The EIC is based on fixed length alphanumeric codes which can be broken down as follows:
A 2-character number identifying the Issuing Office assigned by ENTSO-E;
One Character identifying the object type that the code represents;
12 digits, uppercase characters or minus signs allocated by the issuing office;
1 check character to ensure the code validity.
Valid characters of an EIC code are A-Z, 0-9 and “-“.
