The short answer: As of October 29, 2026, Neighborhood Registry has read the license record of every insurance agent ranked below at Texas Department of Insurance and found each license Active. 7 insurance agents on the Irving service roster hold licenses we checked in October 2026; 7 are ranked here. One fact stated up front: no Irving insurance agent has claimed a Registry profile yet, so every name below sits in the License-Checked tier — licenses verified at the authority, profiles not yet maintained by the pros. The first Irving insurance agent to claim and verify a profile takes the top tier in the next edition, under the same published rules. Until then, this page is the only Irving insurance agent ranking that prints the license number and check date behind every name.

How this ranking works
Most “best insurance agents in Irving” lists are assembled from advertising placements and review counts copied from other websites. This ranking is assembled from exactly one thing: the license record at the issuing authority, read directly by Neighborhood Registry.
- Eligibility. An insurance agent is eligible only if we have read their record in the authority’s own system and found the license Active. No one can pay to be listed, apply for a rank, or be added by request.
- Tier A — Verified & Claimed. The license is verified at the authority and the pro has claimed their Registry profile, confirmed their details, and maintains it. Tier A always ranks above Tier B.
- Tier B — License-Checked. We have read the license at the authority and found it Active, but the pro has not yet claimed their profile.
- Order inside a tier is mechanical and published: (1) neighborhood seats held in Irving; (2) most recent authority check; (3) time on the Registry (first-verified date); (4) alphabetical. Every input to every score is printed in the entries above.
- Freshness. Licenses are re-checked weekly and formally re-verified every 12 months. A license that lapses or is suspended removes the pro from this ranking at the next re-check — not at the next edition. This page is re-issued monthly; this is the October 2026 edition, built from checks dated October 2026.
Full method: How We Verify — Every check is written to the public verification ledger.
How to verify a Texas insurance agent’s license
Use the Texas Department of Insurance license search at tdi.texas.gov: search by name or license number and confirm the license is Active and appointed for the lines being sold. TDI licenses agents by qualification — general lines (property and casualty), general lines (life, accident and health), personal lines, and others — and the agent must hold the qualification for the policy in front of you.
Irving, in numbers
- Population and housing (Irving city): Irving counted an estimated 257,076 people on July 1, 2025 (U.S. Census Bureau QuickFacts V2025), up 0.1% from the April 1, 2020 Census count of 256,684 — a mature, essentially flat-growth inner suburb. The median value of owner-occupied housing units was $315,600 in 2020-2024, and the owner-occupied rate was 38.1% — Irving is a renter-majority city, with median gross rent of $1,619 (2020-2024).
- Schools: there is no single Irving district. Three districts serve Irving addresses — Irving ISD (most of the city) rated C, Coppell ISD (the northern Valley Ranch area) rated A, and Carrollton-Farmers Branch ISD (the western edge) rated B (82) in the Texas Education Agency’s 2025 accountability ratings. Verify the district for a specific address with the district or on TEA’s TXschools.gov.
- Taxes (Tax Year 2026, per $100 of taxable value): for a city-limits parcel in Dallas County, the worked stack is Dallas County $0.248650 + Parkland Hospital District $0.212000 + Dallas College $0.106575 + City of Irving $0.589100 + the school district — $2.144725 in Irving ISD ($0.988400), $2.142025 in Coppell ISD ($0.985700), and $2.104425 in Carrollton-Farmers Branch ISD ($0.948100), before any special district (Dallas Central Appraisal District TY2026 table). The Dallas County component is subject to a November 3, 2026 voter-approval election; if voters reject it, those totals fall to $2.120725, $2.118025, and $2.080425. Special districts are per-parcel — a parcel inside the Dallas County Utility & Reclamation District (Las Colinas area) adds $0.685657 — and a small Tarrant County sliver of the city carries Tarrant County entities instead, for which no stack is stated here.
- Insurance angle: Irving’s renter-majority tenure (38.1% owner-occupied, Census 2020-2024) makes renters and landlord coverage a first-order local market, and 24.0% of Irving residents under 65 lacked health insurance in 2020-2024 (U.S. Census Bureau QuickFacts), versus 9.6% nationally.
- On this Registry: 7 insurance agents serving Irving hold licenses read at the authority in October 2026; the insurance agent seat is unclaimed.

How do I verify a Texas insurance agent’s license?

What does a Texas insurance agent’s license actually cover?
TDI licenses agents by qualification — for example general lines property and casualty, general lines life accident and health, or personal lines — and an agent may only sell the lines their license covers, for insurers that have appointed them. License-Checked on this page means Neighborhood Registry read the agent’s TDI record and found it Active in October 2026; it is a statement about the license, not about price or service quality.
