Yeah, Cash app has a limit to send money. You can spend up to $250 in a week and up to $1000 in a month. If you want to exceed this amount limit, then you have to provide your SSN here. Basically, once you are going to exceed the amount limit, then a new window will be open where you have to put all the details to identify yourself.
