What is the loan/share type map template and where can I find it?

The mapping template is used to map the credit union’s loan/share type codes to a standard NCUA list of type codes for better analytics and loan review selection. There are separate type map templates for loans and another one for shares. A type map template is required to upload loan and share files through DEXA. The type map templates can be found on the DEXA webpage.

NCUA Letter to Credit Unions 03-CU-05 requires the Loan Term data field to be alphanumeric with no more than 3 characters. However, my credit union has loan terms exceeding 999. Can you please advise?

Although the schema indicates the loan term cannot exceed 3 characters, the NCUA understands that credit unions may have loans with more than 999 contractual payments. The NCUA has updated DEXA and the system will accept a loan term with up to five characters.
