An optical character recognition (OCR) system is developed forrecognizing handwritten and handprinted addresses which include aBritish postcode written within character boxes. The system makes use ofsyntactic information concerning postcodes and a postcode database whichinteracts with the character recognition process to ensure that onlyvalid postcodes are recognized. Postulated valid postcodes are thenverified using semantic features of the remainder of the address, toproduce a final postcode which both matches the input characters and iscompatible with the remainder of the address. Preliminary results arepresented to show how the initial stages of syntactic verification canimprove character recognition performance
