Can I generate a IBAN number from my Payoneer GBP Receiving Account's sort code?

Hi, the Amazon's KDP asks me to input the IBAN and BIC into my UK bank account information. But what I have from Payoneer is the a Barclays account's sort code and account number. I have done some research and found that the Barclays have a page for generating the IBAN. The current problem is that the page only generate IBAN for sort code starting with 20, not 23 that I have from Payoneer. So the question is, can I (or how can I) obtain an IBAN for my GBP Receiving account so I can input the code into my KDP's UK bank info?
