# Common Mistakes in Franchise Territory Mapping (and How to Avoid Them)

Seven mapping pitfalls routinely create unhappy franchisees and messy FDDs. Here’s how to fix each with a repeatable playbook.

## 1) Designing with circles instead of travel time

**Why it’s a problem:** Distance isn’t the same as accessibility. A 3‐mile ring can be 5 minutes in a suburb or 20 downtown.

**Fix:** Build territories with [drive‐time polygons](/content/knowledge-base/using-isochrones/index.html) based on real road networks and typical conditions.

### 2) Building on ZIP Codes

**Why it’s a problem:** ZIPs are postal routes that change and don’t cleanly map to polygons.

**Fix:** Avoid ZIPs for boundary definitions; if required for ops, use Census ZCTAs as a proxy, version the list, and mirror it in Item 12.

### 3) Sizing on stale or noisy data

**Why it’s a problem:** Decennial counts age; ACS samples can be noisy for small areas.

**Fix:** Use an annually updated gridded dataset ( [LandScan](/content/knowledge-base/landscan-deep-dive/index.html) or [WorldPop](/content/knowledge-base/worldpop-constrained-deep-dive/index.html)) for base population and document the vintage; use ACS for attributes with MOE awareness.

### 4) No population parity

**Why it’s a problem:** Equal geographic area ≠ equal opportunity.

**Fix:** Define a [population threshold](/content/knowledge-base/search-sort-filter/index.html) and grow drive‐time polygons until each territory reaches the target.

### 5) Ignoring competitive gravity

**Why it’s a problem:** Two nearby units cannibalize each other; so do strong competitors.

**Fix:** Evaluate competitor POIs and, where available, use gravity models (e.g., Huff) to understand overlap risk before awarding.

### 6) Leaving Item 12 silent on alternative channels

**Why it’s a problem:** If HQ, marketplaces, or brand.com can sell into a territory, franchisees need to know.

**Fix:** Ensure Item 12 addresses internet and alternative channels explicitly and that your award packet shows how this interacts with the map.

### 7) Not archiving territories

**Why it’s a problem:** Without a dated shapefile/PDF, renewals and transfers re‐litigate boundaries.

**Fix:** [Export](/content/knowledge-base/export-zip-postal-codes-franchise-territories/index.html) and store both GIS and human‐readable artifacts with source and parameters.

### Putting It All Together in Population Explorer

- Start with a candidate address and **generate drive‐time** options (10/15/20 minutes).
- Apply a **population threshold** using LandScan or WorldPop to equalize potential.
- **Overlay competitors** and check for cannibalization risk.
- **Export artifacts** and attach them to the award record; replicate the rules in Item 12.

### Conclusion

Territories that sell fast and stand up later aren’t accidents—they’re the product of a clear method. Move from circles and ZIPs to drive‐times, gridded population, and documented rules.
