Payment channels

Pay Martin County Utilities and Solid Waste

Use the provider’s verified online, telephone, mail, or counter instructions. Check the final confirmation screen for the amount, processing date, and any transaction fee before submitting.

Primary online route

Use the official payment portal

The direct portal is the fastest route when it is available. The provider identifies its payment gateway as Online-Biller. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

A dedicated this detail was not publicly posted. Martin County publishes (772) 221-1434 for credit-card payments with Customer Service Monday-Friday 8:00 a.m.-5:00 p.m., but the reviewed official page does not identify a separate automated IVR number.

Have your account number and payment instrument ready. Follow the provider’s recorded prompts and retain the confirmation number.

Alternative channels

Mail, text, and in-person payment instructions

Pay by text

A dedicated this detail was not publicly posted. The reviewed Martin County bill-payment page provides online enrollment, automatic bank draft and regular-hours telephone payment, but no verified SMS keyword or text-to-pay enrollment flow.

Mail-in address

Martin County Utilities, P.O. Box 9000, Stuart, FL 34995-9000. Include the payment stub and account number; do not mail cash.

Counters, drop boxes, and office hours

Martin County Utilities, 3473 SE Willoughby Boulevard, Stuart, FL 34994. The official page confirms in-person payment by cash, check or credit card, but does not publish a counter schedule beyond Customer Service Monday-Friday 8:00 a.m.-5:00 p.m. The same page documents an automatic bank-draft plan and says new-account same-day service is unavailable after 2:30 p.m. beginning May 11, 2026; it does not list separate drop-box locations.

Accepted digital instruments

What you can use online

Online-Biller account payments and regular-hours credit-card payments are available. Martin County also offers a PreAuthorized Direct Bank Payment Plan that electronically drafts the monthly bill without an additional charge; the reviewed page does not enumerate card brands or mobile wallets.

2026 transaction pricing

Convenience fees

A dedicated this detail was not publicly posted. The official bill-information page explicitly describes recurring bank draft as having no additional charge but does not publish a current online card or e-check convenience-fee schedule.

Fees can vary by payment type, channel, account class, and processor terms. The checkout screen is the final fee disclosure.

Payment guidance

Choose the payment channel that fits your deadline

The safest payment path is the one published by Martin County Utilities and Solid Waste and matched to the account information on your bill. Online portals are convenient, but telephone, mail, counter, and drop-box options may follow different posting schedules and may use different fees.

For a routine payment, save the final confirmation page or IVR number and check when the transaction will post. For a same-day shut-off notice, do not assume that submitting a card payment automatically stops a field order; ask the provider what amount and confirmation are required.

Never send your account number, password, card details, or bank information to Water Ledger. Those details belong only on the provider’s verified payment channel or at an authorized counter.
