Answer (Resolution)



All of the International Genealogical Index (IGI) records are available on the FamilySearch website.  While many genealogists found the IGI useful, its mix of community indexed sources and community contributed records meant that not all of its data was equally reliable.  This problem has been addressed by creating two IGI collections, both searchable from the International Collection search page. 

  • Community Indexed IGI

Consists of sources that were indexed by the genealogical community from collections of vital and church records. *They are considered an excellent source of primary genealogical information because they were indexed from the original films. 

Many original IGI records have been migrated, Vital Records (VR) and Extraction Admin System (EASy), to other collections and cannot be found on the IGI search page; use the general search page on FamilySearch to find these records.  The only records found on the IGI search page are Ordinance Data Management (ODM) records.


  • Community Contributed IGI

Consists of personal family information submitted by individuals.  *Many contributions represent conclusions of the submitter and have not always been verified using primary sources.  


There are several search options for locating IGI records.

Batch Number Search


The batch number represents a record group based on specific locality and a time frame. Batch numbers differ between the Community Indexed IGI and the Community Contributed IGI.


1. Community Indexed IGI batch search is very valuable when you want to search for names in a specific locality and time frame. Batch numbers are preceeded by letters.  For an description of batch numbers, see the research wiki articles "IGI Batch Number Descriptions."




This sample of the detail screen shows the batch number.




Add the Indexing project (batch) number into the Batch Number box, and click Search.

2. Community Contributed IGI batch search is very valuable when you want to search for names that were submitted by the same submitter.  Batch numbers, with the exceptions of L batches, will contain only numbers.
