About CallerCheck: Independent Guides to Spam-Call Defense
Short answer
CallerCheck publishes independent guides that help you decide whether an unknown call is spam or a scam, whether to answer, and how to block and report it with tools you already have. We are not a lookup database, we do not sell one, and we are not affiliated with any carrier, phone maker, app, the FTC or the FCC.
How we handle what you shareNo sign-up and no lookup form; nothing to type in to read a guide.
- Defense only
- Every guide is about calls you received: screen, block and report them.
- Independent
- No carrier, phone maker, app or government agency pays for or approves our guides.
- Sourced and dated
- Guides point to official FTC, FCC, Apple, Google and carrier pages; comparison tables show a review month.
What we ask of you, and what we don't
Reading a guide here never requires handing over a phone number or personal details.
- No number-lookup service
- We don't run a reverse-lookup database, so there is no box on this site that asks you to type in a number.
- We don't ask for the number that called you
- The guides work with your own phone, carrier and official report forms; the number stays with you and those channels.
- No account, no sign-up
- Every guide is readable without registering, so there is no profile or contact list for us to keep.
- No paid lookup upsell
- We don't sell reports about callers and we don't send you to services that promise to reveal who owns a number.
How our guides are made
Each guide is written against the same checklist of sources and caveats.
-
Official sources first
Facts come from the FTC, FCC, Apple, Google and carriers' own help pages.
-
Review month shown
Comparison tables carry a last-reviewed month so you can judge how current they are.
-
Hedged when unsure
If a menu or carrier feature varies by version or region, we say so plainly.
-
No endorsements
Apps and carrier services are described generically, with no ranking bought by anyone.
Note: Menu names and carrier plans change; the official page linked in each guide is the final word.
What we promise, and where each promise stops
These are commitments we can actually keep, each with its limit stated up front.
-
Every guide ends with a real action you can take today: a setting, a block, or an official report form.
The limit: We will not help find, track, locate or unmask a private person from their number.
-
Where a step depends on an outside service, we link its official page rather than retelling it from memory.
The limit: We can't control those pages, so a menu or form may change before our next review.
-
When we learn a step is outdated, we correct the guide and, where a table is affected, update its review month.
The limit: We review guides periodically, not in real time, so a very recent change may not be reflected yet.
-
We tell you honestly what the tools can and can't do, including that blocking reduces spam rather than ending it.
The limit: No guide can stop every spam call or recover money already lost; for that, report to the FTC and your bank.
Note: We do not identify callers, we are not a people-search or tracking service, and we do not speak for the FTC, the FCC or any carrier.
Questions people ask
Is CallerCheck a reverse phone lookup service?
No. We run no lookup database and sell no reports, so there is nothing to type a number into and nothing to pay for. The guides cover what you can do yourself: screen, block and report calls through your phone, your carrier and the FTC or FCC.
Are you connected to the FTC, the FCC or a phone carrier?
No. CallerCheck is independent and is not affiliated with any carrier, phone maker, app, the FTC or the FCC. We link to their official pages so you can act through the real channels, such as the National Do Not Call Registry or the FTC's fraud report form.
How do you keep guides accurate?
We build each guide from official sources: consumer.ftc.gov, fcc.gov, donotcall.gov, Apple and Google support pages, and carriers' own spam-blocking pages. Tables show the month they were last reviewed, and where details vary by phone, OS version or carrier, we say so instead of guessing.
Why don't you name or rank caller-ID and spam-blocking apps?
We describe apps and carrier services generically so no company can pay for placement or a better rating. Features and prices change, so check the app store listing or your carrier's official spam-blocking page before you install or subscribe to anything.
Do you check where a number is registered or which operator it uses?
That is not what this site covers. CallerCheck stays on screening, blocking and reporting unwanted calls; operator and region details are handled by a separate sister project, NumInfo.
