4 N.C. Admin. Code 11R08-34
Electric membership corporations (including electric "cooperatives" domesticated in North Carolina, both hereafter called "EMCs") will carry the designation "EC" in all of their filings with the Commission, whether under G.S. 62-138(f) or otherwise, together with their respective number designations by the United States Rural Electrification Administration. (Out-of-state EMCs domesticated in North Carolina will also carry immediately following their REA number designation, the letter (s) denoting their respective states, since in several instances the numbers are the same as assigned to North Carolina EMCs.) For example, Randolph Electric Membership Corporation, Asheboro, North Carolina, was originally assigned the REA number 36; Randolph's filings will therefore carry the designation "EC-36"; in like manner, each of the other EMCs will be designated and permanently identified.
