What is .post?

.post is the sponsored top-level domain (sTLD) on the Internet exclusively created for the postal sector. .post makes it easier to locate and identify postal entities on the Internet.

The domain is a secure, stable and trusted Internet infrastructure, aimed at serving the needs of the global postal community and providing postal services to citizens of UPU member countries. 

.post is the standard identifier for the postal community in cyberspace, giving its members a unique identity that clearly differentiates them from non-postal entities currently using “post” in their URLs. 

What is a sponsored top-level domain?

A sponsored top-level domain (STLD) has a sponsoring organization representing a well-defined community. The Internet Corporation for Assigned Names and Numbers (ICANN) delegates the responsibility for formulating policies regarding various matters concerning the STLD to the sponsor.

ICANN is an internationally organized, non-profit corporation responsible for overseeing the organisation of the Domain Name System (DNS) – generally known as the internet.

STLDs include .edu, .gov, .int, .post, .jobs, .mobi, .aero, .museum and are restricted to specific types of registrants. There are 22 STLDs, including .post.

The core group of generic top-level domains include .com and .org.

What is the UPU’s role as the sponsoring organization behind .post ?

The UPU is managing .post for the benefit of the postal community. The Internet Corporation for Assigned Names and Numbers has delegated the responsibility of developing, implementing and enforcing policies related to the domain to it.

The UPU sees .post as an excellent opportunity to provide the security and trust that governments, businesses and citizens demand before they increase business and financial transactions over the internet.

As the specialized agency of the United Nations responsible for international postal services, the UPU represents 192 member countries and promotes universal postal services in both the physical and electronic world.

The organization has been a forum for cooperation between governments, Posts and other stakeholders of the worldwide postal sector since 1874.

Why is the .post platform important for the future?

A recent UPU survey shows that Posts worldwide have developed at least 55 types of postal e-services over the past 20 years and consider them to be strategically important to their future.

There is no doubt that postal e-services will continue to develop and the UPU’s latest world postal strategy takes this important development into account.

The .post platform is readying the UPU, its member countries and postal stakeholders for the future.

What will the .post platform do that existing websites and domains cannot do?

Many Posts have indeed developed several electronic services successfully. These services are being used domestically for the most part.

But with globalization, cross-border opportunities in areas such as e-commerce and others are developing. Issues of authentication, security, e-payment and more abound.

A global .post platform supporting electronic postal services with international standards and regulation will facilitate their extension to other countries.

Why is a .post domain considered more secure than other domains?

.post is the first sponsored top-level domain to utilize Domain Name System Security Extensions (DNSSEC), a set of codes for securing the Domain Name System (DNS), the global database system that translates a computer's fullyqualified domain name into an Internet Protocol (IP) address.

The security extensions help to prevent phishing and other cybercrimes by signing and authenticating legitimate websites. Public key cryptography is incorporated into the DNS hierarchy to form a chain of trust originating at the root zone.

DNSSEC is crucial to the .post platform, as the UPU aims to build a secure and trusted space on the internet for e-commerce, e-government and electronic postal services provided by the postal industry.

Using .post DNSSEC domain names is crucial for any postal organization that conducts highly sensitive data transactions on their websites or wants to ensure traffic to their legitimate website and not a scam one.

What benefits could .post generate?

There are a number of benefits. Searching for postal services on the internet will become easier. A bridge could be created between traditional physical mail services and new electronic ones.

The domain could facilitate the entry of developing countries into the realm of electronic postal services.

New services can be developed and offered in a secure environment across borders. The postal brand will be strengthened and modernized and made instantly recognizable on the web.

E-commerce can benefit from an additional level of trust offered by .post.

What kind of applications could I use on .post?

Typical applications cover e-post, e-commerce and e-government and include the following types of applications:

Electronic communication applications

  • Registered electronic letter
  • Electronic mailbox
  • Hybrid mail


  • Universal Web postal address (mapping electronic and physical addresses)
  • Change of address


  • Philately e-shop


  • Track and trace


  • E-voting
  • E-learning


  • Electronic money transfer

Have there been any pilot projects developed with .post to test its applications?

The first .post application piloted by the UPU is International Registered e-Mail (IRM). The service was trialled between Poste Italiane and the Posts of China and Macau. The UPU has also created a global track and trace application. Once fully implemented, it will enable customers to track the items they have ordered until final delivery. Using the electronic data that the world’s Posts exchange on the UPU’s Post*Net network and other interconnected networks managed by external partners, all designated operators could benefit from a comprehensive end-to-end track and trace system, bringing value to online merchants and customers alike. Such a service will also be very useful for a global service such as EMS under ems.post.

