Registrar-Lock

REGISTRAR-LOCK is a status code that can be set on an Internet domain name by the sponsoring registrar of the domain name.^[1][2] This is usually done in order to prevent unauthorized, unwanted or accidental changes to the domain name.

When set, the following actions are prohibited by the domain name registry:

• Modification of the domain name, including:
  • Transferring of the domain name
  • Deletion of the domain name

Renewal of the domain name is, however, still possible when REGISTRAR-LOCK is set.

Not all TLDs support REGISTRAR-LOCK, e.g. .org.uk, and others. The .CA TLD added support for REGISTRAR-LOCK in October 2010.

RFC 2832, Section 6 and RFC 3632 section 2.1 lists the different status codes and their descriptions.
