Which LINE checks are currently supported?

Should I check registration or activity first?

How should I prepare the input file?
Use a TXT file with one phone number per line. Keep the original value, normalize country codes and formatting, remove obvious duplicates, and validate a small batch before a larger run.
How should I read the LINE reference rates?
Current volume reference rates are Registration check: 9 credits / 10K numbers; Gender & age: 35 credits / 10K numbers. Credits are purchased with USDT; available fields, task status and final credit deduction are confirmed in the signed-in dashboard or with official support.
Can check results be used as marketing consent?
