'''Price look-up codes''', commonly called '''PLU codes''', '''PLU numbers''', '''PLUs''', '''produce codes''', or '''produce labels''', are a system of numbers that uniquely identify bulk [[produce]] sold in [[grocery store]]s and [[supermarket]]s. The codes have been in use since 1990, and over 1400 have been assigned.<ref name="PLU FAQ" /> The codes are administered by the [[International Federation for Produce Standards]] (IFPS), a global coalition of fruit and vegetable associations that was formed in 2001 to introduce PLU numbers globally.<ref>{{cite web|title=About IFPS: Who Are We?|url=http://www.ifpsglobal.com/AboutIFPS.aspx|publisher=IFPS|access-date=24 September 2015|quote=IFPS is composed of national produce associations from around the globe.|archive-url=https://web.archive.org/web/20150310160444/http://www.ifpsglobal.com/AboutIFPS.aspx|archive-date=10 March 2015 }}</ref>

Produce labeled with PLU codes eliminates the need for grocery store checkers and customers to visually identify different varieties, which can make check-out and [[inventory control]] easier, faster, and more accurate, something that is important when varieties of produce look similar, but have different prices, such as organic and conventional (non-organic) varieties.

==Uses==
PLU codes are used primarily in retail grocery stores or supermarkets, where they are keyed into [[point of sale]] systems by [[cashier]]s or by [[customer]]s at [[self-checkout]] machines when the produce is being weighed or counted. The codes may be printed on small stickers, tags, or bands that are affixed to produce, or may be printed on signs. Since 2006, stickers with PLU codes may also have a [[GS1 DataBar Coupon|GS1 DataBar Stacked Omnidirectional]] barcode.<ref>{{cite web|url=http://www.pma.com/content/articles/2014/05/gs1-databar|title=GS1 DataBar|access-date=8 August 2015}}</ref>

==Numbering conventions==

Conventional produce is randomly assigned four-digit PLU codes in the 3000 and 4000 series.<ref name="PLU FAQ">{{Cite web

Numbers 83000-84999 were supposed to be used for GMO productions, but they were opened for general use after GMO growers declined to use them.<ref name="PLU FAQ" />

===Retailer-assigned codes===
Some PLU code ranges are reserved for retailers. This allows codes to be defined by individual retailers or location, and allows the use of PLU codes in lieu of barcodes. There are retailer-assigned ranges for general and category-specific use. For example, 3170–3269 can be assigned by retailers to any goods, while 4193–4217 can only be assigned to apples.{{Citation needed|date=January 2022}}

Suppliers may coordinate with their retailers to use the same code in the retailer-assigned range for a specific product.{{Citation needed|date=January 2022}}

==Promotion via PLU stickers==
Some producers have obtained a license to place characters on stickers on PLU code labels, often as a [[promotion (marketing)|promotion]] for a movie, television show or other media franchise. For example, Imagination Farms has marketed produce with collectible [[The Walt Disney Company|Disney]] character stickers such as [[Toy Story]] and [[Finding Nemo]] under the [[Disney Garden]] brand,<ref>[http://www.thepacker.com/fruit-vegetable-news/imagination_farms_announces_disney_branding_effort_122100574.html Imagination Farms announces Disney branding effort]. ''The Packer''. 17 May 2011</ref> and [[Chiquita]] has marketed bananas with [[Minions (film)|Minions]] stickers on them, along with a competition.<ref>Heather Fletcher.

== Collecting ==
Although the collecting of PLU labels as a hobby already existed for a while, it became widespread through social media presence and fashion designs that use fruit stickers. The popularity of the hobby was further increased by online catalogs and collector clubs.<ref>{{Cite web|url=https://colnect.com/fruit_stickers|title=Fruit Stickers on Colnect|website=colnect.com |access-date=2018-12-27}}</ref>

In addition to illustrations, important factors for collectors are compositions of these stickers and the type of product they are used on. Most popular materials for creating PLU code stickers are plastic film and paper, however cardboard, metallized film, wrapping tissue, and textiles are also known to be used.{{Citation needed|date=January 2022}}

== Environmental concerns ==
Although PLU labels are recognized globally and most chain supermarkets use them, they sometimes cause rejection of the fruits and vegetables to which they are attached from being accepted for composting disposal or disposal by [[cruise ship]]s at sea. Generally, they are not made of biodegradable material.<ref>{{Cite news |title=How Produce Stickers Contribute to Climate Change |work=[[CBC.ca|CBC]] |url=https://www.cbc.ca/news/technology/what-on-earth-newsletter-fruit-stickers-climate-change-1.5462794 |date=4 February 2020 |first=Emily |last=Chung |access-date=2021-01-22 }}</ref>
