Zipcode sequences refer to the chronological ordering of United States Postal Service (USPS) ZIP codes. This ordering is based on the numerical value of the ZIP code itself, not on geographical proximity or any other spatial relationship. When ZIP codes are arranged in ascending order, they generally reflect a progression from east to west across the United States, although there are numerous exceptions and complexities due to how ZIP codes were originally assigned and have evolved.

The first three digits of a ZIP code, known as the ZIP code prefix, typically indicate a broader geographic region. For example, ZIP codes starting with 0 are generally in the northeastern United States, while those starting with 9 are in the western United States. This east-to-west progression is a common characteristic observed when examining a sequence of ZIP codes. However, the assignment of ZIP codes is driven by mail delivery routes and population density, which can lead to non-contiguous or overlapping areas.

Understanding zipcode sequences can be useful in various applications, including data analysis, market research, and logistical planning. For instance, analyzing trends or patterns across a range of ZIP codes ordered numerically might reveal insights into regional differences in consumer behavior or delivery times. While the numerical sequence provides a framework, it's important to remember that it does not perfectly map to a continuous geographical path.
