That would depend.
If you are shipping a variety of items to an end user which is dependent on their order, no GTIN is required for such a shipping case per FDA UDI Rule. Instead you would include a packing slip or other transportation documentation regarding contents of the shipment.
GTINs are Global trade Item Numbers should be assigned to each fixed packaging level intended to be sent to another company.
To fulfill the spirit of the preamble to the FDA UDI Rule, you would want to have the UDI-DI+PI on every level of packaging so that the item can be traced to the point of use.
GTINs are typically assigned up to the highest shipping quantity that can be ordered by a customer which can vary; case, gaylord or pallet level.
Regarding placmeent of the GTIN carrier, GS1 US has a number of documents available free in their resource library.
From Guidelines for Bar Code Symbol Placement Revised May 2007 (c) GS1 US
7.1
General Rule
The bar codes on units intended for general distribution should be upright (in picket fence orientation) and placed on the sides of the unit. Each item should have at least one bar code and two are recommended when these are preprinted.
7.1.2 Symbol Placement on Cartons and Outer Cases
For cartons and outer cases, symbol placement will vary slightly in practice, however the target placement for the bottom of the bar code symbol is 32 mm (1.25 inches) from the natural base of the item. The symbol including its quiet Zones should be at least 19 mm (0.75 inches) from any vertical edge to avoid damage.
