The .aero zone is a sponsored extension set up for the air transport industry, and its name comes from the word aero, which relates to aircraft and flight. Registration is restricted to the aviation community, so a name may be available to register without you being eligible to hold it. Use the availability form just below this text to see whether your name in .aero is still available, and then check the eligibility terms.

A short history
The .aero zone was one of the earlier sponsored extensions, created to serve a single industry rather than the general public. Since then it has been used by organisations linked to flight, from maintenance and training businesses to airport service companies. Its use stays closely tied to the sector it was designed for, which gives it a focused character that a generic ending does not have.
Who runs it
A sponsored zone has a sponsoring organisation that sets the policy for its community. The registry carries out the day-to-day work of keeping the database and processing orders, and registrars handle requests from customers. The sponsor's current policy decides who may register and which names are acceptable, so read it in full before you start shortlisting names.
Rules in practice
- Eligibility: registration is limited to members of the air transport community, and the current policy sets out who qualifies.
- Names: names follow the general DNS rules, using letters, digits and hyphens, with up to 63 characters for each label.
- Changes: if your business or your role changes, the registration details may need updating, so keep them current.
- Renewal: set reminders and check whether your registrar supports automatic renewal for this zone.
Who uses .aero
- Aircraft maintenance and repair businesses that serve airlines and private operators.
- Airport services, ground handling and aviation logistics companies.
- Flight training schools and aviation colleges that teach pilots and engineers.
- Industry associations, trade publications and conference organisers in aviation.
Strengths
- The ending tells people in the industry that the site belongs to the air transport community.
- A focused zone can help a sector website look credible to partners and customers who know the field.
- The name is short and easy to spell, which helps on a technical manual or a trade show banner.
Things to keep in mind
- Restricted zones are not open to everyone, so a name that appears available may still be out of reach if you do not meet the criteria.
- Outsiders may not recognise the ending, so explain the zone on your about page.
- Aviation has strict safety and regulatory rules of its own, and a domain name does not change them.
- Keep the registration contact details aligned with your official company records.
Tips before you register
- Read the current eligibility terms before you spend time on a shortlist of names.
- Check the name in .com, since many visitors may still type that address.
- Use the company name exactly as it appears in your official records.
- Publish clear contact details for sales, technical support and press enquiries.
- Set up mail authentication records and protect the registrar account with two-factor login.
Frequently asked questions
Can any company register a .aero name? No. Registration is limited to the air transport community, so check the current eligibility rules before you order.
Does a .aero domain prove that a company is an approved aviation business? No. A domain name is an address, and it does not confer approval, licences or certification.
Is .aero useful for a company outside aviation? The zone is tied to its industry and its eligibility rules are narrow, so a company outside aviation would normally need a different ending.
