A mounted policeman, formerly based in Harrogate, rode into trouble when his long-running credit and goods scam was discovered, a court was told.
PC Shimon Ben-Avrohom Aaronson - previously called Simon Madden - lied about his past to avoid credit checks and fiddled four-figure sum loans and hired cars.
York magistrates heard how Aaronson, aged 36, obtained services by deception over a two year period while serving with North Yorkshire police in Harrogate and told him a prison sentence was a possibility.
Prosecutor Mr Simon Orme said the first offence took place in February 1994 before he changed his name by deed poll when he became a Jew.
He altered the date of birth on a photocopy of his driving licence so he could obtain credit without alarm bells ringing when companies checked his name on their databases.
Mr Orme added: "It was a cut and paste job which he faxed to his insurers, so he did not trigger any warning lights."
After that, Aaronson, who is currently suspended and living in Salford, Manchester, gave a number of false details to banks and businesses to avoid routine checks.
In September 1995 he obtained a loan of £1,500 from the TSB Bank giving his false date of birth and said he was unable to provide previous addresses because he'd been living in Australia.
Three months later he was at it again, using the same method to get a further £1,000 loan from the same bank branch in Whitby, the court was told.
Mr Orme said in June 1996 Aaronson acquired a credit facility from Beneficial Bank by falsely stating he had previously lived in Home Office accommodation.
In the same year he also deceived Wagan Finances Ltd into lending him the cash to buy a £11,000 Range Rover after he tricked his way through a credit check by saying he lived at a police training college in Durham: He also hired a Volkswagen Golf from another company in a similar manner.
Mr Orme went on: "He got all these services using false details that were patently untrue."
Aaronson, formerly of High Street, Starbeck, pleaded guilty to five counts of deception and one of using a false instrument, namely the driving licence.
His solicitor, Mr Wilf Anderson, said due to the seriousness of the offences a pre-sentence report would help magistrates deal with the officer.
Bench chairman Mr Keith Brining adjourned the case for a month and said all sentencing options were open, including custody.
