More than 4,200 people in Hull were caught watching TV without a licence last year.
TV Licensing has revealed more than 500 were also caught in Bridlington, more than 100 in Beverley and more than 50 in Hessle.
The average evasion rate remains at a low of just over five per cent, meaning almost 95 per cent of homes are correctly licensed.
Lucy Baird of TV Licensing said: "The data released today shows evasion remains at historically low levels of approximately five per cent, with the overwhelming majority of people ensuring there are correctly licensed. In order to be fair to the law-abiding majority who do pay for their licence, we'll continue to pursue the small minority of people do not pay."
A colour TV Licence currently costs £145.50 and is required by anyone watching or recording TV programmes as they are shown on TV, whether they are using a TV set, computer, or any other equipment.
