The Purpose for PLU Codes
A PMA volunteer committee developed worth lookup codes again in 1988. One vital purpose for PLUs was to allow supermarkets to inform the distinction between conventionally grown vegetables and fruit and higher-priced natural meals.
"Natural produce was being launched by retailers then and so they had been paying a premium for natural, and their cashiers had been promoting it on the standard worth," Treacy says. "A conventionally grown fruit or vegetable seems to be the identical as an natural fruit or vegetable."
To unravel that downside, the trade got here up with a system by which conventionally grown produce gadgets are assigned four-digit numbers within the 3000 and 4000 vary. If a fruit or vegetable is raised organically, it will get a prefix of 9 positioned in entrance of the standard code for that merchandise, in line with an article on the PMA web site. The PMA provides that the codes "usually are not meant to convey data to customers. They’re merely enterprise instruments for correct worth rings on the money register, stock management and class administration." Additionally, the numbers inside these four-digit codes are randomly assigned.
