A bank letterhead is the preprinted header on a bank’s official stationery, carrying the institution’s name, logo, address, phone number, and website. It’s what turns a printed page into a document that landlords, lenders, courts, and government agencies will accept as coming from your bank. You get a document on bank letterhead by asking a branch to issue one, or by downloading an official statement or letter through your online banking portal.
What Appears on Official Bank Stationery
The header identifies the institution at a glance. Expect to see the bank’s legal name, its registered logo, a corporate or branch address, a verified telephone number, and the official website. Together these give a recipient a way to confirm that the document actually came from the bank named on it.
Some letterhead carries additional identifiers used in financial networks. The SWIFT code appears on documents tied to international wire transfers, and the nine-digit ABA routing number identifies the bank in domestic ACH and wire payments.1American Bankers Association. ABA Routing Number Many banks include “Member FDIC” or the FDIC symbol on their stationery by choice; federal rules requiring the advertising statement apply mainly to advertisements for deposit products, not general correspondence.2eCFR. 12 CFR Part 328 – FDIC Official Signs, Advertisement of Membership The Equal Housing Lender symbol turns up on some letterhead for the same reason, though the regulation actually requires it as a lobby poster rather than on letters.3eCFR. 12 CFR 128.5 – Equal Housing Lender Poster
Documents Banks Issue on Letterhead
A few document types come up over and over in ordinary financial life:
- Account verification letters confirming you hold an account and, often, its current balance or history. Landlords, government agencies, and lenders ask for these routinely.
- Proof of funds letters confirming you have enough liquid assets to complete a purchase. Common in real estate transactions.
- Credit reference letters summarizing your borrowing and payment history for a third-party creditor.
- Monthly and periodic statements. Your regular statements already carry the bank’s branding and are accepted as supporting records for tax filings, court proceedings, and mortgage underwriting.
Because these documents reflect the bank’s own records, the letterhead effectively turns a printed page into a verified financial record. Mortgage underwriters read statements to confirm consistent income and asset levels before approving a loan, and third parties treat letterhead as a threshold sign that the information came from an accountable, regulated source.
How to Request a Document on Bank Letterhead
The most direct route is to walk into a branch and ask a banker or branch manager. You can request account verification letters, proof of funds letters, or certified copies of statements. Many banks charge for these; verification of deposit requests at major banks commonly run $15 to $25, though some categories (such as requests from government agencies) may be free. Fees vary, so ask before placing the order.
If you’d rather not visit a branch, most banks let you download official statements and letters as PDFs through the secure online portal. These files retain the letterhead and are generally accepted by third parties. When a recipient wants a cleaner chain of custody, such as during a real estate closing or a legal proceeding, ask the bank to mail or fax a certified copy directly to that third party so the document never passes through your hands.
When Letterhead Isn’t Enough: Medallion Signature Guarantees
Some transactions, especially transferring or selling securities, require more than a letter. A medallion signature guarantee is a special stamp from a bank employee confirming your signature is genuine, and unlike a standard notarization, the bank itself accepts liability for any forgery. Only banks and financial institutions that participate in a recognized medallion program can provide one, and they typically require you to be an existing customer.
How to Tell if a Bank Letter Is Genuine
If you’re on the receiving end of a bank letter, whether from a tenant, buyer, or borrower, the format itself carries clues. Watch for:
- Inconsistent fonts within the same document, which suggest sections were added or altered later.
- A blurry, pixelated, or off-color logo, which may have been copied from a website rather than printed from an official template.
- Missing or unverifiable contact details. A legitimate letter includes a phone number and address that actually reach the bank.
- Math errors, or figures that look manually adjusted.
- A routing number that doesn’t match the named bank, or an account number with the wrong number of digits.
The most reliable check is to call the bank directly using a phone number you look up independently, not one printed on the document in front of you. Ask the bank to confirm the letter was issued and that its contents match their records. Many banks will verify documents by phone or through a secure portal once the account holder has authorized the inquiry.
Digital documents deserve the same caution. Banks increasingly issue letters and statements as PDFs through online portals, and legitimate files often carry digital signatures that use encryption to show the document hasn’t been altered since it was created. Some also embed timestamped audit trails. If a bank letter reaches you electronically from a third party rather than from the bank’s own portal, ask the bank to confirm it before relying on it.
Fabricating or altering a bank’s letterhead is federal bank fraud, punishable by a fine of up to $1,000,000, a prison term of up to 30 years, or both.4Office of the Law Revision Counsel. 18 USC 1344 – Bank Fraud Submitting a forged bank letter to influence a loan or credit decision falls under a separate federal statute carrying the same maximum penalties.5Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally
How Long to Keep Bank Documents
Once you have official bank records, the IRS expects you to keep anything that supports income, deductions, or credits on your tax return until the limitations period expires. For most filers, that means at least three years from the date you filed. The window stretches to six years if you underreport gross income by more than 25 percent, and there is no time limit if you never file or file a fraudulent return.6Internal Revenue Service. How Long Should I Keep Records
Keep supporting records for seven years if you claim a loss from worthless securities or a bad debt deduction. Employment tax records should stay on file for at least four years after the tax becomes due or is paid, whichever is later.6Internal Revenue Service. How Long Should I Keep Records On the bank’s side, financial institutions must retain transaction records for five years under anti-money laundering rules, so your bank can often reproduce documents within that window if you lose your copies.7eCFR. 31 CFR 1010.430 – Nature of Records and Retention Period
