Store SKU, UPC, model or Internet number: how to identify a Home Depot product
Every Home Depot product carries at least four different numbers. Penny lists are keyed on one of them, receipts print another, the box shows a third and the website uses a fourth. Mixing them up is the most common reason a penny lead goes nowhere, so it is worth knowing exactly which is which.
Store SKU: the one penny lists use
The store SKU is Home Depot's own identifier for a product inside its store systems. It is printed on the shelf tag, and current SKUs are ten digits beginning with 1, usually written in groups of four, three and three: 1004-552-787. Some older products still carry nine-digit SKUs, and a handful of long-running items still show six-digit legacy numbers on the tag.
This is the number to search in the Home Depot app, the number the price scanners and registers resolve to, and the number every penny list, including this one, is built around. If someone posts a find without a store SKU, you cannot reliably look it up.
Two details catch people out. First, every size and every colour is its own SKU. The same Milwaukee work glove in Large and in X-Large has two SKUs, and the black and white versions of the same floodlight camera are two SKUs as well. They are tracked separately, and they can be at completely different stages of clearance in the same store. Second, a product sold both on its own and in a bundle or multi-pack has a separate SKU for each version.
UPC: the barcode, and the number on your receipt
The UPC is the manufacturer's barcode printed on the package. In North America it is usually twelve digits. Imported products sometimes carry a thirteen-digit EAN instead, which starts with a country prefix; a gas fire pit made overseas, for example, may show a barcode beginning with 69 rather than the 0 or 7 you see on most domestic goods.
When you check out, the register scans the barcode, and the receipt prints the barcode number next to a compressed, upper-case description. That is why a receipt photo almost never shows the store SKU. A Ryobi LINK organizer shelf comes out on a receipt as a run of letters like RYBLNKORGSHF beside its UPC, and the SKU appears nowhere. It is also why a receipt and a shelf tag can show two completely unrelated numbers for the same product.
Model number: useful, but easy to misread
The model number is the manufacturer's part number, printed on the box and in the product title online. It is the best number to search when you want specifications or a manual, and it is how you confirm you are holding the right product in the aisle.
It is a poor number to hunt by, though. Model numbers in the same product family often differ by a single character, and the same model can be sold under more than one SKU. Drill bit sets and accessory kits are the usual trouble spots. Two Milwaukee SHOCKWAVE bit sets we checked this autumn had model numbers that differed only in the last digit, 48-20-9050 and 48-20-9058, and from a photo of the box they were easy to confuse. Only the barcode settled which one had been bought.
Internet number: for the website only
The Internet number is the nine-digit identifier homedepot.com uses at the end of a product address, as in /p/product-name/315741165. It is handy for pulling up the official listing and product photo, but it means nothing inside the store and you will not find it on a shelf tag or a receipt.
Turning a receipt into a SKU
- Search the barcode on homedepot.com or in the app. Typing the full UPC into the search box usually jumps straight to the product page. The page lists the Internet number, model number and store SKU just under the product title.
- Check size, colour and pack count. If the receipt description mentions a size, a colour code or a pack count, make sure the listing you landed on matches. A search can land on the nearest variant rather than the exact one.
- If the search finds nothing, the product may be delisted. That is common for items at the end of their markdown. Search the model number instead, or search the UPC on the wider web: manufacturer pages and other retailers' listings usually show the barcode, and that will at least confirm the product and its model.
- Treat a SKU without a source as a guess. If a post gives a SKU and the receipt in the same post points to a different product, trust the receipt.
Mistakes we see every week
- A slice of a UPC posted as a SKU. A ten-digit number that starts with 0 or 7 is almost certainly part of a barcode, because current Home Depot store SKUs start with 1.
- The right product, the wrong variant. A different size, colour or pack count, each with its own SKU and its own markdown schedule.
- A SKU attached to the wrong product. In September a SKU was posted for an 18 ft multi-position ladder that actually belonged to a 4 ft podium ladder. The barcode on a finder's receipt led to the right 18 ft SKU.
- Transposed digits. Always worth a second look when a SKU returns nothing.
How Penny Recon handles it
When an item reaches the list from a receipt or a shelf photo, its SKU is matched to the product listing, by the barcode wherever the receipt shows one, and the name, model number, photo and Internet number come from that listing rather than from the post. When the posted SKU and the receipt disagree, the receipt wins. Items that cannot be identified at all are held back from the site until they can. More on the method is on the About page.
