Back  RFI # 1731: N4 - Foreign Zip Code Requirem

Formal vs. Informal Help Informal Formal


Nancy Reed


We have a descrepancy regarding the N4 zip code element between two validation tools.

One of the validation tools rejects Canadian zip codes that are formatted according to Canadian zip code format requirements (i.e. with a space in the forth position) the other validation tool does not recognize this as an error.

Example: XXX XXX

Our understanding is that the space should not be acceptable based on X12 syntactics - similar to the "dash" in the US postal zip + 4. Please provide direction on the validity of the CA format within an X12 837 claim transaction.
