Ground Advantage Delivery Time (USPS)
Ground Advantage is the USPS ground service for packages up to 70 pounds, and USPS expects 2 to 5 days. Which of those it is depends on the route.
Across the 814,506 routes between 3-digit ZIP areas in the lower 48 states, 9.8% are 2-day, 33.8% are 3-day, 38.5% are 4-day and 18.0% are 5-day. Enter two ZIP codes to see yours.

How long does USPS Ground Advantage take?
USPS Ground Advantage takes 2 to 5 days in the lower 48 states, and the exact figure for your route is set by USPS for each pair of 3-digit ZIP areas.
Most routes are 3 or 4 days.
The 2-day routes are short hops inside a region; about 85% of the 5-day routes start or end in one of the 11 western states, from Washington and California to Colorado and New Mexico.
These are the shares in the USPS Service Standards Directory of October 1, 2026, counting each of the 814,506 lower-48 routes once:
- 2 days: 9.8% of routes
- 3 days: 33.8% of routes
- 4 days: 38.5% of routes
- 5 days: 18.0% of routes
- Average: 3.65 days
So "2 to 5 days" is true, and it is also not very useful on its own: the chance that your package is on a 2-day route is about 1 in 10. Look up the pair. The days count from the day you hand the package in before the Post Office's cutoff, and they are a service standard, not a guarantee.
What is the latest day to send Ground Advantage?
Know when it has to arrive? Enter the date and get the latest drop-off day, counted back from the days USPS publishes for your ZIP pair.
The day it must be delivered.
How long does Ground Advantage take in the same state?
Inside one state, Ground Advantage is 2 days on 53.6% of routes and 3 days on 43.4%.
Only 3.0% of the 23,972 in-state routes carry a 4-day standard, and no in-state route is 5 days.
The 4-day ones are in the long or thinly served states: Texas end to end has the most, then Kentucky, Arkansas, Nebraska and Kansas.
If your package stays in the state and it has not arrived 3 days after USPS accepted it, check your pair in the calculator: most in-state routes are 2 or 3 days, but 3% are 4.
How does USPS count the days?
Day 0 is the day the package enters the network before the cutoff, and USPS counts Sundays as transit days, except (since April 1, 2025) the Sunday right after a Saturday mailing (a package entered the day before a holiday may skip Sundays too). Holidays never count.
USPS's expected dates for Ground Advantage never fall on a Sunday or holiday, so a count that lands on one moves to the next delivery day. A package dropped off on a Sunday or holiday starts the next day USPS accepts mail.
A 3-day package mailed on Thursday is due Monday. The same package mailed on Saturday is due Wednesday, because that Sunday does not count.
The calculator applies that rule.
In our check of September 26, 2026 its dates matched all 3,051 answers we saved from USPS's own Service Commitments tool (21,357 date checks), leaving out routes to or from Guam and Saipan, 4 Post Offices that send mail out the next morning, and Holy Cross, Alaska.
For some remote Alaska Post Offices, such as Bethel, Sitka and Holy Cross, USPS's tool gives First-Class Mail, Ground Advantage and Media Mail more days than its published directory, so allow extra time there.
Is Priority Mail faster than Ground Advantage?
Priority Mail is faster on paper on 56.5% of lower-48 routes and has the same day count on 43.5%. Where it is faster, it is faster by one day on 33.3% of routes, by two days on 20.0% and by three days on 3.2%. Priority Mail is always 2 or 3 days; Ground Advantage runs 2 to 5.
So the extra money buys the most on long routes, where Ground Advantage is 5 days and Priority Mail is 3.
On a short route both are 2 days and Priority Mail buys little more than the free boxes and Flat Rate pricing; both include $100 of insurance. Run both ZIPs in the calculator; it shows the two side by side.
Choose Ground Advantage when
- The two services show the same days for your pair
- The package can wait until the standard says it arrives
- It is heavy and does not fit a Flat Rate box
- It is a return or a low-value item
Choose Priority Mail when
- Your pair is a 4- or 5-day Ground Advantage route
- The buyer expects it in 2 or 3 days
- You want a Flat Rate box for a heavy item
Is a Ground Advantage package faster than a First-Class letter?
Yes, on 35.1% of lower-48 routes a Ground Advantage package has a shorter standard than a First-Class Mail letter, and on 64.7% the two are equal. The letter is faster on 0.1% of routes.
That surprises people, but it follows from the standards: letters run 2 to 5 days with 32.2% of routes at 5, packages run 2 to 5 with 18.0% at 5.
If you are choosing between sending a padded envelope as a First-Class large envelope and as a package, the package is tracked and insured, and on all but about 1,000 of 814,506 lower-48 routes it is no slower on paper.
Does the weight change the delivery time?
No. USPS publishes one standard for packages under 16 ounces and one for 16 ounces to 70 pounds, and in the current directory (October 1, 2026) the two are identical on every route, Alaska, Hawaii and the territories included.
Weight changes the price: under 16 ounces the price steps up at 4, 8, 12 and 15.999 ounces, then by the pound. It does not change the days in the lower 48.
Which ZIP codes get an extra day on Ground Advantage?
10,562 origin ZIP codes in the lower 48 are on USPS's supplemental list for Ground Advantage: packages leaving them take one day more than the rest of their area to some destinations.
USPS added this day on April 1, 2025 for Post Offices serving ZIP codes more than 50 miles from their regional processing center.
To see if your post office is on USPS's RTO list (Regional Transportation Optimization), use our USPS RTO lookup by ZIP code.
The states with the most listed ZIPs: California 779, Texas 680, Florida 642, Pennsylvania 567, Ohio 535, New York 523.
Type your full 5-digit origin in the calculator. If your ZIP is on the list for the destination you chose, the result says so and the extra day is already included.
Which states are slowest for Ground Advantage?
Sending from Oregon averages 4.45 days to the rest of the lower 48, the slowest of any state; sending from Washington, DC averages 3.00, the fastest.
- Slowest origins: Oregon 4.45, Nevada 4.45, Washington State 4.43, Idaho 4.39, Arizona 4.30 days.
- Fastest origins: Washington, DC 3.00, Delaware 3.07, Ohio 3.15, New Jersey 3.17, Rhode Island 3.24 days.
- Slowest to reach: Oregon 4.44, Washington State 4.34, California 4.31, Idaho 4.22, Nevada 4.16 days.
The West Coast and the Mountain states have the longest standards, so they are slow both ways. The full ranking for the main mail classes, with the data files to download, is on the USPS delivery times by state page.
What is USPS Ground Advantage?
USPS Ground Advantage is the Postal Service's ground package service, launched on July 9, 2023, for packages up to 70 pounds and 130 inches of length plus girth, with tracking and up to $100 of insurance included. It replaced three older services, so any page that still lists them is out of date.
What it replaced (July 9, 2023)
Three overlapping ground products became one, with one set of service standards.
- First-Class Package Service (packages under 16 ounces): now the light tier of Ground Advantage
- USPS Retail Ground (heavier packages at the counter): now Ground Advantage
- Parcel Select Ground (commercial ground): now Ground Advantage; Parcel Select remains only for bulk entry at USPS facilities
My Ground Advantage package is late. What now?
Give it the published standard plus two days, then act: check the tracking for the last scan, and file a Missing Mail search on usps.com, which USPS accepts from 7 days after the mailing date.
The standard is the plan for the route, not a guarantee, and Ground Advantage has no money-back date.
If the package was insured and it is lost or damaged, the $100 of included insurance is claimed online with the tracking number and proof of value.
Two things that look like delays and are not: a package mailed on Saturday loses Sunday and lands a day later than you expect, and a package from a ZIP on the supplemental list carries an extra day from the start. The calculator accounts for both.
Ground Advantage pros and cons

