Viber Number Format Guide: Country Codes and TXT Normalization: verified scope, keywords, TXT input, Excel fields, and product boundaries.
Viber number normalization should use source-country information and preserve the international code rather than guessing from length.
Direct answer
Viber number normalization should use source-country information and preserve the international code rather than guessing from length.
Map keywords to the task
Remove spaces, brackets, hyphens, names, and notes, deduplicate, and save one number per line in TXT. Use Number Checker as the primary English term for 筛号, while registration, activity, formatting, and profile tasks remain distinct.
Prepare TXT input
Verify source and country code, deduplicate, remove formatting characters, names, and notes, and save one phone number per line in TXT. Excel and CSV are not accepted upload formats.
Read the Excel output
Viber Registration Check returns phone number and registration status. Activity Check may return active days, mid, and offline time; profile tasks are selected separately.

When execution is needed, select the matching task on the AIPushAI Viber service page. The brand link points to a real capability rather than replacing methodology or evidence.
What the result cannot prove
Registration or activity does not prove identity, marketing consent, purchase intent, or a fixed conversion outcome. Keep missing values unknown and store the check date.
When to run another check
Number status can change, but repeated checking needs a current business purpose. Recheck a Viber list only when the relationship remains valid, the result will affect an active workflow, and the previous check date is no longer suitable. Do not recheck opted-out or expired records.
Acceptance checklist
Test a small sample, reconcile input and output rows, exceptions, mapped numbers, and Excel columns, preserve raw TXT and Excel, and import through the original number or an internal ID.
