.mutual domain extension

.mutual is a generic top-level domain that was originally intended for use by mutual insurance companies and related organizations. It was sponsored by Northwestern Mutual MU TLD Registry, LLC, a subsidiary of the Northwestern Mutual life insurance company. The domain was delegated in March 2016 but never appeared in the root zone. It was revoked in August 2023, meaning it is no longer available for registration or use. The TLD was part of a wave of brand-specific domains approved by ICANN, but it never became operational.

The .mutual domain was delegated on March 29, 2016, to Northwestern Mutual MU TLD Registry, LLC. It was one of many new gTLDs applied for during ICANN's 2012 expansion. However, the domain never made it into the root zone, and its delegation was revoked on August 1, 2023. The reasons for the revocation are not specified in the IANA record, but it likely stemmed from the registry's failure to meet operational requirements or a decision to abandon the project.
