If you’re buying a home in Eagle, ID, here’s something that simplifies your search right away: the entire city operates under a single zip code. As of mid-2026, the median sale price in the area sits at roughly $874,500 – a figure that reflects just how much demand has built up in the Boise metro. Knowing how the postal map lines up with city limits, school zones, and county services will save you real confusion during the buying process.

The Primary Zip Code for Eagle, ID

Eagle runs on one zip code: 83616. That code covers the full incorporated city and spills into some surrounding unincorporated areas, and the United States Postal Service uses it for every residential and commercial delivery in town.

According to recent demographic data, the 83616 zip code has a population of approximately 33,860 residents. One code for the whole community means no guesswork when you’re setting up utilities or updating your mailing address after closing.

Areas Covered by 83616

The 83616 boundary covers a lot of ground – flat stretches along the Boise River, and foothills terrain to the north. Eagle Island State Park, a well-used outdoor recreation destination, falls within it. So does Two Rivers, a premier riverfront neighborhood near the Boise River that sits entirely inside the 83616 boundary and anchors the luxury end of the local market.

Mapping the Eagle Zip Code Boundary

Pull up a postal map of 83616 and you’ll see the boundary extend well past the downtown commercial center – north into the foothills, south toward the river, edging up against neighboring communities across the Treasure Valley.

One thing worth keeping straight: a zip code boundary and a city limit are not the same line. Some properties carrying an 83616 mailing address actually sit on unincorporated county land. That distinction matters because it affects which municipal services you receive and what your tax rate looks like.

Finding Your 9-Digit Zip Code

The five-digit 83616 gets your mail to the right post office. The USPS then uses a ZIP+4 code to route it to your exact delivery point – a specific city block, apartment building, or cluster of mailboxes.

You can look up the full 9-digit code for any Eagle address through the official USPS address lookup tool online. It speeds up delivery and shows up as a requirement on a surprising number of financial and legal documents.

What County is Eagle Located In?

Eagle, ID sits entirely within Ada County – the most populous county in the state and the administrative hub for the region. Property taxes, vehicle registrations, county court matters: all of it runs through Ada County offices.

Zoom out a level and Eagle is part of the Boise City, ID Metropolitan Statistical Area, which most people just call the Boise metro. A lot of Eagle residents commute into Boise or other Ada County cities for work.

Telephone Area Codes for the Region

Eagle operates under the 208 area code, which historically covered all of Idaho. Population growth brought a second option: the 986 overlay code. Both 208 and 986 serve the 83616 zip code, and because of the overlay, you’ll dial the full ten digits even when you’re calling someone across town.

Real Estate and Living in the 83616 Zip Code

Eagle prices run higher than most of Ada County. As of mid-2026, the median sale price in the 83616 zip code is approximately $874,500, with roughly 292 active listings on the market at any given time.

Homes are sitting for about 53 days before going under contract, and with 3.3 months of housing supply available, you’ll have a reasonable window to look at a few options before committing. That said, well-priced homes are still closing at about 98.8% of list – so don’t expect sellers to absorb lowball offers.

Neighborhood Variations and Pricing

Prices shift considerably depending on where you are within 83616. Foothills properties to the north tend to carry a premium for acreage and views. Closer to the town center, you’ll trade some of that elbow room for easier access to shops and services.

Two Rivers is the clearest example of the luxury ceiling – large lots, river access, and price points that run well above the zip code median. Whatever your target area, pull the recent sales data for that specific neighborhood rather than leaning on the overall 83616 figure alone.

Does having an Eagle, ID zip code mean the property is officially within city limits for municipal water and sewer?

Do home insurance rates or property taxes differ if my house is located in the rural foothills portion of the Eagle zip code?

Yes. Homes in the unincorporated foothills may fall under different fire districts or county tax jurisdictions than properties inside the city limits, so both property taxes and insurance rates can vary within the same zip code.
