MIC API request conditions — English translation
Source: 無線局等情報検索 Web-APIのリクエスト条件一覧, version 1.3.0, March 2025, MIC Japanese PDF. Translated 2026-09-17. This translates the request-condition table and search rules (PDF pp. 3–6); revision history and repeated formatting are omitted. Parameter codes are unchanged. The purpose and communication code tables below additionally translate MIC’s search-selector data, with their source linked separately.

| SC | Start count | List, required | Starting record position; decimal digits, up to 10 digits as printed in this table. |
| DC | Number to retrieve | List, required | 1 = 100; 2 = 500; 3 = 10,000. DC=3 requires DA=0. |
| OF | Output format | Both, required | 1 CSV; 2 JSON; 3 XML. |
| OW | Station class | Both, ST=1, required | Up to 6 characters; use the exact station-class code, including underscores in values such as FB_PHS and FX_H. |

| IT | Responsible regional communications bureau | Both | One-character bureau code. |
| HCV | Prefecture / municipality | Both, ST=1 | First five digits of the local-government code. First two identify the prefecture; last three identify the municipality. 01000 = Hokkaido; 01202 = Hakodate. |
| MK | Station purpose | Both, ST=1 | 3-character station-purpose code; see combination rule below. |
| TSNJK | Communication matters | Both, ST=1 | 3-character communication-matters code; see combination rule below. |
| KHS | Type of basic broadcasting | Both, ST=1 | Up to 3-character broadcasting-type code; see combination rule below. |
| FF | Frequency, start | Both | Up to 17 characters including decimal point; see units and search rules below. |
| TF | Frequency, end | Both | Same format as FF. |
| HZ | Frequency unit | Both; required with FF or TF | 1 kHz; 2 MHz; 3 GHz. |
| NA | Licensee / registrant name | Both | Partial match, up to 100 characters before encoding. URL-encode as UTF-8. Multiple names cannot be specified. |
| MA | Call sign | Both, ST=1 | Partial match, up to 12 ASCII alphanumeric characters. |
| FC | Collective frequency/emission designation | Both, ST=1 | Up to 3-character code; see the designation code list. |
| AS | Ship / aircraft name | Both, ST=1 | Partial match, up to 30 characters before encoding, regardless of full-width/half-width characters. URL-encode as UTF-8. Multiple names cannot be specified. |
| DF | Licence / registration date, start | Both | YYYYMMDD. |
| DT | Licence / registration date, end | Both | YYYYMMDD. |
| SK | Sort key | List | Licence search: 1 licensee name, 2 installation/base prefecture (default), 3 station purpose, 4 licence date. Registration search: 1 registrant name (default), 2 responsible bureau, 3 registration date, 4 registration validity period. |
Purpose combination rule: specify either station purpose + communication matters, or station purpose + type of basic broadcasting. If only one component is supplied, that condition is ignored during the search.
Frequency precision: kHz permits 10 integer digits and up to 6 decimal places; MHz permits 7 integer digits and up to 9 decimal places; GHz permits 4 integer digits and up to 12 decimal places. The decimal point counts toward the 17-character maximum.
Frequency search rules — PDF p. 6
| Supplied bounds | Meaning |
|---|---|
| FF only | Frequency greater than or equal to FF. |
| FF=0 only | All frequencies. |
| FF=TF, nonzero | The specified frequency point. |
| FF<TF | Inclusive frequency range. |
| TF only | Frequency less than or equal to TF. |
| TF=0 only | Error. |
| FF=TF=0 | Error. |
| FF>TF | Error. |
Date search rules — PDF p. 6
| Supplied bounds | Meaning |
|---|---|
| DF only | On or after DF. |
| DF=DT | That date only. |
| DF<DT | Inclusive date range. |
| DT only | On or before DT. |
| Invalid format, nonexistent date, or DF>DT | Error. |
Encoding revision — PDF p. 2
Version 1.3.0 removes the character-encoding condition because the encoding is standardized on UTF-8.
Purpose and communication code tables
The following tables translate the current alphabetic code lists in MIC’s
licence-search selector data, as retrieved on 2026-09-17.
The expert search form uses these lists for MK, TSNJK, and
KHS. The API request PDF refers to the station-application code table in
MIC Notification No. 860 of 2004 (平成16年総務省告示第860号).
The selector data also contains older numeric lists marked “旧H26” (former 2014
codes); those historical lists and internal placeholder values are omitted here.
