Radaris Caller Id Phone Lookup

Review by eFreeware

An unrecognized number on the screen leaves you with two choices: answer and hope, or let it ring and wonder. For anyone dealing with a steady stream of telemarketers, robocalls and one-off nuisance dialers, neither option feels good, and the missed call that follows can nag at you for the rest of the day.

Radaris Caller ID Phone Lookup is built for exactly that situation. It comes from Virtura Corp. and sits in the Communication category on Google Play, where it has been available since April 22, 2022 and has passed 10,000 installs. The download is free, there are no ads, and in-app purchases are offered.

The pitch is straightforward: identify who is calling, warn you when a number looks like spam, and give you the tools to block it. The developer also ties the app to Radaris.com, a people-search site you can reach with a free account. The app currently holds a 3.5 average from 141 ratings, with 71 written reviews, which suggests a user base that is neither uniformly delighted nor dismissive.

What the app does about unwanted calls

The core job is screening. According to the developer, the app analyzes incoming calls and flags numbers that look like spam or fraud, so you can decide whether to pick up with some confidence rather than guessing. That screening runs against a database the developer describes as broad, and the app is pitched as a way to keep intrusive or potentially harmful calls from reaching you in the first place.

Blocking is the second half of that job. You can block unwanted calls directly, whether they come from persistent telemarketers, automated robocalls or someone who simply will not stop dialing. There is also a personalized blacklist, which lets you add specific numbers yourself and leave the rest to the app. That combination matters because automated detection will never catch everything a particular person considers unwanted.

What appeals to me here is the pairing of automatic screening with manual control. A pure blocklist puts all the work on you, while a pure spam filter gives you no say over the gray areas. Having both means the app handles the obvious cases and you handle the personal ones.

Caller identification and number lookup

Caller ID is the feature most people will notice first. When a call arrives from a number that is not saved in your contacts, the app is designed to show details about who is on the other end, removing some of the guesswork from answering. For anyone who takes calls from clients, delivery drivers or service providers, that context can be the difference between answering and letting a legitimate call go to voicemail.

The lookup side goes further. The developer describes the ability to look up information tied to any number, which is useful when you want to check a number after the fact, such as a missed call that left no message or a number that appeared in a text. Rather than sitting with the mystery, you can see what the app has on file.

The developer also connects the app to Radaris.com, where a free account opens up additional search options. That covers contact searches and public records searches, so the app works as a broader information platform rather than a single-purpose call tool. If you already use people-search sites for background checks or reconnecting with old contacts, that link is the part that extends the app's usefulness beyond the phone itself.

Setting up and what the app needs from you

One requirement stands out clearly. The app needs authorization to access your call log, because scanning incoming numbers for spam depends on it. The developer is explicit that this access exists to support the detection feature. That is a reasonable ask for a call-screening app, since the app cannot judge a number it never sees, but it is the kind of permission worth reading about before you install rather than after.

Signing up for free unlocks more search tools on Radaris.com. The app itself is free to download, carries no ads, and offers in-app purchases.

Support is handled by email at [email protected] for questions, problems and feedback. The app was last updated on July 29, 2025.

Where the numbers leave room for doubt

The app does its job for some users and frustrates others, which is common for tools that depend on a database being current and complete.

The permission requirement is the other thing to weigh. Granting access to your call log is not trivial. Anyone uncomfortable with that trade-off will find the app's central function hard to use, since the detection depends on it.

There is also the question of scope. This is a call-screening and lookup app first, with the people-search platform as an extension through a free account. Someone hoping for a directory that answers every question about every number may find the results narrower than the marketing suggests.

Who will get the most from it

The clearest fit is someone whose phone rings with more unknown numbers than known ones. If telemarketers, robocalls and unfamiliar area codes are a regular part of your week, the combination of automatic spam flagging, caller details and a blacklist you control covers the main ways people try to manage that problem.

Small business owners and freelancers who take calls from people outside their contacts are another natural audience. Seeing a name or some context before answering helps you decide whether to pick up, and the lookup tools let you check a number afterward when a call slips through.

The Radaris.com account adds a second layer for people who want to search beyond the phone. Contact searches and public records searches are a different kind of task from call screening, and the free account is what connects the two. If your interest is purely in stopping spam calls, the blocking and identification features are the part that matters; if you also want a broader search tool, the account is where that lives.

A practical pick for screening calls

Radaris Caller ID Phone Lookup covers the essentials of call management in one place: it flags suspicious numbers, shows details for callers you do not know, blocks calls you would rather not receive and lets you build a blacklist of your own. The link to Radaris.com through a free account extends that into contact and public records searches, which gives the app a second purpose beyond the phone.

The caveats are worth taking seriously. The app needs call log access to scan incoming numbers, which is a meaningful permission even with the developer's explanation.

I would point this one toward people who deal with a persistent volume of unwanted calls and want screening, identification and blocking together, especially if the people-search side appeals to them as well. If your calls are mostly from people you already know, the app's main features have less to do.
