> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Number of a road in the international E-road network of the UNECE. It has the letter E and one to three digits, written with or without a space. Class A roads have numbers from 1 to 129. Class B roads always have three digits, and those east of E101 start with 0. Do not confuse it with the E number of a food additive (e_number).
