NumberGuru, revamped and better than ever, is your one stop CALLER ID, reverse phone number lookup and spam BLOCKING app!

Are you getting phone calls or text messages from UNKNOWN numbers? Getting bothered by pesky debt collectors, annoying telemarketers or vicious scam artists? With NumberGuru, one may instantly perform a reverse phone lookup to find important details about the caller BUT now also BLOCK the number directly from our app with a click of a button.

NumberGuru's phone number reports may include the possible owner lookup, location of the phone caller, the number's carrier, spam scores, the type of caller plus much more!

Wait… there’s even more! NumberGuru’s premium public record reports also include People lookups, Email address lookups and Property searches.


Wondering who keeps texting your significant other every night? Want to know who sent that annoying message at 6 in the morning?

Search a number in our reverse phone number lookup directory and let the NumberGuru do the work! You may instantly find where the phone number is located, who the unknown number might be, whether it is a landline or cell phone number and if it is a spammer.


And with our people lookup, you can potentially see names, known aliases, contact information, address history, educational info and even criminal reports.


When you sign up for a social media account, part of the fun is coming up with a clever username. You can choose a variation of your name or words that reflect your interests or personality, but whatever you choose has to be unique. For that reason, a username search tool can be invaluable when you're trying to look up someone.


Want to learn more about a home for sale without calling a realtor? Or maybe you’re curious about the neighbor who moved in across the street. Reverse address lookup gives you a view into a piece of property and the people who live there.


Your online identity may be at risk, see what information may be out there about you by performing a Dark Web Scan.


Free yourself from annoying telemarketers & phone scammers. With the NumberGuru spam identification (Spam ID) feature we will let you know when we’ve identified a spam call right within your native phone app!

Plus, you can leave comments to alert others on whether someone is a telemarketer, scammer or prankster as well as view other top searches on a daily and hourly basis.


Search a number to find important details and then with a few simple clicks Block a number instantly.

Use to be my go to

This use to be my go to so that I can confirm numbers. But now names are no longer given when doing a search. You now have to pay I guess. Sad, I understand they have to make money some way outside of collecting data and usage but without having the names the app is no longer needed.

Hi there,

I'm sorry to hear you had any trouble getting the information you need.

NumberGuru is an easy-to-access collection of public record information. Public records are collected through official government records such as mortgage deeds and court records, and through sources such as magazine subscriptions, warranty cards, and utility bills.

The results of a Reverse Phone Search can contain caller id data, phone records data, deep web search and more. Typically, we are able to provide the name of the owner and his or her address, in the full phone report.

If we are not showing some elements of this information in the results of your phone search, then we do not currently have that information for the number in our database. Please know that we are constantly updating and expanding our database to provide the most accurate and current information we possibly can.

When you search a number, we do not provide texts sent or received by that number or call logs for the number. We do not provide the physical location of the phone itself, such as with GPS tracking, etc. The information in our reports comes from public records and this information is not publicly available data.

If you have additional questions, please don't hesitate to contact us.

Used to be a good app, but now it’s horrible

I used to love this app. It worked great and would give me info on callers. Now it gives me nothing. At one point, I paid $40 for the upgraded version to get better results, but the app was later updated and now it wants me to sign up for premium service…? Why did I pay $40 already?

I keep it in my phone hoping somebody it will return to its previous functionality, but every time I try to check a number, it fails me.

This all is a waste of time and money. Great app idea, but apparently greed of the developer has ruined it. Fix it and I’ll redo my review.

This app prevented me from calling 911. I am not joking of confused. My husband had a medical emergency and I repeatedly attempted to call for help, but my call would not go through. I had to call my father-in-law, and in a panic, scream for him to have an ambulance sent to our home. It was the most terrifying event of my life. Once we were at the hospital, I had a moment to look at my phone to try and troubleshoot what had happened— each call I had attempted to make to 911 was flagged by Number Guru, and was canceled. I had more than a half dozen unsuccessful calls!!!
