Energy Identification Code

<p>The scheme is supported by a central issuing office (CIO), which function is exercised by the ENTSO-E Secretariat for both the electricity and gas sectors, and ENTSO-E-authorised Local Issuing Offices (LIOs) in Europe. 
As of 2024-12-17, there are 62 LIOs<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
</p><p>EIC consists of 16 characters structured as follows:<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a><a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a>
</p>
<ul><li>2 digits: LIO id</li>
<li>1 letter: resource type as per the table below.</li>
<li>12 chars: LIO-specific identifier, padded on the right with dashes</li>
<li>1 char: checksum</li></ul>
<p>EIC types (see EIC Definitions for more details<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a>):