.post can link domestic services, such as registered post or parcels, into a global network of similar services and open up new markets and customers for these services.

Who can apply for a .post domain?

The .post registry is currently accepting registrations from qualified organizations within the .post-sponsored community. Prospective applicants for .post domains have to belong to a pre-defined group from the postal community. The main ones are the UPU, its member countries, restricted unions and designated operators.

Other postal-sector members may also apply, providing they are authorized by the UPU to do so. These can be non-designated operators and communications entities supporting the delivery of postal services.

UPU members or restricted unions can apply directly at https://apply.info.post.

Other organizations such as direct marketing and hybrid mail vendors, logistics companies, payment providers and educational institutions may also be able to register .post domains in the future. Check www.info.post for details on when the next phase of registrations will be opened.

All current registrations are being processed by the UPU, which is acting as a registrar. The registrars necessary to operate the .post platform will be selected by the second half of 2013.

How can one register .post domains?

To register a .post domain, please submit a community ID request.

To verify your eligibility to register a domain name and to issue a .post community ID, the UPU goes through a verification process, for which each registrant is charged an authentication fee of 10,000 CHF per year. Members of the .post group do not pay this fee. If you would like to join the .post Group, please contact us at dotpost@upu.int.

Upon receipt and verification of your request and the supporting documents, we will send you an invoice. Once the payment has been processed, we will issue the community ID and you can register your .post domain names.

Note that prior to your .post domain name registration, you must provide legal proof of ownership of the string being applied as mentioned in paragraph 3.3.1. of the .post Domain Management Policy.

What is the price of .post domains?

The UPU Postal Operations Council is responsible for setting the wholesale price to cover the cost of operation of .post. The price is 700 CHF per domain name per year. 

As the sponsor, the UPU sets eligibility policies for registration of .post domain names based on the criteria defined in the agreement with ICANN. Eligibility criteria are specified in the .post Domain Management Policy. The UPU will validate that each registrant is a member of the postal community and meets the eligibility criteria. Therefore, in addition to the domain name fee, the registrant pays an authentication fee of 10,000 CHF per year.

The minimum domain name registration period is for two years and registration fees are not refundable once your domain name has been submitted.

Why is .post more expensive than a domain name such as .com?

UPU is required by both ICANN and the postal community it represents, to maintain the integrity of .post to ensure that it is a trusted domain for postal business.

Unlike very generic top-level domain names, the integrity of .post is maintained through verification of all applicants who submit a .post domain name request. UPU verifies each potential .post registrant and ensures that they are a valid member of the postal community. This verification significantly decreases the volume of speculative registrations and cybersquatting, but generates a cost.

Although it has an impact on the price of a .post domain name, it is thanks to this process that .post benefits from the support of  the postal industry and the UPU members.  .post names are priced as affordably as possible to allow postal sector organizations to get the names they need to maintain a strong web presence.

How can I check the availability of a domain name?

Simply type the domain name you are interested in with its .post extension in the WHOIS search capability to see if it is available for registration.  

.post WHOIS contains information on all registered and reserved .post domain names.

Has the UPU reserved any premium names?

The list of reserved names is in “Table 3 – List of reserved community- and industry-specific names” of the .post domain management policy.

Are there any protection mechanisms for IP in case my trademark is already registered as a .post domain by another entity?

Yes. The .post domain names are subject to the standard ICANN Uniform Dispute Resolution Policy (UDRP) provided by World Intellectual Property Organization. This provides a procedure for resolving certain trademark disputes relating to domain names.

What is a registrar?

A registrar is any company accredited by ICANN and selected by the UPU to register and maintain domains on behalf of its customers.  There are more than 900 ICANN-accredited registrars who provide domains to Internet users. List of ICANN-accredited registrars

The registrar asks applicants, or “registrants”, various contact, technical and billing information that makes up the registration. The registrar maintains records of the contact information and submits the technical information to the "registry".  The registry provides other computers on the Internet the information necessary to send the registrant e-mail or to find the registrant’s website.

What is a registry?

The registry is the authoritative, master database of all domain names registered in each top-level domain such as .post. The .post registry operator is Afilias. It keeps the master database and also generates the zone file, which allows computers to route Internet traffic  to and from top-level domains anywhere in the world.
