Bank Authorization Letter Template for the United States

What is a Bank Authorization Letter?

Bank Authorization Letters are essential documents in U.S. banking operations, used when an account holder needs to delegate banking authority to other individuals or entities. The letter serves as official documentation that enables designated parties to perform specific banking transactions, access account information, or manage accounts on the holder's behalf. A properly drafted Bank Authorization Letter must include clear identification of all parties involved, specific permissions granted, and comply with federal banking regulations and state laws. It's particularly crucial for businesses, organizations, and individuals who need to authorize others to handle their banking matters while maintaining proper documentation and security protocols.

About the Bank Authorization Letter

A bank authorization letter is a written instruction from an account holder that grants a named individual or entity permission to conduct specific banking transactions on the account. It gives the bank a documented basis to accept actions from someone other than the account holder while keeping control in the account holder's hands. Under United States federal banking law, the letter should support the identification and anti-money laundering controls set out in the Bank Secrecy Act and USA PATRIOT Act.

What should a bank authorization letter include?

A complete letter leaves no room for a bank to reject it or for the authorized person to overstep. Include the following details:

• Account holder details: full legal name, address, and contact information of the person granting authority.
• Account information: the account number and account type (checking, savings, or business).
• Authorized party details: full legal name and identification details of the person or entity receiving permission.
• Scope of authority: the exact transactions allowed, such as deposits, withdrawals, wire transfers, or read-only access to balances and statements.
• Limits: any dollar caps, per-transaction limits, or accounts the authorization does not cover.
• Effective and expiration dates: when the authority starts and ends.
• Revocation terms: how the account holder can cancel the authorization.
• Signature and date: the account holder's signature, with notarization or a witness where the bank requires it.

What does a bank authorization letter look like?

Here is a short worked example for a personal checking account that limits the authorized person to deposits and inquiries only:

Date: March 3, 2025. To: The Branch Manager, First National Bank, 220 Market Street. Re: Authorization on Checking Account No. 0000-123456. I, Maria Delgado, account holder of the above account, authorize James Park (Driver's License No. D1234567) to deposit funds into and view the balance and statements of this account on my behalf. This authorization does not permit withdrawals, wire transfers, or any movement of funds out of the account. It is effective from March 3, 2025 and expires on September 3, 2025, unless revoked earlier in writing. Signed, Maria Delgado.

Each line maps to one of the required elements above: the parties, the account, the exact scope, the limits, the dates, and the signature. Swap in your own details and adjust the scope to match what you actually want the authorized person to do.

When do you need this document?

You'll need a bank authorization letter when you cannot personally handle your banking matters but require someone else to act on your behalf. Common situations include business operations where employees need account access, elderly individuals who need family members to manage finances, or travelers who need representatives to handle urgent banking matters. The document is also useful for corporate accounts where multiple authorized signatories are required for different types of transactions.

How do you write a bank authorization letter?

Start with the date and the bank's name and branch address, then address the letter to the bank manager or the accounts department. In the opening line, state that you are authorizing a named person to act on your account and give the account number. Next, describe precisely what the authorized person can and cannot do, then set the start and end dates. Close with your signature and, if your bank asks for it, a notary block or witness line. Before you sign, log in to your online banking or call the branch to confirm any bank-specific forms or formatting the institution requires, since some banks ask you to complete their own authorization form rather than accept a general template. Once the details are set, you can draft, edit, and download a ready-to-use version for free.

Read-only access versus full transaction authority

Match the scope to the need. A read-only authorization lets the named person view balances, statements, and transaction history without moving any money, which suits an accountant, bookkeeper, or family member who only needs visibility. Full transaction authority lets the person deposit, withdraw, and wire funds, so it carries more risk and usually draws closer identity checks from the bank. Many account holders start narrow and expand later, since you can issue a new letter or revoke and replace the old one at any time. For a business account, you can also name different signatories for different transaction types, for example read-only access for one person and wire authority capped at a set dollar amount for another.

Can I give permission for someone to access my bank account?

Yes. A bank authorization letter is one way to give another person permission to access your account, and you can limit that access to specific actions such as viewing balances, making deposits, or handling a single transaction. You stay the account holder, so you remain responsible for authorized activity, and you can revoke permission at any time. For read-only needs, restrict the letter to inquiries only rather than the ability to move funds. Keep in mind that some banks also require the authorized person to appear in branch and present identification before they will honor the letter.

How do you revoke a bank authorization letter?

To cancel the authority, send the bank a written revocation that names the account, the authorized person, and the original letter, and states the effective date the permission ends. Keep a copy for your records and ask the bank to confirm the change in writing. Because you can revoke access this way, it's worth setting a clear expiration date in the original letter so authority does not continue longer than you intend.

Key legal considerations

Your authorization letter must clearly define the scope of authority being granted to avoid unauthorized actions and potential liability. Under the Electronic Funds Transfer Act and Federal Reserve Regulation E, you remain ultimately responsible for all authorized transactions. The document should specify whether the authorized party can make withdrawals, deposits, wire transfers, or simply access account information. Duration clauses matter, so set clear expiration dates and include provisions for immediate revocation if needed. Please also make sure the authorized party understands the bank's customer identification requirements under the USA PATRIOT Act before they try to use the letter.

Legal requirements in United States

Federal banking regulations require your authorization letter to include specific elements for validity. Under the Bank Secrecy Act, banks must maintain detailed records of authorized representatives, so your document must contain complete identification information for all parties. The USA PATRIOT Act mandates enhanced customer identification procedures, meaning authorized parties may need to provide additional documentation before banks will honor the authorization. UCC Article 4A governs wire transfer authorizations, requiring specific language for wholesale wire transfer authority. Your bank may have additional internal policies requiring notarization, witness signatures, or a particular format. Always verify your bank's requirements before finalizing the document, as some institutions require their own authorization forms rather than accepting general templates.

Bank authorization letter versus a power of attorney

A bank authorization letter covers specific, named transactions on a specific account, and the account holder keeps direct control. A power of attorney grants broader legal authority over financial affairs and usually needs to meet state-law formalities such as notarization. For most routine banking tasks, where you want a colleague, relative, or representative to handle defined actions on one account, the authorization letter is the lighter, faster instrument. If you need wider authority than one account and a fixed list of transactions, a power of attorney is the more appropriate route.
