    B021Invalid ZIP Code

    The ZIP Code is malformed or contains non-numeric characters

    Affected Field
    #42ZIP Code

    Description

    The ZIP Code field must contain either a five-digit ZIP or a nine-digit ZIP+4, left-justified with no hyphen. Embedded hyphens, letters, or fewer than five digits cause matching failures and may be rejected.

    Common Causes

    • Hyphen left in a ZIP+4 value
    • Canadian postal codes placed in a US ZIP field
    • Fewer than five digits

    How to Fix

    1. 1Strip hyphens; store 5 or 9 contiguous digits
    2. 2For non-US addresses, set the Country Code appropriately
    3. 3Validate ZIP length before file generation

    Examples

    Invalid
    78701-4321
    Valid
    787014321
    Remove the hyphen; ZIP+4 is nine contiguous digits
