Alternative channels
Mail, text, and in-person payment instructions
Pay by text
The City’s current utility-billing pages document text and email consumption alerts through the customer portal, but do not document a text-to-pay enrollment keyword or bill-payment SMS short code. Customers can register in the portal, set communication preferences, and configure usage-threshold or continuous-use alerts by text; those alerts are not represented as a payment authorization channel.
Mail-in address
Utility Billing, City of Round Rock, 221 E. Main Street, Round Rock, TX 78664. The City directs customers to include the payment stub or account information so the mailed check or money order can be credited to the correct CID/account.
Counters, drop boxes, and office hours
The Utility Billing lobby is on the first floor of City Hall, 221 E. Main Street, Round Rock, Texas 78664, and is open Monday through Friday from 9:00 a.m. to 5:00 p.m., excluding City holidays. The City accepts in-person payment at the lobby and provides self-service cash options through the online portal: a portal-generated cash barcode can be used at participating retailers such as CVS, Walgreens, Dollar General, and Office Depot for a $2.95 retailer transaction fee, while Walmart MoneyCenter accepts cash, debit cards, or Ucards for a $1.50 fee. A 24-hour deposit box along Bagdad Avenue at City Hall accepts checks and money orders only; the City’s current page does not present a separate staffed counter-hours schedule beyond the lobby hours.
