What are the benefits of Phone Number Validation?

Sales representatives and customer service professionals know that having accurate contact information is essential to maintaining good relationships with customers. Unfortunately, bad data can creep into any database over time. Phone number validation is a useful tool for sales and customer service teams to keep their data clean and up-to-date.

Phone number validation can help sales reps avoid frustrating customers with bounced calls and customer service reps avoid wasting time trying to reach disconnected numbers. Validation can also help sales and customer service teams keep track of which contacts have moved to new phone numbers.

Regularly validating your contact data is a good way to maintain accurate records and avoid potential headaches down the road. luckily, there are several simple and effective ways to validate phone numbers.

What are the different types of Phone Number Validation?

There are four main types of phone number validation:

1. Format Validation

2. Line Type Validation

3. Country Code Validation

4. Carrier Verification

Format validation is the most basic type of phone number validation. It simply ensures that the phone number is in a valid format, such as XXX-XXX-XXXX or (XXX) XXX-XXXX.

Line type validation goes a step further by ensuring that the phone number is actually a working landline or mobile number. This is done by checking the line type against a database of known working numbers.

Country code validation is important for international numbers, as it ensures that the country code is correct for the given country. This is especially important for numbers that will be used for SMS or MMS messaging, as the country code is required for routing the message.

Carrier verification is the most comprehensive type of phone number validation. It not only checks the format and line type, but also verifies that the number is active and able to receive messages from the carrier. This is done by sending a test message to the number and checking for a delivery confirmation.
