South Korea WhatsApp Number Checker: +82 Registration Guide: task scope, TXT input, Excel output fields, and validation boundaries.

A South Korea WhatsApp number check verifies registration signals for +82 numbers; it is not evidence of market share or channel preference.

What this task actually answers

A South Korea WhatsApp number check verifies registration signals for +82 numbers; it is not evidence of market share or channel preference. Define the business question first and select the smallest service that answers it.

Prepare phone numbers before upload

Start with a list that has a documented source and permitted purpose. Verify country codes, deduplicate, remove spaces, brackets, hyphens, names, and notes, then save one phone number per line in TXT. Excel and CSV are not accepted upload formats.

Use the TXT-to-Excel workflow

Submit a small sample to the selected WhatsApp (WA/WS) task. Record the service, input row count, operator, and check date. Export Excel when processing finishes, preserve the raw result, and match it back to the CRM by original number or internal ID.

Interpret output fields correctly

Registration Check returns the phone number and registration status. Activity Check adds activity time, active days, and a mapped number. Profile Picture Check may return business-account, picture, and mapped-number fields. Full Format combines a wider set of supported fields.

The check most teams miss

Do not mechanically keep or remove local prefixes. Normalize from the complete source number and review a sample before submission.

What the result cannot prove

Registration or activity signals do not prove identity, marketing consent, purchase intent, or a fixed conversion outcome. Pictures, nicknames, age, and gender must not be expanded into unsupported sensitive inferences.

Delivery and review checklist

Keep the source TXT and exported Excel. Reconcile input and output rows, exceptions, and missing values. Record provenance, purpose, check date, access, and deletion timing. Review the current fields on the WhatsApp (WA/WS) service page.
