Chapter 4: The Legal Requirements of Boating
Your Vessel’s Registration (625 ILCS 45/3)
Requirements for vessel registration vary from state to
state. In Illinois, you must have an Illinois Certificate
of Number (registration) and expiration decals to legally
operate a vessel on Illinois waters. Exceptions to the
requirement to register recreational vessels include:
- Sailboards
- A canoe or kayak owned by a non-profit organization
- A non-powered vessel operated on a private lake
- A vessel owned by the federal or state government
- Vessels properly registered in another state and using
Illinois waters for less than 60 consecutive days
- Vessels documented with the U.S. Coast Guard and using
Illinois waters for less than 60 consecutive days
If your vessel requires registration, it is illegal to
operate or allow others to operate your vessel unless it
is registered and numbered.
Watercraft registration
application forms are available from Illinois
Department of Natural Resources regional offices,
conservation officers, and boat dealers. Boaters
may renew their vessel registrations by phone (1-866-867-3542
or 1-800-867-3542), or online at the DNR
website.
After registering a vessel, an owner will receive
a Certificate of Number (registration card). Federal
law requires that the registration card be available
for law enforcement inspection whenever the vessel
is operated.
Registration is valid for three years. All certificates
expire on June 30 at the end of the three-year
period.
If a Certificate of Number or expiration decal
is lost or destroyed, the vessel owner must apply
to the Department of Natural Resources for a duplicate. |
Certificate of Number
(Registration)
The Certificate of Number must
be carried on board whenever the vessel is operated. |
The owner of a registered vessel must notify the Department
of Natural Resources within 15 days of the following events:
- The owner changes his or her address.
- The owner transfers all or any part of his or her interest
in the vessel.
- The vessel is destroyed or abandoned.
Larger recreational vessels, owned by U.S. citizens, may
also (at the option of the owner) be documented by the
U.S. Coast Guard. (Read more about obtaining the U.S. Coast Guard's "Certificate
of Documentation".) Call the USCG at 1-800-799-8362
for more information.
Displaying the Assigned Number and
Expiration Decals (625 ILCS 45/3-3)
The registration number and expiration decals must be
displayed as follows:
- Number must be placed on each side of the forward half
of the vessel.
- Number must read from left to right on one line, starting
with two capital letters—IL— followed by
a space and four digits followed by a space and two capital
letters. For example: IL 1234 AB. The decal is placed
after a space at the end of the number.
- Letters and numerals must be BLOCK figures at
least three inches high, of a color that contrasts with
its background.
Non-powered canoes or kayaks and federally documented
vessels are not required to display the registration number,
but must display the expiration decal. Check with Illinois
DNR for proper placement of decals on these vessels.
No numerals and letters other than the registration numerals,
letters, and expiration decals may be displayed on either
side of the forward half of any vessel.
 |

PWCs are also required to display
the vessel registration number and expiration decals. |
Your Vessel's Title (625
ILCS 45/3A)
Every vessel that is required to have a Certificate of
Number must also have a Certificate of Title. Federally
documented vessels are exempt from this requirement.
Any boater who owns a vessel without a title must apply
to the Department of Natural Resources for a Certificate
of Title before or at the same time application is made
for a Certificate of Number.
The Department of Natural Resources will not issue, transfer,
or renew a Certificate of Number unless a Certificate of
Title has been issued for that vessel.
If your vessel requires titling, it is illegal to operate
or allow others to operate your vessel unless you have
a Certificate of Title for your vessel.
Hull Identification Number
(625 ILCS 45/3-13)
The Hull Identification Number (HIN) is a unique, 12-digit
number, assigned by the manufacturer.
Hull Identification Numbers:
- Distinguish one vessel from another—the same
as serial numbers distinguish one car from another
- Are engraved in the fiberglass or on a metal plate
permanently attached to the transom
- Should be recorded by the owner and put in a place
other than the vessel in case warranty problems arise
or the vessel is lost or stolen
All vessels built after November 1, 1972, including home-made
boats, must have a Hull Identification Number (HIN). The
HIN is required by federal law and it must appear on the
registration application.
If a vessel has no HIN, or if the manufacturer’s
HIN has been removed, obliterated, or altered, the owner
must apply to the Department of Natural Resources for a
HIN.
