Other larger villages in Eid included Mogrenda, Stårheim, Haugen, Kjølsdalen, Heggjabygda, and Lote.

[7] On 1 January 1867, the eastern district of Hornindal was separated from Eid to form its own municipality.

Eid Municipality gained all of Davik that was north of the Nordfjorden and east of and including the village of Lefdal.

[8]) All of Hornindal municipality west of and including the villages of Navelsaker and Holmøyvik (population: 310) was also merged into Eid.

Then on 1 January 1992, the village of Lote and its surrounding area (population: 152) was transferred from Gloppen Municipality to Eid.

[9][10] The municipality (originally the parish) is named after the Eidsfjorden (Old Norse: Øygir) since it is a central geographical feature of the area.

The name of the river was probably derived from the word aug or ǫfugr which both mean "turned the wrong way" or "backwards".

The official blazon is "Gules, a horse head couped Or" (Norwegian: På raud grunn eit gull hestehovud).

The charge has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

The municipal council (Kommunestyre) of Eid was made up of 29 representatives that were elected to four year terms.
