Mail Delivery Time: Dover, NH to Boston, MA

The original question asks about letter delivery, but the provided answer gives travel times by car, train, and foot. Here are the actual USPS mail delivery estimates for this ~65-mile route:

Why It's Fast

• Both cities are in the same USPS processing region (Boston Metro / Northern New England).
• Mail moves overnight via truck/air between sectional center facilities.
• Local delivery occurs the next business morning.

For Reference: Travel Times (Not Mail)

• By car: ~1 hour 10 min via I-95 / US-4 / Spaulding Turnpike
• By train: Amtrak Downeaster ~1 hr 25 min (Dover to Boston North Station)
• By foot: ~2 days 13 hours (non-stop, unrealistic)

If you drop a letter at a Dover post office by afternoon collection, it will likely reach a Boston address the next business day via First-Class Mail.
