WhatsApp international number converter
Convert a local number to the international format accepted by WhatsApp (country+area+number). Support for Brazil, USA, Spain, Mexico, Portugal and more.
WhatsApp requires international format without spaces or special characters. Enter the number as typed (with or without dashes), select the country, and get the format ready for wa.me links, campaigns, and automation tools.
Why International Format Matters
For link wa.me to work, the number must be in international format without spaces, parentheses or plus signs. This format combines three parts: DDI (country code), DDD (area/city code) and the number.

Common errors in conversion
- Leave the plus sign (
+55instead of55). - Keep parentheses or hyphens of the local format.
- Forget the DDD in Brazilian numbers (without it, the link does not work).
- Confuse DDI with DDD (DDI is country, DDD is city).
- Use 9 digits without the initial 9 on a new Brazilian cell phone.
