The DVLA is looking to cash in on motorists by selling their names and addresses to wheel clampers and private parking companies at a profit.
The agency wants to plug a £100m gap in its finances by charging more than the current £2.50 administrative fee.
Last year the agency sold details of 1m motorists to more than 150 parking enforcement companies, angering driving groups.
However, according to Simon Tse, the DVLA’s chief executive, the current fee only covers administrative costs.
Appearing before the Transport Select Committee at Westminster, Mr Tse said the DVLA was in discussions with the Department for Transport about raising the fee.
He added that any change would have to be a "policy decision, a ministerial decision".
With the Government moving to outlaw clamping on private land, a number of companies have moved into ticketing as an alternative.
But their activities have provided hugely controversial. The most expensive private parking ticket costs £150 – £30 more than the maximum fine for illegal parking in the heart of London.
Even the £150 figure, which was set down in the British Parking Association’s code of practice, is only voluntary.
While a motorist receiving a council parking ticket has a right of appeal to an independent adjudicator, no such safeguards exists for anyone “fined” for parking on private land.
Motorists have received private tickets – known as parking charge notices – for spending more than 20 minutes at a fast food outlet or even catching a few hours sleep for safety reasons at a motorway service station.
Private tickets are often enforced by debt collection agencies and occasionally even bailiffs have been involved.
Graham Stringer, Labour MP for Blackley and Broughton, said: "Some of these parking companies are pretty close to the edge of legality. Some are pretty dodgy characters."
Paul Watters, an AA spokesman, said: “Any policy decision ramping up charges for information involved with road safety or for general enquiries from the public would be the wrong one.
“Hiking up the charge for parking companies could backfire on the public too as these unregulated firms will simply increase their penalties to suit – as if they are not high enough already, being three times that for a local authority parking offence.”
Professor Stephen Glaister, director of the RAC Foundation, added: “Rightly, an admin charge is currently levied to cover costs. Wrongly, it seems talks have already taken place about turning the system into a money making scheme.
“Not only would the DVLA be making cash out of drivers’ details, to add insult to injury car owners would ultimately foot the bill, because you can be sure parking companies would pass on the extra charges.”
A spokesman for the British Parking Association said: "Ideally we would like a differential in cost between manual and electronic applications for keeper data, with electronic applications available at a smaller charge.
“We have encouraged our members to access the DVLA database electronically in order to keep their, and the DVLA's, costs down, thereby reducing the cost for the motorist."
A spokesman for the Department for Transport said: "DVLA fees are charged on a cost recovery basis. No decisions have been taken to change that."
