Prepare input
Keep the source identifier, use one record per row and verify the format with a small sample before a larger task.
LINE Screening for Account presence & Activity signal
Use NumSift to prepare LINE contact datasets for service operations in Japan, Taiwan and Thailand without mixing unrelated platform fields. Review country formatting for Japan, Taiwan and Thailand separately; a LINE account signal should not be interpreted as general phone reachability.

PRODUCT SCOPE
What LINE screening is designed to do
LINE account screening for prepare LINE contact datasets for service operations in Japan, Taiwan and Thailand without mixing unrelated platform fields.
Choose signals
This page focuses on Account presence, Activity signal, Profile availability, Ecosystem association, rather than applying unrelated fields from another product.
Keep context
Export task time, unknown values and exception states so the result remains reviewable.
SUPPORTED CAPABILITIES
Screening capabilities covered for LINE
Fields can vary by task. Select only the capabilities the workflow needs and validate a small batch before submitting a full dataset.
LINE Account presence
Classify available account-presence signals, unresolved records and task exceptions without treating them as phone validity.
Result groupaccount status, unresolved state and task status
LINE Activity signal
Keep the task timestamp beside any available activity signal so teams can judge how current the result is.
Result groupactivity band, observation time and unknown value
LINE Profile availability
Organize returned profile fields while preserving empty and unknown values for later review.
Result groupavailable profile fields and empty-field state
LINE Ecosystem association
Classify records by the ecosystem signals returned by the selected task and retain incompatible states.
Result groupecosystem state, compatibility and exception status
RESULT GROUPS
What the output should make clear
Every result group should remain linked to its source record. Unknown, empty and task-exception values should stay separate instead of being converted into a negative result.

THREE-STEP WORKFLOW
From source data to reviewed LINE results
Prepare and sample
Preserve source values, normalize obvious format differences, remove exact duplicates and prepare a small sample.
Select the required capabilities
Choose the required items from Account presence, Activity signal, Profile availability, Ecosystem association; avoid adding fields the decision will not use.
Review and export
Check field meaning, task time, unknown values and exceptions before importing structured output into another system.
PRACTICAL USE
Where LINE screening fits
Regional customer care
Create a dedicated LINE dataset for regional customer care, with source identifiers and task timestamps kept beside every result.
Decide how to build a cleaner LINE service-contact segment
Use account presence, activity signal, profile availability, ecosystem association as separate review fields so one missing value does not erase the rest of the record.
Prepare LINE exports for downstream review
Export the original identifier, selected result fields, unknown values and exception states together so another team can reproduce the decision.
FAQ
LINE screening questions
What does the LINE account screening page cover?+
It explains how to prepare LINE contact datasets for service operations in Japan, Taiwan and Thailand without mixing unrelated platform fields, including the supported signal groups, input preparation, result interpretation and review boundaries.
What input should I prepare for LINE screening?+
Prepare authorized phone or account records. Keep one source record per row, preserve the original value and normalize obvious formatting differences before a larger task.
Which LINE results can be organized?+
This product page covers account presence, activity signal, profile availability, ecosystem association. The exact fields available depend on the selected task and may include unknown or empty values.
How should I use LINE screening results?+
Use them to build a cleaner LINE service-contact segment. Check task time, field meaning and exception states before importing results into another system.
Does LINE screening prove consent or identity?+
No. Screening organizes returned technical or account signals. It does not prove a person's identity, create marketing consent or replace the rules that apply to the source data.
