Hey @Qiming_Shi ! Thanks for the great question. Apologies for the delay - had to do some research on my end for this
You won’t be able to match SafeGraph data directly to the 9 digit ZIP code. The Places data includes the full address with 5-digit ZIP. However, a workaround is to enter into the address into a tool like the USPS’s zipcode search or SmartyStreets’ API to get the full 9-digit zip+4. Hope that’s helpful!
To prevent any further questions from being overlooked, I’ll go ahead and close this thread out. If you have any more questions or follow-up questions, we’re always here to help! Just be sure to make a new post to help, as we aren’t monitoring old threads at this time. Thanks!
