ACA (American Cat Assoc) pedigree numbers?

Hi, I'm looking at a new CFA certified pedigree (Siamese). In the 5th generation (most cats from the 1970's) there are two cats listed that have non CFA numbers. I have been able to determine they are ACA numbers. Does anyone know how to determine the cats color from ACA numbers? Is there a reference page you can point me to that would help me decode the numbers?

Thank you for your help, again.

Sorry but I only showed/registered CFA and ACFA. I'm assuming the color of the cats is not listed under the number - just the number?

You might try looking up the association on the web and seeing if you can find the registration numbers and the coding

That was the first thing I did. I can only find mention of an address for the ACA. I was hoping a member here might know.

Thank you for answering

I would give them a call and ask about the numbers.
