US LLC Documents Explained: What Each Document Does

After a US LLC is set up you hold a small set of records, and it is not always obvious which one answers a given request. A bank asks for formation documents. A payment provider asks for proof of the EIN. Another party asks for a certificate of good standing. These are different documents that come from different places.

They fall into four groups, and the distinction between them is the useful part:

• a filed formation document, prepared by an organizer and filed with and accepted by the state;
• an operating agreement, adopted internally by the members and generally not filed;
• an IRS notice or letter relating to the EIN; and
• a state-issued certificate confirming the entity's status on the state's records at a point in time.

This is general educational information about what these records are, not legal or tax advice for your company.

Quick summary

• The formation document is drafted and signed by an organizer and then filed with the state. The state accepts and records it; it does not write it. The name varies: Delaware uses a certificate of formation, while New York and Wyoming use articles of organization.
• What the filed document contains varies by state. Some states do not collect member information at all, so ownership may need to be evidenced by other records.
• The operating agreement is adopted by the members. New York's Department of State describes it as an internal document that is not filed with the Department.
• EIN confirmation is separate from the EIN application. The IRS currently describes an entity transcript, a CP575 download for eligible Business Tax Account users, and Letter 147C by phone as ways to confirm a previously assigned EIN.
• A certificate of status reflects the state's records on the date of issue. It is not an assurance of overall legal, tax or licensing compliance, or of financial soundness.

The four groups at a glance

Document	Who produces it	What it evidences	When it is used
Filed formation document	Prepared and signed by an organizer; filed with and accepted by the state	That the entity was formed under that state's law, under that name, effective on a stated date	Bank and payment applications, EIN application, counterparty due diligence
Operating agreement	The members, internally	Governance and economic arrangements: management, ownership shares, decision rights, transfers	Where a provider or counterparty asks about governance or ownership; between members
EIN notice or letter	The IRS	That a federal employer identification number is associated with that entity	Bank and payment onboarding, tax filings, EIN verification requests
Certificate of status or good standing	The state of formation	The entity's status on the state's records as at the date of issue	Registering in another state, financing, counterparty or platform checks

The filed formation document

This is the instrument that brings the company into existence under state law.

It is worth being precise about who does what. The document is prepared and signed by an organizer — often the founder, sometimes a formation service acting in that capacity — and submitted to the state. The state examines and accepts the filing and adds it to its records. What you receive back is typically the filed instrument, a certified copy, or an acknowledgement or filing receipt, depending on the state and what you request. The state records the filing rather than authoring the document.

Names differ. Delaware's LLC statute calls it a certificate of formation and requires it to state the company's name, the registered office address, the registered agent's name and address, and any other matters the members choose to include (Delaware Code, Title 6, Chapter 18). New York and Wyoming use the term articles of organization for the equivalent filing (New York Department of State; Wyoming Secretary of State). If a form asks for articles of organization and your state accepted a certificate of formation, it is asking for the same thing.

Formation timing is not always the filing date. Delaware provides that the company is formed when the initial certificate of formation is filed, or at a later date or time specified in the certificate (Delaware Code, Title 6, Chapter 18). If you have chosen a delayed effective date, use it consistently in later applications.

What the filed document contains varies by state. Wyoming's articles of organization form collects the company name, the registered agent's name and physical Wyoming address, the company's mailing address and the principal office address, and does not require members to be listed (Wyoming Secretary of State). Other states collect different fields. Where the filed document does not show who owns the company, ownership is evidenced by other records — an operating agreement, a member register or ledger, issued membership interest records, or similar. That is often why a provider holding your formation document still asks for more.

State law also sets naming rules. Wyoming's instructions cite W.S. 17-29-108 for the requirement that the name include "Limited Liability Company" or a permitted abbreviation such as "LLC" or "L.L.C." Use the name exactly as filed and accepted in later applications. For how the addresses on this document relate to the ones providers ask about, see registered agent vs virtual address vs business address.

The operating agreement

The operating agreement is the members' internal agreement about how the company is governed and how its economics work: management, ownership shares, distributions, admission and exit of members, and how disagreements are resolved.

It is adopted internally rather than filed. New York's Department of State describes the operating agreement as an internal document of the LLC that is not filed with the Department (New York Department of State). It does not appear in a public records search, which is why a provider that needs to see governance or ownership asks you for a copy.

Whether one is required, and in what form, is a question of state law, and states differ:

• New York requires members to adopt a written operating agreement under Section 417 of the Limited Liability Company Law, which may be entered into before, at the time of, or within 90 days after the articles of organization are filed (New York Department of State).
• Delaware defines a limited liability company agreement to include an agreement that is written, oral or implied, provides that it is not subject to any statute of frauds, and confirms that a single-member agreement is enforceable (Delaware Code, Title 6, Chapter 18).

