Ways to Pay at PayMobilityBill.com
You can pay a Mobility Authority toll bill several ways.
- Online:
- Go to PayMobilityBill.com (or via “Pay Online” on mobilityauthority.com).
- Enter your invoice number and license plate (or search by plate if allowed).
- Review charges and pay by credit/debit card, bank account, Apple Pay, or Google Pay.
- By Phone:
- Automated attendant 24/7: 833‑762‑8655 (toll‑free) or 512‑410‑0562 (local).
- By Mail:
- In person:
- Pay at the Mobility Authority Customer Service Center (Austin area; address on invoice/website).
If you have an electronic tag like TxTag, TollTag, EZ TAG, K‑TAG, PikePass, ExpressToll, SunPass, tolls should post to that account at tag rates when your account is funded and your plate matches.
Pay By Mail / Plate and QR Code or SMS
If you do not have a tag, cameras capture your plate and generate a Pay By Mail invoice.
Some invoices also support text-to-pay (e.g., texting a keyword like “RMA” to a short code as printed on the bill), which then returns a secure link to pay.
Important Notes for Austin-Area Drivers
Austin has two different toll authorities and two billing systems:
- Mobility Authority (PayMobilityBill): 183A, 290 Toll, 71 Toll, MoPac Express Lanes, 45SW, 183 Toll.
- TxDOT/TxTag (processed by HCTRA): Loop 1, SH 45 N, SH 45 SE, SH 130.
If you drive both systems without a funded tag, you can receive two separate invoices and must pay each one (PayMobilityBill for Mobility Authority roads and TxTag/HCTRA for TxDOT roads).
Avoiding Fees and Collections
- Pay invoices before the due date to avoid late fees and collection referrals (Penn Credit handles some delinquent accounts).
- Keep your tag account funded; if your TxTag/TollTag/EZ TAG runs out of money, you’ll start getting Pay By Mail invoices at higher rates plus fees.
- Always use PayMobilityBill.com or official Mobility Authority channels—ignore random texts/emails that don’t match the info on your physical invoice.
FAQs About PayMobilityBill.com Toll Payments
1. What info do I need to pay at PayMobilityBill.com?
You typically need your invoice (statement) number and license plate number as listed on your Mobility Authority toll bill.
2. Can I pay a toll before the invoice arrives?
In many cases you can by calling the Mobility Authority or using online lookup options, but generally payment is easiest once you receive the Pay By Mail invoice with your statement number.
3. Why did I get more than one toll bill for Austin?
Because Austin tolls are split between TxDOT (TxTag/HCTRA) and the Mobility Authority; trips on each system generate separate bills if you don’t have a properly funded tag.
4. What if I already have TxTag/TollTag/EZ TAG?
As long as your tag account is funded and your plate is correctly linked, those tags are accepted on Mobility Authority roads and you shouldn’t get a Pay By Mail invoice for those trips.
5. How do I pay if my account was sent to collections?
Follow the instructions on the collection letter (often Penn Credit) or pay through PayMobilityBill.com if it still accepts your invoice number; both options are commonly listed.
6. Who do I contact with questions?
Call 833‑762‑8655 or the local number on your bill, or use the contact options on mobilityauthority.com’s Pay Your Toll page for assistance.
