Changes to Registration Numbers and Event Submission Requirements

CKC has updated its dog registration numbering system as of November 1st, 2019.
With the exception of dogs registered as Canadian Born, all dogs registered after November 1st will receive a 12-character registration number. This number will include a prefix consisting of a two-letter abbreviation of the registration type, a hyphen, and the standard 9-character registration number (two letters followed by 7 digits).
Examples:        Event Registration Number: EN-AB1234567
                         Miscellaneous Certification Number:  MN-AB1234567
                         Performance Event Number: PN-AB1234567
                         Canine Companion Number: CN-AB1234567
The entire number, including prefixes, must be used on all applications and when entering events. The entire number must also be submitted with all event results. Other prefixes not listed above include AK, AN, NR and FD for various CKC recognized breeds.
Dogs registered before November 1st, 2019 will maintain their current registration number, and will enter events using this number as written on their registration documents. The new 12-character registration number only affects dogs registered after November 1st, 2019.
Note: Dog’s registered as Canadian Born Dogs WILL NOT have a two-letter abbreviation or hyphen in their registration number.
Canadian Born Dog Registration numbers will remain as previously issued.
