The Whatcom Educational Credit Union has been informing its members that it was experiencing a high volume of counterfeit transactions from stolen debit and credit card numbers and it is blocking transactions in some states outside Washington.
WECU is telling members that if they are experiencing problems with their card being blocked while traveling out of state, they can call toll free at 800-525-8703.
The problem appears to be that a merchant's system was compromised, but WECU was waiting for confirmation on that, said Kessa Volland, marketing manager at WECU.
Volland said the states they are card blocking changes as they learn about fraudulent charges. In-state transactions and online orders where the users enter a personal identification number have not been affected.
