Greetings @Seller_q2V9ODC1aTSYL,

For oversized deliveries, you'll want to use a freight shipping template as it allows you to properly schedule delivery with your buyer via one of two methods:

Arranged Freight Delivery

• This option requires you, or your carrier, to contact the customer via phone or Buyer-Seller Messaging within 2 business days of the order being placed, to set up a delivery appointment time. At checkout, customers are notified that they will be contacted to arrange the date of the delivery, and are given an option to update their phone number. This is the default shipping option, and will always be enabled for products listed on the freight-shipping template. Note that all calls to customers should happen between 8am - 8pm based on the customer’s local time zone.

Scheduled Delivery

• The customer will see the available delivery slots, and will have the option to pick any available slot at their convenience. You can use Seller Central to offer either day or day and time slots during which you or your carrier can deliver. This is an optional shipping method for freight templates, and you will have the choice to enable this ship option alongside Arranged Freight Delivery. If the customer selects Scheduled Delivery, you are not required to contact them post-order. All Scheduled Delivery orders will have a “Scheduled Delivery” message displayed on the Manage Orders page along with the date of delivery.

Based on Amazon's communication guidelines, I would not recommend requesting the buyer's phone number for this delivery and would keep all communications within Buyer-Seller messaging.
