Cash App lets you send up to $250 within any 7-day period and receive up to $1,000 within any 30-day period. You can increase these limits by verifying your identity using your full name, date of birth, and the last 4 digits of your SSN. Cash App does not charge any fees for sending or receiving money, but it may charge fees for using a credit card, withdrawing cash from an ATM, or converting currency.
