known as the inward code, contains the postcode sector and postcode unit. United States In the United States, addresses are generally formatted as follows: The street address line can take a number of alternate formats: "GENERAL DELIVERY" marks the item to be held for pickup from the post office (see ) Some street names are simply the names of highways, like "KY STATE HIGHWAY 625" (a Kentucky state highway), "INTERSTATE 55 BYP" (an auxiliary Interstate bypass), "FM 1200" (a "farm to market" road) or "LOOP 410". In rural areas, mail is addressed according to the mail route rather than the physical street address. The street line might be something like "RR 9 BOX 19-1A" (a "rural route", previously RFD or RD "rural delivery") "HC 68 BOX 23A" for "highway contract" routes (formerly "star routes") The physical street address may appear in the line above the "RR" line without hindering delivery. In Hawaii and Southern California, some addresses have a hyphen in the street number, which should not be removed if matched to the ZIP+4 file. All addresses in the New York City borough of Queens have hyphens, for example "123–45 QUEENS BLVD". In Utah, some addresses are given in a grid style, where the "street name" consists of a cardinal direction, a number that is a multiple of 100, and an orthogonal cardinal direction. For example, "401 West 500 North" is on the grid in St. George, Utah, on the road West 500 North between its intersections with North 400 West and North 500 West. In Wisconsin and northern Illinois, grid addresses are sometimes written as a sequence of numbers and directional letters, e.g. "N6W23001 BLUEMOUND RD". In Puerto Rico, street addresses often include an urbanization or condominium name. The USPS allows for Spanish conventions on the island. United States Virgin Islands street addresses sometimes include only an estate name or a street name with no number, and many street names do not have common suffixes like "Street" or "Road". Notes: Traditionally, only the United States Postal Service (USPS) has been permitted to deliver to a P.O. Box. For this reason the recipient may choose to insert their physical (aka street) address in the second line, expanding the complete address to four lines. Providing both allows a sender to ship via the USPS or via a private carrier. Some USPS facilities allow a user of a P.O. box to use
