Blocking Users by Country

The Ipregistry API enables content restriction from a list of countries.

Here is a Javascript code snippet example to detect users country and take action:

// List of country codes to block
const blacklist = ['US', 'CA', 'UK', 'FR'];

// Ipregistry API invocation
fetch('https://api.ipregistry.co/CLIENT_IP?key=YOUR_API_KEY&fields=location.country.code')
    .then(function (response) { return response.json(); })
    .then(function (payload) {
        const userCountryCode = payload['location']['country']['code'];
        if (blacklist.includes(userCountryCode)) {
            // User is not allowed: redirect, show/hide an element or what you need
        } else {
            // User is allowed: optionally perform an action
        }
});

Line 2 defines the countries you want to block based on their 2-letter ISO 3166-1 alpha-2 code. Any world country is globally identified by a unique ISO 3166-1 alpha-2 code. You can easily find the code associated with a country on Wikipedia.

Line 4 calls the Ipregistry API to retrieve IP data for the client IP CLIENT_IP. For this sample, the call is performed by using the Fetch API. The option &fields=location.country.code is used to retrieve the country code only, which reduces bandwidth consumption and latency.

Line 7 extracts the user country code from the response that was received.

Line 8 checks if the user country code is blacklisted.

Line 9 contains the action to perform for blacklisted users.

Line 11 optionally defines the action to perform for whitelisted users.
