Spanish street names generally have the suffix element preceding the root street name, making it a prefix. The AMS database has no prefix element, so Spanish prefixes are stored in the street name field along with the actual street name.
I51.2 Numbered Streets
I51.3 House Numbers
Hyphens in the address range are sometimes necessary. When addresses contain block numbers and house numbers, use a hyphen to separate the block number from the house number. Some identifiers commonly used to separate these elements such as Bloque, Número, Casa, Lote, and # must not be included.
An urbanization denotes an area, sector, or residential development within a geographic area. Commonly used in Puerto Rican urban areas, it is an important part of the addressing format, as it describes the location of a specific street.
In Puerto Rico, identical street names and address number ranges can be found within the same ZIP Code. In these cases, the urbanization name is the only element that correctly identifies the location of a particular address. Generally, the abbreviation URB is placed before the urbanization name.
Generally, urbanizations names are not repeated within five-digit ZIP Codes and, in most cases, are served by the same carrier route. Therefore, a list of urbanization names serves as five-digit ZIP Code verification.
The following urbanization names stand alone and do not require the use of the abbreviation URB.
I51.5 Post Office Box
Always use PO BOX to identify Post Office Boxes. Do not use Spanish words.
PO Box addresses are often written in various forms, e.g., Caller, Call Box, GPO Box, APARTADO. The only authorized format is PO BOX. All other forms should be changed to “PO Box” on the mailpiece.
The postal station name is not needed on the mailpiece because the ZIP Code identifies the station. However, when the station name appears on the mailpiece, it should be placed above the delivery line.
I51.6 Rural Routes
The proper format for rural route addresses is RR_____ Box_____. Do not use the words Rural, Ruta Rural, RFD, Buzón, or BZN. A leading zero before the route number is not necessary.
There should be no additional designations such as sector names on the delivery address line of rural addresses. Names of sectors used together with route and box numbers can create potential matching difficulty. Mailers are required to use only one address style. Eliminate unnecessary information.
I51.7 Highway Contract Routes
The proper format for highway contract route addresses is HC____BOX____. It is basically the same format utilized for rural routes. Likewise, a leading zero before the route number is not necessary.
I51.8 Last Line
An essential element in a complete address is the last line which must include the city, state and ZIP Code. Certain areas of the San Juan metropolitan area are identified by residents with names such as Condado, Barrio Obrero, and Rio Piedras. These are not valid last line entries. SAN JUAN is the only valid city name for addresses within San Juan.
