To get a bank authorization letter, contact your bank with your government-issued photo ID, your account numbers, and a clear description of what you want the letter to do, then complete the bank’s form either in a branch or through its secure online portal. Most requests are processed within three to seven business days. Before you start, figure out which of the two letters you actually need, because the paperwork and the identity checks differ.
Which Letter Do You Actually Need
Two very different documents go by this name.
An account authorization letter gives a specific person permission to act on your account. The permission can be narrow (viewing balances) or broad (signing checks, initiating wire transfers). Because the bank is changing who can touch your money, the identity verification is heavier.
A bank verification letter, sometimes called a bank comfort letter or bank reference letter, is a statement from the bank confirming details about your account: your name, account type, how long it has been open, and sometimes the current balance. Visa applications, real estate transactions, and prospective business partners are the usual reasons someone asks for one. The bank prints it on official letterhead and you pass it along to whoever requested it.
Pick the right one before you walk into the branch. A banker can produce a verification letter in minutes; adding an authorized signer is a different conversation entirely.
What to Gather Before You Ask
Federal rules require banks to verify the identity of anyone who opens or gains access to a financial account. Under the Customer Identification Program, your bank must collect name, date of birth, address, and an identification number such as a Social Security number or taxpayer ID before giving anyone new access to funds.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks Unexpired government-issued photo ID is required for both you and anyone you’re authorizing.
Have the following ready:
- Your government-issued photo ID (passport or driver’s license) in your current legal name.
- The exact account numbers the authorization should cover.
- The authorized person’s full legal name, address, and date of birth, which the bank will cross-reference against its own identity checks.
- A clear description of what the authorized person can and cannot do: view balances, make withdrawals, sign checks, initiate transfers, or some combination.
Banks usually hand you their own standardized form for adding a signer. Expect a field for the authorized person’s Social Security number; the bank may need it for tax reporting and identity verification. The form is available at the branch or through the bank’s secure online portal.
If the Account Belongs to a Business
Business accounts carry an extra requirement. The bank will almost always ask for a corporate resolution: a formal document showing the board or governing body voted to grant a specific person authority over the company’s accounts. The resolution should name the individual by full legal name and title, describe the transactions they can perform, state the effective date, and be signed by a corporate officer other than the person being authorized. If the corporation has an official seal, affix it. Partnership agreements and LLC operating agreements serve the same purpose. The bank wants proof the entity itself approved the delegation, not just one member of it.
How to Submit the Request
The submission path depends on which letter you need and what your bank allows.
In Person at a Branch
Many banks require the account holder to appear in person to add an authorized signer. The officer witnesses your signature, confirms you’re acting voluntarily, and may ask the authorized person to come in as well to create a signature card and complete identity verification. This wet-ink requirement exists partly for fraud prevention and partly so the bank’s audit trail shows the account holder wasn’t under duress.
A verification letter is simpler in person. You tell the banker what information the recipient needs, and the bank generates the letter on official letterhead. Some branches produce it the same day; others route the request to a back office.
Online or by Phone
Some banks let you start the process through their website or app, though adding a signer online often still requires a follow-up branch visit. Verification letters are easier to request remotely. If your bank’s secure portal has a document request section, you can usually upload supporting documents and complete the request after multi-factor authentication.
When You’ll Need a Notary
Certain authorizations, particularly those involving fiduciary accounts or large delegations of authority, require notarized signatures. The FDIC, for instance, requires notarized affidavits for agency account designations, though a Medallion Signature Guarantee stamp can substitute for notarization in some cases.2FDIC.gov. Affidavits and Declarations in Printable Format Notary fees run roughly $2 to $25 per signature depending on your state. Many branches have a notary on staff who will handle it at no charge for account holders.
Timing and Fees
Once you submit everything, the bank’s compliance team reviews the request. Processing generally takes three to five business days, longer for complex authorizations or business accounts. The bank cross-references the identity information against its records and will follow up if anything doesn’t match.
