WhatsApp number validator best practices (2026): batching, stability, clean exports
Marketing Wala Pakistan • Jan 2026
The 6 rules we recommend
- Normalize numbers with country code formatting.
- Remove duplicates before validation.
- Validate in batches (don’t overload one run).
- Use consistent export naming (date + batch + status).
- Keep sessions stable (avoid multitasking in Chrome during long runs).
- Keep outreach compliant and lawful.
What to export
For teams, exports should be simple and consistent. A good export set includes separate files for valid, non-active, and duplicates so your follow-up team doesn’t waste time.
