.post is a sponsored top-level domain (sTLD) available exclusively for the postal sector. .post is the first gTLD to be 100% secured by DNSSEC. .post 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. The domain was approved by ICANN on April 8, 2005 as a sponsored TLD in the second group of new TLD applications evaluated in 2004.
Having delegated authority for .post, the Universal Postal Union (UPU) develops, implements and monitors governance rules for it. It is also responsible for attributing domain names for postal-sector stakeholders who meet the eligibility criteria.
The UPU, based in Bern, Switzerland, became the first United Nations organization to be granted the right to operate a sponsored top-level domain (sTLD) by ICANN in 2004, in the first group of new TLD applications evaluated in 2004. The UPU was the only organization to pass all criteria by ICANN as a truly representative organization to sponsor a top-level domain.
In 2009, ICANN and the UPU signed an historic agreement giving the UPU managing authority over .post as a top-level domain. The agreement came about after long negotiations, public review through ICANN's public comment process, reviews within the UPU governing Councils and consideration by ICANN's Board of Directors.
The sTLD was added to the IANA TLD registry August 8, 2012 when .post entered the root of the internet.
.post was designed to serve the needs of the global postal community in cyberspace. The idea behind .post was to identify legitimate postal services and avoid confusion for individuals, business and stakeholders. Thus far, no major national postal service has used the suffix.
To register a .post domain, the UPU asks entities to submit a Community ID request (registration required) Registrants must be approved as being members of the.post Sponsored Community before registering domains. 
Prior to registering a .post domain, the UPU verifies the registrant's eligibility to register a domain name and issues a .post Community ID.
Each applicant is required to provide legal proof of ownership of the string, as well as falling into 1 of 11 Registrant Groups set out in paragraph 3.3 of the .post Domain Management Policy
