NFS4,
That is the basic format, but there are variances based on region. For example, here are what the numbers would look like if it came from me.
1z 650e5w 0140 xxxxxx
Next Day Air
1z 650e5w 0240 xxxxxx
Second Day Air
1z 650e5w 0340 xxxxxx
Ground
There are also variations based on whether an adult signature is required and other special handling considerations, as well as whether it is Saver, Early AM, etc.
