ICANN: New Report Presents Syntax and Operability Accuracy of WHOIS Data in gTLDs

ICANN logoICANN today (12 June) published the WHOIS Accuracy Reporting System June 2017 report. This latest report of the WHOIS Accuracy Reporting System (ARS) acts as a follow-on to the reports published in December 2016, June 2016, and December 2015.

Read the Report.

The report explores both the syntax and operability accuracy of WHOIS records in gTLDs as compared to the requirements of the 2009 and 2013 Registrar Accreditation Agreements (RAAs). It also examines the leading types of nonconformances, trends and comparisons of WHOIS accuracy across ICANN regions, RAA versions and gTLD types.

ICANN developed accuracy tests to answer questions about the syntax (format and content) and operability (e.g., does an email sent to the email address provided in the WHOIS record go through?) of a sample of WHOIS records. Then, using statistical methods, syntax and operability accuracy estimates with a 95 percent confidence interval were provided for the population of domains in gTLDs as a whole, as well as for several subgroups of interest.

Key Findings

The analysis found that:

  • Nearly all WHOIS records contain information that can be used to establish immediate contact: In 98.6 percent of records, at least one email or phone number meets all operability requirements of the 2009 RAA.
  • Approximately 94 percent of email addresses, 69 percent of telephone numbers and 97 percent of postal addresses were operable (see Table 1 below for more information).

Table 1: Overall gTLD Operability Accuracy by Contact Mode (95 percent confidence interval)

Email Telephone Postal Address All 3 Accurate
All 3 Contacts (Registrant, Technical, Administrative) Accurate 94.5% ± 0.5% 68.9% ± 0.8% 97.2% ± 0.3% 65.4% ± 0.9%
  • In terms of syntax accuracy, approximately 99 percent of email addresses, 90 percent of telephone numbers and 87 percent of postal addresses were found to meet all the requirements of the 2009 RAA (see Table 2 below for more information).

Email Telephone Postal Address All 3 Accurate
All 3 Contacts (Registrant, Technical, Administrative) Accurate 99.5% ± 0.1% 89.5% ± 0.6% 87.4% ± 0.8% 79.3% ± 0.8%

The report also shows a breakdown of accuracy rates by ICANN region (see Figure 1 below for more information).

Next Steps

Results included in the report have been provided to ICANN‘s Contractual Compliance team, which will assess the types of errors found and follow up with registrars on potentially inaccurate records. If WHOIS inaccuracy and/or format complaints are created from the WHOIS ARS data, ICANN Contractual Compliance will issue tickets in accordance with the Contractual Compliance Approach and Process [PDF, 292 KB]. Compliance provides updates on a quarterly basis, which include updates on WHOIS ARS tickets and can be found here. In response to ICANN community requests, ICANN now publishes additional metrics on the WHOIS ARS Contractual Compliance Metrics page here.

ICANN will begin work on the next WHOIS ARS report in July 2017, with a targeted publication date of December 2017.

ICANN will host a webinar in July (date TBD) to review methodology and findings of the report.
