The .co.ua extension is a second-level zone inside Ukraine's national domain .ua. The "co" part is a common shorthand for company, so the ending suits businesses and projects that want a Ukrainian address with a commercial character. Use the availability form placed after this paragraph to check whether the name you want is still free.

A short history
The Ukrainian national domain .ua was created in the early days of the internet. Over time the registry opened a set of second-level zones, each intended for a different kind of organisation, and businesses began to use these zones alongside .com.ua and .ua. The zone .co.ua is one of those options, chosen by Ukrainian companies and projects that wanted a short and business-like name.
Who runs it
The zone is part of the Ukrainian domain name system. Accredited registrars sell the names, while the zone operator keeps the central record of who holds which domain and sets the rules for registration, including the data a holder must provide. Those rules are the reference point for any question about a name, so read the current terms of the zone before you order.
Rules in practice
- Holder data: the registry expects accurate information about the holder, and it may check it.
- Length rule: up to 63 characters per label, using letters, digits and hyphens only.
- Deadlines: renew the name before the expiry date, because a lapsed name can be released to other customers.
- Internationalised names: ask your registrar whether such names are offered in this zone before you plan around them.
Who uses .co.ua
- Ukrainian online shops and service providers that sell to local customers.
- IT companies, web studios and digital agencies that work with Ukrainian clients.
- Media projects, blogs and information portals written in Ukrainian.
- Small firms that want a national address in a short form.
Strengths
- The zone signals a Ukrainian business at once, and it is easy to spell and to say aloud.
- It sits inside the national domain, which gives the name a clear local identity.
- For companies that work mainly in Ukraine, the ending helps to build trust and supports local search, provided the site also offers relevant content.
Points to consider
- Visitors who expect a .com address may type it by habit, so protect the brand in other zones if it matters to you.
- Foreign readers may not recognise the ending as quickly as a generic one.
- A name that is very narrow in meaning may limit growth if the business expands.
- Rules for the zone can change, so check them when you order and again when you renew.
Before you register
- Compare the name in .com.ua and .ua, since a name free in one zone can be taken in another.
- Prepare the holder data in advance, exactly as it appears in your official papers.
- Write the main content in Ukrainian and keep the contact details the same everywhere.
- Choose hosting that gives fast access for Ukrainian visitors.
- Enable auto-renewal and add a reminder for the expiry date.
Frequently asked questions
Is .co.ua the same as .com.ua? No. They are separate second-level zones with their own registrations, so a name free in one may be taken in the other.
Does .co.ua help search results in Ukraine? It is a helpful local signal. Relevant Ukrainian content and reliable service still matter more.
Can a company outside Ukraine use .co.ua? Check the registry rules and the conditions for holders before you order, because they can differ from one zone to another.
