What a registered office is for
Every Irish company has a registered office for formal notices and statutory correspondence. The CRO says that the registered office can be checked on CORE and that companies must keep the details up to date and collect post regularly. This makes the address an important identity and contact signal.
The registered office is not necessarily the company’s shop, factory, warehouse or customer-facing office. Companies may use professional office services, shared premises or an address that handles statutory mail while operations take place elsewhere. The correct interpretation is 'official registered address', not 'proof of physical trading'.
How Form B2 fits the address history
A change of registered office is notified to the CRO on Form B2. Current CRO guidance says the notification should be delivered within 14 days of the change. A B2 event therefore helps place an address in the company’s timeline and can explain why old documents show a different registered office.
A recent B2 is not automatically suspicious. It may follow a move, a change of company secretary, a new service provider or a reorganisation. The useful control is to compare the effective date with the documents and explanations relevant to your transaction.
How to use the address in supplier and customer checks
Ask the counterparty which address belongs on the contract and invoice, and why. The registered office, trading address and delivery address can legitimately differ, but the relationship should be clear. A supplier who cannot explain where notices should be served or who will receive payment creates avoidable risk.
Compare the address with the website legal notice, email signature, insurance document, quotation and bank beneficiary. Address mismatches are prompts for verification, not automatic evidence of fraud. The greater the value or urgency, the more important it is to confirm through a trusted channel before payment.
- Registered office for statutory notices
- Trading or operating address
- Delivery, collection or project address
- Invoice and contract address
- Address connected to payment and support
Address history can reveal useful context
A company that has moved several times may be growing, using serviced offices or undergoing a change in operations. A new address alongside director changes, a name change or new financing deserves closer reading because the events may be connected. A long-standing address does not prove solvency or good performance, but it can add continuity to the record.
If the company is newly incorporated, the address provides less history to work with. Ask for references, insurance, contractual details and the identity of the actual operating party. For a property, construction or service transaction, confirm the address that matters to performance rather than relying on the registered office alone.
Preserve the address check
Record the exact address, company number, status and date checked. Where a report is important to the decision, preserve it with the contract and any written explanation of differing addresses. This makes later review easier if the company moves or a dispute arises.
