Find a Cell or Landline Phone Number Online

A cell or landline phone number lookup has never been easy, but these tips help.

Public cell phone directories are hard to find, but that doesn't mean they're impossible to get a hold of. There are several tools you can use to track down who owns a phone number or dig up someone's personal or business phone numbers.

Cell phone lookup sites are available in two forms: find a cell phone number by searching for some other information you know about the caller, or look up someone's number to see who owns it (called a reverse number search). You might need your own mobile number directory if you lost a friend's number, you're trying to contact distant relatives, or you're curious who just called you.

Below is a comprehensive look at the best ways to use the internet to find phone number information.

How to Find Out Who Called You

If you are frequently on the receiving end of unwanted calls, and you know who the caller is, you can use your smartphone’s options to block that specific number. However, the problems start when someone is calling you from a masked, unknown number.

Reverse phone lookup is both free and paid. Normally, it is free for landline phone numbers, but if you want to search for the owner of a mobile number, you have to pay. I'd say you 'had' to pay because so many apps have cropped up that offer this service for free. An interesting number of websites and apps for Android and iOS exist that have rather huge databases of mobile and landline numbers, and offer reverse phone lookup for free, without any limitation.

You should not consider the cost of reverse phone lookup to be solely in terms of money. You need to be aware that you pay with your privacy as well. By installing and using a reverse phone lookup app on your smartphone, you are giving the service behind all rights to use your number and whatever information they can gather about you along with it to feed their database so that other people can find you when they search for your number.

The app also does some mining in your contact list and gathers a lot of information about your contacts to feed their database. For us the equation is clear; if you want to get the most of free reverse phone number lookup apps, you must be ready to forget about the privacy of your phone number and that of the numbers in your contact list.

As mentioned above, some free services request you to sign in your Facebook or Google account before being able to use the service for free. Most people are already signed up with their browsers on these services so they are not prompted. Now guess why they want to service you inside your personal social network account? So they can extract a maximum of information from your account full of links to other people, and full of biodata about these people. This is how they build their database.

When testing a reverse number lookup app, one of the mobile numbers tested brought back the wrongly-written name and a picture that which was obviously taken without knowledge. We inferred that the app crawled and dug that name and picture from the contact list of one of the acquaintances who saved that number on their smartphone with the mobile number's owner's name wrongly written and a picture they took.

Now, the dreadful thing is that even if you try to stay away from these privacy-busters, chances are that your data are already in their database. What can you do about it? Not much, save that you can request that they remove your phone number, and subsequently all the data that goes with it from the list. We know TrueCaller offers this. But each app is different.

Even if you register your phone number in the National Do Not Call Registry, chances are good that you will still get some unwanted calls and texts. Robocallers are relentless; they can not only disrupt your day but, if they gain your trust, scam you out of money. Likewise, malicious text messages may attempt to solicit information that's best kept private. Even if callers and hackers don't succeed, such texts and phone calls are annoying and a hassle to deal with. Here are a few ways you can stop them.

A few call-blocking apps are available for Android. One example is PrivacyStar (also available for iOS). It gives you control over calls and texts from not just individual numbers but numbers that are unknown or private.

PrivacyStar's crowdsourced database of blocked numbers can expand your blocked list to include the worst offenders, and you can file complaints with the government for calls and text messages that are spam.

If you still have a landline phone number, you may have even more robust blocking capabilities. For example, you may be able to enter specific phone numbers you want to block permanently on your service provider's website.

Verizon, for example, has an option to block anonymous callers, but it's not very reliable; "unavailable" phone calls can still come through. If worse comes to worst and spammy robocallers are driving you crazy, contact your phone company with the numbers on hand to have them blocked permanently.

Annoyances aside, unwanted and anonymous calls can be as much of a security risk as they are aggravating. Avoid the worst that could happen by dealing with these threats wisely:

Don't respond to unwanted calls, even if the call prompts you to press a number to opt out of future messages. All that will do is verify to the spammer or scammer that your number is valid.

Similarly, don't respond to unwanted text messages or click on any links. (This holds true for text messages, emails, voicemails, and phone calls.)

Register your phone numbers with the National Do Not Call Registry.

Don't enter your phone number in online or offline forms unless it's really necessary. Burner is a great privacy app for iPhone and Android that provides disposable phone numbers so you can protect your privacy.

Telemarketers have been around since the dawn of the telephone, but as yet, there's no way to prevent their intrusions completely, so it remains up to phone users to be proactive.

Google used to have a phonebook service, but it was taken down when people started wanting their information removed from the service. Therefore, Google isn’t the best choice for someone to look up another person’s number.

