PO Box Format

[???? ???? ???? ????]

We are finding cases where street address and PO Box we use the following format per USPS guidelines:

Jane Doe
1200 Main St
PO Box 500
Sauk City WI 53583

The Accuzip file switching the formatting from the example above to the example below:

Jane Doe
PO Box 500
1200 Main St
Sauk City WI 53583

Can you confirm the process for AccuZip to format these types of addresses? Thanks.
