MCC/MNC Lookup — Global Mobile Network Code Database

The assignment process happens at two levels:

• MCC Assignment: The ITU (International Telecommunication Union) assigns Mobile Country Codes to countries and territories. Each country typically receives one MCC, assigned by the Director of the ITU Telecommunication Standardization Bureau (TSB).
• MNC Assignment: Within each country, the national telecommunications regulatory authority assigns Mobile Network Codes to individual mobile operators. For example, in the USA it's the FCC, in Canada it's the CRTC through the Canadian Numbering Administrator, and in the UK it's Ofcom.

After national authorities assign MNC codes to operators, they report these assignments back to the ITU, which publishes them in the bi-monthly Operational Bulletins. This creates a global registry of all MCC+MNC combinations that we track in our database.

The GSMA (GSM Association) is the global industry body representing mobile network operators. While the ITU handles MCC/MNC assignments as described above, the GSMA plays a complementary role in the mobile ecosystem:

• Roaming & Interconnect: Operators must register with the GSMA to participate in international roaming agreements. The GSMA maintains its own registry (the TADIG database) that tracks which operators are active on global networks.
• Brand Names: The GSMA's TS.25 specification maintains a list of official consumer-facing brand names for each MCC/MNC pair — the name that actually appears on a user's phone (e.g. "T-Mobile" rather than the full legal entity name published by the ITU).
• Standards: The GSMA defines technical and operational standards for GSM, LTE (4G), and 5G networks, including how MCC/MNC codes are used for network selection and roaming.

In practice, both registries are needed for a complete picture: the ITU is the authoritative source for code assignments, while the GSMA provides the brand and operational context used by devices and roaming partners.

The Brand column shows the consumer-facing name of each operator — the name that typically appears on a phone's status bar — rather than the formal legal name published in ITU bulletins. Brand data is sourced from:

• GSMA TS.25: The primary source. This GSMA specification maps MCC/MNC pairs to their official brand and display names as registered by operators for international roaming.
• Community references: For operators not covered by GSMA data, we supplement with well-known community reference sources to maximise coverage.

Because ITU bulletins and the GSMA registry don't always update in sync, some newer or recently renamed operators may not yet have a brand name assigned. Brand data is not part of the official ITU dataset and is provided on a best-effort basis.

While the ITU does publish MCC/MNC data, there are several challenges with using their publications directly:

• Infrequent Full Lists: The ITU publishes complete registry lists very infrequently. Their bi-monthly Operational Bulletins typically only show changes (additions, modifications, deletions) since the last full publication, making it difficult to maintain an up-to-date complete database.
• Manual Aggregation: To get current data, you'd need to manually download and process dozens of bulletin PDFs, track which codes were added or removed, and apply those changes to the last full list—a time-consuming and error-prone process.

This website solves these problems by:

• Continuous Updates: We automatically aggregate updates from every ITU Operational Bulletin, maintaining a living database that's always current.
• Easy Access: Search by country, operator, or code with instant results—no need to dig through PDF documents.
• Developer-Friendly API: Integrate MCC/MNC data directly into your applications with our REST API.
• Multiple Formats: Download the complete database in CSV or JSON format for offline use.
• Visual Tools: Explore network coverage worldwide with our interactive map.
• Full Transparency: Every code links directly to its source ITU bulletin, so you can verify the data yourself.

Use the search box above to search by country, operator name, or specific MCC/MNC values. You can also browse by country using our interactive world map, or download the full database as CSV or JSON.

To see your exact PLMN code directly on your phone, use your device's built-in field test mode:

• iPhone: Open the Phone app and dial *3001#12345#* then tap Call. This opens Field Test mode. Look for Serving Cell Info → MCC and MNC.
• Android: Dial *#*#4636#*#* to open the Testing menu, then tap Phone Information. Your PLMN is shown as a 5–6 digit string (first 3 digits = MCC, remaining = MNC). Alternatively, go to Settings → About Phone → Network or SIM Status.

Yes! The database and API are completely free to use, including for commercial applications. You can access the data through our website, download it in CSV/JSON formats, or integrate it via our REST API.
