Telnyx phone number blocks and OCNs in the US

Telnyx holds 13 million phone numbers in the United States, 0.7% of the numbers NANPA’s table of 2026-09-27 lists as allocated there, under 1 operating company number (OCN). The carrier a phone lookup names for a number is the holder of the block the number sits in, as the regulator lists it: the original allocation, not the caller, the app or the network that serves a ported number today.

Who Telnyx is

Telnyx, LLC files with the FCC with Telnyx, Inc as its holding company. Telnyx says it runs its services on its own private, global, multi-cloud IP network.

The legal entities NANPA lists

Every holder in NANPA’s table that the brand map groups under Telnyx, by the numbers allocated to it and with its operating company number (OCN), the code the table identifies a carrier by. Names are printed as the regulator writes them. Holdings are counted in numbers, not table rows, because rows differ in size: a central office code (NPA-NXX) is 10,000 numbers and a thousands-block 1,000. A pooled code counts for its code holder only where no thousands-block row of the table covers it, so no number is counted twice.

How a lookup reads these numbers

The North American plan leaves a number’s line type to the holder of its block, so a lookup reads it from the holder: 100.0% of Telnyx’s numbers read as VoIP, 0.0% as mobile, and for 0.0% the holder settles neither, so the line type stays fixed_line_or_mobile.

The reading is Spaw’s classification of each holder: the holder’s regulatory filing (in the US its FCC Form 499 filing type) and its own description, matched on the name the regulator’s table gives it. It is a lower bound, not a measurement of the numbers, and it says what a lookup answers, not what Telnyx is.

The area codes with most of its numbers

Telnyx’s entities hold numbers under 335 area codes. The share is its part of the numbers NANPA lists as allocated under each code.

code	place	numbers	share of the code

618	Illinois	149,000	2.1%

Thousands-blocks in pooled codes

In a pooled US code NANPA assigns the code’s ten thousands-blocks one by one, often to carriers other than the code holder, and a lookup names the holder of the number’s own thousands-block where NANPA lists one. Telnyx’s entities hold 12,917 thousands-blocks: 675 inside codes its own entities hold, 10,353 inside codes of other brands and 1,889 inside codes of holders the brand map does not group, which this page counts but does not name.

code holder’s brand	Telnyx’s blocks inside
Inteliquent	2,410
AT&T	1,712
Lumen	1,233
Verizon	1,208
Bandwidth	875
T-Mobile	780

Other holders hold 4,681 thousands-blocks inside Telnyx’s codes, 415 of them holders the brand map does not group. The largest: Inteliquent 1,629, Verizon 632, T-Mobile 534, AT&T 493, Bandwidth 349, Lumen 210.

Assignments by year

The codes and thousands-blocks the table still lists under Telnyx’s entities, by the year NANPA dates their assignment. A block returned since is no longer in the table, so earlier years read low; 98.7% of the rows carry a date. NANPA dates nothing before 2001 and no retained block.

What this page cannot say

A regulator’s table records the original allocation of each block, never who serves a number today: a number ported away from Telnyx keeps its block, and a lookup still names the block’s holder for it.
The carrier a lookup names is not the caller, the app or the subscriber. Caller ID can be spoofed, so the holder of a calling number’s block may not have carried the call at all.
Spaw does no reverse lookup and names no subscriber: nothing here says who owns or uses any number.
Shares are shares of the regulator’s own table, not of subscribers, lines in service or traffic.
In a pooled US code a lookup names the holder of the number’s own thousands-block where NANPA lists one, otherwise the code holder; Canada’s table is code-level.
The grouping under Telnyx is Spaw’s carrier brand map of 2026-09-24: legal entities, subsidiaries and former names under the brand the network trades as today. Networks change hands, and the map is reviewed at least yearly.

Telnyx and the other brand names on this page are trademarks of their owners, used only to name the networks the regulators’ tables list. Spaw is not affiliated with any of them.
