Data: ITU call sign series allocations (via Wikipedia, retrieved Oct 2026). HB0 is used by Liechtenstein; BM/BV and similar B-block prefixes are used by Taiwan; VR = Hong Kong, XX = Macao, 4U = United Nations (standard ITU allocations not in the grouped table). A prefix shows allocation only — it does not verify that a callsign is licensed. Unofficial prefixes in use (e.g. S0, 1A0) are not in the ITU table.数据:ITU 呼号序列分配(经 Wikipedia,2026 年 10 月获取)。HB0 为列支敦士登使用;BM/BV 等 B 段前缀为台湾使用;VR=香港、XX=澳门、4U=联合国(分组表中漏列的标准 ITU 分配)。前缀仅表示分配归属,不验证呼号是否真实有效。使用中的非官方前缀(如 S0、1A0)不在 ITU 表内。
