Design carriers Lookup & Develop RespOrg Lookup Site

# Build a Toll-Free Number Lookup Website

We are looking for an experienced **full-stack developer** to build a website that provides a toll-free number lookup service.

The website should allow users to enter a toll-free phone number and retrieve available information about the **RespOrg, telephone company/carrier, and associated company**.

The overall functionality can be similar to existing toll-free lookup websites as an **example of the type of service we want to build**, but the website must have our **own branding, design, backend, and data sources**.

## Required Features

### 1. Toll-Free Number Search

* Simple and user-friendly search interface
* Allow users to enter a 10-digit toll-free number
* Support different formats, for example:

* `800-555-1212`
* `8005551212`
* Support vanity numbers, for example:

* `800-FLOWERS`
* Search button to submit the lookup
* Automatically process/normalize the number where required

### 2. Search Results

After submitting a number, display available information such as:

* Toll-free number entered
* Responsible Organization / RespOrg
* Telephone company/carrier
* Company name, if available
* Contact/referral number, if available
* Other relevant information available from the data source
* Clear message if no information is found

### 3. Input Validation

The system should:

* Validate toll-free number formats
* Handle invalid numbers
* Handle non-toll-free numbers
* Handle unavailable or unrecognized numbers
* Display clear and user-friendly error messages
* Prevent unnecessary or abusive lookup requests

### 4. Responsive Design

The website should be:

* Mobile-friendly
* Responsive on desktop, tablet, and mobile
* Fast loading
* Clean and modern
* Easy to navigate
* Professional looking

### 5. Backend & Data Integration

Develop a backend to process toll-free number lookup requests.

The developer will need to identify and recommend a **reliable API, database, or telecom data source** that can provide information such as:

* RespOrg
* Toll-free carrier
* Company information
* Number status/details

The developer should explain:

* Which data source/API will be used
* What information it provides
* API/data pricing
* Usage limitations
* How frequently the data is updated
* How the data can be maintained in the future

### 6. Admin Panel – Optional

An admin panel may be required for:

* Monitoring lookup activity
* Viewing search logs
* Monitoring API usage
* Managing data sources
* Configuring search limits
* Managing system settings
* Viewing basic statistics

### 7. Security & Abuse Protection

Since the service will be publicly accessible, implement:

* API security
* Rate limiting
* Input sanitization
* Search/request limits
* Basic anti-bot protection
* Error logging

## Technology

We are open to recommendations regarding the technology stack.

The final solution should be:

* Secure
* Scalable
* Fast
* Easy to maintain
* Well documented
* API-driven where appropriate
