How digital ownership transfer works: DGT, management, and API
11 Jul 2025
In the sale of used cars, one of the most important steps is the transfer of ownership. But did you know that you no longer need to wait in line at the Traffic department? Thanks to digitization, you can manage everything online today. In this article, we explain how the digital process works: what options you have, what you need, and what advantages it offers for a professional dealer.
What is the digital transfer of ownership?
The digital transfer of ownership is the online version of the procedure by which a vehicle changes its owner. The General Directorate of Traffic (DGT) allows it to be done without the need to appear in person, as long as you have the appropriate means: electronic signature, tax payment, and in many cases, support from an agency or digital provider.
3 ways to manage the digital transfer of ownership
1. Through the DGT portal
Requirements:
Digital certificate or Cl@ve.
Proof of payment for the tax on transfers (model 620/621).
Sale contract.
Payment of the fee (55.70 €).
Advantages:
Cost-effective (you only pay the fee).
Disadvantages:
Not agile for professionals.
It can take a lot of time if you are handling many transactions per month.
2. Through a traditional agency
Advantages:
They take care of everything.
Ideal if you don't have a digital certificate or time.
Disadvantages:
Additional cost (from 80 € to 150 € per procedure).
They are not always automated or digitized.
3. Through a platform with an API connected to the DGT (like Dealcar)
Advantages:
All digital and in a few clicks.
Direct integration with DGT and agencies.
Ideal for dealers who make many transactions.
Disadvantages:
You need to register and upload documentation only once.
Documentation required for the digital procedure
Document | Who provides it |
|---|---|
Sale contract | Buyer and seller |
Proof of ITP (model 620) | Buyer |
ID/NIE of the buyer | Buyer |
Vehicle registration certificate | Seller |
Technical sheet (ITV) | Seller |
In transactions between dealers or companies, the type of required fiscal document may vary.
Advantages of automating the transfer of ownership
Time savings: You avoid travel and queues.
Fewer errors: The system validates the data before submission.
Real-time tracking: You can know the status of each transaction.
Scalability: Ideal if you sell 5 or more cars per month.
Conclusion: professionalize your document management
