E.118 is an international standard that defines the international telecommunication charge card, for use in payphones, it also defines the Integrated Circuit Card Identifier (ICCID), which is used in SIM cards, including eSIM cards. The standard was first developed in 1988 by what became the Standardization Sector of the International Telecommunication Union (ITU-T) with several revisions having been published since then.

The E.118 standard was first developed by the precursor to the ITU-T, International Telegraph and Telephone Consultative Committee (CCITT, in the French acronym) and it was adopted by its governing body the World Telecommunication Standardization Conference (WTSC), as its 1988 meeting. Since then it has been revised several times by Study Group 1, most recently in 1996.
The Integrated Circuit Card Identifier (ICCID) is a number to international identify callers, called a 'Primary Account Number', used i.a. in SIM cards including eSIM cards. Its layout is based on ISO/IEC 7812. The ICCID is made up of:
- Issuer identification number (IIN)
- Individual account identification (IAI)
- Check digit
E.118 stipulates that the ITU-T updates a list of all current internationally assigned IIN codes in its Operational Bulletins which are published twice a month.
