Manual CLI check
We dial your number to a real handset on the destination network and photograph what it displayed — the number shown, the name shown, and anything else riding along with it.
Available in USA, India and Nigeria.

Four ways to test your caller ID
Each one answers a different question, and each one ends in evidence from the receiving side rather than a status from your own system.
Truecaller reputation check
We read your number the way Truecaller shows it to its users — the name on the listing, and any spam flag attached to it.
Available in USA, Canada, India, Nigeria and many more.
Hiya reputation check
The same reading against Hiya, which is what matters for traffic into the UK and Europe.
Available in the UK and Europe.
Echo-back audio test
We place a real call and play the audio back to you, so you can hear what survived the route instead of taking the carrier at its word.
Available in every country.
How the check works
Three steps, one screenshot
1. Choose a check. A reputation lookup tells you what Truecaller or Hiya says about your number. An echo-back call lets you hear your own audio after it has crossed the route. A manual CLI check dials a real handset in the destination country and photographs the screen.
2. Enter the number your customers see. Not the trunk, not the account number: the presented caller ID. If you rotate a pool, test each line.
3. Read the result. You get the name shown, the number shown and any label riding along with it, with a timestamped screenshot. That screenshot is what makes the conversation with your carrier short.
Caller ID, CNAM and spam labels
Why a verified number can still ring as "Spam Likely"
Three separate systems decide what a phone shows when you call. The caller ID is the number your carrier presents. CNAM is the name a US or Canadian terminating carrier looks up against its own database, which may be months out of date or empty. The spam label comes from analytics engines run by the carriers and by apps such as Truecaller and Hiya, which score your number on volume, call length, answer rate and user reports.
Your dialler sees none of this. A call that connected, a call that rang blank and a call that rang with a red warning are all logged the same way. That is why answer rates fall for weeks before anybody notices, and why the first useful step is to test the caller ID from the receiving side.
A caller ID test is also the fastest way to catch rewriting on international routes. Traffic into India, Nigeria and much of Europe passes through carriers that may strip or replace the presented number, so the customer sees a different number from the one you sent, or no number at all.

Questions
Caller ID check questions
How do I check what my caller ID shows?
Pick a check above and enter your number. We read it the way a real handset or a reputation app does and send you back the name, the number and any label that displayed, with a screenshot. The first checks are free and you do not need an account.
What is the difference between caller ID, CNAM and a spam label?
Caller ID is the number the handset receives. CNAM is the name a US or Canadian carrier attaches to that number from its own database. A spam label such as "Spam Likely" or "Scam Likely" comes from a third source again: the carrier's analytics engine or an app like Truecaller or Hiya. All three can disagree, which is why a number can look fine on one phone and get rejected on another.
Why does my business number show as Spam Likely?
Carriers and reputation apps score numbers on call volume, answer rate, call length and user reports. A new number that dials hundreds of short calls a day looks exactly like a robocaller to that model, even when every call is legitimate. The label is applied without telling you, and your dialler still logs the call as connected.
Can I test my caller ID online for free?
Yes. The Truecaller, Hiya and echo-back checks on this page are free for your first attempts and run without an account. Manual checks on a real handset in the USA, India or Nigeria, and bulk checks across a whole number pool, need a free account with starter credits.
How often should I test my numbers?
Before a number goes into rotation, and then on a schedule. Labels change without notice, so teams that dial every day usually check their pool daily or weekly and pull a flagged number the same day rather than after a bad month.
Do you test on real phones or from a database?
Manual CLI checks are placed to real devices on real networks and photographed. Reputation checks read the live Truecaller or Hiya listing. Echo-back places a real call and plays your audio back. None of the results are simulated.
How do I remove a spam label from my number?
Once you have evidence of the label, register the number with the carrier analytics providers and the app that shows it, keep call patterns consistent, and retest. The screenshot from a check is what makes the remediation request credible, so run the check first.
