The length of the short code is also depending on the country restrictions. Usually it is between 3 and 6 digits. Don’t put any + in front and only use digits!

An alpha numeric sender ID can contain letters, spaces, digits and special characters, like –,_,&,,,|,+. The maximum length of an alpha numeric sender ID is 11 characters. Not every country and network support alpha numeric sender IDs and also not each special character is supported everywhere.
