Surface mail

From Wikipedia, the free encyclopedia

Surface mail is transported via truck, rail, and ship, rather than by plane, as in this FedEx Ground truck.

Surface mail, also known as sea mail, is mail that is transported by land and sea (along the surface of the earth), rather than by air, as in airmail. Surface mail is significantly less expensive but slower than airmail, and thus is preferred for large or heavy, non-urgent items and is primarily used for sending packages, not letters.


The term "surface mail" arose as a retronym (retrospective term), following the development of airmail – a term was needed to describe traditional mail, for which purpose "surface mail" was coined. A more recent example of the same process is the term snail mail (to refer to physical mail, be it transported by surface or air), following the development of email.[1]

By country[edit]


The Israel Postal Company (Hebrew: דואר ישראל, romanizedDo'ar Yisra'el) offers international surface mail (known as "sea and land mail," (Hebrew: דואר ים ויבשה, romanizedDo'ar Yam v'Yabasha).[2]

United States[edit]

In 2007, the US Postal Service discontinued its outbound international surface mail ("sea mail") service,[3] mainly because of increased costs. Returned undeliverable surface parcels had become an expensive problem for the USPS, since it was often required to take such parcels back.[4]

Domestic surface mail (now "Retail Ground" or "Commercial Parcel Select") remains available.

Alternatives to international surface mail include:

Senders can access the International Surface Air Lift and ePacket services through postal wholesalers. Some examples of such wholesalers include:

  • Asendia USA (accessible through the Shippo website to users who have an Asendia account),[6]
  • Globegistics (now owned by Asendia), and
  • APC Postal Logistics.

If a sender sends an ISAL mailing directly through the USPS (without a wholesaler as an intermediary), the minimum weight is 50 pounds per mailing.[7] ePacket mailings can never be sent directly through the USPS; senders must always use a wholesaler.

Internal newsletters detailed a huge loss for the USPS in the failed delivery of packages sent from the USA via surface. Since the USPS cannot dictate how scores of different countries handle surface mail, and since its agreements required the USPS to take back undeliverable parcels, the losses were mounting.

The reason, probably, why no other dealers offer it: ... it is very difficult and time-consuming to do. Plus, there is no tracking, no insurance, and lots of complaints — as those packages can easily take 60 days to arrive.
