Ionut You are a brand new user. This is the public community forum, so we do not have insight into your account, but first you need to make sure that you have successfully completed your identity verification. If that step is already done for you, then your IBANs will be immediately valid. However, other banks might take a little while before they update their databases. You should allow for a few business days until all European banks should be able to send payments to your account successfully.
