What postal code should I use for billing and shipping addresses in Baton Rouge?
Use the specific nine-digit ZIP code for your street address, which is usually the first five digits, such as 70801 for many central locations, followed by the four-digit suffix assigned to your delivery point.
Will my package be delivered if I only put 70801 as the postal code Baton Rouge without the full address?
While 70801 helps route your package to the general area, you still need the full street address and apartment or suite number to ensure timely and accurate delivery.
