Three Tips for Conducting a Reverse Phone Number Lookup

Posted by Writing PIs on September 5, 2015

There’s lots of ads out there for free phone look-ups — often what you get is some free information (such as the possible geographical location of the phone carrier), then they ask you to “click here” and for $1.95 or $34.95 (prices vary), you can get the full report on this person.

Buyer beware.

There’s no magical 100% correct database out there that’ll spit out the latest and greatest information associated with a phone number. We’re not saying you can’t get correct information. You might. But you, the buyer, should know that you are paying for information that could be outdated, input incorrectly into a database, or the phone number might have been correct at one time but has since been ported to a new carrier.

Saying all that, here are three tips to conduct a reverse check on a phone number:

Tip #1: Run the phone number in Google. Google remains the most comprehensive, free public search engine. Search results reflect every document, website, blog, resume, ad (such as Craigslist), and other online places where that phone number displays.

We once found a person who was on the run by conducting a reverse cell phone number search in Google. Although she had disconnected her cell phone service, that number was still listed on her MySpace site, which she had kept public (not private), meaning anyone could read her comments. Although she had worked to cover her tracks, she was taking the time every day to log into her MySpace account and chat with friends. And we were taking the time every day to read where she’d eaten lunch, what time of day she drove into a certain town, what motel she was staying at, and more.

Tip #2: Check the carrier, geographical region for the number. There are sites that offer free checks for type of phone line, carrier, and geographical region of the phone number. One site is Phone Validator, another is SpyDialer, the latter also offering options to hear the person’s voicemail message and look up the phone owner’s name and photo.

Again, keep in mind that the information returned is only as good as the database, and there’s no guarantee how recently the information has been updated. For example, I just ran my personal cell phone number in SpyDialer, and although it got my first name correct, it displayed a photo of what appeared to be a restaurant along with a man’s name. Perhaps he (or the business) had this number before me.

Tip #3: Hire a private investigator.  A qualified PI is experienced at digging for information and can interpret its accuracy or legality. To find a PI in your area, contact the professional investigators’ association for your state: Private Investigator Associations by State (

Last winter, Shaun (now a criminal lawyer), cross-examined an investigator during a trial. Key to the case was the owner of a cell phone found at an apartment. The investigator said it belonged to the guy whose bedroom he found it in. Problem was, there were multiple bedrooms and roommates at this residence, with recent parties in the apartment attended by others, so deciding ownership solely on where the phone was left was flimsy evidence. Shaun then asked the investigator if he’d run a reverse on the phone. That story is here:

Answering Writer’s Question: Finding Someone’s New, Bogus Online ID

Posted by Writing PIs on July 30, 2015

A writer asked, “I’m trying to figure out how a PI would discover the identity of someone who has intentionally (but not through legal channels) ditched a previous identity and assumed a new one. This person claims to be an immigrant from IT but is American.”

It appears this writer would like a PI character to detect the new identity based on the old one. We have a few ideas. But first, a few caveats:

We’re limiting this search to a possible new online ID.  After all, assuming a new ID in a broader context — new home address, new driver’s license, and so on — is a large topic, one entire books have been written about. We’re not recommending any of the following books, just noting they exist: How to Disappear: Erase Your Digital Footprint, Leave False Trials, and Vanish Without a Trace by Frank Ahern; How to Be Invisible: Protect Your Home, Your Children, Your Assets, and Your Life by J.J. Luna.

As to the individual claiming he’s an immigrant from IT: We’ll assume for this post that IT = Italy. While a PI is conducting his/her search on the new ID, they would keep an eye out for any Italian references, names and so forth in the results. Of course, based on the writer’s scenario, the guy isn’t really from Italy, but if he’s pretending he is, such a reference might pop up.

We’re providing these ideas for the sake of a story. However, in real life we’d recommend a person retain the services of a professional PI who specializes in locating people (AKA skip tracers). To find a skip tracer, contact your local state professional private investigator association: Private Investigator Associations by State (PINow). For example, a PI can run a person’s SSN in a proprietary database and learn a lot about the individual no matter what online IDs this person is juggling.

Now let’s look at three free online ways a fictional PI (or even a non-PI) might try to discover the identity of someone’s new online ID based on their old (ditched) one. For our example, we’ll call the old ID “Joe Smithy.”

1. What phone number did Joe Smithy use?

We once had a case where a man had been operating as multiple IDs on different dating sites, often ditching one ID and creating another to fit his needs. Except he kept the same phone numbers! Which we discovered when we ran a single reverse on a number he had provided our client (before he “disappeared” online) — and we discovered he was still using that old number.

Yes, from a single reverse phone number search on Google, we got a listing of his interactions & IDs on different dating sites. Our poor client was devastated — she had never heard of a reverse phone number search before…but after learning how easy it is to run one, she saw for herself how busy this guy had been elsewhere. For more info on reverse number searches: How to Reverse Search Phone Numbers.

2. Did Joe Smithy have a photo?You can run a reverse photo search on Google

Google has a comprehensive reverse photo search option where anyone can plug in the photo and run a search on it…it’s possible Joe Smithy’s photo is appearing under his new ID. To learn more about running a reverse image search on Google: Fast and Easy Google Search Tips (scroll to Trick #2: Use images to search for photographs, illustrations and other graphics). Another free reverse photo search engine is TinEye.

3. Know Smithy’s hobbies, nicknames, etc.?

Run them in a social media search engine and see what pops up. For example if Joe Smithy was an avid online poker player, run “Joe Smithy poker” and see if a new ID is popping up on sites where Joe’s used to. We wrote about these search engines here: Free Social Media Search Engines.

How to Reverse Search Phone Numbers

Posted by Writing PIs on June 27, 2010

Sometimes it’s handy to reverse search a phone number, which means to find information associated with that number, such as a name or address. You can reverse search a number through reverse telephone directories (also called cross-cross directories) as well as online through various search engines and online databases.  Let’s look at a few free searches: reverse directories and some cool databases.

Look-up the Number in a Reverse/Criss-Cross Directory: You can find these at your local library. Instead of listing numbers by surnames, these books list information by categories, such as the number’s prefixes, street addresses, sometimes professions, and more.  If you’re unsure where reverse directories are maintained at the library, ask a reference librarian for help.

Run a reverse phone number in Google. Google’s our first, quick search for just about anything because it’s the most comprehensive, public search engine currently available.  Just type the number into the browser, press the “Google Search” button, and view the results.  Everywhere Google finds that number will display (for example, in websites, online resumes, social networking sites, and so on).

Check phone number via SPYdialer: SPYdialer is a free phone number lookup that searches both landlines and cell phones, providing the registered user’s first or last name and general region in its results. You can also request a photo lookup based on the phone number & SPYdialer will search for that person’s photo on social media — if a facial photo isn’t found, SPYdialer posts a generic photo of the region from which the phone number originates (be sure to read the fine print as SPY dialer explains why a photo was selected if it couldn’t assign a facial image to the number).

Have a great week, Writing PIs