Does USPS Ground Advantage deliver on Saturday?

Does the weight of the package change the delivery time?
No. USPS publishes one standard for packages under 16 ounces and one for 16 ounces to 70 pounds, and in the current directory (October 1, 2026) the two are identical on every route, Alaska, Hawaii and the territories included.
Why is my Ground Advantage package taking so long?
The days USPS publishes are a service standard, the plan for the route, not a guarantee.
Ground Advantage moves by truck through the regional network, and USPS counts Sundays as transit days, except (since April 2025) the Sunday right after a Saturday mailing (holidays never count), so a 5-day route can span a weekend.
If the package is more than two days past the standard, check the tracking for the last scan; you can file a Missing Mail search 7 days after the mailing date.
What did USPS Ground Advantage replace?
USPS Ground Advantage launched on July 9, 2023 and replaced three services: First-Class Package Service, USPS Retail Ground and Parcel Select Ground.
Packages up to 70 pounds and 130 inches of length plus girth travel on it, with tracking and up to $100 of insurance included.
Does Ground Advantage go to Alaska, Hawaii, Puerto Rico and military addresses?
Yes. USPS publishes Ground Advantage standards for Alaska, Hawaii, Puerto Rico and the territories, and since October 1, 2026 they are long for every package weight.

Some Alaska and Hawaii ZIP codes have their own, longer standard, and the calculator includes it for your exact ZIP pair.
Military (APO/FPO/DPO) mail can take much longer, so the calculator gives no date for those ZIP codes: check USPS's military mail page.
