I will speak for my situation with regards to the fraudulent OFA I was given by my breeder.
And please note, OFA's and pedigrees will not necessarily be "colored" as they are photocopied many times to be put into puppy packets.
So the OFA on my puppy's sire reads:
RO-61818G28F-NOPI
So what is wrong with this number? Well let's break it down and understand what it means:
RO - stands for breed, in this case, Rottweiler
61818 - stands for the number of Rottweilers issued a number
G - stands for the hip rating of the dog, in this case "Good"
28 - stands for the age of the dog in months
F - stands for the sex of the dog, in this case
FEMALE!!! 
NOPI - stands for "not permanently identified" (no tattoos or micro chips)
Here is the lesson to be learned...
KNOW WHAT YOU ARE READING!!!! This is where I made my mistake.
This OFA belongs to one of her bitches who had a "good" rating. The stud (my puppy's sire) did not have a passing OFA so she just whited out the female's name and typed in the stud dog's name and made copies.
The paperwork means nothing if you don't know how to read it.
