Can I check a whole list?

Yes, in a free workspace. Upload a CSV or XLSX up to 5 MB and 200,000 rows. The API takes up to 10,000 numbers per request.

What happens to what I enter?

Results aren’t saved to an account, and query data is deleted within 24 hours.

What do valid, invalid and unknown mean?

valid means the number is in use. invalid means the number is out of use. unknown means the signals did not agree.

What is the difference between a valid format and an active number?

A valid format means the number sits in a real numbering range. An active number is in use today. The checker returns both.

Is this an HLR lookup?

The check is eHLR, ScoreMachine’s own activity check. eHLR combines telecom network signals with digital footprint data. eHLR also returns a verdict where a home location register (HLR) lookup comes back empty.
