Mail, text, and in-person payment instructions
Pay by text
No NBU text-to-pay keyword or SMS enrollment workflow is published. AutoPay is enrolled through the online account under Pay Your Bill and My Profile; NBU's leak/interval usage notifications are separate from a payment authorization.
Mail-in address
A dedicated this detail was not publicly posted. The reviewed current NBU payment-options page emphasizes online, phone, and AutoPay methods and does not expose a stable 2026 mail-remittance address. Use the address printed on the current NBU bill.
Counters, drop boxes, and office hours
NBU payment-counter locations and current hours were not fully exposed in the reviewed payment page. Customers should use NBU's current customer-service contact page or bill for counter, drive-through, kiosk, and drop-box details; the automated phone system is available 24/7.
