AC/PRE/ZIP stands for Area Code / Prefix / Zip Code. IDENTITY CHEK looks at a table of zip codes and the area code / prefix combinations ('prefix' is the first three digits of the seven-digit phone number) assigned to that zip code. With all the changes in area codes occurring, sometimes a legitimate phone number won't show up on the table. This typically occurs either when a new subdivision is created, when a change occurs in zoning or when a new area code is implemented.
 
The good news is, there are two ways to change the tables. If the IDENTITY CHEK system sees an AC/PRE/ZIP combination not on the table ten times, after the tenth time it will automatically be added to a special file for your credit union as a valid combination, and will no longer give you that warning. The second way to change the table is to send an email to clientsupport@primarypayments.com with the inquiry number involved in the warning, and any supporting information showing why you feel it is a valid exception to the table. Client Support will add that combination to the table as part of the next monthly update.
