Home Depot assigns several different numbers to the same product, and the one you need depends entirely on what you are trying to do with it. A Store SKU will not work on a web order. An Internet number will not appear on a store purchase order. This guide covers each identifier Home Depot uses, where to find it, which one belongs on your documents, and how to map them so orders resolve correctly no matter which number arrives.

What Are the Different Home Depot Product Numbers?
Home Depot runs separate systems for stores and for HomeDepot.com, and each assigns its own identifier. A product sold through both carries numbers from both, plus whatever your own catalog and the manufacturer already assigned. Five identifiers commonly appear against a single item.
| Identifier | Looks like | What it identifies |
|---|---|---|
| Store SKU | 1007730316 | The item number Home Depot's retail system uses to track inventory in stores. Typically 9 or 10 digits, numeric only. |
| Internet Number | 320243591 | The identifier used on HomeDepot.com for search and customer support. Shown on the product page. |
| OMSID | Assigned by Home Depot | Order Management System Identification Number. The online item ID, separate from any in-store SKU, assigned once an item submission is approved in the vendor portal. |
| Store SO SKU | 1007727796 | Special Order SKU, used for items not stocked in store but available for order or custom delivery. |
| Model Number | NXT1A06 | The manufacturer's own product code. Alphanumeric, set by the brand rather than by Home Depot. |
Your own SKU and the UPC or GTIN sit alongside these. That gives seven possible numbers for one physical item on one shelf, which is why identifier mapping is the single most common source of setup errors for new Home Depot suppliers.
Where Do I Look Up a Home Depot SKU?
The right source depends on which number you need.
- Store SKU, Internet number, and Model number. All three appear on the public HomeDepot.com product page for the item, usually grouped near the product title or in the specifications section.
- OMSID. Available in the Home Depot vendor portal once your item submission has been approved. It is not published on the public product page.
- SKUs for your own catalog. Home Depot supplies these in the product data file sent to you. The numbers are numeric and usually 9 or 10 digits, for example 324589791.
- Store SO SKU. Appears on the product page for special order items alongside the standard Store SKU.
If you are searching HomeDepot.com and getting no results for a number, the most common cause is searching a Store SKU on the web catalog, or a UPC that Home Depot has not indexed for site search. Both are expected behavior rather than a data problem on your side.
Which Number Goes on a Purchase Order, ASN, or Invoice?
Home Depot sends the identifier it expects back. The rule that avoids almost every rejection is simple: return exactly what arrived on the inbound document, and do not substitute a number your own system prefers.
| Document | What to send back |
|---|---|
| 850 purchase order in | Home Depot identifies each line with their own SKU. Record it against your item rather than overwriting your SKU with it. |
| 855 acknowledgement out | Echo the Home Depot SKU exactly as received, with your own vendor part number in its own qualifier if required. |
| 856 advance ship notice out | Home Depot SKU per line, matched to actual carton contents rather than to the original order quantity. |
| 810 invoice out | Home Depot SKU per line, matched to what shipped on the ASN rather than what was ordered. |
Mismatches between the ASN and the invoice are one of the more expensive errors to make, because the deduction usually costs more than the line was worth.
How Do I Map Home Depot Numbers to My Own SKUs?
The durable answer is to keep your own SKU as the master record and attach every Home Depot identifier to it as an alternate, rather than renaming your items to match a retailer. Do that once and an order arriving against any of those numbers resolves to the same physical item, with inventory counts staying correct across every channel you sell on.
InfiPlex stores the Home Depot SKU against your item as thehomedepot_sku. To load them in bulk, build a CSV with two columns and upload it through the SKU Utilities tool using Set Identifying Data:
sku,thehomedepot_sku ABC-1001,324589791 ABC-1002,324589804 ABC-1003,324589817
The same tool sets ASIN, GTIN, UPC, ISBN, and barcode values, so every retailer and marketplace identifier for an item lives in one place. Full steps are in the Home Depot SKU Set-up guide.
Once mapped, purchase orders from Home Depot arrive as ordinary orders in InfiPlex, matched to your own SKU, with acknowledgements, ASNs, and invoices generated and returned automatically. Your warehouse team picks against the number on your shelf, and Home Depot receives the number their system expects.
Are Home Depot Canada SKUs Different?
Yes. Home Depot Canada runs its own item catalog, so the same product carries a different SKU there than it does in the United States. A number that resolves on HomeDepot.com will frequently return nothing on HomeDepot.ca. If you supply both, treat them as two separate identifiers mapped to the same master SKU rather than assuming one number covers both.
Selling to Home Depot Without Managing This by Hand
Identifier mapping is the visible half of supplying Home Depot. The other half is EDI: purchase orders, acknowledgements inside their window, advance ship notices built from real carton contents, and invoices matched to what actually shipped.
InfiPlex handles both. Home Depot connects as a managed EDI integration, so there is no EDI software to license and no translation to maintain, and Home Depot orders sit alongside Amazon, Walmart, Lowe's, Costco, and every other channel in one system with one inventory pool. Pricing starts at $49.99 a month and is published in full, support is USA based, and most connections go live in days.

Home Depot SKU Questions
What does a Home Depot SKU number look like?
Home Depot Store SKUs are numeric and usually 9 or 10 digits, for example 324589791 or 1007730316. They contain no letters. An alphanumeric code like NXT1A06 is the manufacturer's model number rather than a Home Depot SKU.
What is the difference between a Home Depot SKU and an Internet number?
The Store SKU is the number Home Depot's retail system uses to track inventory in physical stores. The Internet number identifies the item on HomeDepot.com for search and customer support. The same product commonly has both, and they are not interchangeable.
What is an OMSID at Home Depot?
OMSID stands for Order Management System Identification Number. It is the online item identifier Home Depot assigns once your item submission is approved in the vendor portal, and it is separate from any in-store SKU the item carries.
Where do I find the Home Depot SKU for my own products?
Home Depot provides them in the product data file sent to suppliers. Store SKUs and Internet numbers for items already listed also appear on the public HomeDepot.com product page. OMSIDs are only available through the vendor portal.
Can one product have more than one Home Depot SKU?
Yes. A product can carry a Store SKU, a Store SO SKU for special order fulfillment, an Internet number, and an OMSID at the same time. Mapping all of them to one master SKU in your own system is what keeps inventory counts accurate.
Do I need EDI to sell to Home Depot?
Home Depot requires EDI for purchase orders and the documents that follow them. You do not need to run EDI software yourself. InfiPlex connects Home Depot as a managed EDI integration and delivers their purchase orders as ordinary orders, generating acknowledgements, ASNs, and invoices automatically.
