The area codes of Kentucky

Each code with the place its page names, the year or day NANPA’s NPA report puts it in service, the codes it shares its area with, and the central office codes the NANPA central office code report allocates under it whose rate centre is in Kentucky. A rate centre is where the regulator recorded a code, not where a subscriber is.

code	place	in service	overlays	codes here	assigned, 12 months
270	—	1999-04-19	364	768	3
364	—	2014-03-03	270	72	4
502	Louisville, KY	1947	761	734	11

761	—	planned	502	0	0
859	—	2000-04-01	—	563	5

A year alone means NANPA’s date is 1 January of that year, which it uses where it records no day.

Overlays and new area codes

270 and 364 serve one area: a number there can carry either code, so the area code alone does not place a number more precisely than the area.
761 is assigned and not yet in service and will share its area with 502.

What the NANPA central office code report holds for Kentucky

area codes	6 (1 not yet in service)
allocated codes	2,772 central office codes, 10,000 numbers each
rate centres	372
pooled codes	1,962 (70.8%)
codes assigned since 2025-09-28	33
thousands-blocks assigned since 2025-09-28	348

A pooled code is split into thousands-blocks of 1,000 numbers that other carriers may hold. The twelve months run to the table’s own date, so the figures change only when the table does.

Allocated codes by network brand

Each code is counted under the holder the NANPA central office code report lists for it, grouped under today’s network brand. That is the code’s original allocation, never who serves a number today, since numbers move between carriers, and the shares are shares of the regulator’s table, not of subscribers or traffic. In a pooled code the thousands-blocks can be held by other carriers; this counts the code’s holder.

brand	codes	share
AT&T	843	30.4%
Windstream	339	12.2%
Inteliquent	337	12.2%
Verizon	243	8.8%
T-Mobile	212	7.6%
Lumen	205	7.4%
Charter	79	2.8%
altafiber	57	2.1%
Not under a listed brand (71 holders)	457	16.5%

Where these figures come from

The codes, rate centres, pooling and assignment dates are counted from the NANPA central office code report of 2026-09-27, and the area codes, overlays and in-service dates from NANPA’s NPA report of 2026-09-27. Counts only: no row of either file is republished here. The publisher, its files and its terms are on the data source page. Every area code of the United States is on the United States page, the codes put in service lately or still to come across North America on new and upcoming area codes, and any number can be read on the free phone number lookup.
