This Postnet barcode was found on the floor next to where the puppies were last seen.

Patty knows that Postnet (Postal Numeric Encoding Technique) is a barcoding system used by the United States Postal Service to direct mail. As each piece of mail is processed, a barcode is printed on the envelope indicating the zip code to which the mail is addressed. The barcode is made up of full bars (representing a “1”) and half bars (representing a “0”) in a pattern that encodes the characters of the zip-code using a binary representation.

The barcode starts with a full bar and ends with a half bar & full bar, then each number in the zip code is converted to a four-digit binary representation (e.g. 0010 = “2”), and there is a separator bar between each number in the zip code.

Since you are an expert on binary numbers, you take away all the separators and determine that the zip code is as follows:

1. Can you determine the zip code from this clue?
