CAC PIN locked or forgotten: how to reset it

If you enter the wrong PIN three times in a row, your CAC locks. DoD says there is no way to reset a CAC PIN remotely or online, so no website, app or help desk can do it over the phone.

1. Confirm it's really the PIN

2. Option A: a CPR Trusted Agent in your unit or building

3. Option B: a RAPIDS ID card office

  1. Find a site with the official ID Card Office Online locator (choose "ID Card Office Locator & Appointments"). Some sites take PIN resets as walk-ins; others want an appointment, so check that site's listing or call first.
  2. Bring your CAC. Your identity is checked by matching your fingerprint against the one stored in DEERS. If that may not work, bring two valid forms of ID from DoD's acceptable-documents list (one with a photo).
  3. Have a new 6 to 8 digit PIN ready. Don't use anything easy to guess, such as part of your SSN, a birthday or a phone number.
