# X12ElementLengthValidationRule
<a name="API_X12ElementLengthValidationRule"></a>

This rule allows you to override the standard minimum and maximum length requirements for an element, enabling validation of trading partner-specific length requirements that may differ from the X12 specification. Both minimum and maximum length values must be specified.
