When moving to a new state in Mexico, you’re not automatically required to change your license plates. Some states – like Guanajuato – allow you to keep your existing plates as long as you continue paying the annual vehicle tax. There’s no expiration as long as payments are up to date.
However, not all states make it that easy.
Others require annual re-plating or issuing a new circulation card, which may involve returning in person to your previous state to complete the process.
If you choose to officially register your vehicle in your new state, it’s critical to cancel your previous registration first. Each state operates independently, and if your plates remain active in your former state, taxes will continue to accrue. Some foreigners have been hit with back taxes of 10,000–15,000 pesos because they didn’t cancel plates properly before registering elsewhere.
To cancel plates, you'll need to do what's called an “administrative cancellation” in your old state. If you can't go in person, you can authorize someone to act on your behalf using a notarized carta poder (power of attorney), along with your ID, their ID, and two witness signatures.
If you’re re-registering, bring:
Your original invoice (factura) or title
Proof of payment for taxes and tenencia
Circulation card and cancellation certificate (if applicable)
Residency card or license
Proof of address in your new state
Customs documents (pedimento) if the car was imported
Driving between states with mismatched paperwork? You’ll need a temporary permit to legally transport the vehicle – these now last one to three days and must be issued by your local transit office.
While there’s no official deadline for updating your registration, it's best to handle it promptly to avoid tax penalties and headaches down the road. Check with your state for specific regulations.
