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; one-time guest payments are available through Golden State Water’s authorized KUBRA EZ-PAY channel.
Phone payment number
1-844-706-7690, Golden State Water’s 24/7 automated payment service. Have the account number and account telephone number ready. General customer and emergency service is available at 1-800-999-4033 or local 909-394-2272, 24 hours a day, 7 days a week.
Pay-by-text
The company sends past-due and scheduled-disconnection reminders by mail, email, text, and outbound calls when current contact information is maintained in MyGSWater. No separate text-to-pay keyword, short code, or SMS payment authorization procedure is published in the reviewed 2026 materials; customers should use the authorized portal or IVR and avoid paying through an unsolicited text link.
Mail-in payment address
Golden State Water Company, PO Box 51133, Los Angeles, CA 90051-1133. Make checks payable to Golden State Water Company and mail several days before the due date. The company’s San Dimas corporate address, 630 E. Foothill Blvd., San Dimas, CA 91773, is not the lockbox address specified for mailed bill payments.
In-person payment
Golden State Water does not publish a staffed Claremont cashier location on its current payment page. Cash can be paid in person at participating KUBRA EZ-PAY retail agents by using the authorized locator, choosing cash payment, generating an EZ-Payslip, and bringing the slip and cash to the selected retailer. A small KUBRA service fee applies and payments after 5:00 p.m. post the next business day. Customer-service and emergency representatives are available by phone 24/7; no separate Claremont walk-in counter hours were located.
Digital payment methods
MyGSWater provides self-service billing, payment history, paperless billing, and scheduled online payments. KUBRA EZ-PAY supports checking/electronic check, debit or credit card, and cash at participating retailers; Golden State’s tariff identifies ATM, Visa, Mastercard, Discover, or electronic check for telephone payments. Utility electronic-funds-transfer AutoPay draws the total bill from checking or savings on the due date without a utility enrollment charge. Apple Pay and Google Pay are not identified in the reviewed materials.
Online convenience fees
Golden State Water’s CPUC 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 the utility; each account transaction is assessed separately. KUBRA cash payments carry a small service fee. Bank AutoPay has no utility charge, although a bank may charge its own fee and rejected payments may incur additional fees.
