How Does Bulk Phone Number Verification Work?

Bulk phone number verification checks an entire list of phone numbers ‘in Bulk’ rather than separately one-by-one. This tool is designed for companies with large phone number lists. The validation process usually takes only a few minutes.

Phone Validator does the following:

  • Checks each number against the data provided by telecom carriers and providers in 240 countries across the globe.
  • Verifies if the number is active.
  • Collects detailed information for each number, including phone type (cell or landline), country, and network status.
Using a bulk phone number validator is easy. All you need to do is register for a free trial and upload your phone number list. The entire process takes less than five minutes.

Why Do You Need Bulk Phone Verification?

Phone validation is an important part of any company's sales and marketing process. The ability to reach a potential or existing client is important for any business to be successful.

When a wrong number is on the phone list, it can cost a business lots of time and money while keeping existing clients unsatisfied.

It is of course possible to check the each number's validity manually. However, the process is very time-consuming. Even if you have only a few numbers, you still need to call each one and speak to each person. This could make your clients feel frustrated since validation needs to be done on a regular basis.

If you have more than a few numbers, individual validation will take a long time. That's why bulk validation tools are in high demand. With time, each businesses' contact list grows. To accommodate the rising demand for validation, you can take advantage of the in-bulk verification tool.

Benefits of Using Bulk Phone Number Validation

When you need to validate a list of phone numbers, you need an in-bulk validation tool. Such tools are specifically created to check large batches of contacts in real time. The automated process allows your team to save time and money while working with a clean list at all times.

Key benefits of using an in-bulk phone validator include:

  • Saved time – you don't need to check each number individually. In-bulk validation takes only a few minutes.
  • Saved money – each wrong number your team members call costs your business a certain amount of money. Not just because you are paying a telco provider but because it keeps your employees from focusing on core tasks.
  • Maintain reputation – each time you call the wrong number, you risk getting blacklisted. Meanwhile, a person who is waiting for your call gets frustrated. Each wrong number on your list is a missed chance to close a deal with a client.
  • Improved marketing ROI – once you get a client's phone number, you can start applying your marketing strategy. Invalid phone numbers keep you from building an effective campaign.
In-bulk phone number validation is an excellent way to check large batches of contacts while allowing your team to focus on other important tasks.
