EZ Loader VIN Check
EZ Loader has built boat trailers since 1953 under two active NHTSA WMIs. 1ZE is the Adjustable division in Spokane, Washington (roller, bunk, aluminum, and OEM package lines). 1L8 is the Custom division in Midway, Arkansas — fitted trailers for specific boat brands. Legacy tags sometimes begin with 1DH (Custom parts routing). Parts are not always interchangeable between divisions.
US trailer VINs follow ISO 3779 / FMVSS 565. On modern Adjustable letter VDS, position 4 is series, 5 is trailer type, and 7 encodes length in feet. Custom uses a different character ledger (ORG13215). When enabled, factory VIN lookup can add catalog number, capacity, and GVWR for registered units.
How to Read a EZ Loader VIN
Read positions 1–3 first: 1ZE = Adjustable (Spokane), 1L8 = Custom (Midway). Verify the check digit (position 9) and model year (position 10). For letter-series Adjustable VINs, decode length from position 7 (e.g. R = 24 ft). Older numeric VDS schemes need NHTSA or the factory — do not force modern length tables onto 1980s tags. Confirm both the silver rail sticker and tongue decal before ordering parts.
Frequently Asked Questions — EZ Loader VIN
What does WMI 1ZE mean?
1ZE is EZ Loader Adjustable Boat Trailers, Inc., manufactured in Spokane, Washington. Modern letter VDS encodes series, type, and length.
What does WMI 1L8 mean?
1L8 is EZ Loader Custom Boat Trailers, Inc., manufactured in Midway, Arkansas. Custom VINs use a different position map than Adjustable.
What about WMI 1DH?
1DH is a legacy Custom prefix used for parts routing. It is not in the live NHTSA WMI registry — confirm with EZ Loader Custom before ordering.
Where is the VIN on an EZ Loader trailer?
On a silver sticker on the front passenger-side rail, and on a decal under the tongue. Custom trailers may also stamp the last five digits on the frame near the tongue weld.
Can I look up my trailer at the factory?
EZ Loader offers a public VIN lookup for units in their registration database. It may return catalog number, capacity, GVWR, and dealer name when the VIN is on file.
Why is the check digit invalid?
US trailer VINs should use an ISO 3779 check digit in position 9. An invalid digit usually means a transcription error on the tag or paperwork — confirm against both stickers before registering or ordering parts.
