Question 1

What does NumlookupAPI Phone Validation do?

Accepted Answer

NumlookupAPI is a phone number lookup and validation API providing real-time carrier identification, line type detection, geographic location data, and number format normalization for global phone numbers including Nigerian (+234) numbers. Operated by EverAPI (everapihq), the platform offers a developer-friendly integration path with a free trial requiring no credit card, paid plans from $9.99/month, and a 99.99% uptime SLA on all paid tiers.

The API is designed for businesses that need to validate phone numbers at point of entry, enrich CRM contact data, or screen registrations for invalid or suspicious numbers — without the complexity of a full communications platform.

## What the API Does

A single NumlookupAPI call accepts a phone number and returns:
- **Validity**: Whether the number is a valid, recognized phone number.
- **Number (E.164)**: The number in international E.164 format.
- **Carrier**: The mobile network operator (e.g., MTN Nigeria, Airtel Nigeria, Globacom, 9mobile).
- **Line type**: Mobile, landline, VoIP, or unknown.
- **Location**: Country and sub-national region associated with the number prefix.
- **Country code**: ISO 2-letter country code (NG for Nigerian numbers).

The API integrates with CRM systems, marketing platforms, and custom applications for automated phone number quality management.

## How Developers Use It

GET request to the NumlookupAPI endpoint with the phone number and API key. The response is a JSON object with all available metadata. SDKs and client libraries are available for popular languages through the GitHub repository (everapihq/numlookupapi). Integration is straightforward and can be completed in under an hour.

## Pricing & Fees

- **Free trial**: Available with no credit card required for initial testing.
- **Paid plans**: Start at $9.99/month providing 7,000 API requests per month.
- **Custom plans**: Available for businesses requiring more than 300,000 requests per month.
- All paid plans include unlimited API connections (no concurrent request limit) and the 99.99% uptime guarantee.

## Authentication

API key authentication. The key is passed as a parameter in the API request. Keys are issued immediately after registration.

## Rate Limits

Rate limits are based on monthly request quotas per plan tier. Paid plans come with unlimited concurrent API connections — requests are processed without queuing. Monthly quotas reset each billing cycle.

## Compliance

NumlookupAPI processes phone numbers for validation and lookup purposes. Data handling policies are consistent with standard API service agreements. For Nigerian deployments, the carrier and format data returned supports phone number verification as part of broader user onboarding flows.

## Challenges & Gotchas for Nigerian Developers

1. **No SIM Swap detection**: NumlookupAPI provides carrier and line type data but does not offer SIM Swap detection for fraud prevention. Use Twilio Lookup for SIM Swap signals.
2. **Carrier accuracy with MNP**: Nigerian mobile number portability can cause carrier misidentification after a user switches networks. The API reflects original carrier assignment.
3. **7,000 requests at $9.99**: This is a reasonable starting volume but will be exhausted quickly for apps with active daily registrations. Plan your tier based on expected daily validation volume.
4. **USD billing**: NumlookupAPI charges in USD. Nigerian developers need a USD-capable payment method.
5. **Limited documentation depth**: As a smaller API provider, documentation and community support resources are more limited than Twilio or Abstract API.

## Company Background

NumlookupAPI is operated by EverAPI (everapihq), a developer-focused API company providing a portfolio of data enrichment and validation APIs. The platform is available as an open-source client library on GitHub and through the Rapid API marketplace in addition to the main website.
