Check VAT number in Bulgaria via API

In the increasingly complex landscape of global trade, verifying the validity of VAT numbers is crucial for compliance and error reduction. This is especially true for countries with specific local rules like Bulgaria. Using EuroValidate API simplifies this process, providing a dedicated service for checking Bulgarian VAT numbers quickly and accurately.

Understanding the Bulgarian VAT System

To effectively validate VAT numbers, it is essential to understand the structure of Bulgarian VAT numbers. Typically, these numbers consist of a country code (BG) followed by a nine or ten-digit number. Common issues include incorrect formatting and outdated numbers, which can lead to compliance errors and financial penalties.

Why Use an API for Checking Bulgarian VAT Numbers?

Using a dedicated API offers numerous benefits over manual checks or third-party platforms:

  • Accuracy: The API is localized for Bulgarian regulations, ensuring high accuracy in validation results, crucial for maintaining regulatory compliance.
  • Efficiency: Automating VAT checks reduces human error and saves time compared to manual processes.
  • Seamless Integration: With developer-first documentation and robust API endpoints, integration is streamlined into existing workflows.

How Our API Works: Key Components & Architecture

The EuroValidate API provides several key components and supports standard REST operations. Here’s a quick overview:

  • Endpoints: Use GET /v1/vat/{number} for validating VAT numbers directly.
  • Authentication: API key-based authentication; secure and straightforward.
  • Error Handling: Tailored error response structure, focusing on typical VAT issues found in Bulgaria.
  • Response Structure: Includes fields like vat_number, country_code, status, company_name, company_address, and meta details such as confidence and response_time_ms.

Latency Considerations

While highly efficient, consider latency influenced by network conditions. Our response times typically range in milliseconds, depending on the validation complexity and requested data volume.

Step-by-Step Integration Guide

  1. Sign Up: Visit EuroValidate to get your free API key.
  2. Setup: Integration is straightforward with these examples:

Python Example

Make sure to install the necessary package:

pip install eurovalidate
Enter fullscreen mode Exit fullscreen mode
import requests

API_KEY = 'your_api_key_here'
url = 'https://api.eurovalidate.com/v1/vat/BG123456789'

headers = {'Authorization': f'Bearer {API_KEY}'}
response = requests.get(url, headers=headers)

if response.status_code == 200:
    data = response.json()
    print("Valid VAT Number:", data['vat_number'], "Status:", data['status'])
else:
    print("Error:", response.json())
Enter fullscreen mode Exit fullscreen mode

Node.js Example

Install the SDK:

npm install @eurovalidate/sdk
Enter fullscreen mode Exit fullscreen mode
const axios = require('axios');

const API_KEY = 'your_api_key_here';
const url = `https://api.eurovalidate.com/v1/vat/BG123456789`;

axios.get(url, { headers: { 'Authorization': `Bearer ${API_KEY}` } })
    .then(response => {
        console.log("Valid VAT Number:", response.data.vat_number, "Status:", response.data.status);
    })
    .catch(error => {
        console.error("Error", error.response.data);
    });
Enter fullscreen mode Exit fullscreen mode

PHP Example

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://api.eurovalidate.com/v1/vat/BG123456789",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_HTTPHEADER => array(
    "Authorization: Bearer your_api_key_here"
  ),
));

$response = curl_exec($curl);
curl_close($curl);

$data = json_decode($response, true);
if (isset($data['vat_number'])) {
    echo "Valid VAT Number: " . $data['vat_number'] . "\n";
} else {
    echo "Error: " . $response . "\n";
}
Enter fullscreen mode Exit fullscreen mode

Code Examples & Practical Use Cases

For ease, adjust the sample VAT number for real environments:

  • Valid Response Example: Using NL820646660B01
  • Invalid Response Example: Using FR40303265045

Both examples demonstrate API’s effectiveness in handling legitimate and erroneous data promptly, providing clear status updates and metadata.

Frequently Asked Questions (FAQs)

  • What if I encounter validation errors? Check the format and country code first. Ensure your integration handles these errors gracefully as shown in code examples.
  • How do I ensure security and performance? Use API keys securely, regularly monitor response times, and optimize retry logic to manage occasional network glitches.
