Data validation list that depends on partially matched data?

I have 2 worksheets, one has a list of zip codes in column A (all unique) and names in column B, and the other sheet will have the user entering a zip code in column A and column B needs a data validation list that only contains rows from sheet 1 that have a zip code matching the user input, but I need all of the partial matches in the drop down list. So if the user types 385 in A1, B1 will have a drop down list with all of the rows in the zip code list that start with 385. I found a lot of sites on google that talk about making one list that is dependent on the selection of another list, but didn't see anything quite like this.

Post 4 has my sample sheet/expected results.
