Abstract
A postal code distinguishing apparatus extracts characters from an address code appearing on a mail article, forms words from the extracted characters, stores in a memory a set of key words (i.e., "ATTN", "TEL", "P.O. BOS", etc.) which indicate that a numeric code on the same line is not a postal code, compares the key words with the extracted words, and sorts the mail articles accordingly. In this manner, the various lines of the address code are "eliminated" such that the numeric code on the remaining line is automatically read out as the postal code.
