Grainger Order and Delivery Help
Customers can check an order using Grainger’s Order Lookup. The lookup form requests the order number and the email address used to place the order. Registered customers can also sign in to review their order history.
For a missing, incomplete, delayed, or damaged shipment, contact Grainger with the order number, item numbers, delivery address, and tracking details. Retain the shipping carton, labels, packing material, and damaged merchandise until Grainger or the carrier provides instructions.
Grainger Returns, Refunds, and Warranty Assistance
Grainger’s official Product Return Policy generally provides a 30-day satisfaction guarantee when proof of purchase is available, unless an exception applies. Certain unused and saleable products may remain eligible after 30 days, but conditions, restocking charges, or other restrictions may apply.
Sourced products, custom products, special orders, emergency-response items, and merchandise identified as final sale or nonreturnable may be excluded. Contact Grainger Customer Care at 1-800-472-4643 before shipping a return. Customers outside the U.S. can call 608-755-6560 for return assistance.
Have the purchase date, invoice number, item number, reason for return, and requested resolution ready. Do not send merchandise to Grainger’s corporate headquarters unless a representative specifically instructs you to do so.
Grainger Branch and After-Hours Access
Grainger branches can assist with pickup, product questions, returns, invoicing, and other service needs. Because branch schedules vary, check the official branch locator before visiting.
Grainger also advertises after-hours branch access through 1-800-225-5994 (1-800-CALL-WWG). Availability varies by location, a Grainger account may be required, and a fee may apply.
