DDI
Country code (Brazil = 55) required in any wa.me link and in international messages — without it, the link will not work.
IDD (International Direct Dialing) is the country code, needed in any link wa.me and in international messages via WhatsApp. Without the correct DDI, the link does not work or opens in the wrong conversation.

DDI vs DDD: not to be confused
DDI = country code (Brazil = 55). DDD = area/city code (São Paulo = 11). In the wa.me link, both are concatenated without spaces: 55 (DDI) + 11 (DDD) + 987654321 (número) = 5511987654321.
Common errors
- Forget the DDI on Brazilian numbers — link does not work on international calls.
- Add plus sign (
+55) — wa.me does not accept. - Confuse DDI with DDD (DDD comes later).
- Using the wrong DDI due to confusing country (Argentina = 54, not 549; 549 is an old extension).
