Footnotes ...
| <1> | If you're interested in how the shape of California's counties, including Humboldt, have changed over time, we recommend the Atlas of Historical County Boundaries. |
| <2> | A demonym is the name for a resident of a community which is usually derived from (or is related to) the name of that community. In other words, it's how the residents of Trinidad refer to themselves. It's important to note that there aren't any rules for taking a city's name and turning it into a demonym. A demonym is informal and while the majority of Trinidad may use one name, keep in mind that others may use something different. |

The boundaries of the ZIP Code can be changed, re-assigned, eliminated or overlapped with other ZIP Codes.

When looking for a ZIP Code, whether Trinidad or elsewhere, it's always best to check the website of the United States Postal Service (USPS). |
