How the math works
The clocks on a Navy Federal dispute, honestly labeled
The single most important fact about Navy Federal disputes is a negative one: Navy Federal's own FAQ pages publish no filing deadline. What they publish is a resolution promise. Everything else that looks like a deadline comes from federal law or from the card networks — and the navigator labels which is which, because they answer different questions:
| Clock | Who sets it | The rule |
|---|
| Navy Federal resolution window | Navy Federal's own published rule | "Resolution will occur within 2 complete billing cycles (but no more than 90 days) from the date you notify us" — navyfederal.org, Credit Cards FAQs |
| FCBA written notice (credit) | Federal law | Written billing-error notice within 60 days of the first bill showing the error; creditor must acknowledge in writing within 30 days and resolve within two billing cycles |
| 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 Navy-Federal-published | Visa/Mastercard frameworks let the issuer file most dispute categories up to about 120 days from the transaction processing date |
The form split that decides whether your case stalls
Navy Federal runs billing disputes and fraud claims through different forms and different mailboxes. Filing under the wrong one slows your case down:
| Your case | Form (Navy Federal's own name) | Mail to |
|---|
| Debit billing dispute | Statement of Dispute | Debit Card Services, PO Box 23603, Merrifield, VA 22119-3603 |
| Debit fraud | Statement of Forgery | Navy Federal Credit Union, Attn: Card Fraud Prevention Recovery, PO Box 3503, Merrifield, VA 22119-3503 |
| Credit billing dispute | By mail to Credit Card Disputes | Navy Federal Credit Union, Attention: Credit Card Disputes, PO Box 3503, Merrifield, VA 22119-3503 |
| Credit fraud | Written Statement of Forgery for Credit Card | Navy Federal Credit Union, Attn: Credit Card Recovery, PO Box 3503, Merrifield, VA 22119-3503 |

GO Prepaid — for unauthorized transactions, call 1-855-477-1138.
You do not have to pay while it is investigated
Navy Federal's own FAQ states it plainly: you are not responsible to pay the disputed amount or the associated interest charges during the investigation. The catch to plan around: your available credit will be reduced by the disputed amount unless a temporary or permanent credit has been given. If the investigation finds no error occurred, you will be responsible for paying the disputed transaction.
What Navy Federal will not accept as evidence
Navy Federal cannot use videos, voice recordings or printed pictures to support your claim. You can provide phone records to show attempts to contact the merchant. Send documents by secure document upload through the Navy Federal Case Status Center (the preferred method), by secure message in online banking, by mail to the mailbox above, or at a branch.
