The LG rebate form requires you to fill out your contact information, product serial numbers, and requires you to sign and date at the bottom.
For your reference, the sections of an example rebate form are illustrated below:
The annotated sections correspond to the locations on our
example invoice diagram.
Your product serial numbers are
required to complete the form. Do not mail the form without filling out
all of your appliance's serial numbers in the spaces provided. It is normal to have some fields left over that correspond to products that you did not purchase, but ensure that
every applicable product you purchased is represented on the form. Missing product serial numbers will result in rejection of your rebate.

Ensure that you have filled out all of the fields on the rebate form including your full contact information as it appears on your invoice, product serial numbers, and do not forget to sign and date at the bottom. Incomplete rebate forms will be rejected by the rebate provider.

The address you fill out must match the address printed on your invoice, either the "Bill To" (C) or "Ship To" (D) addresses. Do not use any other address. Do not use a PO box address. Mismatched, incomplete, or incorrect addresses will result in rejection or non-payment.
Fill out a copy of your actual rebate form, of the program appropriate for your purchase and product. Do not attempt to mail the example form on your screen. The example on your screen is not an exact copy of the appropriate rebate form and may represent and expired program or a different program than is appropriate for your product.
