Registration Districts

From the Family Tree Forum Reference Library


The three lists on Genuki ~ GRO Indexes Registration Districts provide the reference numbers of the registration districts for births, marriages and deaths in England and Wales.


  • 1837-1851 (Roman numerals)
  • 1852-1946 (Arabic numerals plus a letter)
  • Reference Numbers for each County


These reference numbers also serve as the Volume identifier in the General Register Office's indexes (at the Family Records Centre in London and many other libraries and family history research centres).

Roman numerals were used for the reference numbers until 1851 when the districts were modified and Arabic numerals plus a letter were used. As the older register indexes are updated the Roman numerals are being replaced by Arabic numerals.
