How does endereco's telephone number verification work?
Number validation takes place in several steps:
Recognition of the country
A country code or the specification of a country is required for recognition. On this basis, the phone number can be identified and, for example, converted into a standardized international spelling.
Recognition of the phone number type
Based on the area code, it can now be determined worldwide whether it is a landline or mobile phone number.
Validity check
Mobile phone numbers can be queried via the SS7 network and checked for the possibility of a connection. Landline numbers can be checked for validity on the basis of mathematical calculations and provider lists. This means you can be sure that these numbers are active at the time of the check.