Official letters usually carry a fee. Amounts vary, but $25 to $50 is common for account verification letters, and some banks waive the fee for premium customers. The finished document is delivered by secure email, by certified mail, or for pickup at the branch.
Define the Scope Carefully
Scope is the one piece of this process that has lasting consequences, and it’s where most people either overthink or underthink the decision. Too broad, and you’ve handed someone the keys to your finances. Too narrow, and the person can’t accomplish what you needed them to do, which sends you back to the bank for new forms.
Common permission levels:
- View-only access: the person can check balances and review statements but cannot move money.
- Transaction authority: the person can make deposits, withdrawals, or transfers, often up to a specified limit.
- Full signatory authority: the person can sign checks, authorize wire transfers, and do essentially anything you could.
Be as specific as the form allows. If you only need someone to deposit checks while you’re traveling, say that and nothing more. The letter should spell out what’s permitted and, where possible, what’s excluded. Ask the bank to include an expiration date if the arrangement is meant to be temporary; without one, the authorization stays in effect indefinitely.
One legal point worth knowing before you decide the scope. Under the Electronic Fund Transfer Act, a transfer initiated by someone you voluntarily gave account access to is generally not treated as “unauthorized,” even if the person goes beyond what you intended.3Office of the Law Revision Counsel. 15 USC 1693a – Definitions If an authorized signer misuses your account, your recourse is against that person directly, not through the bank’s dispute process. Account holders are also responsible for overdrafts and fees an authorized signer runs up; the signer has no ownership obligation to cover losses. Before authorizing anyone, consider whether you’d be comfortable absorbing the worst-case scenario on every account you’re opening up. For business accounts, requiring dual signatures above a certain dollar threshold adds a layer of protection.
If the Bank Refuses
Banks sometimes reject authorization requests, and they frequently resist accepting outside powers of attorney even when the document is perfectly valid. The concern is liability: the bank worries the document has been revoked or the principal has lost capacity since signing it. Many institutions require the agent to sign a certification confirming the principal is alive, hasn’t revoked the document, and that the agent’s authority hasn’t been terminated. Some insist you use their own internal power of attorney form rather than the one your estate planning attorney prepared.
If you’re turned down, ask for the refusal in writing. A missing notarization or an unsigned agent certification is usually a quick fix. If the bank is refusing a valid power of attorney without legal justification, most states have adopted some version of the Uniform Power of Attorney Act, which requires banks to accept valid documents within a set timeframe (often seven business days) or provide a written reason. Banks that refuse without valid justification can face court orders compelling acceptance and liability for your attorney’s fees.
You can also file a complaint with the Consumer Financial Protection Bureau. The online form takes less than 10 minutes, and the CFPB forwards your complaint directly to the bank. Companies generally respond within 15 days, though some cases take up to 60 days for a final response.4Consumer Financial Protection Bureau. Submit a Complaint Include the key facts, dates, and copies of what the bank refused. For a power of attorney dispute, having your attorney contact the bank’s legal department directly often moves things along, since the bank is more comfortable once its own counsel confirms the document meets state requirements.
If you anticipate ever needing someone to manage your bank accounts during a health crisis, completing your bank’s internal power of attorney form in advance, while you’re still healthy, avoids most of these roadblocks.
How to Revoke It Later
Revoking an authorization is simpler than creating one, but you need to do it in writing. Submit a written revocation to your bank in person, by mail, or through the online portal. The Consumer Financial Protection Bureau publishes a sample revocation letter you can adapt as a starting point.5Consumer Financial Protection Bureau.

Removal typically takes three to five business days to process. Keep a copy of your request and any confirmation the bank sends back. Until the bank processes it, the authorized person can still access the account, so if a relationship has deteriorated, timing matters. The primary account holder cannot be removed from the account, since tax reporting is tied to that Social Security number.
