Payment channels

Pay MUSTANG SUD

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 Mustang SUD’s official website payment portal; the public 2026 pages do not name the underlying processor.. Never enter account credentials into a lookalike site reached through an unsolicited message.

Telephone payment

Phone IVR

844-201-8794 for automated telephone payment.

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

No current Mustang SUD pay-by-text keyword or SMS enrollment sequence was published. Customers can use the website payment path, automatic bank draft, bank bill pay, office counter, mail, or the 24/7 exterior drop box for checks.

Mail-in address

Mustang Special Utility District, 7985 FM 2931, Aubrey, TX 76227. Mail a check using the bill’s account information; payments are processed on the date received, not the postmark date, and the District says postal delay does not excuse late payment.

Counters, drop boxes, and office hours

Mustang SUD headquarters is at 7985 FM 2931, Aubrey, Texas, with business hours 8:00 a.m. to 4:30 p.m. Monday through Friday. A Gunter satellite office is at 108 Pike Road, Gunter, Texas. Customers may pay cash, check, or card at an office and may use the exterior 24/7 drop box for checks only.

Accepted digital instruments

What you can use online

Mustang accepts online credit-card payments, automatic bank draft, and bank bill-pay payments. The current FAQ also lists office card payments; it does not enumerate card brands or digital wallets.

2026 transaction pricing

Convenience fees

No current 2026 online convenience-fee amount is published on Mustang SUD’s public rate/payment pages. Any processor charge shown at the live payment step controls.

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 MUSTANG SUD 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.
