How much money can I add to my PayPal account at a retailer?
When you add cash to your PayPal account at a retail store using a barcode, 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've reached either of these limits, you won't be able to add cash until the next day or month, when your PayPal limits reset.
