Shipping Boston to Philadelphia (2026)
Shipping Boston to Philadelphia (2026)
Boston to Philadelphia spans roughly 310 miles along the Northeast Corridor, placing it in USPS Zone 3. This short-haul route benefits from the densest carrier infrastructure in the country — I-95 connects both cities directly, and sorting facilities in Connecticut and New Jersey handle massive package volumes daily. The result is fast transit times and low rates that make shipping between these two cities straightforward and affordable.

Cheapest Option by Package Size
Small packages (under 1 lb): USPS Ground Advantage at ~$3.75–$4.75 is the top pick. First-Class Package Service handles items under 13 oz for ~$3.25–$4.00. These are among the lowest rates you’ll see for any shipping route.
Medium packages (2–5 lb): USPS Ground Advantage runs ~$5.25–$8.50. UPS and FedEx Ground come in at ~$8.00–$12.00. Zone 3 calculated rates are low enough that USPS flat-rate boxes don’t make financial sense — stick with calculated pricing.
Heavy packages (10–25 lb): UPS and FedEx Ground range from ~$13.00–$22.00. USPS Ground Advantage at ~$12.00–$19.00 holds its own. The Large Flat Rate Box at ~$22.80 only makes sense if your package exceeds 20 lb and fits the box — otherwise, calculated rates win at this distance.
Large or oversized packages (25+ lb): UPS Ground and FedEx Ground handle these at ~$22.00–$38.00. Short-distance pricing keeps these rates manageable even for heavy shipments. For very large items, regional LTL carriers along the I-95 corridor offer competitive quotes.
Delivery Time Comparison
| Speed | USPS | UPS | FedEx |
|---|---|---|---|
| Economy / Ground | 2–3 days | 1–3 days | 1–3 days |
| Expedited / 2-Day | 1–2 days (Priority) | 2 days | 2 days |
| Overnight / Express | 1 day | 1 day | 1 day |
At 310 miles, ground service is fast. UPS and FedEx Ground often deliver next-day or within two days on this route. USPS Priority Mail routinely arrives in 1–2 days, effectively functioning as an affordable express option.
Tips for This Route
-
Calculated rates always beat flat rate here. At Zone 3, there is no package weight where USPS flat-rate boxes offer a better deal than calculated pricing. Always compare, but expect calculated rates to win.
-
Ground service is your express option. UPS and FedEx Ground on a 310-mile route often deliver next-day. Test ground service before paying for 2-Day or overnight — you may get the same speed at a fraction of the cost.
-
Drop off early for same-day processing. Packages dropped off before carrier cutoff times in Boston (typically 3–5 PM) enter the sorting network that evening and often arrive in Philadelphia the next business day via ground service.
-
Take advantage of high carrier competition. The Northeast Corridor has the highest concentration of carrier facilities in the country. This competition keeps rates low and service quality high. Shop rates between carriers — the price differences are often smaller than on longer routes, but the savings still add up over volume.
