If your e-signature card or device is lost or stolen, or you suspect that someone else knows your PIN, contact E-İmzaTR without delay. Do not assume that PIN protection alone is sufficient. Request the appropriate suspension or revocation procedure for your certificate.

What should I do first?

• Report the loss, theft or suspected unauthorised use promptly.
• Follow E-İmzaTR's instructions to suspend or revoke your certificate.
• Confirm that the procedure has been completed and check your certificate's current status.

Visit the Suspension and Revocation page in Turkish for the available channels. If you cannot complete the online procedure because your device is missing, contact E-İmzaTR's revocation hotline directly. Do not wait to find the device or complete a software installation.

Is changing my PIN enough?

If the security of your device or signature creation data is in doubt, changing the PIN alone should not be treated as sufficient. Report the incident to E-İmzaTR and follow the instructions for your certificate.

Is a blocked PIN the same as a revoked certificate?

No. A PIN block concerns access to the device. Certificate suspension or revocation concerns the certificate's validity status. A blocked PIN does not mean that the certificate has been revoked.

Can I use the device if I find it later?

Finding the device does not automatically make the certificate usable again. Confirm its status with E-İmzaTR before resuming use. Do not continue signing with a revoked certificate.

How can I protect my e-signature?

• Do not share your card, device or PIN.
• Do not keep the PIN with the device.
• Review the document and transaction details before signing.
• Do not sign at the request of an unknown person.
