872 area code
Both the central Chicago 312 region and the wider 773 region.
872 overlays both 312 and 773 in Chicago. Unlike the older codes, it does not distinguish central Chicago from the rest of the city. For deliveries or service work, collect the full address and any access instructions rather than infer a neighborhood from 872.

Questions about 872
Does 872 cover downtown Chicago or the neighborhoods?
Both. It overlays the 312 and 773 regions. A downtown company and a neighborhood customer can therefore share the same 872 prefix.
Is a 872 call safe to answer?
The 872 prefix identifies a numbering region, not a caller's identity or trustworthiness. Verify an unexpected request by contacting the organization through a number you already know.
Can I get a 872 business number?
Search the available numbers in VeraDial. Inventory changes, so a 872 number is not guaranteed. You can also keep your current carrier number and forward voice calls to a VeraDial line; existing texts stay with your carrier.
