NumberResearchRecent thousands-block assignments
4,094 blocks assigned in the last 30 days · from the daily NANPA thousands-block report, 09/29/2026
Most carrier growth happens here, not at the prefix level: under number pooling, carriers receive individual 1,000-number blocks (e.g. 626-470-0XXX) within already-assigned prefixes. Assignments are initial assignments — the current serving carrier of individual numbers may differ due to portability.
