About .post domains

.POST is a top-level domain delegated in the IANA root zone. See the official IANA delegation record for manager and technical contacts.

.post is a sponsored top-level domain (STLD), available exclusively for the postal sector, and is secured by DNSSEC. The domain aims to integrate the physical, financial, and electronic dimensions of postal services to enable and facilitate e-post, e-finance, e-commerce, and e-government services. ICANN approved the domain on April 8, 2005, as a sponsored TLD in the second group of new TLD applications evaluated in 2004. In 2004, the Universal Postal Union (UPU), based in Bern, was the first United Nations agency to secure a top-level domain (TLD) from ICANN. In 2009, ICANN and the UPU signed a historic agreement, giving the UPU managing authority over .post as a top-level domain. The agreement came about after negotiations and public review through ICANN's public comment process, reviews within the UPU governing councils, and consideration by ICANN's Board of Directors. Having been delegated authority for .post, the UPU develops, implements, and monitors government rules for it. It is also responsible for attributing domain names to postal-sector stakeholders who meet the eligibility criteria. The STLD was added to the IANA TLD registry on August 8, 2012.
