Unique Return Identifier
All pre-populated returns will be uniquely identified with a barcode. This will be printed on every side of a pre-populated return, including any continuation sheets.
The barcode contains a digitised image of the following:
the month the return relates to in the format MMYY (for example, 0709)
accounts office reference number in the format 12312345678 (that is, the letter ‘P’ and the check character will be omitted).
The barcode forms a unique return identifier and will assist the matching of pre-populated returns with continuation sheets.
