# Allowed ZIP codes

> Limit AI calls to contacts in the ZIP codes you serve, and make sure your contacts' ZIP codes are complete so they aren't skipped.

- Section: Using the app (manual) › Compliance
- Web page: https://docs.biglysales.com/manual/allowed-zip-codes
- Availability: Set by your Bigly account team or through the MCP
- Video: placeholder — "Restricting calls to your service area" (not yet recorded)

The **allowed ZIP codes** list limits your AI calls to contacts in specific ZIP codes. Use it when you can only serve certain areas, are licensed only in some places, or want a campaign to stay inside your service area.

- **No list (the default):** all ZIP codes are allowed.
- **With a list:** the AI agent only calls contacts whose ZIP code is on the list. Everyone else is skipped, **including contacts with no ZIP code at all**.

In the app, the list is set up by your Bigly account team: contact support to add, change or remove it. If you use the [Bigly MCP](https://docs.biglysales.com/mcp.md), you can also change it yourself from your AI assistant.

## Before you start

- Make sure your contacts have ZIP codes. Map the ZIP column when you [import contacts](https://docs.biglysales.com/manual/importing-contacts.md), or edit them on the [contact's page](https://docs.biglysales.com/manual/contacts.md).
- Prepare your list of 5-digit US ZIP codes.

## Ask for a ZIP code list

1. Contact support and send the ZIP codes you want to allow, separated by commas, for example `90210, 10001, 60601`.
2. Tell them if the list should replace your current one or be added to it.

Only US 5-digit ZIP codes can be used. Extra characters are removed, so `90210-1234` becomes `90210`. Entries that don't contain five digits are rejected.

## Change the list with your AI assistant

If your account uses the [Bigly MCP](https://docs.biglysales.com/mcp.md) and your role can update AI settings, ask your assistant, for example *Only call zip codes 30301, 30302 and 30303*. It shows you a preview of the new list, and nothing changes until you confirm. One invalid entry stops the whole change. See [AI settings through the MCP](https://docs.biglysales.com/mcp/ai-settings.md).

## Check your contacts before a campaign

When you start an AI blast on the [Calls](https://docs.biglysales.com/manual/calls.md) page, Bigly checks the call list's ZIP codes:

| What Bigly finds | What you see |
|---|---|
| Half or more of the contacts have no ZIP code | A red **error**. You can't start until you fix it. |
| Some contacts have no ZIP code | A yellow **warning**, such as *12% of ZIPs are missing*. You can still start. |
| Half or more of the contacts with a ZIP code are outside your allowed list | A red **error**. |
| Some contacts are outside your allowed list | A yellow **warning**. |

Contacts skipped because of their ZIP code are recorded as blocked, so you can see them in your [call statistics](https://docs.biglysales.com/manual/call-statistics.md).

## Fix missing ZIP codes

- **For new imports:** map your file's ZIP or postal code column to the ZIP field. See [Importing contacts](https://docs.biglysales.com/manual/importing-contacts.md).
- **For existing contacts:** open the contact and add the ZIP code to their location, or re-import the list with the ZIP column mapped.

ZIP codes are stored as 5 digits. Entries with fewer than five digits, or `00000`, are not accepted.

## Common questions

**Do changes apply straight away?** Yes. Calls already waiting to go out use the new list when they're placed.

**Does the list affect texts or calls I make myself?** The allowed ZIP code list applies to AI calls.

**Can I block specific ZIP codes instead?** The list only allows ZIP codes; it can't exclude them. To keep one campaign inside an area, use the **State** and **City** filters when you build its audience.
