Check the number before the number costs you the day
A flagged DID does not announce itself. Connect rates sag, agents blame the list, the list gets blamed for a fortnight, and the actual problem was a number that picked up a spam tag three weeks ago. Check it instead of guessing.
- Check known spam tags and reputation risk on a number
- Free, and no account required to ask
- Use it before a DID enters a pool, and when a pool starts sagging
- We tell you the limits of the check, not just the result
Why it matters
Reputation is inventory value
Numbers are not interchangeable. A DID with a clean history and a DID carrying a spam label cost the same to rent and perform nothing like each other.
Before it enters a pool
A number you are about to put in front of a market is worth thirty seconds of checking. Finding out afterwards means finding out through a fortnight of bad connect rates.
When a pool goes soft
When connect behaviour on one pool drops and nothing about the list changed, check the numbers before you rewrite the script and blame the agents.
Before you buy a block
Recycled numbering carries whatever the previous tenant did with it. Check a sample before you take the block, not after.
As part of rotation
Rotation, rest and warm-up are how you protect a pool. Checking is how you find out whether that protection is working.
What this does not do
The limits, stated up front
Every vendor in this space is happy to imply they can see every carrier label in every country in real time. Nobody can, so here is what we will and will not claim.
Coverage is not universal
What can be seen about a number depends on the country and on what is observable for that numbering range. Some markets are well covered; for others a check returns very little, and we say so rather than returning a confident-looking clean result.
A clean result is not a guarantee
No check proves a number will connect, and no check binds a carrier's future decision. Treat a result as evidence for your pool decisions, not as a warranty on the number.
Labels move
Reputation is a moving target. A number that checked clean last month can carry a label today, which is why checking belongs in your rotation routine rather than in your procurement checklist only.
We do not sell removal
We are not going to tell you we can strip a label off a burned number, and anyone who does is selling you something they cannot deliver. Rest it, rotate it, or retire it.
How to use it
Send the number, get the read
The check runs through our operator channel on Telegram — send the number in international format and we return what the check can see, including where coverage for that range is thin. No account, no billing, no obligation to buy anything afterwards.
If you would rather not send numbers to a stranger on the internet, that is a reasonable instinct, and it applies to every free checker on the market. Send one number from a pool you are already worried about and judge the answer before you send the rest.
Questions
Straight answers
- Is it really free?
- Yes, for reasonable volumes and without an account. We built it because number reputation decides whether our own customers' floors work, and a checker that only customers can use would be a worse tool for us as well as for you.
- Which countries are covered?
- Coverage varies by country and by numbering range, and it is not the same everywhere. We would rather tell you 'we cannot see much for this range' than return a confident result we cannot stand behind, so ask about the specific market you care about.
- Can you get a number unflagged?
- No. Anyone promising to clear a label is overselling. What actually works is not burning numbers in the first place: pools, rotation, rest, sane pacing, and a list you have the right to call.
- Do I have to be a customer?
- No. Use the checker, take the answer, and go about your day. If you decide you also want the lines, the numbers and the floor software behind it, that conversation is on Get Started.

Check one number and judge the answer
Send a number from a pool you are already worried about. If what comes back is useful, send the rest. If it is not, you have lost thirty seconds and owe us nothing.
