These are some of the most expensive ZIP codes in the country

If you thought 90210 was the swankiest place in California, think again: The most expensive ZIP code in the state is actually Atherton's 94027. Situated next to Palo Alto and Menlo Park, the wealthy Silicon Valley town is a short drive from Facebook's headquarters and home to numerous tech executives, including Sheryl Sandberg and Meg Whitman.

Personal finance site GOBankingRates recently named these the most expensive ZIP codes in almost every U.S. state (with the exception of South Dakota, where there wasn't sufficient data) using numbers provided by Zillow. The ranking compares median home prices from January 2017 for hundreds of ZIP codes across the country, according to Zillow's Home Value Index.

Read on to see the most expensive ZIP code in almost every U.S. state, bearing in mind that, in some cases, complete statewide data wasn't available.
