CORE (Companies Online Registration Environment) is the online filing facility of Companies Registration Office. It has been developed to allow you, as a CRO customer, to view in a secure, private environment, up to date information on companies for which you file.
CORE will enable you to :-
* File documents online (some documents can be filed for free)
* Check the status of your companies in lists which can be sorted in various orders
* Receive notification of filings for companies in your portfolio and of changes in the status of those documents
* Watch your companies
* Obtain your CRO Account balance, transactions and statements

To avail of CORE you need to be a registered user. Registration is free.
When you register, you will use your email address as a username and then choose a password. You will only need to register once and after that you can file forms for as many companies as you wish.
If you are an accountancy practice or a filing agent, register in CORE in the name of your own practice, using your own business name or company number. You do not need a seperate log in for each company for which you want to file.

In order to file online you will need to have the following:
- A valid email address
- Adobe Acrobat 8 or greater on your computer
- Adobe acrobat is a free download from www.adobe.com. You will need to download this onto your computer before filing electronically.
- A printer
Make sure that your printer is connected to your computer as you need to print out a signature page at the end of filing your form
Each time you create a new document, a copy of that document is held in a special folder known as Workspace. In the Workspace you will see a heading "Submitted". Under this heading you will see some icons.
If you have completed and successfully sent your form you will see three icons.
(1) The first icon is a copy, for your own records, of the form you have submitted.
(2) The second icon is your signature page. If for any reason your signature page did not print, click on this icon to open it again.
(3) Click on the third icon to open your form as a copy.
NB: We have made some changes recently to make CORE more efficient, one of these changes is to limit the number of drafts in a user's workspace to the last 100 days. However, nothing is deleted or lost. If a user wants to recover a submission before that date then they just need to enter the company number or submission number in the search bar just above the workspace drafts. This will recover anything beyond the most recent 100 days."
- Log back in using your username (email address) and your password
- Click on Workspace
- On the right of your Workspace under the heading 'Submitted', you will see three icons
- Click on the icon "Open as copy"
-Make the required changes and submit the document again
You will receive a new signature page which should be printed, signed and posted to this Office.
If you have forgotten your password
- Go to the login screen
INSERT the text - "Click on the option " forgotten password" "
- Fill in your username (email address) and your surname and forename
Your password will be emailed to you.
A company name can be reserved prior to incorporation using the CORE facility. Select File a Form and choose Reservation of Company Name. The name will be checked for suitability and then can be reserved for 28 days. See Reserve a Company Name page for more information.
Make sure you have Adobe Acrobat Version 8 or later on your PC. If you don't have Adobe Acrobat you will need to download it before proceeding. You can download Adobe Acrobat free of charge at www.adobe.com
Once you have installed Adobe Acrobat, log back into our online filing system.
- Go to your Workspace
- In the "Submitted" panel and towards the right hand side of the page, click on the icon "Open Signature Page"
- Print this page If you click on the "Open Signature Page" and you get an error, (e.g. Error 500) this means you do not have the correct version of Adobe Acrobat on your PC or it is not installed correctly.
