How long do I have to dispute a Citi charge?

Citi's own card agreement requires your billing-error notice in writing, no later than 60 days after Citi sent the first statement showing the error. A phone call alone does not trigger Citi's investigation duty under that agreement — the written letter does.

Can I dispute a pending Citi charge?

No — Citi's dispute flow only offers the dispute option once the charge posts. Walkthroughs of Citi's own dispute-center screens show a reminder option on pending transactions that notifies you when the charge posts; confirm it in your own account, since Citi does not describe it on a public help page.

How do I dispute a Citi debit card charge?

Under federal law (Regulation E), you must report the error within 60 days after the statement was sent — report fraud immediately regardless. File from the posted transaction in your Citi account or call the Customer Service number on the back of your card or on your statement. If the investigation runs past 10 business days, Citi must provisionally credit your account while it continues.

What can I do if Citi denies my dispute?

Use the ladder in order: ask Citi to reconsider in writing with new evidence; if you receive Citi's explanation but still believe your bill is wrong, write within 10 days saying you still refuse to pay, which stops Citi reporting you as delinquent without also reporting that you are questioning the bill; then file a complaint with the CFPB at consumerfinance.gov/complaint, which Citi must answer.

Citi Dispute Navigator — 60-Day Written-Notice Clock

How the math works

The clocks on a Citi dispute, honestly labeled

Citi's own card agreement gives you 60 days from the first statement showing the error, and it must be in writing — every other date in the navigator is labeled by the rulebook it comes from:

Clock	Who sets it	The rule
Citi's 60-day written notice	Citi's own card agreement (citi.com)	"We must hear from you in writing no later than sixty (60) days after we sent you the first statement on which the error or problem appeared" — and a phone call alone does not trigger the investigation duty
FCBA duties after your letter	Federal law, as restated in Citi's agreement	Citi must acknowledge in writing within 30 days and either correct the error or explain why the bill is correct within 90 days
Reg E error notice (debit)	Federal law	Error notice within 60 days after the statement is sent; the bank must investigate within 10 business days (provisional credit if it runs longer)
Network filing window	Card-network norm — not Citi-published	Visa/Mastercard frameworks let the issuer file most dispute categories up to about 120 days from the transaction processing date

How to file with Citi

File online from the posted transaction itself: sign in, open the card account, find the transaction, and choose "Dispute Charge". Then pick the reason from Citi's dispute-center list and answer the follow-up questions. For billing problems, also send the written notice to the billing-inquiries address on the front of your statement by certified mail, and call the Customer Service number on the back of your card or on your statement if you prefer the phone route.

The trap this tool exists to catch

The trap is the phone call: a phone call alone does not require Citi to investigate. Most guides tell you to call Citi and stop there, but Citi's own agreement says only the written notice, within 60 days of the first statement showing the error, triggers the 30-day acknowledgment and 90-day resolution duties. And the 120-day network window is not Citi-published at all — it is the issuer-facing window under card-network rules, which is why a dispute filed through Citi after day 60 can still reach the merchant.

The dispute-center reason list and the pending-charge reminder feature come from walkthrough screenshots of Citi's own screens, labeled as such on this page, because Citi does not publish them on a public help page. Your card agreement is the final word.
