It seems to simple, here's the first.
MODIFICATION (folding/crumpling) of race numbers and placement of race numbers
1) Don't fold your number down. That makes it REALLY, REALLY difficult to read, even when using a 5,000 frames per second camera.
2) Let's define a "crumpled" number. One that gets folds in it while in your bag or maybe you sit on it, that may not cause it to be unreadable. But, taking the number and wadding it up over and over again so that it's ragged, yes, that makes it tough to read. Don't believe me, at the next race sit next to Jim Karnes while he tries to read race numbers.
Here's the official USAC rule:
1N7. Racing numbers.
(a) Racing number are provided by the organizer, who may require a deposit that shall be refunded on return of the numbers in good order. The figures shall not be hand written, but printed in block letters using black waterproof ink. Numbers shall be constructed from materials sufficiently durable to last the race without tearing or disintegrating, even in adverse weather. The name of the race or race sponsor may appear on a competitor's number. Promoters who fail to provide numbers meeting the above requirements to all riders shall be fined as specified in the Schedule of Fees.
(b) Riders shall place their numbers as prescribed by the officials and in such a way that they are visible when the rider is in a racing position. When shoulder numbers are provided for cyclocross, they are worn on the upper arm to be visible from the front. Hip numbers shall be attached securely at least at the four corners with pins and no accessory or hair may obstruct a clear view of the number (riders with misplaced, obscured or unreadable numbers will not be placed). If shoulder or frame numbers are provided, they too shall be placed as prescribed. Numbers may not be folded, trimmed, crumpled, or otherwise defaced. [Replacement of the numbers at riders' expense if noted before the start, otherwise warning or relegation.]
Wanna hear all sides, read Steve Tilfords post on the subject and the many comments that follow:

I like this one common-sensical comment:
Is it always a real issue? No. Can it be? Yes. The fact that Steve Tilford is always scored is because you are Steve Tilford. Can it be hard to score riders that the official doesn’t know? Yes. Does the crumpled number make it even harder? Sometimes, yes
Wanna do it right (pin your number)? read this article:

Want to see exactly what I'm talking about? Take a look at this image, the Pro I/II finish from Frankenmuth, May 29, 2010. Try to read the numbers of the top 10 finishers. Post up the numbers.
You may need to download the image to your computer and then view it using a picture viewer, etc for better effect.
