How much money can I add through PayPal CASH®?
You can usually add any amount from $20 to $500 per barcode. You may use up to three barcodes or add up to $500 total per day, whichever comes first. The amount of cash you can add may be reduced if there's additional activity on your PayPal account between the time you generate the barcode and when you use it.
PayPal limits you to adding $500 per day, and a total of $4,000 a month to your PayPal account. If you have reached either of these limits, you will not be able to use the PayPal CASH until the next day or month, when your PayPal limits reset.
