Most licensed septic contractors cannot be found online
We looked up 3,963 state-licensed septic contractors on Google, one at a time. 321 of them, 8%, had a business profile with the same phone number the state has on file. Counting the 228 we had already found, the share is 13%.
What we found
Every state in this study licenses the people who install and pump septic systems, and each publishes the roster. A homeowner never sees that roster. They search Google, and Google shows whoever has a profile. In September 2026 we checked how much those two lists overlap. They barely do.
| State | Licensed contractors searched | Found with a matching phone | Share |
|---|---|---|---|
| Arkansas | 1,042 | 43 | 4% |
| Missouri | 825 | 94 | 11% |
| Oklahoma | 283 | 43 | 15% |
| Tennessee | 1,813 | 141 | 8% |
| All four | 3,963 | 321 | 8% |
Why the other 92% did not match
| Result of the search | Contractors | Share |
|---|---|---|
| A Google profile came up, but it lists no phone number | 1,549 | 39% |
| A Google profile came up with a different phone number | 1,589 | 40% |
| Nothing came up at all | 484 | 12% |
The first two rows need care. A search for a small contractor by name often returns some other business, so a profile with no phone or a different phone is frequently not the contractor at all. Read them as "we could not confirm this licensee on Google", not as "this licensee has a bad listing".
Why it matters
Septic work is licensed because a bad install contaminates groundwater and replacing a failed system runs $3,600 to $12,500. The license is the consumer protection. If six in seven license holders are invisible where people actually look, the search results are filled by whoever markets hardest, licensed or not, and the rural installer with a clean record gets no calls from anyone new to the county.
Method
- Source lists: the active septic installer and pumper rosters published by each state agency (Arkansas Department of Health; Missouri Department of Health and Senior Services; Oklahoma Department of Environmental Quality; Tennessee Department of Environment and Conservation).
- Included: licensees with an active license and a phone number on the roster, that we had not already matched to a Google profile. The 228 licensees already matched and listed on SepticNear before this run are not in the table. Adding them gives 549 of 4,191, or 13%, which is the headline figure.
- Search: one Google Maps search per licensee, by business name, town and state, top result only.
- A match required the ten digit phone number on the Google profile to equal the phone number on the state roster. A different trade name with the same phone counted as a match.
- Run dates: September 20, 2026. Texas is excluded because its roster carries no phone numbers.
- Four matched businesses were marked permanently closed by Google and are not listed on SepticNear.
