The database, “U.S. Phone and Address Directories, 1993-2002,” was recently updated or released on Ancestry.com.
The database can be searched by phone number by entering in the number (without any dashes as three separate numbers) in the keyword box:
217 555 2132
It will pull up 9-digit zip codes that have the last four digits of the phone number. So this search could pull up results with the phone number:
- 217-555-2132 and any zip code, or
- 217-555-xxxx and a zip code of aaaaa-2132.
