Mail, text, and in-person payment instructions
Pay by text
No current City page publishes a text-to-pay keyword, short code, or SMS enrollment sequence. Oceanside publicly promotes WaterSmart registration, email verification, automatic debit/credit/checking payments, and online usage alerts instead. Do not text a payment keyword to an unverified number; confirm any future SMS program with Utility Billing at (760) 435-3900.
Mail-in address
City of Oceanside Utility Billing, 300 North Coast Highway, Oceanside, CA 92054. The current public pages identify the civic mailing address but do not expose a separate 2026 lockbox/remittance PO Box; customers should use the payment stub’s remittance instructions and allow normal mail time.
Counters, drop boxes, and office hours
The Utility Billing customer-service office is at 300-C North Ditmar Street, East Building, City Hall East, Oceanside, CA. Published counter hours are Monday through Thursday 7:30 a.m.–5:00 p.m. and Friday 7:30 a.m.–4:00 p.m.; the City lists (760) 435-3900 for utility-billing representatives and (760) 435-4500 for general water-utility contact. Current public pages do not provide a complete list of satellite counters, drop boxes, or a definitive counter-card acceptance matrix, so those details should be confirmed before visiting.
