Dear Member,

With Cuchullain Credit Union and Dundalk Credit Union now successfully merged, you will notice that the format of your former Cuchullain Credit Union membership number has changed slightly.

Your new account number will still contain your original Cuchullain Credit Union number at the end, it will just have a 6-digit format, this is achieved by simply adding 100,000 to your number. For example where x is the digits in your Cuchullain account number:

Former Cuchullain Credit Union Account Number New Dundalk Credit Union Account Number
xxx 100xxx
xxxx 10xxxx
xxxxx 1xxxxx
