RE: Change to Credit Card Number Truncation Requirements

Beginning January 1, 2009, all receipts involving credit card or debit card 
transactions that are printed at the time of the purchase, exchange, refund, 
or return are prohibited by California Civil Law from displaying anything 
other than the last 5 digits of the card number or the expiration date.

If your department is a merchant that processes credit card and debit card 
transactions on a First Data terminal, please complete the following 
activities before December 31, 2008:

1) Gather the relevant information together; including merchant number, 
terminal id number and terminal serial number (this information is 
available on the sticker affixed to your terminal)
2) all First Data Terminal Support at 800-346-3315
	a. Select option 1 for English language instruction
	b. If prompted, enter your merchant number followed by the ‘#” key 
	c. Select option 2  for “credit card programming” 
	d. Select option 1 for “terminal needs programming”
	e. Wait for technician and request programming download to truncate all 
	   receipts.
	f. Follow programming instructions of the technician
3) After successful programming download, please verify that only the 
last 5 digits of the card number displays on any receipt that prints out of 
the machine at the time of transaction.

If you are a merchant that processes credit card or debit card transactions 
through a Point of Sale system, an internally hosted or an externally hosted 
web site, please ensure through your technical staff and/or vendor that all 
receipts that are printed or available to print at the time of the 
transaction truncate the card number to the last 5 digits.  

If you have questions, please contact Maureen Pigozzo at mdpigozzo@ucdavis.edu  
for assistance.
