Provider-specific findings

Payment research for this provider

The compiled notes distinguish confirmed channels from details the public material did not expose. Fields containing only an unavailable-information marker are grouped in the research record below.

Payment platform
MyGSWater customer account portal for recurring/self-service account management; one-time guest payments are offered through KUBRA EZ-PAY at the authorized Golden State Water payment link.
Phone payment number
1-844-706-7690, Golden State Water’s 24/7 automated payment service. Customers should have the Golden State Water account number and telephone number available. The company’s general 24/7 customer-service number is 1-800-999-4033, with local San Dimas-area number 909-394-2272.
Pay-by-text
Golden State Water uses MyGSWater account alerts and publishes reminders by mail, email, text, and out-dial calls for past-due or scheduled-disconnection notices. The reviewed payment pages do not publish a separate text-to-pay keyword, short code, or SMS authorization that independently processes a payment. Customers should register contact information in MyGSWater and use the authorized portal or KUBRA EZ-PAY link rather than responding to an unsolicited text.
Mail-in payment address
Golden State Water Company, PO Box 51133, Los Angeles, CA 90051-1133. Checks should be payable to Golden State Water Company and mailed several days before the due date. The company’s customer-service/corporate address is 630 E. Foothill Blvd., San Dimas, CA 91773, but the payment page directs mailed bill payments to the Los Angeles lockbox.
In-person payment
Golden State Water does not present a staffed San Dimas walk-in cashier on its current payment page. In-person cash payment is available through participating KUBRA EZ-PAY retail agents: use the authorized KUBRA locator, select cash payment, generate an EZ-Payslip, and bring it with the cash to the participating retailer. A small retailer service fee applies and payments after 5:00 p.m. post the next business day. General Golden State customer service is available 24 hours a day, 7 days a week by phone; the reviewed materials do not publish a separate San Dimas counter address or counter hours.
Digital payment methods
MyGSWater supports online account management and scheduled electronic payments. KUBRA EZ-PAY supports checking account/electronic check, debit or credit card, and cash at participating retailers; the company’s tariff identifies ATM, Visa, Mastercard, Discover, or electronic check for the telephone payment channel. Golden State also offers no-utility-charge automatic electronic funds transfer from a checking or savings account. Apple Pay and Google Pay are not identified in the reviewed 2026 tariff/payment materials.
Online convenience fees
The CPUC tariff’s Rule 9 identifies a non-refundable $1.45 convenience fee for credit/debit-card transactions up to $800, charged by the payment vendor rather than Golden State Water; one transaction is permitted per assessed fee and each account requires a separate transaction. The current payment page also says a small service fee applies to cash payments through KUBRA EZ-PAY. AutoPay by utility electronic funds transfer has no utility charge, although a customer’s financial institution may charge its own fee and rejected payments can incur additional charges.
