Transfer lock policies can differ at each domain registrar. Depending on the situation and domain name status, some locks are required by ICANN and others are suggested by the organization.
Some registrars are more lenient with transfer locks that aren’t required by ICANN and others are more rigid. Some registrars will lock a domain name for 60 days after a Whois or account change and others will allow that lock to be lifted when requested. Most registrars will lock domain names after an inbound transfer, but some will lift it situationally. All newly registered domain names are required to be locked for 60 days after registrations.
