The .sh extension is the country-code domain of Saint Helena, a remote island in the South Atlantic Ocean. The same territory also includes Ascension and Tristan da Cunha, which lie far away in the same ocean. Local organisations, tourism providers and island projects may choose .sh to show where they are based. The availability form just below this text will show whether your name in .sh is still available.

A short history
Saint Helena is known to history as the island where Napoleon Bonaparte spent the last years of his life, and it has long been a stop for ships crossing the South Atlantic. The national code came with the island's arrival on the global internet. Since then the zone has been used by island services, businesses and community groups, and it is now a familiar part of how the territory presents itself online.
Who runs it
The zone is managed by a national registry that keeps the central database and sets the rules for registration. Registrars sell names to customers and send orders to the registry. Because the registry publishes its own conditions, check the current policy for holders, contact details and renewal before you pay, since the terms can differ from those of generic zones.
Rules in practice
- Holder conditions: the registry may set rules on who may hold a .sh name, so check them before you order.
- Contact details: the registration data must be accurate, and the registry may ask for it to be confirmed.
- Name format: names use letters, digits and hyphens, within the registry's length rules.
- Renewal: set the reminder early and keep a second person in the organisation informed about the expiry date.
Who uses .sh
- Tourism providers, guesthouses and tour guides who welcome visitors to the island.
- Local shops, cafes and craft makers that want an address rooted in the island.
- Schools, churches and community groups that share news with island residents.
- Researchers, conservation projects and visitor associations with an interest in the islands.
Strengths
- The ending states the link with Saint Helena in two letters, which is short enough for a sign, a boat name or a printed brochure.
- Search engines may read a country-code ending as one hint about the audience, so local pages may be easier to match with local queries.
- For a business whose customers are mostly on the island, the address tells the right story at once.
Things to keep in mind
- Some technical users know sh from the Unix shell, so the name may read differently to developers than to the general public.
- The zone is tied to one territory, so a business with a wider audience may also need a generic address.
- Many visitors do not know the ending, so the full address should appear clearly on every page and document.
- Holder conditions are specific to the zone, so review them before you transfer a name.
Tips before you register
- Look at the name in .com first and weigh whether you need both addresses.
- Use the official name of the business or project in all holder details.
- Describe the business in plain language on the first page, so visitors who do not know the zone understand the site.
- Set up SPF, DKIM and DMARC records before you use the domain for e-mail.
- Enable two-factor login on the registrar account and keep the recovery details current.
Frequently asked questions
Can a business outside Saint Helena register a .sh name? The registry sets the conditions for holders, so read the current rules before you apply.
Does .sh help a site rank in search? It can add a local hint, but the content, structure and links of the site matter much more.
Is .sh suitable for a technology project? It can be, but the ending may be read as a reference to the command line, so explain what the project offers on the first page.
