The SDLT unique transaction reference number is a unique code assigned to each property transaction that is subject to Stamp Duty Land Tax in the UK. It is used by HM Revenue and Customs to identify and track the transaction throughout the stamp duty payment process.
This reference will always be made up of 9 numbers and 2 characters. You can find this on your paper return or on your electronic SDLT5 certificate.
