What is the initiative?

HEB Grocery will be requiring their suppliers to send the 855 (Purchase Order Acknowledgement) and 856 (Advance Shipment Notice) EDI transactions. There are specific instructions depending on what kind of supplier you are. Please be sure to read this article in its entirety.

Is HEB changing anything?

HEB will be switching the UPC numbers from 13 digits to 14 digits.

Is Testing required?

HEB is NOT requiring testing of these transactions. Check out the details below regarding these transactions. If you've never sent these transactions before or if you have any questions, please contact TrueCommerce.

Prior to sending these transactions, make sure they are in Production mode. Check out this article for steps on how to do this.

What is the 855 (Purchase Order Acknowledgement)?

The EDI 855 is used to acknowledge that a Purchase Order was received. This transaction can be created by Turnaround.


Pharmaceutical suppliers are NOT required to send the 855.

What is the 856 (Advance Shipment Notice)?

The EDI 856 is used to alert a buyer that a shipment has been processed and is on its way. This transaction can be created by Turnaround.

You'll want to select the ASN structure that matches the physical shipment:

Pick and Pack (SOPI) - Use if you're shipping boxes/cartons.


Pallet Pick and Pack New (SOTPI) - Use if you're shipping on pallets.


Pharmaceutical customers will need to utilize the DSCSA ASNs.

If you're receiving a Grocery Product Purchase Order (875), the expiration date is mandatory on the 856.
