I think there is some confusion for some sellers about using their EIN from their LLC for Etsy. You should only use your EIN from your LLC IF you have also filed the proper form with the IRS to be treated as a corporation. Most LLC's are still considered sole proprietors. Here is some documentation directly from the IRS that talks about using your SSN or personal EIN for information reporting purposes (which is 1099 speak). Hope this helps --
A Limited Liability Company (LLC) is an entity created by state statute. Depending on elections made by the LLC and the number of members, the IRS will treat an LLC either as a corporation, partnership, or as part of the owner's tax return (a "disregarded entity"). A domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and elects to be treated as a corporation. For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and affirmatively elects to be treated as a corporation. However, for purposes of employment tax and certain excise taxes, an LLC with only one member is still considered a separate entity.
Owner of Single-Member LLC
If a single-member LLC does not elect to be treated as a corporation, the LLC is a "disregarded entity," and the LLC's activities should be reflected on its owner's federal tax return. If the owner is an individual, the activities of the LLC will generally be reflected on:
An individual owner of a single-member LLC that operates a trade or business is subject to the tax on net earnings from self employment in the same manner as a sole proprietorship.
If the single-member LLC is owned by a corporation or partnership, the LLC should be reflected on its owner's federal tax return as a division of the corporation or partnership.
Taxpayer Identification Number
For federal income tax purposes, a single-member LLC classified as a disregarded entity generally must use the owner's social security number (SSN) or employer identification number (EIN) for all information returns and reporting related to income tax. For example, if a disregarded entity LLC that is owned by an individual is required to provide a Form W-9, Request for Taxpayer Identification Number (TIN) and Certification, the W-9 should provide the owner’s SSN or EIN, not the LLC’s EIN.
