Nearby places to review with your team

Decide which of these places belongs in your accepted territory and which requires a different branch or an out-of-area response. Distances are straight-line calculations between Census internal points, not driving distances or distances between boundaries.

Confirm instructions for nearby places in another state

The nearby-place list for Chester city, IL, includes Lithium CDP, MO; St. Mary city, MO; Brewer CDP, MO; Ste. Genevieve city, MO. Their proximity does not establish that your business accepts requests there.

1. Review each listed place separately in the worksheet. Leave it unreviewed until your business confirms the accepted addresses or boundaries.
2. For accepted requests, record whether the same branch and primary or backup contact applies on both sides of the state line.
3. Write the coverage hours and time zone used by each contact schedule. Do not infer the schedule from a state name or the distance between places.
4. Test an after-hours request from each accepted state and an out-of-area request. Agree on the message, handoff, and fallback before using the instructions.

This is a planning checklist, not confirmation of AnSer availability, road access, or permission to perform a regulated service across state lines.

Turn geography into approved call instructions

• Record the actual addresses, ZIP codes, or boundaries your business accepts. Nearby places are suggestions to review, not automatically included territory.
• Assign the primary and backup contact for each accepted area and coverage period.
• Specify what the answering team may say when an address is uncertain or outside your territory.

Use the after-hours escalation checklist to define the handoff after the responsible contact has been identified.
