Got it:

The AKC Rules Applying to Dog Shows (Chapter 11, Section 1) allow you to show in AKC events using a dog's foreign registration number if that registration is with an acceptable foreign registry. Please note that dog cannot be shown on a foreign litter number. The dog must be individually registered with the foreign registry.

The dog may compete for thirty days beginning with the first day of exhibit. When completing an Official AKC Entry Form for an event, the dog's foreign registration number should be recorded in the appropriate space on the form indicating the country of origin.

After thirty days, either one of these two things must happen for the dog to be shown:

1. The AKC registration must be recorded and the dog must be shown using its individual AKC registration number, or
2. You must have been granted an extension to continue showing with the foreign number. Requests for extensions must be in writing (by mail, fax, or email) and must have been granted prior to the event.

The "Request for Extension" form with a letter of notification is automatically sent out after the first time that you show a dog on a non-AKC registration number in an AKC event. This form can be mailed to the address on the form or faxed to 919-816-4220. Requests must also include a copy of the dog's foreign registration. The actual request form is not needed for an extension request. A written request can also be mailed to AKC, Attn: Show Operations, 8051 Arco Corporate Drive, Suite 100, Raleigh, NC 27617-3390, or faxed to 919-816-4220. On the request, the dog's foreign number, name, and breed must be listed along with the owner's name, address, and phone number. The request must also include a brief explanation for the delay in registration and a copy of the dog's foreign registration.

There is a Non-Refundable fee of $50.00 for a 90 days extension. If your extension request is granted, you will be sent a letter of confirmation by regular mail within 7 to 10 days. This letter will tell you the length of the extension. You will be able to show your dog under the foreign number for the duration of the extension.

To register a foreign-registered dog with the AKC, you need to obtain the AKC Foreign Registration Application form. The form can be downloaded from our web site. Complete instructions are on the form.

For general information about extensions, you can contact our Special Services Department at awards@akc.org. If you have questions related to foreign registration you can address those to foreign@akc.org.

Good info - sounds similar to the ERN numbers that the CKC uses.
