Evidence
Inventory the archive
Look for form locale, campaign market, country field, and export notes. Record which source supports each normalization rule.

HTX Number Checker for Legacy Phone Data
Older Huobi-labelled exports often contain national-format phone numbers and little documentation about the collection country. Prepare a defensible international value, then check the usable rows for current HTX registration signals.
Use it for archived phone rosters where source lineage and country reconstruction matter as much as the lookup itself.

Workflow illustration. It is not a live task, performance claim, or promised response schema.
Archived phone data needs provenance
Recover country context before building the HTX batch
A phone value may have been valid when collected but become ambiguous after the country column or form configuration was lost. Treat reconstruction as a documented data-recovery task.
Transform
Write to a new column
Create htx_phone_e164 and normalization_rule_id. Never overwrite the archived phone value, even when the conversion seems obvious.
Exclude
Hold unresolved records
If two countries produce plausible numbers, mark country_ambiguous and leave the row out of the paid HTX task.
Archive-recovery example
Make the normalization evidence part of the result
This file shape lets a reviewer distinguish a lookup outcome from a choice made while reconstructing old phone data.
| archive_id | raw_phone | normalization_rule | HTX outcome | review_reason |
|---|---|---|---|---|
| HX-2019-88 | +1 202 555 0162 | already-E.164 | Matched | None |
| HX-2019-94 | 07700 900612 | source_region=GB | Unmatched | None |
| HX-2019-97 | 020 555 0194 | no reliable country | Not checked | country_ambiguous |
Fictional examples illustrate data lineage. The checker does not recover missing country context; that is a preparation decision made by the data owner.
Legacy phone review
Report confidence in the input separately from the HTX result
A matched result on a poorly reconstructed number is not a high-quality answer. Score the preparation evidence and the returned registration signal as separate fields.
Input confidence
Grade the country evidence
A supplied plus-prefixed number is different from a national number inferred from a campaign market. Preserve that difference.
Lookup outcome
Store the HTX status as returned
Do not rewrite a review response as unmatched for reporting convenience. Keep the checked value and task reference.
Archive exception
Document why a row was excluded
Use reasons such as missing_country or malformed_phone so the recovery backlog can be measured and revisited.
Decision owner
Assign the final interpretation
Data teams can prepare and report the signals; the campaign or compliance owner should decide what action the historical program allows.
Archive cleanup cost
Exclude unresolved phone rows from the paid batch
The reference price displayed is $7 per 10,000 checks. Calculate the run after country reconstruction and format review. Confirm the current rate in the app before submitting the archive.

HTX legacy phone-list FAQ
Can I check phone numbers from an old Huobi export for HTX signals?
Yes, if you can prepare reliable international phone values. Preserve the Huobi-labelled source fields and store the current HTX result separately.
What if the archive contains local numbers but no country column?
Look for reliable source metadata. If the country remains ambiguous, hold the row out of the lookup rather than applying an undocumented default.
Does BulkChecker reconstruct the missing country automatically?
This page does not claim that. Country reconstruction is a data-preparation step that should use evidence from the source system or campaign owner.
Can a current match prove the number was registered during the old campaign?
No. Treat the result as a current account signal unless the returned product data explicitly states otherwise.
Why keep a normalization rule ID?
It lets reviewers see how a national number became an international one and helps you correct every affected row if the rule was wrong.

BulkChecker is not owned, operated, or endorsed by HTX. Use only data you are authorized to process, minimize uploaded fields, and treat registration results as supporting signals rather than identity, ownership, KYC, fraud, or consent decisions.
