An HTX list is a registry of account keys, and the CSV is its ledger. Each number has a role: KYC, 2FA, withdrawal, or recovery. The export has to show not just whether the number is valid, but whether it can still prove identity at the account’s next stage. Bulk HTX Number Checker is the ZelNum page that supports this job: HTX Number Checker.

Quick answer

Build the CSV with one number per row, a record ID, and a role column. Run the check and export with the status per row. Read the flagged rows as the review queue and the invalid rows as the replacement queue. The ledger is what makes a compliance review possible.

CSV setup

Column Why it is there
record_id Joins the result back to the source. Keep it as text.
input_number The original value, unchanged.
role KYC / 2FA / withdrawal / recovery.
status Valid / flagged / invalid / unknown.
checked_at The timestamp that makes re-checks comparable.

The role read

The role column is what turns a number list into a key registry:

  • KYC numbers anchor the identity record. They need to be valid and under the holder’s control.
  • 2FA numbers carry the verification codes. They need to be valid and current.
  • Withdrawal numbers confirm the request. They need to be under the holder’s control.
  • Recovery numbers are the backup path. They need to be reachable.

Reading the export

Say a compliance team checks 9,700 numbers. The export comes back 66% valid and active, 20% flagged, 10% invalid, 4% unknown. (These figures are illustrative, not a product performance claim.)

The flagged slice is the review queue, and most of it is KYC and withdrawal rows. The invalid slice is the replacement queue. Together they are the compliance work.

Routing the export

  • KYC and withdrawal, valid → keep, log the timestamp.
  • Flagged → review: does this number still belong to the holder?
  • Invalid → replace in account settings.
  • Unknown → retry.

Mistakes to avoid

  • Skipping the role column. Without it, the export cannot distinguish a KYC anchor from a recovery path.
  • Treating every valid number as a working key. Validity and ownership are different questions.
  • Treating the ledger as permanent. Re-check quarterly and before compliance reviews.

FAQ

Why is the role column important for HTX lists?

Because the same number has different jobs. A KYC anchor and a recovery path have different requirements, and the role column is what lets the export show them.

What is a flagged row?

A number where the signal suggests it may no longer belong to the account holder. In a compliance review, it goes to the review queue.

How often should I re-check?

Quarterly as a baseline, and before any compliance review.

Can this export support an audit?

Yes, and that is a main use. The role and status data with timestamps is exactly what an audit needs.

Should I merge duplicates?

No. Leave them in and let the checker report per row. Duplicates across roles are a signal worth seeing.
