Craigslist online classifieds are a useful tool for locating many second-hand or brand new items. If you are seeking a specific item, and prefer to buy it from a private sale instead of a mass retailer, you can search Craigslist by the part number to simplify the search process. Learning how to use the search field properly will eliminate the need to spend large amounts of time scrolling through irrelevant ads. Save your time investment and view only the ads that are relevant to the part number you need.
Load the Craigslist website and click into the section you want to search. You can search an entire category by clicking the header, for example "For Sale".
Enter the item number in the "Search For" box. Click the drop down menu beside the search field and narrow down the category you want to search in, if desired.
Select the option to search just the title or the entire Craigslist post for the item number. Click "Search" and review the list of results.
