How to link an existing registration

Landlords must register their tenancies with the Residential Tenancies Board (RTB). If your current tenancy is not showing on your new registration account when you log in, you can link it manually. The process is different depending on your account type: Individual, Company or Approved Housing Body (AHB).

Individual accounts

Follow the steps below to link a tenancy.

1. Log in to your registration account

  • Select the ‘Linking an Existing Registration’ from the homepage.
  • Make sure your surname and email address match those on the tenancy registration you want to link to.

2. Linking options

There are two ways to link the tenancy:

Option 1: Use the RT number

  • Enter the RT number (unique number assigned to each tenancy registration) in the format RT-XXXX-XXXXXXXX.
  • To enter multiple RT numbers, separate them with a comma and no spaces. For example, RT-XXXX-XXXXXXXX,RT-XXXX-XXXXXXXX.
  • You can enter up to 6 RT numbers.
  • Your surname and email will be auto-filled, greyed out and can’t be edited.

Option 2: Use the Account ID number

  • Enter your five-digit Account ID from your previous registration account.
  • Your surname and email will be auto-filled, greyed out and can’t be edited.

3. Link to registration

  • Click ‘Link to Registration’.
  • Review identified registration records.
  • Select ‘Link’ to add the records to your online account.
  • If the record is marked ‘Unmatched’ you need to provide more information before the record can be linked. Select ‘Unmatched’ to provide details.

4. Review registration

  • You can add parties to the record (if you need to).
  • Select ‘Accept’ to add the registration record to your account.
  • Select ‘Reject’ if you don’t want to add the registration record to your account.

5. Linking is successful

Once linked, registration(s) will appear under ‘Renew Annual Registration and Manage Registrations’ on your homepage.

6. Linking is unsuccessful

If the linking is unsuccessful, it is marked ‘Unmatched’ on your ‘Renew Annual Registration and Manage Registrations’ section.

You need to provide more information so we can identify the correct registration record(s). We will contact you once we have located the record(s).

Company accounts

Follow the steps below to link a tenancy.

1. Log in to your registration account

  • Select the ‘Linking an Existing Registration’ from your company homepage.
  • Only the main company account can link registrations (branches cannot do this directly). The main company account can link existing registrations and then assign them to a branch.
  • The CRO number on your company account profile must match the CRO number on the tenancy registration you want to link to.

2. Linking options

There are two ways to link the tenancy: using the RT number or using your Account ID number. Follow the same steps as in the individual accounts section above.

The CRO number on your account profile will be automatically populated, greyed out, and can’t be edited on the linking page.

3. Finalising the link

Follow the same steps as in the individual accounts section (steps 3 to 6). If the linking is unsuccessful, additional details may be required. We will contact you if needed.

Company accounts linking multiple tenancies (bulk linking)

Landlords and agents with a large volume of existing tenancies can use a data linking spreadsheet.

This allows you to provide all the necessary information to link each tenancy record, without the need to submit multiple requests in your online account.

How to use the spreadsheet

  • Download and save the spreadsheet.
  • Complete the spreadsheet with as much information as possible for each tenancy record so we can identify it correctly on our system and link it to your account.
  • Save it and email the completed spreadsheet to lettingagents@rtb.ie.
Important notes
  • Existing records may have different details, such as the landlord or agent names or company information, which could cause delays. Include these details with the completed spreadsheet in your email to the Data Linking team.
  • The Tenancy Registration Account system does not allow for variations, so provide as much accurate information as possible.
  • We may need to do additional verification to ensure data is linked to the correct account.

Approved Housing Body accounts

Approved Housing Bodies (AHB) accounts are set up by the RTB and your tenancy records are linked automatically to your registration account.

If you have a query about linking a tenancy registration to an AHB online account, contact  AHB@rtb.ie.
