Disc number

Disc numbers, or ujamiit or ujamik in the Inuit language, were used by the Government of Canada in lieu of surnames for the Inuit and were similar to dog-tags.

Prior to the arrival of European customs, the Inuit had no need of family names, and children were given names by the elders. However, by the 1940s the record-keeping requirements of outside entities such as the missions, traders and the government brought about change. In response to the government's needs, they decided on the disc number system.

The discs were roughly an inch across, burgundy, and made of pressed fibre or leather. They had a hole "to be threaded with a caribou thong and sewn into a parka for safekeeping", or they could be worn around the neck. The discs were stamped with "Eskimo Identification Canada" around the edge and the crown in the middle. Just below the crown was the number. The number was broken down into several parts, "E" for Inuit living east of Gjoa Haven and "W" for those in the west. This would be followed by a one or two digit number that indicated the area the person was from. The last set of numbers would identify the individual. The discs were used in the Northwest Territories (which, at the time, included present-day Nunavut) from 1941 until 1978.

Thus a young woman who was known to her relatives as "Lutaaq", "Pilitaq", "Palluq", or "Inusiq", and had been baptized as "Annie", was under this system to become "Annie E7-121".

Today carvings and prints produced by Inuit artists may be seen with the disc number on them. The Inuit singer Susan Aglukark recorded the song E186 in 2000 on her album Unsung Heroes. Lucie Idlout recorded a CD called E5-770, My Mother's Name in 2005. For the most part, Inuit today do not miss the passing of the numbers, although some Inuit consider their discs to be personal artifacts of sentimental value.
