Confused about address Texas Service Center

[LeTu]

I am confused about address of Texas Service Center:
1. USCIS Texas Service Center P.O. Box 852135, Mesquite, TX 75185
2. USCIS Texas Service Center 4141 North St. Augustine Road, Dallas, TX 75227

Please let me know which address I should send I-140 and initial documents via USPS priority mail?
Thank you

The instructions have all the information you need. If you are sending with USPS, you can send it to the PO Box. If you are sending it via courier (UPS/FEDEX/etc), the use the other address. This is what the instructions say.
