Hamilton Square is the old crossroads village at the center of Hamilton Township, where Nottingham Way meets the Mercerville–Whitehorse road, and 08690 is the eastern half of the township around it — Foxmoor, Rosemont, Creston and the streets off Klockner and Edinburg Roads. It is a township ZIP with a village at its middle, and the two parts deliver quite differently.

How our trucks get here
Deliveries into Hamilton Square run off Nottingham Way, Route 33, Klockner Road, Edinburg Road, Whitehorse–Mercerville Road, Quakerbridge Road, Old Trenton Road and Flock Road.
Little to flag, which is worth saying plainly: driveways, curbs and room to stand are the rule here rather than the exception. The one thing that helps is the development name as well as the street, because Foxmoor and Rosemont both have curved roads that repeat names.

Tanks in Hamilton Square homes
A handful of older frame houses around the crossroads itself, and then the township: capes and split-levels from the 1950s and 60s off Klockner and Whitehorse–Mercerville, and larger colonials in the developments out toward Edinburg and Flock Road. Almost everything has a driveway and most tanks are in a basement or an attached garage, which makes this some of the most straightforward delivery ground in Mercer County.

Source: U.S. Census Bureau, 2019–2023 American Community Survey 5-year estimates, and the 2023 ZCTA Gazetteer. ZIP Code Tabulation Areas approximate postal ZIPs and don’t follow municipal boundaries, so these describe the ZIP rather than the borough or township exactly. The share heating with oil is left out here: the Census sample for this area is small enough that the published margin of error is wider than the estimate is useful, and we’d rather show nothing than a number we can’t stand behind.
Buying heating oil in Hamilton Square
Hamilton Square is a suburban gas market with an oil minority — too small a one for the Census to size precisely. It is a smaller share than the Trenton wards next door, but the houses are bigger and the tanks are further from empty when they are filled, so a typical order here is larger and comes round less often. The 08690 side of the township is also easy to serve, which is exactly the kind of ZIP where a price should be competitive rather than padded for the drive. Prices move daily with the wholesale rack, which is why the number above is today’s and not last week’s. Local dealers compete on this page, so the lowest price is always at the top — we don’t sell placement above a better price.
How much oil do you need in Hamilton Square?
Order a dollar amount, a number of gallons, or ask for a fill — whichever way you actually think about it. You pay only for the gallons that actually go in, and if the tank takes less, your price per gallon doesn’t go up.
Heating oil in Hamilton Square — common questions
Do you deliver heating oil in Hamilton Square, NJ?+
Yes, to 08690. Mercerville is 08619 and the White Horse side of Hamilton is 08610 — both are also covered, but each is priced on its own ZIP.
Is Hamilton Square the same as Hamilton Township?+
Not quite. Hamilton Square is the village and the surrounding eastern section of the township, with its own ZIP code, 08690. Hamilton Township is much larger and spans several ZIPs, which is why you should order against the ZIP on your own mail rather than the township name.
What is the minimum order here?+
100 gallons. Most 08690 houses have a 275-gallon tank in the basement or the garage, and orders here tend to run larger than in the city ZIPs because there is room for a fuller fill.
My tank is in an attached garage. Does that change anything?+
No — a garage tank with an outside fill is one of the simplest deliveries there is. Just make sure the fill is reachable if the driveway is likely to have a car on it.
Why does the price here differ from Trenton, a few miles away?+
Because each ZIP is priced against what is actually being quoted in that ZIP, not against a county average. Nearby towns can and do differ, and the figure on this page is the live one for 08690.
