IGI Batch Numbers for the British Isles and North America

Batch numbers relate to records extracted (indexed) for the International Genealogical Index. Each batch number relates to a specific record and range of years. Knowing more information about what is included in a batch may be helpful for continuing your research.

Knowing the range of years covered by a particular IGI (International Genealogical Index) batch number may help you better understand what data may or may not be indexed in the IGI.

The Parish and Vital Records Index available on microfiche at family history centers has been used to identify what records have been indexed for the IGI. Unfortunately it is only available at family history centers or at the Family History Library in Salt Lake City. There is a partial alternative available on the internet.


 * Hugh Wallis has developed a list of what parishes in the British Isles, provinces in Canada and states in the USA have records in the IGI.


 * OpenGen.net has the batch numbers for the United States, searchable by state and county.

From these Web sites, you can search the IGI for a particular batch number for your county or parish, designating a particular surname.
