Universal Acceptance Roadmap for Domain Name Registry and Registrar Systems

31 August 2022

The Universal Acceptance (UA) Roadmap for Domain Name Registry and Registrar Systems proposes how to test these systems for UA readiness based on the Universal Acceptance Readiness Framework. A registry and registrar system were tested, and the results are reported in appendices. The study is published for review and feedback by the relevant technical community.

Proposals for Your Input


The concept of Universal Acceptance conveys that all software applications support all valid domain names and email addresses. This study focuses on the technical details for the systems used by registries and registrars to manage domains under generic top-level domains. This work follows up on the white paper "The Role of Country Code Top-Level Domains (ccTLDs) in Achieving Universal Acceptance," published by the Asia Pacific Top Level Domain Association in collaboration with the ICANN organization. It may generally apply to the ccTLD registry and registrar environments as well.

Next Steps:

The UA roadmap will be finalized based on the input received and published for reference of domain name registries and registrars. The roadmap will be shared with relevant stakeholders to encourage them to become UA ready.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a nonprofit public benefit corporation with a community of participants from all over the world.
