it. The FCC and FTC investigate caller ID spoofing and unwanted calls with enforcement options.
- Avoid Answering: Let unknown calls go to voicemail to protect yourself from unwanted spam and scam risks. Legitimate callers will usually leave a message or text their name. Avoid answering anonymous calls.
With some detective work and phone system tricks, you can uncover the identity of most anonymous callers. Being proactive will help you better understand who is trying to reach you and why.

No Caller ID vs. Unknown Caller on iPhone
There are some key differences between No Caller ID and Unknown Caller on an iPhone:
No Caller ID:
- This means the caller has actively blocked their number from appearing at all.
- No number will initially show on your iPhone – it will display “No Caller ID”.
- The caller has taken steps on their end to hide their caller ID information.
- This is often used by telemarketers or robocallers to hide their identity.
Unknown Caller:
- An unknown caller number is still transmitted, but iPhone doesn’t recognize it.
- Your iPhone will display “Unknown” instead of the number.
- The number is not blocked per se, it’s just not matched to your contacts.
- Unknown callers may include legitimate calls from businesses or individuals you know.
- The full number usually shows up in your call history allowing you to identify it.
Summary:
- No Caller ID means the number is intentionally blocked.
- Unknown Caller means the number is transmitted but isn’t matched to a contact.
- No Caller ID carries a higher risk of being unwanted spam or scam calls.
- You can identify both after the fact, but No Caller ID is harder to trace.
