In U.S. banking, DDA usually means demand deposit account, commonly another term for a checking account. The name refers to access to deposited money on demand under the account’s terms. If you saw “DDA” on a statement or account description, the label alone does not tell you the account’s exact fees or withdrawal rules.
What is a demand deposit account?
In everyday consumer language, a DDA is generally a checking account. The Consumer Financial Protection Bureau (CFPB) describes a demand deposit account as “just a different term for a checking account” in its comparison of checking, DDA, and NOW accounts, last reviewed May 2, 2023. CFPB: checking, demand deposit, and NOW accounts.
The word “demand” describes when the depositor may access the funds. Under the Federal Reserve’s Regulation D definition, a demand deposit includes money payable on demand, or money for which the institution does not reserve the right to require at least seven days’ written notice before an intended withdrawal. The definition also includes certain deposits with an original maturity or required notice period of less than seven days. Federal Reserve Regulation D, Section 204.2.
How is a DDA different from a NOW account?
A NOW account is not simply another name for a DDA. Both may function like checking accounts, but the notice right differs: a NOW account may reserve the institution’s right to require at least seven days’ written notice before withdrawal. The CFPB says that right is rarely exercised. Most DDAs, by contrast, allow withdrawals without advance notice; the regulatory category also includes accounts with a notice requirement of six days or less.

The seven-day distinction describes a reserved right and an account classification, not a routine delay that consumers should expect whenever they withdraw money. For context on transaction accounts and deposits, see the Federal Reserve’s explanation of institutions and deposits subject to reserve requirements.
Does having checks mean an account is a DDA?
No. A checkbook by itself does not establish that an account is a demand deposit account. Some money market accounts allow checks, even though they are not generally designed for day-to-day business and may have restrictions. Lenders can also issue checks that draw on a personal loan, home equity loan, or other credit line; those checks access borrowed funds, not money held in a deposit account.

Federal Reserve Regulation CC identifies several types of transaction accounts used for third-party payments or transfers, including demand deposit, NOW, share draft, and automatic transfer accounts. Its definitions help show why check access alone does not identify the underlying account category. Federal Reserve Regulation CC, Section 229.2.

“DDA” is a category label, not a complete description of a bank’s particular product. Check your institution’s account disclosures or contact it to confirm how withdrawals work and what fees or other terms apply. The account’s own terms—not the abbreviation alone—answer those questions.
