These are the same South African mobile in each format. The example is a reserved test number from Google’s libphonenumber metadata, so it is structurally correct without belonging to anyone.

The rule for South Africa

South African numbers use a leading 0 domestically that must be dropped. Because they are always ten digits with the zero and nine without, a count of nine digits after 27 is a good sanity check.

  1. Start with the local number. 071 123 4567
  2. Apply the South African rule. Remove the domestic dialling prefix shown above.
  3. Add the country code. Put 27 in front, giving 27711234567.
  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 South African 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 South African number for WhatsApp?

Write 27 followed by the subscriber number, digits only, with no plus sign, spaces or dashes. A South African mobile written locally as 071 123 4567 becomes 27711234567, giving the link https://wa.me/27711234567.

What is the WhatsApp country code for South Africa?

South Africa uses country code +27. In a wa.me link the plus sign is dropped, so the link starts https://wa.me/27.

Do I remove the leading zero from a South African number?

Yes. The leading digit used for dialling inside South Africa is not part of the international number and must be removed before the country code is added. 071 123 4567 becomes 27711234567, not 270711234567.

Can I message a South African 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 South African 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 27711234567 first: the most common cause here is keeping the leading zero.
