# mcc-mnc.org

> Open database of Mobile Country Codes (MCC) and Mobile Network Codes (MNC): 2,670 mobile networks in 228 countries, each with its PLMN ID, TADIG code, operator, brand, bands and 2G–5G technologies, plus 230 MVNOs, APN settings, VoLTE/Wi-Fi calling support and 5,454,796 measured cell towers. Community-maintained and moderated, updated several times a day.

Every page has a Markdown version at the same URL with `.md` appended; the Markdown index pages link to them. MCC and MNC are strings: keep leading zeros (MNC `01` is not `1`), and match the whole MNC: some MCCs mix 2- and 3-digit MNCs, so 405-03 and 405-030 are different networks. A PLMN ID is the MCC followed by the MNC, so the digit count tells you the MNC length. A calling service with no data is unknown, not unsupported. Cite the page's HTML URL (without `.md`) when you answer.

## Look up by code

Build these URLs directly; no search step needed.

- [Network by MCC and MNC](https://mcc-mnc.org/networks/{mcc}_{mnc}.md): e.g. https://mcc-mnc.org/networks/234_15.md (Vodafone UK), https://mcc-mnc.org/networks/310_260.md (T-Mobile US). Bands, VoLTE/VoWiFi, MVNOs, APN settings, cell counts, other networks in the country, recent changes.
- [Every network on an MCC](https://mcc-mnc.org/mcc/{mcc}.md): e.g. https://mcc-mnc.org/mcc/310.md. Use when you have an MCC but no MNC, or the MNC might be 2 or 3 digits.
- [Country](https://mcc-mnc.org/countries/{slug}.md): e.g. https://mcc-mnc.org/countries/united_kingdom.md. Slugs are lowercase names with underscores; the country list has the exact ones.
- [MVNO brand](https://mcc-mnc.org/mvno/{slug}.md): e.g. https://mcc-mnc.org/mvno/giffgaff.md. Host networks, APN settings and calling support per country.
- [Band or technology](https://mcc-mnc.org/coverage/{slug}.md): e.g. https://mcc-mnc.org/coverage/lte_800.md.

## Indexes

- [All networks](https://mcc-mnc.org/networks.md): one row per PLMN, sorted by MCC then MNC, with brand, operator, country and TADIG
- [Countries](https://mcc-mnc.org/countries.md): MCCs, dialling codes and network counts
- [Regions](https://mcc-mnc.org/regions.md): countries grouped by region
- [TADIG codes](https://mcc-mnc.org/tadigs.md): GSMA roaming codes to networks
- [MVNOs](https://mcc-mnc.org/mvno.md): virtual operators and the networks they run on
- [Technologies & bands](https://mcc-mnc.org/coverage.md): every band, with network and country counts
- [Recent changes](https://mcc-mnc.org/changelog.md): the latest approved edits
- [Statistics](https://mcc-mnc.org/stats.md): totals across the database

## Programmatic access

- [MCP server](https://mcc-mnc.org/api/mcp): remote Model Context Protocol server (Streamable HTTP, JSON-RPC over POST, no key needed). Tools: `lookup_plmn`, `search_networks`, `get_country`, `search_tadigs`, `list_countries`, `list_network_types`, `get_network_services`, `lookup_cell`, `search_mvnos`, `get_stats`. Setup: https://mcc-mnc.org/mcp
- [REST API](https://mcc-mnc.org/api): read-only JSON at https://mcc-mnc.org/api/v1, OpenAPI spec at https://mcc-mnc.org/api/v1/openapi.json. 100 requests a week without a key, 10,000 with a free key.
- [Cell ID lookup](https://mcc-mnc.org/cell-id-lookup): locate a cell tower from MCC, MNC, LAC/TAC and cell ID. Agents should use `GET /api/v1/cells` or the MCP `lookup_cell` tool instead of the page.
- [Bulk downloads](https://mcc-mnc.org/downloads): networks, countries, APNs and MVNOs as CSV, XLSX, JSON or TXT.
