US and Canadian operators/carriers will not support Sender ID’s that are a custom word (Alphanumeric Sender ID) due to restrictions on brand name usage known as ‘spoofing’.
A pre-registered short code or long code can only be used as a Sender ID in the US and Canada.
Please refer to the article on Laws and regulations in US & Canada for further information.
Alternatively, create a ticket to our Support Team who will further assist you in finding the best possible option to use as your Sender ID in the US and Canada.
