How this works and its limits
Runs in your browser: what you enter stays on your device and is never uploaded.
Records combine open MCC-MNC datasets with reference rows we enter and check by hand; each row shows its source and the date it was verified. Where sources disagree, we show the difference instead of hiding it.
Operator names are public reference data and say nothing about any partnership. Searches and IMSI decoding run in your browser, and the dataset is published under CC BY-SA 4.0.
Data sources and licences
Operator names, brands and codes shown here are public reference data compiled from national regulators and other public sources. Their appearance does not indicate any partnership, endorsement, agreement or connectivity between unicomam.com and the named operators. All trademarks belong to their owners. Data is provided “as is” with no warranty; verify against the official source before relying on it for routing, billing or compliance decisions.
Regulatory information is for reference only and is not legal advice; check the regulator link and the “last verified” date.

What MCC and MNC codes are
A mobile country code (MCC) and a mobile network code (MNC) together identify one mobile network. Written as MCC-MNC, or run together as a PLMN identity, the pair forms the first five or six digits of every IMSI, the subscriber identity stored on a SIM or eSIM profile, and networks broadcast it so that devices know which network they are on.
The ITU assigns MCCs to countries and regions under Recommendation E.212, and each country assigns MNCs to its operators. Some countries use two-digit MNCs and others three, and a few have both, so 334020 reads as MCC 334 and MNC 020 in Mexico, while 72405 is MCC 724 and MNC 05 in Brazil. Leading zeros matter: 02 and 002 are different codes.
Codes outlive brands. Operators receive extra codes for new networks, for separate IoT or test networks, or through acquisitions, and many keep the codes of companies they bought. A code can also be returned and stay unused for years. That is why one operator often appears under several codes, and why the brand in a code table can differ from the company name on the assignment.
Engineers meet MCC-MNC codes when they read network and roaming logs, set up steering or roaming lists, route SMS by the network a number belongs to, or prepare an eSIM or multi-IMSI profile. Decoding the first digits of an IMSI shows the home network of a SIM; it says nothing about where the device is or which network it is attached to at the moment.
Public code tables differ because each source updates at its own pace. A dated source on every record matters as much as the code itself: check the status and the date, and confirm with the regulator or the operator before you rely on a code for routing or billing.
