The symbol itself cannot be typed; check that a wheat-ear IPPC symbol sits to the left of these codes inside a bordered box.
What the decoder checks
It looks for an ISO 3166-1 two-letter country code, a hyphen, a producer or treatment-provider code and one of the four treatment codes from ISPM 15 Annex 1: HT, DH, MB or SF. It flags UK, which should be GB, codes that are not ISO countries, and methyl bromide on an EPAL-branded pallet, which EPAL prohibits. It also separates an EPAL licence–year–month marking if you typed one.
It does not check the registration against any database, because national plant protection organisations publish their registers in different ways or not at all. Treat a clean result as "the layout is right", not as proof of treatment.
