WhatsApp checker Brazil — bulk +55 number checks
Brazil is WhatsApp-first. Bulk-validate +55 mobiles, activity days and carrier. CSV export on Checkfast.pro.
Brazilian lead ops almost always start with WhatsApp. Local 11-digit mobiles must keep country code 55. Mix DDD (11, 21, 31…) in one file is fine as long as every line starts with 55.
Use cases
- CPA / gambling / e-com lists: drop numbers without WhatsApp
- WhatsApp Days checker for recency before broadcast
- Brazil carrier lookup (brcarrier) for mobile vs VoIP
- Facebook as a second social filter on the same file
