A single prefix is 10,000 numbers, but under pooling its ten 1,000-number blocks are often split across different carriers — use the blocks link on any row (or the thousands-block view above) to see which carrier holds which block. Assignments are initial assignments; the current serving carrier may differ due to portability.
