Texas area codes, metro by metro.
| METRO | AREA CODES | COVERAGE |
|---|---|---|
| Dallas | 214 · 469 · 972 · 945 | Dallas, Plano, Irving, Garland — 945 is the newest Dallas overlay, added in 2021. See the 214 area code guide. |
| Fort Worth | 817 · 682 | Fort Worth, Arlington, and the western side of the Metroplex. |
| Houston | 713 · 281 · 832 · 346 · 621 | Houston, Sugar Land, Pasadena, The Woodlands — 621 is the newest overlay, in service January 2025. See the 713 area code guide. |
| Austin | 512 · 737 | Austin, Round Rock, Georgetown. See the 512 area code guide. |
| San Antonio | 210 · 726 | San Antonio proper — 726 overlaid 210 in 2017. See the 210 area code guide. |
| El Paso | 915 | El Paso and far West Texas. |
| Regional Texas | 254 · 325 · 361 · 409 · 430 · 432 · 806 · 830 · 903 · 936 · 940 · 956 · 979 | Everything between the metros — the Panhandle and Lubbock (806), Waco–Killeen (254), Northeast Texas (903/430), Midland–Odessa (432), Corpus Christi (361), and the Rio Grande Valley (956) among them. |
The list keeps growing: NANPA adds overlays as Texas metros exhaust their numbers — 621 over Houston in 2025, 945 over Dallas in 2021, and 726 over San Antonio in 2017 are the recent ones, and more will follow. Verify the current list before committing a campaign to a code, and remember that overlays are functionally identical to the legacy code they share ground with.
What ships with every Texas DID.
Every Texas metro, one carrier
Dallas to the Rio Grande Valley, numbers are assigned from our own NANPA-allocated inventory — not rented through an upstream reseller who marks up every rate center.
Same-day provisioning for most orders
Name the area code and quantity; most Texas orders are routed, registered, and live on your trunk the same day. Bulk orders across many rate centers may take slightly longer.
CNAM registration included
Your 15-character business name is registered in the CNAM database during provisioning, at no extra charge. It propagates within 24 to 72 hours, so recipients see a name, not a bare number.
A-level STIR/SHAKEN attestation
Every Texas DID is registered in our STIR/SHAKEN database and signed with our own SP-KI certificate. Outbound calls carry A-level attestation — no reseller intermediary, no B-level compromise.
Carrier-direct, not an app subscription
Virtual phone apps bundle a Texas number into a per-user subscription you rent forever. SIPNEX assigns the DID carrier-direct, and it works on any SIP platform — your PBX, dialer, or softphone.
Inbound and outbound on every DID
Each Texas number handles inbound routing and outbound caller ID on the same trunk. No separate number types, no add-on to make the number you answer the number you dial from.
Look local in every Texas market you call.
A Dallas prospect seeing a 214 on the screen answers differently than one seeing an out-of-state code. Local presence dialing puts a caller ID with the recipient's own area code on every outbound call — and Texas, with distinct codes for each metro, rewards doing it properly. A pool of DIDs per target code, rotated to protect number reputation, turns the area code map above into an answer-rate strategy.
SIPNEX provisions local presence pools across every Texas metro from the same NANPA-allocated inventory, with each number CNAM-registered and signed at A-level attestation. The mechanics — pool sizing, rotation, and the compliance lines you must not cross — are covered in our local presence dialing guide.
Port your existing Texas numbers in. Keep dialing.
Send the LOA
Submit a Letter of Authorization and a recent bill copy for the Texas numbers you're bringing. That's the whole paperwork burden on your side.
We submit and schedule
SIPNEX files the port with the losing carrier and locks in a Firm Order Commitment date. Standard Texas ports complete in 7 to 14 business days.
Dial on new DIDs meanwhile
Need to start calling before the port lands? New Texas DIDs provision same day for most orders, so your operation runs while the legacy numbers transfer.
Cut over, keep the number
On the FOC date the number moves to SIPNEX with routing, CNAM, and STIR/SHAKEN registration already in place. No porting fees for US numbers.
What businesses do with Texas numbers.
Multi-market local presence
Dial Dallas with a 214, Houston with a 713, Austin with a 512 — caller ID that matches the recipient's area code gets answered more often than an out-of-state number. See local presence dialing guide.
Campaign tracking numbers
Assign a unique Texas DID to each ad, billboard, or landing page and let the number tell you which campaign made the phone ring. See call tracking service.
Expanding into Texas
Opening a Dallas sales desk or a Houston branch? Put a local number on the website and ad campaigns before the office lease is even signed. See DID numbers service.
Call centers dialing Texas
Build CID rotation pools across the Texas codes you dial into, spread volume to protect number reputation, and keep every DID under A-level attestation. See VICIdial carrier.