Even on the off-chance that Google has any information in regards to who has been calling you, it may not be reliable or up to date. I know it’s simple to lookup a phone number on Google. It’s certainly worth a try. However, don’t get your hopes up as it is more than likely that you won’t find any current owner information on the phone number n question.

The area code listed on the phone number that keeps calling you may give you more insight into what kind of call it is than you realize. Foreign area codes are most of the time scammers.

Toll-Free numbers like 800 or 844 are usually telemarketers. Always beware of toll-free numbers and calls coming from outside of the US. Also look at this list from Forbes to see the some international area codes that are unsafe.

Additionally, the area code will give insight into where someone lives. In the illustration below, you can see that 5.7 million cell phone numbers start with 917. If you look up that area code from a cell phone number, you will discover that the caller lives in New York City.

Google a phone number – it’s amazing what you find out!

Type a phone number, for example: 0843 410 4689

Go ahead – Google a phone number that called you, see if it’s mentioned in a forum or discussion. You’re often not the only one receiving the calls and it tells you in the results who’s number it is.

End the frustration and worry of trying to figure out who called you. Was it a relative or friend you hadn’t heard from for ages, or was it a hoax caller or a scam? In the example above, the caller was a PPI company.

People receive lots of calls from people claiming to be from Microsoft, asking you to turn your computer on so that they can take control. They will try and trick you into revealing passwords and personal information. Do not be worried as there is nothing wrong with your computer – hang up, and notify the police if the caller is persistent.

It’s not uncommon to receive a telephone call from an unfamiliar or unknown number. While it may be easier just to pick up the phone, that might not be a good idea.

Unfortunately, with today’s technological advantages, it is never safe to answer a call if you’re not sure who the caller is.

Thanks to technology, spammers can easily trick you into answering your phone. They use tactics such as neighbourhood spoofing, where they change the number that displays on the caller ID so you think that you’re getting a phone call from a local number. There are many more tactics that can be used to manipulate phone calls.

It’s never safe to answer the phone if you’re not sure who’s on the other end. Below I have included five advanced methods to help you determine who is calling you on the other line. Using these methods, you can determine if the person calling is safe or not without even picking up the phone.

Google has always been a great resource to find anything that you’re looking for, from relationship advice to how to fix your computer. Sometimes, if you type a number in Google, results will pull up that will show the owner of the cell phone number.

Of course, you will have to visit the web pages of these results to see who the owner of the number is, and sometimes you have to pay a fee. Additionally, be aware that these results aren’t always accurate, and you may find no results at all when you perform a Google search on a phone number.

Cell phone lookup sites are available in two forms: find a cell phone number by searching for some other information you know about the caller, or look up someone's number to see who owns it (called a reverse number search). You might need your own mobile number directory if you lost a friend's number, you're trying to contact distant relatives, or you're curious who just called you.

Below is a comprehensive look at the best ways to use the internet to find phone number information.

There are hundreds of millions of people active on various social media sites all over the world. Many people use these websites to share information with each other, and yes, that does include phone numbers. Simply type the person's name into the site's search function and see what comes back.

Some people might have their social media profile set to private or might require you to connect with them on the service before you can view personal details like their phone number. However, others are wide open, and their phone number and other details might be entirely public.

Depending on the social media site you use, you might be able to search for a number using the person's name and find who owns a phone number if you don't know their name, all at no charge.

Some apps even extract information out of the contact lists of their users and feed their databases from them. They also explore the communication networks and links of their users and intelligently extract meaningful information to substantiate data around phone numbers. So, if you are looking for a reliable reverse phone lookup app or service, look for one with the biggest database of numbers.

So, it is not necessary that each and every phone number out there has a record for it in one of the reverse phone lookup databases, and those that do have a record do not necessarily have meaningful data about their owners. Actually, most phone numbers (especially mobile) are not present in those databases. This is why you will not always get satisfactory results. But this is about to change, with the intrusive nature of the crawlers working behind the reverse lookup apps, and with the rate at which third-country markets are upgrading.

The results you will surely get, but not always what you want. For example, it is easy for the apps to deduce which country a number is from, and which operator runs it. For example, you can see a result of something like "Manhattan, Sprint". No name. While to some it may be useful, it is not what people want from reverse phone lookup.

Another problem you can come across with reverse phone lookup is obsolete information. The lookup service may have gathered the information of a previous owner of a number in the directory. When you search, you miss the new owner and get the old one.

On the other hand, we have to note that some apps give a huge number of hits. So much so that many of them offer paid service for reverse phone lookup, and refund in case the results are not to expectations. For instance, TrueCaller boasts of having more than two billion numbers in its database and, more interestingly, it is free. However, you may be asked to throw in something instead of the money. For instance, you may be asked to sign in using your Facebook or Google account to enjoy the free service.
