Fraud Alert If you receive a call or text that appears to be from Mastercard or other credit card companies asking you to confirm a recent purchase, it could be a scam! While Sandia Area does send confirmation texts about suspicious purchases, we will NEVER contact you to ask for login credentials for Online Banking or ask you to provide private passwords or other sensitive account information, including accounts numbers and PINs. When in doubt, don't respond. Call us at (505) 292-6343 to confirm any purchases or for additional assistance.
