How Does Overnight Shipping Work
Posted On 2nd October 2025When you order something, whether it’s from an online shop, directly from a retailer, or through another person, it often gets shipped overnight. If you’ve been involved in some kind of logistics before, you have probably wondered how does overnight shipping works.
The first thing to know is that it’s much more complex when compared to day shipping.
Overnight deliveries are mainly used for anything that falls under the category “time-sensitive shipment”, and they require thoughtful timing and good organization to be executed smoothly.
This quick guide will unwrap everything for you, including exactly what overnight shipping is, who can handle it, what the cost is, and how overnight shipping vs next day shipping compare.
What Is Overnight Shipping

So, to explain what does overnight shipping means as concisely as possible, we can just call it a “promise” that something sent today is guaranteed to arrive tomorrow. This means the very next business day, which makes the overnight shipping service one of the most frequently used ways to deal with anything that needs to be hauled quickly.
However, the actual overnight shipping meaning can be different based on exact location, the zip codes, and, of course, the shipping zones. While the idea remains the same, the precise delivery times still depend on distance, cut-off times, and exactly when the shipment has been submitted by the sender.
That’s why some freight shipping carriers provide several different delivery options within their overnight delivery services, which range based on the time of submission. Also, if you’re wondering, is overnight shipping really overnight – yes, in most cases it is.
How Fast is Overnight Shipping
Most, if not all, overnight shipment services guarantee the arrival of the shipped items within 24 hours after submission. In that case, “within” means on the same day, before the cutoff times. In some large cities or when the shipping zones are closer to each other, you can see the absolute fastest overnight shipping available.
Who Does Overnight Shipping
If you’re wondering exactly who does overnight shipping in towns and cities, well, that would be the major carriers. Many shipping companies have overnight shipping options, but the pricing is definitely different when compared to the daytime delivery service.
To better understand where you can find overnight shipping, here are some examples:
- National delivery providers are typically the best overnight shipping companies, which are separated into three submission segments – early morning, mid-day, and end-of-day.
- Many regional carriers also specialize in overnight deliveries, but in most cases, they are restricted to zip codes and shipping zones, handling only short route transportation.
- A lot of postal services also provide overnight shipping options, which are wallet-friendly and guaranteed next-day delivery, but only for lower weights.
- Many third-party logistics companies offer overnight shipping options, commonly working with e-commerce online stores for urgent deliveries.
Note: There are even more carriers, typically working with companies to fulfill warehousing by shipping overnight.
How Long Does Overnight Shipping Take
So, we’ve learned how long does overnight shipping takes (within 24 hours), but how the time of the submission actually influences the delivery pipeline. Well, while the promise says “next day”, the only way to know when the goods are supposed to arrive is by the time you hand them in.
The exact time always comes down to the shipping zones, cutoff times, and how quickly the shipping service can transport the items.
The general rule here is that the earlier you submit the package, the sooner it will arrive, and the carriers design the delivery option based on specific windows.
Here’s what you expect, based on when you hand in the items:
- Early: If you send the items early in the morning, let’s say at around 8–9 AM, the quickest overnight shipping would be 8 AM to 10:30 AM the next day.
- Mid-day: If you hand in the package at around noon, the overnight delivery service will schedule it in a way so that it can arrive before noon the next business day.
- End-of-day: If you submit the shipment and the end of the working day, the package will surely use the best way to ship overnight, arriving in the early evening.
What Is Cheapest Overnight Shipping
When it comes to overnight shipping options, cost is one of the biggest concerns that people have, but it’s understandable for such an urgent service.
If you’re wondering what is the cheapest overnight shipping, this depends on the weight, route, shipping zones, and, of course, the nature of your shipment.
To help you estimate the cost of your overnight delivery service, here are a few examples:
Example: | Weight: | Distance: | Estimated Cost | Delivery Window |
Documents | 1 lb | Local (Zone 2–3) | $25 – $35 | By 10:30 AM, next business day |
Medium Box | 5 lbs | Regional (Zone 4–5) | $40 – $55 | Mid-day next day |
Large Parcel | 10 lbs | National (Zone 7–8) | $70 – $90 | End-of-day next day |
20+ lbs | $120 – $150+ | The next day evening | ||
Flat-Rate Envelope | Up to 70 lbs | Nationwide | $28 – $40 | Guaranteed day delivery next day |
For instance, FedEx offers overnight shipping!
Note: Please be informed that the prices in the table are purely an example, even though they are based on actual shipping service ranges. Hence, the real price you might have to pay could vary from what’s shown above, based on different factors.
What Is Next Day Shipping
Now that we have a basic understanding of what overnight shipping is, many people are wondering what next-day shipping is and whether it’s any different.
Well, while both services have a guaranteed next-day delivery, overnight shipping is much more strict with the 24-hour rule, even though in both cases, we’re speaking about a delivery that arrives the next day.
At its core, it means when you ship the next day, the package arrives on the following business day. The way this shipping works is by estimating when your package was submitted, and it must be before specific cutoff times, so it can move through the pipeline efficiently.
Many next-day shipping services also offer options like Saturday delivery and even provide overnight shipping for any time-sensitive goods.
Overnight Shipping vs Next Day Shipping - Is there a Difference?
We understand that it’s quite easy to get lost and mix both terms here, but in practice, overnight delivery services and ship next day are closely related. So, in reality, the only thing setting them apart is your specific requirements, and which shipping option can assist you more efficiently.
- Overnight Shipping: The overnight shipping simply refers to a promise given by the carrier that the package left today will arrive on the very next business day. So, if you’re wondering how do you overnight a package, this would be the service for you.
- Next Day Shipping: The next day shipping is practically the same, but is more standardized and mainly covers day delivery guarantees. The next day delivery cost is quite lower, but here (most likely) there won’t be an actual overnight routing.
So, the main difference is in branding, cost, and flexibility!
Some carriers offer premium upgrades for the fastest shipping service, while the others simply bundle it under their offers overnight programs. If you’re looking for the best overnight shipping service, the choice comes down to speed and what is cheaper in overnight shipping for you.
