Under the new rule effective 1-1-18, 1003.4(a)(1)(I)(B)the ULI must include up to 23 additional characters to identify the covered loan or application, which:
(1) May be letters, numerals, or a combination of letters and numerals;
(2) Must be unique within the financial institution; and
(3) Must not include any information that could be used to directly identify the applicant or borrower…
If your system consistently adds a character to the end of the original loan number both on your core and for HMDA that should be fine. If the number doesn’t change on your core, but is changed (character added) for HMDA reporting it does not seem to meet the requirement that the number be unique within your financial institution since you are using the same number for the purchase and refi on your core.
We are hosting a HMDA webinar that will cover this on April 10. It is HMDA Implementing the New Rules Part 2 – Completing the Revised LAR and is accessible by clicking here.
