The correct spelling is B-A-N-K
Bank is spelled with four letters: B, then A, then N, then K. It refers to a financial institution that holds money in accounts, processes payments, and lends money to borrowers. The word comes from the Italian word "banca," which originally meant a bench or counter where money changers worked.
The spelling is consistent across English-speaking countries — the United States, United Kingdom, Canada, and Australia all use the same four letters. You will see it spelled this way on your statements, on your debit card, and in any official banking document.
If you are writing a check, filling out a form, or setting up online banking, use this spelling. Misspelling it as "banck" or "bnak" will cause confusion and may delay processing, especially on official documents.

Common related banking terms and how to spell them
Banking (B-A-N-K-I-N-G) is the noun form describing the business or activity of working with a bank. You might say "I use online banking" or "She works in banking." The I and G are added to the root word "bank" following standard English rules.
Banker (B-A-N-K-E-R) is a person who works at a bank or manages banking operations. A banker might help you open an account or discuss a loan. The E and R are added to "bank" to create the job title.
Bankrupt (B-A-N-K-R-U-P-T) means legally unable to pay debts. It comes from the same root as "bank" but has a different ending. The word is often used in the phrase "file for bankruptcy," which is the legal process of declaring you cannot pay what you owe.
Bankroll (B-A-N-K-R-O-L-L) means money set aside to fund something, or to provide money for a project. You might hear "He bankrolled the startup" or "The team's bankroll for the season." This word combines "bank" with "roll," an older term for a sum of money.
Why spelling matters on banking documents
Banks process thousands of transactions daily using automated systems that read names, account numbers, and institution names. If you misspell "bank" on a check or wire transfer form, the system may not recognize the receiving institution, and your payment could be delayed or rejected.
On a check, the bank name appears in the lower left corner and in the routing number section. The routing number itself is a nine-digit code that identifies the specific bank branch, so spelling the bank name correctly on the memo line or in a letter ensures the payment reaches the right place.
When setting up bill pay or a wire transfer online, you will type the receiving bank's name into a form. Misspelling it might cause the system to flag the transaction for review or ask you to confirm the institution before processing.
How to find the correct spelling of your bank's name
The most reliable source is your own bank statement or debit card. The official name appears exactly as the institution wants it spelled — sometimes with abbreviations, sometimes with a location, sometimes with a full legal name that differs from how you think of it.
Your bank's website will also show the official spelling in the footer, on the login page, or in the "Contact Us" section. If you are unsure, call the bank's customer service line and ask them to spell the name for you. They hear this question regularly and can confirm whether it is "Bank of America" or "BankAmerica," or whether your regional bank uses an ampersand or spells out "and."
For wire transfers or ACH payments to another bank, the receiving bank's name should match exactly what appears in the Federal Reserve's routing number database. You can search for a bank's routing number and official name on the Federal Reserve's website or through your own bank's wire transfer form.
Common spelling mistakes to avoid
The most frequent error is doubling the K — writing "bankk" instead of "bank." This happens because people sometimes double the final consonant when adding a suffix, but "bank" does not follow that rule. You write "banking," not "banking," and "banker," not "bancker."
Another mistake is confusing "bank" with "blank," which is spelled B-L-A-N-K and means empty. A blank check is one with no amount filled in. A bank is the institution. The words sound similar but have completely different meanings and spellings.
Some people write "banc" (missing the K) when abbreviating, especially in older or informal contexts. This is not standard modern English and should not appear on official documents. Always use the full spelling "bank" on anything formal.
Frequently Asked Questions
Is it "bank" or "banque" in English?
"Banque" is the French spelling. In English, the correct spelling is always "bank." If you are reading a document in French or dealing with a French financial institution, you may see "banque," but in English-language banking, use "bank."
Do I need to capitalize "bank" when I write it?
Capitalize "bank" only when it is part of a proper name, such as "Chase Bank" or "Bank of America." In a sentence like "I went to the bank today," the word is lowercase. Check your bank statement to see whether the institution capitalizes it in their official name.
What if my bank's name has unusual spelling or punctuation?
Use the spelling and punctuation exactly as the bank shows it on their official documents and website. Some banks use ampersands (&), hyphens, or abbreviations. Match it precisely when filling out forms or writing checks to avoid processing delays.
Is "banking" spelled with one N or two?
Banking is spelled with one N: B-A-N-K-I-N-G. You add the suffix "-ing" to the root word "bank" without doubling the final consonant. The same rule applies to "banker" and "banked."
