Other villages and farm areas in the municipality included Sjøåsen, Statland, Tøttdalen, and Sverkmoen.

This name originally comes from the old Elda farm (Old Norse: Eldueið or commonly shortened to Eið) since the first Eid Stave Church was built there.

The passage was much easier in olden times as the sea level was higher and the waterways more numerous, but as recently as 2004 a boatdrag was done to commemorate the old traditions.

On 3 November 1917, a royal resolution changed the spelling of the name of the municipality to Namdalseid, removing the definite form ending -et.

The official blazon is "Per pale trefly-counter-trefly argent and vert" (Norwegian: Kløvd av sølv og grønt ved kløverbladsnitt).

The background on the left side of the line has a tincture of argent which means it is commonly colored white, but if it is made out of metal, then silver is used.

The clover leaf shapes and the colors were chosen to symbolize the agriculture, landscapes, and nature within the municipality.

The municipal council (Herredsstyre) of Namdalseid was made up of 19 representatives that were elected to four year terms.

Here is a list of people who held this position:[33][34] Being mainly an agricultural municipality, Namdalseid struggled with a decline in population, as fewer and fewer people find they can make a living growing crops and raising cattle.

Having one of the best small-salmon (grisle) rivers in Trøndelag, Namdalseid is a haven for fly fishing and attracts many fishermen every year.

In addition to fishing many visit Namdalseid to experience the beautiful mountain scenery and to do some hunting.
