Search the CRO register for your proposed company name and meaningful variations. A clear search is a useful first step, but the CRO decides whether a name is acceptable.
Start with a shortlist
A good name should work in conversation, on an invoice and in a web address. Write down three options before you search. Say each one aloud and ask someone else to spell it back to you. This simple exercise often reveals a problem before you invest in a logo.
Keep a distinctive word at the centre of the name. A descriptive phrase can explain your business, but a name made entirely of common terms can be harder for customers to remember.
Search exact names and variations
Use CORE, the CRO’s official register search, to investigate your shortlist. Search the main words as well as the full name. Try spacing and spelling variations that a customer might naturally use.
Namecheck.ie will bring an initial register check into one place when the businesses.ie connection is live. Until then, our sample result is an illustration and the official register remains the place to check.
Look at similarity, not just spelling
The CRO’s naming guidelines cover similar and phonetically similar names. Adding a general word, punctuation or a place name may not create sufficient distinction. A different spelling can still sound like an existing name.
If a search reveals a close name, return to your shortlist. Choosing a clearer alternative now can save you from rebuilding your identity later.
Check the wider brand
Search for the name on the web and on the channels your customers use. Check the matching domain separately. Investigate trade marks through the Intellectual Property Office of Ireland. These checks answer different questions; one result does not substitute for the others.
Take the next step
Once you have a promising name, compare formation services and their included costs. Treat your search as preparation for an application, rather than approval. Keep a second choice ready, and make final branding commitments after the registration decision.
Work through a fictional shortlist
Imagine a founder choosing a name for a design studio. The shortlist contains “Northstar Studio”, “Northstar Studios” and “Alderline Design”. These examples are fictional and have not been checked for actual availability. The founder writes the exact wording in one column and the distinctive part in another. They search those distinctive words as well as the complete proposed names.
If the first two searches reveal a closely related record, the founder does not treat the extra “s” as a solution. They record the concern, research a genuinely different option and ask their presenter to review the final shortlist. This makes the decision visible instead of burying it in a list of search screenshots.
Record what each check answers
| Check | Record | Decision it supports |
|---|---|---|
| Company register | Search date, wording and relevant records | Whether to investigate a possible company-name conflict |
| Business name | Trading-name research and intended legal owner | Which registration route to discuss |
| Trade marks | Relevant names, goods/services and unresolved questions | Whether professional rights advice is needed |
| Domain | Exact extension, availability check and renewal quote | Which web address to consider buying |
Keep this worksheet privately. It is preparation for your own decision, not a document to upload to Namecheck.ie. A result from one row should never be copied into another as evidence that all checks have passed.
Interpret an unfinished search correctly
A timeout, missing timestamp or incomplete list does not establish that a name is clear. If the tool cannot complete the check, use CORE or return when the service is available. Our sample outcomes show the interface with fictional data; they do not search the register.
Before placing an order, read the similar-name guide and naming restrictions. Then compare the three formation packages against the support you need. Keep a backup name and avoid final branding expenditure while a material question remains unresolved.
