The rule for Brazil

Brazilian mobile numbers carry an extra 9 in front of the eight-digit subscriber number, after the two-digit area code (DDD). A São Paulo mobile is 11 9XXXX-XXXX. Older numbers written without that 9 are landline-era formats and will not open a WhatsApp chat.

  1. Start with the local number. (11) 96123-4567
  2. Apply the Brazilian rule. There is no prefix to remove, so the digits stay as they are.
  3. Add the country code. Put 55 in front, giving 5511961234567.
  4. Build the link. Append the digits to https://wa.me/ with nothing between them, or use the generator and let it handle the formatting.

Does a valid number mean the person is on WhatsApp?

No. Everything above concerns format, which is a separate question from whether an account exists. A correctly formatted Brazilian number can belong to a landline, to a newly issued SIM, or to someone who has deleted their WhatsApp account, and in each case the link will open and report that the number is not on WhatsApp.

To find out, open a chat link for the number and see whether WhatsApp starts a conversation.

How do I write a Brazilian number for WhatsApp?

Write 55 followed by the subscriber number, digits only, with no plus sign, spaces or dashes. A Brazilian mobile written locally as (11) 96123-4567 becomes 5511961234567, giving the link https://wa.me/5511961234567.

What is the WhatsApp country code for Brazil?

Brazil uses country code +55. In a wa.me link the plus sign is dropped, so the link starts https://wa.me/55.

Do I remove the leading zero from a Brazilian number?

There is nothing to remove. Brazilian numbers have no domestic trunk prefix, so the digits you use locally are the same digits that follow the country code. (11) 96123-4567 becomes 5511961234567.

Can I message a Brazilian number without saving it?

Yes. Open https://wa.me/ followed by the number in international format and WhatsApp starts the conversation without adding a contact. Recent versions of WhatsApp can also do this by typing the number into the new-chat search.

Why does my Brazilian WhatsApp link say the number is invalid?

Either the number is formatted wrongly or it has no WhatsApp account, since WhatsApp shows the same message for both. Check the digits against 5511961234567 first: the most common causes are a missing country code or a stray plus sign.
