An Irish company’s incorporation date is the date the company was registered as a legal entity. You can check it by searching the legal name or CRO registration number and verifying the registration date on the company record. The date proves legal age—not when the business began trading, launched a brand, hired staff or came under its current owners.
Fastest reliable method
Find the exact company, record its CRO number and registration date, then inspect the certificate of incorporation or source CRO documents when formal evidence is required. Always compare the date with filing history and the business claim you are checking.
How to find an Irish company’s incorporation date
- Get the legal company name. A shop, app or employer may use a different trading name.
- Search by name or CRO number. The CRO number reduces the risk of selecting a similarly named entity.
- Check the registration date. Businesses.ie company profiles present the incorporation date available in the public company data.
- Confirm the status and company type. Age has different relevance if the company is dissolved, strike-off listed or recently restored.
- Obtain source evidence if necessary. A certificate of incorporation is the formal evidence commonly requested for onboarding or transactions.
What the incorporation date means
The date marks the creation of the company as an incorporated legal person under the relevant company law. It is used to understand legal age, sequence filings, calculate when early compliance events should occur and distinguish the company from businesses with similar names.
The CRO’s public data includes a registration date where applicable. For an existing company, the certificate of incorporation records the name and date on which the entity was incorporated. Later certificates may record a name change, but a change of name does not normally restart the company’s legal age.
What the incorporation date does not prove
| Claim | Does incorporation date prove it? | Better evidence |
|---|---|---|
| “Trading since 1998” | No | Contracts, tax/trading records, accounts and predecessor history |
| “30 years of industry experience” | No | People, predecessor businesses and verifiable project history |
| Currently trading | No | Current operational evidence and independent verification |
| Financially stable | No | Current financial and credit evidence plus filed accounts |
| Same ownership since formation | No | Shareholder and control history |
| Brand existed from that date | No | Business-name, trade-mark, domain and marketing records |
Company age vs business age
A business can be older than its company. A sole trader or partnership may operate for years before transferring activity to a newly incorporated company. Conversely, an old dormant or shelf company can be acquired and start a new trade much later. The age claim should specify whether it refers to the legal company, brand, underlying business, team experience or group.
If the distinction matters, ask for a timeline showing predecessor entities, asset transfers, business-name registrations and ownership changes. Do not assume the new company inherited every contract, liability, licence, insurance record or reputation of the previous business.
How old is the company today?
Company age is the elapsed time between the incorporation date and the date of your review. Report both dates rather than only saying “12 years old,” because age changes and databases can be read later. For example: “Incorporated 14 March 2014; approximately 12 years old as at 20 August 2026.”
A dissolved period or restoration can complicate the practical history. A restoration may place the company back on the register under the applicable legal effect, but it does not mean the company traded continuously throughout. Review the status timeline and obtain legal advice if continuity matters.
Why incorporation date matters in due diligence
- Supplier checks: compare claimed track record with legal age and filed history.
- Credit: a very new company has a limited public filing history, so request more current evidence.
- Employment: verify that an employer’s history claim matches the contracting company.
- Investment: reconcile incorporation, founder, share and trading milestones.
- Tenders: distinguish company age from predecessor or staff experience.
- Fraud controls: investigate a recently incorporated entity impersonating an established brand.
New company does not automatically mean high risk
A legitimate company can be newly formed for a project, investment, property, acquisition or group reorganisation. The lack of history simply changes the evidence available. Check founder and director experience, funding, contracts, licences, insurance, references and the reason for the structure. Scale the payment terms, deposit and monitoring to the exposure.
Likewise, an old company is not automatically safe. It may be dormant, inactive, recently acquired, late with filings or operating a completely new activity. Age is context, not a credit score.
Certificate of incorporation vs company profile
A profile is useful for rapid research and ongoing context. A certificate is a source document commonly used as formal evidence that the company was incorporated. Depending on the transaction, you may also need a certified document, current company status evidence, constitution or recent filings.

Company-age verification checklist
- exact legal name and CRO number;
- registration/incorporation date;
- current status and company type;
- previous names and name-change dates;
- first and latest filing dates;
- any strike-off, dissolution or restoration period;
- claimed trading-start date and supporting evidence;
- ownership or business-transfer history where relevant;
- formal certificate when required by the decision.
For wider evidence, review the CRO filing history and learn how to assess whether a company is still trading.
