Texas area codes
Texas uses 29 area codes. The oldest is 214, in service since 1947; the newest is 621, from 2025. Across them 16,111 of 22,794 possible number blocks are allocated, 70.7% of capacity. 281, 469, 832, 214, 512, 713, 972, 210, 817, 903 and 346 are at or past 95%, which is why new numbers there come from overlays rather than the original code. AT&T holds 36.5% of the 16,111 assigned blocks across the state, ahead of T-Mobile at 9.8%; a further 13.9% sits with CLEC and VoIP holders outside the national carriers. In the 33 days to 30 October 2026, FTC complaints named a Texas caller ID 18,551 times – 8.1% of all complaints in the window, most often 469 with 1,250 (17th of 422 nationally). NANPA has relief planning under way for 956, so another code is coming. The state spans 2 time zones (Central and Mountain); 915 crosses a zone boundary alone. NANPA records 1,714 rate centers across the state's codes.

Block share is share of allocated number blocks, not of subscribers. Complaint counts cover 28 Sep – 30 Oct 2026 and reflect spoofed caller IDs as much as real calls.
How full Texas’s codes are
A code holds at most 786 blocks of 10,000 numbers each. When a code fills up, the administrator does not reclaim numbers – it adds an overlay, and from then on new numbers in the same area come from the new code.
Full or nearly full
621 is in service with no blocks assigned at all, so nobody can hold a number there yet – a caller ID showing one is necessarily spoofed.
Who holds the number blocks
Counted from every assigned block in the state: 16,111 blocks, each with the holder NANPA recorded for it. Percentages are measured, not estimated.
| Holder | Blocks | Share of Texas | Largest in |
|---|---|---|---|
| AT&T | 5,877 | 36.5% | 20 codes |
| Other CLEC / VoIP | 2,239 | 13.9% | 6 codes |
| T-Mobile | 1,582 | 9.8% | 1 code |
| Verizon | 1,378 | 8.6% | – |
| Onvoy | 1,213 | 7.5% | 1 code |
| Lumen | 976 | 6.1% | – |

“Other CLEC / VoIP” is not one company: it is every holder outside the national carriers counted together, which is what resellers and app-based numbers look like in the records. This is allocation, not subscribers.
Spam complaints naming Texas codes
FTC Do Not Call complaints where the caller ID shown was a Texas number, 28 Sep – 30 Oct 2026 (33 days). Caller IDs on spam calls are routinely faked, so these are complaints about the code, not calls proven to come from it.

What is coming next
NANPA has relief planning open for 956 – the step that comes before a new overlay is announced. Watch this code if you need to know whether dialing or new-number availability is about to change.

Time zones
Texas is in Central, Mountain time. 915 covers more than one zone within a single area code, so the code alone does not tell you what time it is there. This code spans 2 time zones.
Frequently asked about Texas area codes
How many area codes does Texas have?
29 in service. They are 210, 214, 254, 281, 325, 346, 361, 409, 430, 432, 469, 512, 621, 682, 713, 726, 737, 806, 817, 830, 832, 903, 915, 936, 940, 945, 956, 972 and 979.
What is the oldest area code in Texas?
214, in service since 1947. Every later code in the state was split off from or overlaid on an existing one.
What is the newest area code in Texas?
621, from 2025, overlaying 346.
Is Texas getting a new area code?
Probably. No new code is assigned yet, but NANPA lists relief planning under way for 956, which is the step before a new overlay is announced.
What time zone is Texas in?
It spans 2: Central and Mountain. 915 covers more than one zone within a single area code, so the code alone does not tell you the time.
Which Texas area code gets the most spam complaints?
469 – 1,250 FTC complaints in the 33 days to 30 October 2026, 17th of 422 codes nationally. Those are complaints about the caller ID shown, and spam callers routinely fake a local-looking number, so this says the code is imitated often, not that the calls come from there.
Which carrier holds the most Texas numbers?
AT&T, with 36.5% of the 16,111 blocks assigned across Texas, ahead of Other CLEC / VoIP at 13.9%. This is allocation of blocks by the numbering administrator, not a count of subscribers – people keep their numbers when they switch carriers.
