|---|---|
| International | +1 201 555 0123 |
| In a wa.me link | 12015550123 |
The rule for United States
US and Canadian numbers share country code 1 and have no trunk prefix to remove — the ten digits you dial domestically are the ten digits you use internationally. There is no way to tell from the number alone whether it is a mobile that can receive WhatsApp or a landline that cannot.
How to build a US WhatsApp link
- Start with the local number. (201) 555-0123
- Apply the US rule. There is no prefix to remove, so the digits stay as they are.
- Add the country code. Put 1 in front, giving 12015550123.
- 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 US 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.
