Since E.118's issuer identification number is of variable length (it can be 4–7
digits) an ICCID (the serial number
of SIM cards) needs to be matched against a list of known IINs in order to
determine the SIM issuer.
npm install e118-iin-list
``typescript
import { identifyIssuer } from "e118-iin-list";
const issuer = identifyIssuer("89450421180216254864");
if (issuer !== undefined) {
console.log(issuer.companyName); // Telia Sonera A/S
}
`
You can identify issuers directly from your command line:
$ npx e118-iin-list 89450421180216254864
{
"iin": 894504,
"countryCode": 45,
"issuerIdentifierNumber": "04",
"countryName": "Denmark",
"companyName": "Telia Sonera A/S"
}
> _Note:_ if your ICCID is not recognized, please open a new issue
> in this repository.
The numbering of the card to be issued by OAs shall be as follows based on
ISO/IEC 7812-1 (Identification cards – Identification of issuers – Part 1:
Numbering system) and ISO/IEC 7812-2 (Identification cards – Identification of
issuers – Part 2: Application and registration procedures).
The maximum length of the visible card number (primary account number) shall be
19 characters and is composed of the following subparts (see Figure 1):
- Major Industry Identifier (MII);
- country code;
- issuer identifier;
- individual account identification number;
- parity check digit computed according to the Luhn formula (see ISO/IEC 7812-1,
Annex B). In addition to the parity check digit, OAs may incorporate a
validation check device in some location on the card which could be changed
when new cards are issued.
- the Major Industry Identifier (MII) is always 89 (_telecommunication0
purposes_)
- the Country Code is a positive integer (no leading zeros)
- the Issuer Identifier (IIN) is a _string_ (it has leading zeros) and can be
entirely made up of

Process:
1. Export
the database as
Excel spreadsheet and copy and past the table into a Google Spreadsheet
2. Export list of shared country codes (E.164) from
http://www.itu.int/net/itu-t/inrdb/e164_intlsharedcc.aspx?cc=881,882,883 and
filter out CRS records (inactive), add to the spreadsheetlist.csv
3. Export that to CSV and store it as
