# Interzoid Get Area Code From Number API

The Interzoid Get Area Code From Number API extracts the area code from a full North American telephone number and returns the associated city, state or province, and country. Agents pass the full number as a query parameter and receive parsed location data without needing to slice the digits themselves. The single GET /getareacodefromnumber endpoint authenticates with a license key passed as a query parameter and returns JSON.

## For AI agents

Take a full phone number and return the area code plus its city, state, and country. One GET endpoint, license-key auth.

## Scope

Does not validate phone numbers for deliverability, identify carriers, or resolve numbers outside the North American Numbering Plan - use for North American phone-to-geography lookup only.

## Capabilities

- Extract the area code from a full North American phone number string
- Return city, state, and country geography for the parsed area code in a single call
- Enrich raw phone-number columns in a CRM without pre-parsing the digits
- Detect malformed or non-North-American numbers by inspecting the response
- Tag inbound call records with caller geography starting from the raw caller ID

## Use cases

### Phone column enrichment without pre-parsing

When a CRM stores raw phone numbers in a single text column, the Interzoid Get Area Code From Number API extracts the area code and returns city, state, and country in a single call. This removes the need to write regex parsing logic for the many ways phone numbers are formatted in user-entered data.

Example prompt: Call /getareacodefromnumber with number=4155551212 and write the returned City and State values onto the contact record.

### Caller-ID-based call routing

Telephony platforms send the inbound caller ID directly to the Interzoid Get Area Code From Number API and route the call based on the returned state or country. This avoids maintaining an internal mapping of area-code prefixes to regions and handles formatting variations transparently.

Example prompt: For inbound caller ID +1-312-555-0100, call /getareacodefromnumber and route the call to the queue assigned to State=Illinois.

### Bulk phone-list segmentation

Marketing teams segment outbound call lists by region by sending each phone number through the Interzoid Get Area Code From Number API and grouping records by state or country. The endpoint accepts one number per call, so batches are run with a small thread pool against the rate limit on the account.

Example prompt: Iterate the leads.csv file, call /getareacodefromnumber for each phone column, and write the State value to a new region column.

### AI agent inline phone enrichment

An AI agent processing customer support tickets discovers the Interzoid Get Area Code From Number API through Jentic's intent search and resolves caller geography mid-conversation. Jentic stores the Interzoid license key in the credential vault and injects it as the license query parameter at execution time, so the agent never sees the raw key.

Example prompt: Search Jentic for 'extract area code from a phone number', load the Interzoid Get Area Code From Number operation, and execute it for the caller's phone number.

## Key endpoints

| GET | `/getareacodefromnumber` | Extract area code from a phone number and return its geography |

## Key resources

- **Phone number area code lookup** — Single GET operation that accepts a full phone number, extracts the area code, and returns the associated city, state, and country.

## Why Jentic

- **Setup:** Wiring the Interzoid Get Area Code From Number API by hand means passing your licence key as a query parameter on every call and remembering the single /getareacodefromnumber endpoint. Through Jentic you install once, import the Interzoid Get Area Code From Number API from the API Directory, store the licence key once, and your agent calls it.
- **Permission scoping:** This API exposes one read-only operation, GET /getareacodefromnumber, with the phone number in the query, so limit the agent to that operation. It performs no writes or deletes, so there is nothing destructive to add.
- **Credential handling:** Your Interzoid licence key is stored once, encrypted, by your own Jentic One instance and injected as the license query parameter at execution time. It never enters the agent's prompt, logs, or context.
- **Discovery method:** Agents search Jentic by intent such as 'extract the area code from a phone number', and Jentic returns the GET /getareacodefromnumber operation with its parameter schema so the agent calls the right endpoint without browsing the reference docs.

## Related APIs

- **Interzoid Get Area Code API** — Same geographic lookup but takes a pre-extracted three-digit area code instead of a full phone number
- **Interzoid Get Global Phone Number Information API** — Handles international phone numbers and returns richer metadata than the North-America-only area code lookup
- **Interzoid Zip Code Detailed Info API** — Returns city, state, county, and time zone for a US zip code, complementing phone-based geography

## FAQ

### What authentication does the Interzoid Get Area Code From Number API use?

The API uses a license key passed as the license query parameter on every request to /getareacodefromnumber. Through Jentic the license key is held in the credential vault and injected at execution time, so the agent never handles the raw key.

### Can I pass phone numbers with formatting like dashes or parentheses?

Yes. The /getareacodefromnumber endpoint extracts the area code from the digits in the number string, so common formats such as 415-555-1212 or (415) 555-1212 are accepted.

### What are the rate limits for the Interzoid Get Area Code From Number API?

The OpenAPI spec does not publish a numeric rate limit. Interzoid enforces per-license-tier quotas on the account dashboard, so check your account page before running large batches.

### How do I parse a phone number through Jentic?

Install the SDK with pip install jentic, search for 'extract area code from a phone number', load the Interzoid Get Area Code From Number operation, and execute it with the number parameter set to the phone string.

### Does the Interzoid Get Area Code From Number API work for international numbers?

It targets North American Numbering Plan numbers, covering the United States, Canada, and several Caribbean countries. For numbers outside this plan, use the Interzoid Get Global Phone Number Information API instead.

### Can I limit what my agent is allowed to do with the Interzoid Get Area Code From Number API?

Yes. Because Jentic One is self-hosted, you set the rules that decide which operations and credentials your agent may use. This API exposes a single read-only operation, GET /getareacodefromnumber, so you can allow only that call and scope the agent to phone-to-geography lookups. It performs no writes or deletes, so there is nothing destructive to grant, and the Interzoid licence key stays with your instance rather than being exposed to the agent.
