Mail, text, and in-person payment instructions
Pay by text
A dedicated this detail was not publicly posted. The current DallasGo and DWU payment pages publish online Guest Pay, profile/AutoPay, automated phone, mail, authorized pay stations, City Hall cashier windows, and a drop box, but no official text-to-pay short code, keyword, or opt-in process.
Mail-in address
Current upgraded-platform instructions: City of Dallas, P.O. Box 660025, Dallas, TX 75266-0025. Customers should enclose the bottom portion of the paper bill, use a check or money order, and never mail cash. A legacy City payment page lists P.O. Box 075277, Dallas, TX 75277-1000, so the remittance address printed on the customer’s current statement should control during the 2026 billing-system transition.
Counters, drop boxes, and office hours
Payments are accepted at Dallas City Hall, 1500 Marilla Street, cashier windows on the second-floor lobby at Room 2DS, Monday through Friday from 8:00 a.m. to 5:00 p.m. The same location has a night-deposit box in the driveway between Young Street and Canton Street; only checks or money orders should be placed in the box, never cash. Current bills may also be paid at any authorized DWU pay station; the City directs customers to call 214-651-1441 for the nearest station rather than publishing a stable complete list on the page. City Hall cashier service and authorized stations should be used instead of mailing a payment after a termination notice, because DWU says mailed payments may arrive too late to cancel disconnection.
