The municipality lies in the Eifel, indeed on the edge of the Vulkaneifel, on a high plateau between the Alf and Sammetbach valleys.
Oberscheidweiler borders in the south on Niederscheidweiler, in the west on Hasborn and in the north on Mückeln.
The cross on the dexter (armsbearer's right, viewer's left) side refers to Oberscheidweiler's centuries-long allegiance to the Electorate of Trier.
The lily on the sinister (armsbearer's left, viewer's right) side stands for Springiersbach Abbey, for which Emperor Henry IV issued a certificate of confirmation.
The post horn appears as a charge for a more straightforward reason: Oberscheidweiler lay on the old postal route from Trier to Koblenz, known to have been run by the Princely house of Thurn und Taxis in 1840.
