When using the International Genealogical Index, also known by the acronym 'IGI', one will often find a number associated with the entry. This is the 'batch number' indicating the source type of the record or records created in preparing the information for inclusion in the IGI, especially after the LDS ordinances were completed.

Often it can lead to sources for additional information. Some information was gathered from extracting data from microfilms, while other data is from LDS member submissions and the forms used for those. The prefixes in the table below are found as part of the batch number you see with the IGI record for that individual.

After 1991, LDS member submission information was not recorded, so all one has is the name and date information, the film containing the temple record shows little more than what you see on the IGI entry for the individual.

Batch Batch Description Locating the Source
A------ Archive Sealing. Extracted from Family Group Records Collection, Archive Section, or other temple records.
If the IGI sealing date is after 1941: Search the microfilms of the Archive Section of the Family Group Record Collection alphabetically under the husband's name. If the IGI sealing date is before 1942: use the Source Call No. (a microfilm in in Special Collections [restricted access] arranged by the date of the sealing).[1]
C------ Christening or birth record extraction. Names originally from lists of christenings or births in geographic areas, frequently from Parish and Vital Records. The Source Call No. is the book or microfilm call number at the Family History Libray that was the original source. Usually arranged by the date of the christening or birth.[2] The films can be circulated to Family History Centers.
D------ Suspended File. Ordinances delayed for several years. These D------ batch numbers only appear on Patron Notification letters and are accompanied by a different batch number. The accompanying batch number can be used to trace the original source ofthe information.[3]
E------ Early marriage record extraction used for proxy baptisms and endowments. To find the call number for the source marriage record of an E------ batch entry, look under the M------ batch number in the IGI Batch Number Index and find the matching M------ batch number. For example, to find the source call number for batch E005361, look under batch M005361.[4]
F------ Family Entry. Patron submitted family group records. Some dates or places are estimates. Find the F------ batch number in alpha-numerical order on the Source Call No. microfilm.[5]
H------ Ward Record or Deceased Members File of LDS Church. Some ordinances may have been repeated by proxy. The source is data on his LDS membership record when a person dies. To find this source see Deceased Members File under Sources for Verifying Deaths. These films do not circulate to Family History Centers, but are available to the general public at the Family History Library.
