W8 BEN or w9

Hello,

I was non resident alien from 2015 to 2019 and filled 1040NR for 2015 to 2019 tax years. From year 2020 , I became resident alien. I filed 1040 for year 2020. I will be resident alien for future tax purpose also. My bank is asking me to fill W8 BEN form . Am I supposed to fill W8 BEN or W9.

Thanks
