Using ZBar to scan VIN barcodes adds extra "I" character

Question

I am using ZBar iOS SDK to scan VIN barcodes on an app. But it sometimes adds an extra "I" character in front of the VIN and omits the last character.

Also, I am using CODE 39 symbology. Is that correct or will I have to change it?

The leading "I" stands for Import and is only coded into some VIN barcodes. See this discussion thread for more details:

As for the symbology, VIN barcodes come in a variety of formats, such as Code 39, Code 128, or PDF Matrix.

What you find out of thread pointed by Gambit is: Remove the I in the beginning if the scanned number is more than 17 characters(number of characters in a VIN)
