International phone number checks vary wildly across the globe in terms of format. Whether it’s the way they are written, how many digits they have, or even if they contain a plus sign (+), the varying formats can lead to confusion and errors in both personal and business contexts. Understanding and accurately writing a phone number in international format can help reduce communication barriers, ensure you are able to contact someone, and improve your chances of making successful connections.

International Phone Number Checking: Best Practices

As businesses expand their reach to more global customers, it’s important that they have access to accurate and reliable data. This helps to improve customer experience and compliance with regulations such as TCPA and GDPR. Using a global phone validation service like Abstract’s Phone Validation and Verification API allows for more effective marketing campaigns and customer support initiatives by ensuring that the information being used is genuine and up-to-date.

In addition to ensuring that an international phone number is valid, our Phone Validation – International also provides valuable geographic information such as carrier (landline or mobile), line type (mobile or landline), and the time zone of the location. This helps to enhance the quality of a campaign and provides crucial insight into potential issues such as call center locations, porting details and more.

As a rule of thumb, it’s best to drop the first digit of an international number, and replace the plus sign (+) with your country’s exit code. This makes the number easier to read, and ensures that it will be interpreted correctly by any systems that you are working with.
