TxMCCS Login: How to Create Your New Account and Claim Your TxDMV Certificate
Reviewed by Austin Park, founder of ICR Filings · Updated November 11, 2026
- TxMCCS replaced both MCCS and eLINC on August 3, 2026. TxDMV says all users must create a new account.
- Sign up at txmccs.txdmv.gov, then claim your existing certificate with your USDOT number and EIN.
- Your certificate was moved to the new system. You are connecting to it, not applying again.
- If the certificate will not connect, TxDMV's help desk is MCD_MCCS-helpdesk@TxDMV.gov or (800) 299-1700, options 3-3.
If you went to print a cab card or renew your Texas certificate and your login was refused, nothing is wrong with your account. The whole system changed. On August 3, 2026, TxDMV replaced its Motor Carrier Credentialing System (MCCS) and eLINC with one new system, TxMCCS, and every user has to start with a new account.
What changed
TxDMV describes TxMCCS as a modernized online system for motor carrier credentialing and account management. It works on computers, tablets, and smartphones, and it adds self-service features the old systems did not have: online document uploads, password resets, account requests, alerts and notifications, and immediate cab card printing. Carriers, insurance companies, and licensing agents all use it, each with their own kind of account.
Step 1: create your new account
Go to txmccs.txdmv.gov and select Sign Up on the landing page. TxDMV says all users must create a new account, including carriers who had an MCCS or eLINC login for years. Use an email address you check: TxDMV sends insurance filing notices and renewal notices to the address on your account.
“All users must create a new account in TxMCCS.”

Step 2: claim your existing certificate
If your company had a certificate in MCCS, TxDMV transferred it to TxMCCS. Once you sign up you land in the TxMCCS Application Portal, and TxDMV's instructions are:
- Select the top tile to claim your existing motor carrier certificate.
- Select Accept at the bottom of the next screen.
- Choose Motor Carrier and select Next.
- Enter your USDOT number and Employer Identification Number (EIN), then select Continue.
- Review and confirm your company information and select Claim Certificate.
- Select Go to Company Details. Your motor carrier certificate should be displayed.
TxDMV's instructions ask for an EIN and do not say what a carrier registered without one should enter. If that is you, ask the help desk before guessing.
If you are new and never had a certificate
The same site is where first-time applicants start. You sign up, apply for Texas operating authority, and TxDMV reviews the application within 24 to 48 business hours. You need a valid USDOT number before you begin. The steps and fees are in how much a Texas DOT number costs, and TxDMV number vs USDOT number explains which one you need.
If it will not connect
TxDMV's contact for problems connecting an existing certificate to a new account is MCD_MCCS-helpdesk@TxDMV.gov. For questions about TxMCCS by phone, it lists (800) 299-1700, options 3-3. TxDMV also publishes tutorial videos on its Motor Carrier Outreach and Training page.
Once you are in
- Print your insurance cab card and put a current copy in each truck.
- Renew your certificate before it expires.
- Add or replace a truck when your fleet changes.
- Check that your insurance filing shows as active. TxDMV holds the carrier responsible for keeping it filed.
Common questions

TxDMV replaced both systems with TxMCCS on August 3, 2026, and says all users must create a new account. Old usernames and passwords were not carried over.
Where do I log in to TxMCCS?

What can I do in TxMCCS once I am in?
TxDMV lists obtaining Texas operating authority, updating carrier information, renewing a certificate, and printing cab cards.
