For a non KYC Amazon Pay wallet the monthly limit for adding money is ₹10,000 and the total balance in the wallet also cannot go beyond ₹10,000 at any point. This is an RBI restriction on minimum KYC wallets so once you hit that limit the system will block further loads. If you tried adding with your ICICI Amazon Pay card and it failed, it’s most likely because your wallet already reached the cap and not an issue with the card itself. To get higher limits you need to complete full KYC where the balance can go up to ₹1 lakh and monthly loads are allowed accordingly.
