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 material at:

which allows you to learn more about what information may be available in the IGI. Any time you search an index it is important to know what was included in the index.
