WhatsApp number format explained

WhatsApp works best with numbers in E.164 format: a leading plus sign, country code, and full national number with no spaces. Example: +15551234567.

Why number validation matters

Invalid formatting causes failed links, broken automations, and missed conversations. This tool standardizes your list before you use it in links, QR codes, forms, or API workflows.
