The Manufacturer file is sorted alphanumerically, which means that the Manufacturer ID 10AHOP would be placed ahead of AHOP10. Also, keep in mind that a 5-character Manufacturer ID could be placed before a 3-character Manufacturer ID.

 

This is a list of Manufacturer IDs, as they would be placed in the Manufacturer file:

 

10PPD  -  AP1  -  BFRB10  -  ZRB10  -  ZRB100
