区号常见问题

什么是区号?

区号是北美电话号码开头的 3 位数前缀,用于标识号码注册的地理区域或费率中心。在美国,区号由 NANPA(北美编号计划管理员)管理。

如何找到电话号码的区号?

在标准美国 10 位数电话号码 (NNN) NNN-NNNN 中,前三位 — (NNN) — 是区号。对于 11 位数国际格式 (+1 NNN NNN-NNNN),跳过开头的 1 并读取接下来的 3 位。您也可以将完整号码粘贴到上面的搜索中,我们会为您提取区号。

为什么有些地方有多个区号(叠加)?

当一个地区其原始区号中可用的电话号码用完时,NANPA 会添加叠加 — 服务于同一地理区域的第二个区号。例如:亚特兰大由 404、470、678、770 和 943 服务。叠加需要 10 位拨号进行本地通话。

同一城市的两部手机可以有不同的区号吗?

可以。手机号码在所有者搬家时保留其原始区号,叠加意味着同一城市的新号码可能被分配不同的代码。旧金山相邻的两部手机可以拥有 415、628 或其他地方的任何蜂窝代码。

800、888、877 区号是美国位置吗?

不是。以 800、888、877、866、855、844、833 开头的号码是免费号码,而非地理区号。它们路由到北美任何地方的企业或服务。NumLocation 在此目录中专注于地理区号。
