About .post domain
.post is a sponsored top-level domain (sTLD) managed by the Universal Postal Union (UPU), a specialized agency of the United Nations headquartered in Bern. ICANN approved the extension in April 2005 during its second round of new TLD evaluations, and the domain was formally delegated to the IANA root zone on August 7–8, 2012. The registry backend is operated by Afilias. The UPU holds full managing authority over .post, developing and enforcing eligibility rules, verifying registrant qualifications, and issuing Community IDs required before any domain can be registered.
Who can register .post domain
Registration of a .post domain is restricted exclusively to members of the .post Sponsored Community — it is not open to the general public. Before registering, each applicant must submit a Community ID request to the UPU, which verifies eligibility and issues a .post Community ID as a prerequisite. Applicants must provide legal proof of ownership of the desired string and must fall into one of 11 defined Registrant Groups outlined in the .post Domain Management Policy. Eligible registrants include UPU member postal operators, post offices, and postal-sector-related organizations. Following a policy update, private-sector organizations involved in postal and supply chain solutions — such as logistics, track-and-trace, identity, cross-border payments, and blockchain applications — are also eligible to apply.
How to register .post domain
Because .post is a restricted sTLD allocated through the Universal Postal Union's own eligibility and verification process, domains are not registered through the standard commercial registrar checkout flow. Prospective registrants must first contact the UPU directly and submit a Community ID request, demonstrating that they qualify under one of the 11 recognized Registrant Groups in the .post Domain Management Policy. The UPU reviews the application, verifies legal proof of ownership of the desired string, and — if approved — issues a .post Community ID that authorizes the registrant to proceed with domain registration. The UPU itself oversees the attribution of domain names to approved stakeholders and monitors compliance with its governance rules on an ongoing basis.
Typical uses of .post domain
.post domains are used primarily by national postal operators, post offices, and postal-sector organizations to establish a verified, trusted online presence distinct from generic domain extensions. Early adopters included postal services in Italy, Brazil, and Malaysia, which used their .post addresses to offer web interfaces for traditional services such as letter and parcel delivery, as well as advanced offerings like Postal Registered Electronic Mail (PREM). Organizations in the postal sector choose .post to signal authenticity and legitimacy to customers, since the extension's strict eligibility requirements make it a recognized mark of genuine postal affiliation.
Tips for registering .post domain
- Eligibility verification comes before registration: the UPU must issue a .post Community ID to the applicant before any domain name can be formally registered, so factor this approval process into your timeline.
- Legal documentation is mandatory: applicants must supply legal proof of ownership or entitlement to the specific string they wish to register, so prepare corporate or organizational documents in advance.
- The .post Domain Management Policy defines 11 distinct Registrant Groups; confirm which group your organization falls into before submitting your Community ID request to avoid delays.
- Following a policy revision, private-sector companies providing postal and supply chain solutions — including logistics, track-and-trace, and cross-border payment services — became eligible, broadening the pool of potential registrants beyond traditional postal operators.
- Dispute resolution for .post domains follows the UDRP (Uniform Domain-Name Dispute-Resolution Policy), the standard ICANN mechanism for resolving trademark-based domain disputes.
