A CHGDDA charge on your bank statement is not a company or merchant. It’s an internal bank code that stands for “charge to demand deposit account,” meaning money was debited from your checking account.1NatWest. Do You Have a List of Statement Abbreviations2Consumer Financial Protection Bureau. What Is the Difference Between a Checking Account, a Demand Deposit Account, and a NOW Account The label describes the mechanics — a charge hit a checking account — but says nothing about who was paid or why.
Breaking the Code Down
“CHG” is a common banking abbreviation for “charge.”1NatWest. Do You Have a List of Statement Abbreviations “DDA” stands for “demand deposit account,” the industry term for a checking account — an account from which you can withdraw funds at any time without notice.3Investopedia. Demand Deposit Account Concatenated, CHGDDA just tells you a debit posted to your checking account. The underlying transaction could be almost anything: a monthly maintenance fee, an overdraft fee, an automatic bill payment, a point-of-sale debit, or an ACH withdrawal.
Some banking platforms display extra detail — a merchant name, a reference number, a date — next to the code. Others show the abbreviation alone. That is why a legitimate fee or purchase can still look suspicious: the label describes what kind of movement occurred, not the source.
How to Identify the Actual Charge
If the CHGDDA entry does not match anything you remember authorizing, call your bank’s customer service line and ask them to identify it. Representatives can pull the underlying transaction detail — the merchant or payee name, the authorization date, and the amount — even when the statement line hides it. Have your account number and the date of the charge in front of you when you call.
If the bank’s answer matches a purchase or automatic payment you made, you’re done. If it doesn’t, or the bank confirms the debit wasn’t authorized, the next step is a formal dispute.
Disputing a CHGDDA Charge on a Checking Account
Debits from a checking account, including those posted through a debit card or ACH, are covered by the Electronic Fund Transfer Act and Regulation E. You may report an error by phone or in writing, but the bank can require a follow-up written notice within 10 business days of a phone report. The bank must investigate promptly. If the investigation runs longer than 10 business days, it generally must provisionally credit the disputed amount to your account while it finishes. The full investigation must conclude within 45 days.4Minnesota Attorney General. Dispute Credit Charges
If the charge actually hit a credit card rather than your checking account, a different law applies. The Fair Credit Billing Act requires a written billing-error notice to the card issuer’s billing-inquiry address within 60 days after the statement containing the error was mailed.5FTC. Using Credit Cards and Disputing Charges A phone call alone will not preserve your rights on the credit-card side.
Why Reporting Fast Matters
Liability caps for unauthorized debit-card use tighten quickly with time. Reporting within two business days of discovering the unauthorized activity limits your liability to $50. Reporting after two business days but within 60 days of the statement being sent raises the cap to $500. Waiting more than 60 days can expose you to unlimited liability for unauthorized transactions that occur after that window closes.4Minnesota Attorney General. Dispute Credit Charges
Credit-card liability works differently and is capped at $50 by federal law, an amount many issuers waive. If you report the card lost or stolen before any unauthorized charge posts, your liability is zero. If only the number was used and you still have the card, you generally owe nothing either.6Consumer Financial Protection Bureau.

Where to Escalate If the Bank Won’t Fix It
If the bank refuses to reverse an unauthorized CHGDDA debit or doesn’t resolve the investigation in your favor, federal agencies accept complaints.
- The Consumer Financial Protection Bureau takes complaints at consumerfinance.gov/complaint or (855) 411-2372. The CFPB forwards the complaint to the bank, which typically responds within 15 days.7Consumer Financial Protection Bureau. Submit a Complaint
- The Federal Trade Commission handles fraud and identity theft reports at IdentityTheft.gov, where the site generates a recovery plan and sample letters.8FTC. Report Identity Theft
- The Office of the Comptroller of the Currency oversees national banks and federal savings associations, and advises contacting the card issuer right away, placing a fraud alert with the credit bureaus, and filing a report with local law enforcement.9OCC. Credit Card and Debit Card Fraud
Your state attorney general’s office is another route for banking complaints and can often help push a stalled dispute forward.
