AS/400 & Tolls: Stop Validation Overview

When using PC*Miler|Streets, the best match for address location lookups can be accomplished using the guidelines below. These rules apply to batch or interactive integration. It is recommended that a validation (VA) request always precede each mileage request, especially where street addresses are included, to avoid misleading or incomplete output.

When you input a street address, use a city and state abbreviation whenever possible

Example: Princeton, NJ;1000 Herrontown Road The comma between the city and state is optional. The semicolon between the state abbreviation and the street address is required. Use a street number.

Example: Princeton, NJ;1000 Herrontown Road as opposed to “Princeton, NJ;Herrontown Road”. If Herrontown Road is 50 miles long and no address is included, the returned mileage could be very inaccurate.

When a street address is not supplied, do not send a semicolon

Example: Send 08540 as opposed to “08540;” — a semicolon will cause the server to look up a blank address (unnecessary).


Three examples of correct input:

  • Trenton, NJ;21 Olden Avenue
  • New York, NY;118 Broadway
  • 20001
