<h1>Part V: Decline and Error Responses</h1>
<p>
This document describes the content of an ECHOTYPE1 response containing a
decline or error response received from the <font face="Verdana,Arial,Helvetica" size="-1">
<b><i>ECHO</i></b></font> host computers. For a general description of <b><i><font face="Verdana,Arial,Helvetica" size="-1">
ECHO<font size="-2">NLINE</font></font></i></b> responses see <a href="ISPGuide-Interface.asp#Responses">
Response Protocol</a>
in Part I of this Specification.
<p>
Host responses differ depending on the transaction code and whether or not an
error or decline was detected by the host. For a description of acknowledgement
and approval responses see <a href="ISPGuide-Response.asp"><b>Part IV: <i><font face="Verdana,Arial,Helvetica" size="-1">
ECHO<font size="-2">NLINE</font></font></i> Host Responses</b></a>
.
<p>
Credit card transactions and electronic check transactions differ slightly in
their format. For this reason they are treated separately in the sections
below. In the examples, the "·" character is used to indicate a space
character.
<h2>Credit Card Transactions</h2>
Decline and error responses are very similar in that they both represent
situations that prevent a transaction from being authorized. Decline codes can
actually represent a system error, and error codes can actually represent an
account restriction. The difference between the two is more of a historical
artifact than any distinction between an "error" and a "decline."
<p>
Decline responses are always preceded by the word "DECLINED," while error
responses contain various text messages from <b><i><font face="Verdana,Arial,Helvetica" size="-1">
ECHO</font></i></b>'s host computer or the issuer's computers.
Decline and error responses are described below.
<h3>Message Formats</h3>
<p>
Decline responses are formatted as follows.
