List of CC/ACH errors and possible causes for Troubleshooting?
I was wondering if there was a list of common rejection codes that are seen in the ACH/CC billing responses with a little more information on what they mean.
These codes are easy enough to decipher:
Decline: Insufficient funds
TSYS Error: CARD NO. ERROR
TSYS Error: EXPIRED CARD
R01 : Available balance is not sufficient to cover the debit ent
R04 : Account number structure not valid. May contain incorrect
These codes are more vague to the naked eye, but I was wondering if they maybe had specific root causes?
Decline: Do not honor
Decline: Invalid service code, restricted
TSYS Error: HOLD-CALL
X08 : Unknown Code
Thanks for your help, as always!

The codes are processor specific and I don't have any additional information to add on them. You could call the processor and they might be able to explain them.
Thanks Andy!
