If the EPP key provided was correct, then the transfer will immediately be initiated. If the EPP was incorrect, you will receive an email on the account’s administrative email address that should be used to confirm the domain transfer.
The transfer request could also require the domain owner’s authorisation. If the transfer request is approved by the current owner, the transfer will proceed. Should approval not be obtained within a specific period as defined by the current Registrar, the domain transfer will be cancelled and the transfer process will need to commence again.
Depending on the type of domain name and its current registrar, the domain name transfer service could be immediate in the case of .za domains, or can take up to 5-14 days to complete properly.
