ICANN will hold WHOIS accuracy audits later this year. Accredited registrars will each be subject to an anonymous ICANN audit of their domain names. Names breaching the WHOIS requirements (inaccurate or incomplete entries) will be reported via WDRPS. ICANN will then double check the WHOIS 45 days later. Registrars with names still in breach of the WHOIS requirements will be notified of a failure to comply with Section 3.7.8 of the Registrar Accreditation Agreement (RRA) with an explanation expected within 5 business days.