So neither "every LLC must have a written operating agreement" nor "you do not need one" holds generally. Check the law of your formation state.

Beyond the legal minimum, a written agreement gives you something to point to. A bank, payment provider or counterparty may request it when reviewing governance or ownership, and where there is more than one member, recording ownership shares and decision rights in advance is easier than reconstructing them later. Keep the agreement consistent with the legal name on the filed document and with the ownership you report elsewhere.

IRS EIN records

The EIN is the federal employer identification number the IRS assigns to a business (IRS). It is useful to separate two things: applying for the number, and later evidencing it.

Applying. The IRS sets out the available routes and notes that an applicant without a US legal residence or principal place of business applies by phone, fax or mail rather than online (IRS). Applying for an EIN as a non-US resident without an SSN covers how to complete Form SS-4 so the details match your filed formation document.

Evidencing. Institutions usually want a document rather than a typed number. The IRS currently describes three ways to confirm a previously assigned EIN: requesting an entity transcript, downloading a digital CP575 where you are an eligible Business Tax Account user, or calling the business and specialty tax line to request Letter 147C (IRS). The IRS describes the digital CP575 as accepted by banks and other institutions as written confirmation of an entity's EIN, and as usable in place of the original CP575 notice series and Letter 147C (IRS). Business Tax Account access has its own eligibility conditions, so treat the download as one route among three rather than a guaranteed option.

If Shopify cannot verify an EIN, it may request IRS confirmation such as CP575 or Letter 147C. The account’s name and EIN must match the document (Shopify).

Obtaining an EIN does not conclude your federal obligations. A foreign-owned single-member LLC may have an information-reporting duty even where no US income tax is due; see Form 5472 for a foreign-owned US LLC.

The state certificate of status

A certificate of status, called a certificate of good standing in some states, is the state confirming what its own records show about the entity on the date of issue.

Read it for what it is. It reflects the state's records — typically that the entity exists and that required filings and fees are current with that office. It is not an assurance that the company complies with tax, licensing, employment or other obligations, and it says nothing about financial condition.

The form of the certificate varies. Delaware offers a short form, which gives the entity name and its status at the time of issue, and a long form, which additionally lists documents filed with dates and times and any name changes, along with status at the time of issue (Delaware Division of Corporations, retrieved 20 September 2026). Where a certificate is requested, the party requesting it decides which form it needs and how recently it must have been issued, so confirm that before ordering.

Because the certificate reflects current filings, it depends on keeping state obligations up to date. Wyoming's LLC instructions state that annual reports are due each year on the first day of the anniversary month of formation, and that an entity is subject to dissolution if the report is not paid within 60 days of the due date (Wyoming Secretary of State). Requirements and deadlines differ by state.

Supporting records you may be asked for

These are not LLC documents in the strict sense but often form part of the same file. What is requested varies by provider and by jurisdiction:

• Registered agent consent. Wyoming requires a signed consent to appointment to accompany new entity filings, or an online certification that a written consent was received and retained (Wyoming Secretary of State).
• Ownership records. An operating agreement, member register or equivalent, where the filed document does not show members.
• Identity documents for owners and controllers. Which individuals must be identified, and which documents are acceptable, is set by each provider under its own requirements.
• Address evidence. For the business and, depending on the provider, for individuals.
• A description of the business activity, specific enough to answer what the company actually does.
• Annual report or franchise tax confirmations, evidencing the filings behind a status certificate.

These records contain identity and ownership information. Where possible, send them through the institution's own upload channel rather than open email or chat, keep originals and copies somewhere you control, and send the specific document requested.

A document checklist

• The filed formation document as accepted by the state, plus a certified copy or filing acknowledgement if you have one.
• The legal name exactly as filed, and the effective date if it differs from the filing date.
• Registered agent details, and the consent document where the state requires one.
• An operating agreement or other governance record consistent with actual ownership.
• Ownership records, where the filed document does not show members.
• An EIN confirmation document, and awareness of which of the IRS routes is available to you.
• Your addresses recorded by role, each accurate for the field it answers.
• Identity documents for the individuals a given provider requires.
• A written description of the business activity you can use consistently.
• The state's annual filing deadline and fee, in your calendar.

Next steps

If you have not formed yet, sequence matters: choose the state, complete the formation filing, then apply for the EIN using the legal name as accepted by the state, so the records agree from the start.

If you have already formed, review what you hold. Check that the legal name is consistent across your records, that ownership is evidenced somewhere, and that each address field holds an answer appropriate to that field. Where something does not match, correcting it may involve a state amendment, an IRS process or a provider review, so allow time.
