The container number (BIC code)
The big alphanumeric block — like LCGU 805492 8 — is the ISO 6346 container number: a 4-letter owner code (the last letter is almost always U for freight containers), a 6-digit serial, and a single check digit that validates the whole thing mathematically. Ocean-going boxes must carry it; yard and rental fleets use the same format because every depot system reads it.
The size/type code
45G1 tells you the box: first two characters are length and height (4 = 40 ft, 5 = 9'6" high-cube), the letter-number pair is the type (G1 = general purpose). A 22G1 is a standard 20-footer. It rides under the container number.
The weight panel
MAX GROSS (box + cargo limit), TARE (empty weight), and NET (allowed payload), each in KG and LBS. Required for transport; smart on any container a crane or truck will ever lift.
What a STORAGE container actually needs
A container parked in a yard or on a jobsite isn't regulated like one on a ship. In practice fleets mark: a unit/asset number (readable from the truck), the company panel (logo + phone — free advertising on a 320-square-foot canvas), the weight block if it ever travels, and safety marks — corner chevrons and a height warning on 9'6" high-cubes that can clip canopies.
Ordering container decals
We cut the whole set on commercial-grade vinyl sized for corrugated steel: container ID numbers, weight panels, unit numbers, company logo panels and safety kits. Multi-container fleets get matched layouts, one proof, and volume pricing.
