AllowUsually 2 to 5 minutes

Before you start

  • An SBI is a Single Business Identifier issued by the Rural Payments Agency.
  • It contains exactly 9 digits.
  • It is not a Customer Reference Number (CRN), County Parish Holding (CPH) number or trader SBI.

Step by step

  1. 1

    Check RPA correspondence

    Look at recent letters or emails sent by the Rural Payments Agency. The main SBI appears on most correspondence about the business.

  2. 2

    Or use Rural Payments

    Open the official Rural Payments sign-in, select the correct business and look in Business details.

  3. 3

    Check all 9 digits

    Copy the number carefully. AcreTrace accepts digits only and will not accept a CRN or other reference.

  4. 4

    Return to AcreTrace

    Open Field Register, choose Import official boundaries and enter the SBI. AcreTrace never asks for the Rural Payments password or security code.

  5. 5

    If you are an agent

    Use the authorised client business's main SBI, not your agent CRN. Complete Defra's agent acceptance requirements in the import wizard.

If you get stuck

Choose SBI help at any stage of the AcreTrace import wizard for the same official links and RPA contact buttons.

If the SBI cannot be found or does not work, contact the RPA on 03000 200 301, Monday to Friday, 8:30am to 5pm except bank holidays.

If the business has not been registered, use the GOV.UK registration guidance or call the RPA helpline.
