The Texas robotaxi book is public

TxMCCS prints the operators search as a type, then at least four characters of the operator's information, then a result list. Searches that throw more than 100 entries get cut back to the most recent. Tesla Robotaxi LLC is the name Teslarati used for the 31 August rows. That name is what the book answers to. A vehicle identification number off a social post is not the search.

What you are looking at, if the row comes back, is an authorization holder and the vehicles that holder has attached to that authorization. TxDMV's program page at txdmv.gov/AVprogram says that once an application is complete and approved, the applicant maintains the listing of active vehicles by adding and deleting specific vehicles connected to the authorization. A row on 31 August means the operator put that vehicle on the active list. It does not mean a passenger paid a fare in it that morning. It does not mean the car is unsupervised on your street at the hour you searched.

Senate Bill 2807, 89th Texas Legislature, created the commercial authorization. The department's explainer: companies must receive authorization before operating vehicles controlled by automated driving systems in Texas. The law is in Texas Transportation Code, Subchapter J, Chapter 545. SB 2807 became effective 1 September 2025 so agencies could implement. Administrative rules' latest batch became effective 27 February 2026. Authorization requirements became enforceable 90 days later: 28 May 2026. From that date, companies operating automated vehicles commercially must keep an active TxDMV authorization. That 28 May date is the peg. The bill is older. The teeth started in May.

Commercial activity, in the department's definition, is operation of an automated motor vehicle to transport property or passengers in furtherance of a commercial enterprise on Texas roads without a human driver. Individually owned vehicles, operated for personal use, do not require an authorization. Automated vehicle, here, means a motor vehicle with an automated driving system capable of SAE Level 4 or Level 5 as specified in SAE J3016, April 2021. Tesla already completed that process for the Model Y Robotaxi service Teslarati says has carried paying passengers in Austin, Dallas and Houston. The Cybercab rows join that same legal bucket. They do not, by themselves, open the app.

The application is an attestation, not a road test published in the lookup. The operator attests to traffic-law compliance, a recording device, a lawful automated driving system, a minimal-risk fail state, Texas title and registration, and liability cover at or above the required amount, plus a DPS copy of the emergency-services plan. No fees. Authorizations do not expire. They stay valid until revoked. Material changes must be updated within 30 days.

31 August 2026 is the Cybercab day in that file. Teslarati reported seven purpose-built 2026 Cybercabs under Tesla Robotaxi, LLC, VINs beginning 5YJA, distinct from the 7SAYG Model Y robotaxis. TeslaNorth, 1 September, said the public lookup first showed seven, then 45 by 11:55 a.m. Pacific the same day. EVwire filed 45 Cybercabs joining 269 Model Ys. The FSD Database tracker at fsddb.com printed 269 on 30 August and 314 on 31 August, holding 314 through 2 September. 269 plus 45 is 314. Full vehicle identification numbers are in those trackers. I'm not reprinting them.

A VIN prefix is a family mark, not a spare key. 5YJA is how reporters told a Cybercab row from a Model Y row. 7SAYG is the Model Y mark already on the fleet. Those four or five characters are a reading aid on a list the operator already published through TxDMV. I'm not constructing a number, and I'm not reprinting full vehicle identification numbers from a hobbyist spreadsheet. The lookup answers whether an operator is authorized and whether a listed vehicle sits on that operator's active roster. It is not a kit, and it is not a fare.

Tesla has not, in the reporting I used, said how many of those newly listed Cybercabs will carry guests at the company's 3 September Austin event, or when they enter the Robotaxi app for regular riders. Registration is the prerequisite, not the fare window. Thursday's Austin event is still the launch date Tesla put on the calendar. Two-seat, steering-wheel-free, pedal-free: that is how TechTimes and Teslarati described the Cybercab against the Model Y. Hardware on a list. Not a receipt.

If you want the law more than the rumour, it lives on txdmv.gov/AVprogram. TxDMV issues and can revoke authorizations. The Texas Department of Public Safety and local law enforcement handle on-road traffic. From 28 May 2026, serious public-safety concerns can be submitted for Enforcement review. Roadside, an automated vehicle is subject to the same traffic laws as any other vehicle.

The public tool is still there. An operator name, at least four characters, a row that comes back. Full VINs stay in the state's table. The civic file is for reading whether the operator is on the book.

A fleet is a count, not a slogan. 269 Model Ys on 30 August. 45 Cybercabs added 31 August. 314 authorized vehicles on the tracker through 2 September. SAE Level 4 is the attested capability. 28 May 2026 is the enforcement date. Those numbers are the file.

The public book is txmccs.txdmv.gov/automated-vehicles. Tesla Robotaxi LLC is on it, and so is any other authorized operator the department lists. No account. A listing is a commercial authorization, not a paid fare. SB 2807, enforceable from 28 May 2026, is why that roster has teeth. 5YJA is the new prefix. 7SAYG is the old one. Full VINs stay in the state's table. That's the file.
