How it works
How a list gets cleaned
Four steps from a raw CSV to files you can use.
- Step 1
Upload a CSV
Drop in a CSV file. We read the header row and look for the column that holds the phone numbers.
- Step 2
Confirm the column
We pick the phone column and show a few values from it. Change it if we guessed wrong.
- Step 3
See the cost before you pay
You see how many unique rows there are and what they cost against your balance. Duplicates and empty rows are free, and nothing is taken until you confirm.
- Step 4
Download by verdict
Get the full file plus one file per verdict. Rows that come back unknown are returned to your balance, and we email you when it is done.
You see the cost before anything is taken from your balance.

The same checks as an API
One key. Send a number, read the verdict.
- Unknown results, bad input and errors cost 0 credits.
- Every error has the same shape: a code, a message and a request id.
- The docs are public. Read them before you sign up.

FAQ
Questions people ask
Short answers about verdicts, credits and lists.
What does each verdict mean?
Textable is a mobile number, which can be called and texted. Callable is a line that can take calls, such as a landline, a toll-free number or a VoIP number. Invalid is not a working number. Unknown means we could not tell, and you are not charged. A verdict says whether a number can be reached. It says nothing about whether you may contact it.
Does textable mean I am allowed to text the number?
No. Textable means the number is a mobile line that can receive a text. Whether you may text it depends on consent and on the Do Not Call rules that apply to you. We do not check either, so keep doing that yourself. If you are unsure, ask a lawyer.
Do credits expire?
No. Credits from a pack never expire, credits from a plan never expire, and neither do the free credits you get at sign-up. If you cancel a plan, the credits already on your account stay there.
What am I charged when a result is unknown?
Nothing. A result of unknown costs 0 credits. So does input that is not a phone number at all, an empty row and any error. In a bulk list, duplicate rows are free, and rows that come back unknown are returned to your balance when the list finishes.
Can you tell me who owns a number?
No. We return the line type, the carrier and the region, and nothing about the person or business behind the number. A carrier is the company that holds the number, not the person who uses it. We do not offer name lookups or reverse lookups.
What happens to my uploaded lists?
The file and the result files are kept while the job runs and for a fixed number of days after it finishes, then deleted automatically. The number of days is on this site and on your results page. The numbers in your list sit in those files and nowhere else we keep: the lookup cache stores a keyed hash of each number with what the carrier said, not the number. We email you when the job is done.
