The demand came from the DVLA (Driver and Vehicle Licensing Agency), a British government organisation which sorts out driving licences and sells personalised number plates.
Alan Clarke, 49, bought the plate six weeks earlier from the DVLA website for £399 ($638) to put on his black Range Rover, before he received a letter informing him that it was "causing offence".
The car owner has so far refused to carry out the request to remove it, according to the Mirror. He said: "It's my plate and I'm not taking it off... They are threatening to criminalise me.
"They are a government agency and put the plate on their own website. I saw it there and thought it would be fun to put it on my new car. Everyone laughs when they see it. They sent me a normal plate to put on but I sent it back. They've still got similar plates on the site."
Clarke faces a fine of up to £1,000 ($1,600) if he fails to comply, while the DVLA has insisted that he would be refunded for the number plate.
The DVLA explained: "We try to identify combinations that may cause offence. When potentially offensive plates slip through the net, steps are taken to withdraw the registration number.
"This plate has been withdrawn. Therefore, it is an offence for the driver to still display it. [However], he would receive a refund."
