Business banking applications may request an EIN, owner information, identity documents, deposits, personal credit, or a guarantee depending on the institution. Compare current requirements rather than relying on a universal EIN-only rule.
This pillar post walks the four-section arc every Town Mayor Financial client runs before walking into an application. Section one sets up why the EIN is the bank’s master key, not your SSN — and what an anchored EIN file actually looks like. Section two names the five EIN-only-friendly banks, framed as the recommendation set. Section three lists exactly what to bring to the application — EIN letter, articles, beneficial-owner ID, flow projection, domain. Section four closes with the week-one moves that turn a fresh account into a tradeline-carrying file. Read it end to end, or jump to the section that matches where your entity is right now.
Why your EIN is the bank account’s master key, not your SSN
Banks key off the EIN file thickness, not your SSN. When you walk into a business banking application, the underwriter opens Experian Business, Dun & Bradstreet, and Equifax Business against the EIN — not against your name. A thick file (bank anchor present, vendor trade lines reporting, NAICS code aligned) gets you to the no-personal-guarantee tier without a single dollar in the account. A thin file gets you the SSN-required-with-personal-guarantee tier that you wanted to avoid in the first place.
The thing founders miss is that without an EIN letter (CP 575), articles of incorporation, and a tax-id-as-business-id mental model, the bank has nothing to anchor to. It falls back to your SSN, your personal credit score, and your personal checking history. The bank is not being unreasonable — it just has no file on the entity yet. Pull the EIN first. Anchor it to a real bank account second. Then the rest of the file — vendor trade lines, Paydex, business credit — builds itself.

Questions to ask before choosing a business bank
Provider terms change. Ask each institution about entity age, owner verification, deposits, personal-credit review, guarantees, fees, reporting, and account eligibility. A business account does not guarantee later credit approval.
The reason the list is five and not three is the same reason the post is four sections. Every founder arrives at a different EIN file thickness. A brand-new entity with no revenue can walk into Relay or North One and walk out with an account that afternoon. An entity with $10K of monthly flow and a domain pointing to a real operating site can walk into Bluevine and open a sweep account. An entity in the API/SaaS bracket gets Mercury on the same evidence. The graph is not flat — it is fit-tested, and your place on it depends on file thickness, flow bracket, and industry code. Pick the bank that matches your tier, apply once, and the account opens.
A guide to reviewing an EIN, business bank account, and vendor-reporting plan. Personal credit, guarantees, cash, revenue, and other requirements vary by provider.
What to bring to the application
Five documents and one flow projection. Document one: the EIN letter (IRS form CP 575) — not a screenshot, the actual letter. Document two: articles of incorporation or operating agreement, depending on entity type. Document three: beneficial-owner government ID, one per owner of twenty-five percent or more. Document four: the entity’s domain or website. Document five: any existing contracts, even draft ones, that show inbound flow. The flow projection is a one-page document listing expected monthly deposits, expected monthly outflows, and the source of the inflow — vendor payments, customer invoices, capital loans. Banks want to see where the money comes from before they will sweep a balance to interest.
The order matters. Pull the EIN letter before you book the application — most rejections come from a missing CP 575, not from an unreadable file. Have the articles bound and the owner IDs in hand before walking in. Walk in with the flow projection, not after — it is the bank underwriter’s first question. And do not skip the domain. A live website or a registered domain proves the entity is real in a way an SSN never will. The whole application is about painting a real entity for the underwriter: nine-digit tax id, real documents, real flow, real domain. That is enough.
Twenty minutes, free, no obligation. We walk your EIN file against the five-bank recommendation set and tell you which one matches your tier, what to bring to the application, and how the week-one tradeline-onboarding moves would look for your entity. If you are not ready for any of them, we will tell you which pillar to finish first.
What to do the week the account lands
A bank account is not a finish line — it is the start of the file build. The week the account lands, two things happen. First, the account gets the first ACH in and the first ACH out — both for small, real amounts, not test transfers, not vanity inflows. Second, the first vendor gets connected on net-30. Vendor one is Uline. Vendor two is Quill. Vendor three is Grainger. Open them in that order, pay them like clockwork, and the file starts compounding a Paydex in the 70s to low 80s inside two reporting cycles.
The cadence is what keeps the file there. Pay every net-30 vendor inside of twenty-five days, not thirty. Never float a balance past the due date once. Never close the first revolving account after six months. After one full quarter of clean payments — three on-time vendor reports, two quarters of clean bank statements — graduate the file into the lender graph. The graduation step is Lendavo: read the now-thick EIN file against the closing-history of the lenders in our network, and surface the ordered list of products that close for a profile in your tier. The bank account was the anchor. Lendavo is the conversion of the anchor into capital. The patience matters more than the speed.
