🦆 Federal Duck Stamp Explained: Who Needs One, Where to Buy It and Where the Money Goes

If you hunt ducks or geese anywhere in the United States, one small piece of paper matters as much as your shotgun: the Federal Migratory Bird Hunting and Conservation Stamp, better known as the Federal Duck Stamp. It’s one of the oldest and most successful conservation funding tools in the world — and a lot of the public marsh you hunt was paid for with it.

This guide covers who needs a stamp, how to buy and carry it, the mistakes that get hunters cited, and where the money goes.

What the Federal Duck Stamp is

The Duck Stamp was created by the Migratory Bird Hunting Stamp Act of 1934, passed during the Dust Bowl years when drought and wetland drainage had pushed waterfowl populations to historic lows. Congress decided that the people who hunt waterfowl should help pay to protect the habitat those birds depend on.

The first stamp, for the 1934–35 season, was designed by the political cartoonist and conservationist Jay N. “Ding” Darling. Since then a new design has been chosen every year through the Federal Duck Stamp Contest, the only juried art competition run by the federal government. That’s why the stamp is also prized by collectors and wildlife artists.

Who needs a Duck Stamp

• Anyone age 16 or older who hunts migratory waterfowl — ducks, geese, brant and swans where a swan season exists — must carry a current, valid Federal Duck Stamp.
• The federal stamp is required in addition to your state hunting license, any state waterfowl stamp and HIP certification. A state stamp never substitutes for the federal one.
• Hunters under 16 don’t need a federal stamp, though they still need whatever license and HIP registration their state requires.
• You do not need a Duck Stamp to hunt doves, woodcock, snipe, rails or other migratory birds that aren’t waterfowl — but you do need HIP certification for those (see our HIP guide).

Wardens on National Wildlife Refuges check stamps routinely, especially on opening weekends and at popular blinds and boat ramps.

Validity: July 1 to June 30

Each stamp is valid from July 1 through June 30 of the following year — matching the federal migratory bird hunting year, not the calendar year. A stamp bought in September 2026 covers the whole 2026–2027 season, including early teal and goose seasons that open in September and late seasons that run into January and February.

A common mistake is carrying last year’s stamp into a September early season. If it’s after June 30, last year’s stamp is expired.

Sign it — or it isn’t valid

The federal regulation is simple and strictly enforced: you must sign your name in ink across the face of the stamp before you hunt. An unsigned stamp is treated as invalid. Sign it the day you buy it, then carry it with you whenever you hunt waterfowl.

Where to buy one

You can buy a Federal Duck Stamp from several places:

• Many U.S. Post Offices
• Sporting-goods stores and license vendors, including big-box outdoor retailers
• Your state’s online license system, many of which sell the federal stamp as an electronic E-Stamp
• Online from the U.S. Postal Service and other official federal stamp vendors

The E-Stamp

Most states now sell an electronic Duck Stamp alongside your license. The E-Stamp is valid immediately and appears on your license or a printed receipt. It’s valid for 45 days from purchase; during that time the physical stamp is mailed to you, and after the 45 days you must carry the signed physical stamp. If your stamp hasn’t arrived before the E-Stamp period ends, contact the vendor before you hunt.

How much it costs

The price is set by Congress, not by the Fish and Wildlife Service. For recent seasons the stamp has cost $25. Always confirm the current price when you buy — and remember that the price is the same whether you hunt one day or every day of the season.

Where the money goes

This is the part that makes the Duck Stamp special. Ninety-eight cents of every dollar from stamp sales goes into the Migratory Bird Conservation Fund, which is used to buy or lease wetland and grassland habitat for the National Wildlife Refuge System. Since 1934, stamp sales have raised more than a billion dollars and protected millions of acres.

Much of that land is open to hunting today:

• Many National Wildlife Refuges were purchased in whole or in part with stamp revenue.
• Nearly all of the Waterfowl Production Areas in the Prairie Pothole Region — small, walk-in tracts of marsh and grass — were bought through the Small Wetlands Acquisition Program funded by Duck Stamp dollars. Browse them in our WPA directory.
• Stamp dollars also buy conservation easements that protect wetlands on private land. Those easements stay private — they’re not open to public hunting.

In our 2026–2027 data, 336 refuges and districts list waterfowl hunting, and there are 3,251 named WPAs covering about 815K acres.

Your stamp is also a refuge pass

A current Federal Duck Stamp gets you free entry to any National Wildlife Refuge that charges an entrance fee. That’s why many birders, photographers and non-hunters buy a stamp every year — it’s a pass and a conservation donation at the same time.

The Junior Duck Stamp

The Federal Junior Duck Stamp program is an art and conservation education program for students in kindergarten through high school. Students enter artwork in state and national contests, and the winning design becomes the Junior Duck Stamp, which is sold to support conservation education. It isn’t a hunting license, but it’s a great way to introduce kids to waterfowl and wetlands.

Common Duck Stamp mistakes

1. Not signing the stamp. This is the most common citation. Sign across the face in ink.
2. Using last season’s stamp during a September early season.
3. Assuming a state stamp is enough. You need both where your state requires one.
4. Letting the E-Stamp lapse. After 45 days you need the physical stamp.
5. Leaving it in the truck. Carry it while you’re hunting, not just while you’re driving to the marsh.

Quick checklist for waterfowl hunters

• State hunting license and any state waterfowl stamp
• Federal Duck Stamp (16+), signed in ink — or a valid E-Stamp
• HIP certification for the state you’re hunting
• Nontoxic shot only — no lead shells in your possession while hunting waterfowl
• A plugged shotgun holding no more than three shells
• Refuge permit or signed brochure, if the refuge requires one (permit guide)
• The legal shooting hours for your exact location and date
