Issuance of Certificate

If approved for recertification, an updated wallet card with the new expiration date will be mailed within 60 days of the date the National Office receives the recertification application. Final receipt of an updated wallet card after recertification will depend upon actual date mailed, the recipient's mailing address, and postal delivery times. Replacements are available for a fee.

As of January 2004, a wall certificate is issued only once. Wall certificates do not have an expiration date and will not be automatically reissued for subsequent recertifications.

Keep Your Information Current

It is the applicant's responsibility to notify the NNCC National Office of any changes in name, address, email, and phone number for the duration of their certification/recertification period. Notifications of changes on other mailing lists such as ANNA may not effect a change in your recertification records.
