A registrar may determine a registration status for a domain names. The registrar may determine whether the domain name is in a zone file downloaded from a registry. Upon determining that the domain name is not in the zone file, the registrar may determine whether the domain name is in a DNS zone file created by the registrar. Upon determining that the domain name is not in the DNS zone file created by the registrar, the registrar may transmit an EPP command for the domain name to the registry. The registrar may receive a first EPP element comprising an error indicating the domain name is available or a value indicating the domain name is not available. Upon receiving the value indicating the domain name is not available, the registrar may transmit an EPP command for the domain name to the registry. The registrar may receive a second EPP element from the registry comprising an expiration date and a state of the domain name.
